THE SAFETY REPORT ASSESSMENT MANUAL (SRAM) – 2015
FOREWORD
ABOUT THIS GUIDANCE
This is the COMAH Competent Authority’s (CA)1 internally-targeted guidance on the
assessment of COMAH safety reports. It describes the framework within which the CA
undertakes the assessment of safety reports and the processes its staff should follow in
assessing safety reports submitted to them by operators of upper-tier COMAH
establishments, pursuant to regulations 9 and 10 of the Control of Major Accident Hazards
Regulations 2015 (COMAH).
The Safety Report Assessment Manual is not guidance to COMAH Operators on how to
write safety reports.
Following this guidance enables the CA to achieve consistency in its delivery of safety report
assessment, and internal review and audit functions should refer to it when evaluating the
CA’s performance in assessing safety reports.
SCOPE OF THIS GUIDANCE

This guidance covers the assessment of all COMAH safety reports and / or their component
parts. The assessment cycle begins with pre-receipt activities and ends with the CA
communicating the conclusions of its examination of the safety report to the COMAH
operator.
USING THIS GUIDANCE

The SRAM provides an overview of the safety report assessment cycle and then further
detail on each of the processes that should be undertaken by relevant CA staff. There are
several appendices which are referenced throughout the main text and these should be
referred to, as necessary, by the reader.
The assessment processes apply in broadly the same way to all assessment work but the
amount of effort and resource required will depend upon the type of safety report to be
submitted and the relative risk posed by the establishment.
1
The competent authority for an establishment is HSE, or the Office for Nuclear Regulation (ONR) for nuclear
establishments, together with the appropriate agency. In England the competent authority is HSE or ONR and
the Environment Agency (EA); in Scotland it is HSE or ONR and the Scottish Environment Protection Agency
(SEPA); and in Wales it is HSE or ONR and Natural Resources Body for Wales (NRW).

1. INTRODUCTION TO SAFETY REPORT ASSESSMENT
1.1 BACKGROUND
The COMAH Competent Authority uses a structured assessment approach to examine the content
of COMAH safety reports. The three key elements of this approach are described in detail below:
 The duties and actions of the CA; and

 The limitations of safety report assessment; and
 The CA’s wider expectations of COMAH operators in regard to their safety reports.
1.2 THE DUTIES AND ACTIONS OF THE COMAH COMPETENT AUTHORITY
1 The COMAH Competent Authority (CA) has a duty to examine COMAH safety reports
and this is an integrated part of its wider intervention strategy for upper-tier COMAH
establishments.
2 The CA examines safety reports using a structured assessment process to reach

conclusions on the extent to which new and revised content of the safety report
meets the relevant requirements of Regulations 8, 9, 10 and Schedules 2 and 3 of
the COMAH Regulations 2015.
The CA uses discipline specific assessment criteria and guidance on how to use them,
in Sections 8-14 of this SRAM document.
3 The CA must decide if the content of the safety report indicates a potential serious
deficiency in the measures taken by the operator for the prevention and mitigation
of major accidents;
In such circumstances the CA would visit the establishment to verify if the actual
arrangements on site are seriously deficient and if necessary prohibit the bringing
into operation, or continued operation, of the establishment, or any part of it, in
accordance with regulation 23 of COMAH.
4 The CA will use Pre-Receipt Activities to reach agreement with operators upon the
requirements for safety report submissions.
5 The CA must communicate the conclusions of its examination of the safety report to
the COMAH Operator within a reasonable period of time.
The CA publishes its guidance on how long a safety report assessment should take to
enable conclusions to be communicated to the COMAH Operator.
Page 1
1.3 LIMITATIONS OF ASSESSMENT
1 The assessment of a safety report does not ensure that the necessary measures have
been taken to manage major accident hazards at an establishment.
Actual on site conditions can only be verified through inspection.
2 The content of a safety report should be taken at face value and presumed to be
accurate unless there is clear evidence to the contrary (e.g. conflicting statements in
the report or local knowledge of the assessment team).
3 The depth of assessment should be proportionate to the level of risk and the extent
to which the information contained in the safety report is new to the CA.
4 The purpose of assessment is not to achieve a perfect safety report. Where a report
is found to be deficient in some way the assessment team will judge its importance
to the overall control of major accident hazards and, within the CA’s wider
enforcement strategy, determine if any further action is required to remedy the
deficiency.
1.4 THE COMPETENT AUTHORITY’S EXPECTATIONS OF COMAH OPERATORS IN REGARD TO

THEIR SAFETY REPORTS
1 Operators provide necessary assistance by entering into pre-receipt activities with

the CA to reach agreement upon the requirements for a safety report submission.
2 Operators send safety reports to the CA which satisfy the relevant requirements of
Regulations 8, 9 and 10 and Schedules 2 and 3; in doing so they fully take into
account the Pre-Receipt Agreement reached between themselves and the CA.
3 Operators sending a safety report to the CA which has been reviewed and revised
under Regulation 10(1) of COMAH, have clearly highlighted the changes in that
report and provided a narrative account of the review undertaken and changes that
have been made to the safety report;
4 Where changes are planned at an establishment that indicate the need for an
operator to prepare a modification report, they inform the CA at the earliest
opportunity and send the modification report to the CA in advance of the
modification coming into effect.

1.5 A SUMMARY OF THE SAFETY REPORT ASSESSMENT CYCLE PROCESSES
The work to examine a safety report is undertaken by staff from the CA who are trained in and
competent to work through the safety report assessment cycle which consists of five stages, as
summarised in Figure 1 below:

Figure:1 – Summary of the safety report assessment cycle
Each stage must be completed before moving on to the next one, though the amount of work
required by the CA and the timescales within which it should be completed will depend upon the
nature of the COMAH establishment and the type of safety report which is to be submitted.

Figure: 2 – Summary of the safety report management cycle
The Pre-Receipt stage is managed by the COMAH Intervention Manager and the
assessment process from ‘Receipt’ through to ‘Conclusions’ managed by the
Assessment Manager – both roles are usually undertaken by the same person.
Page 3
1.6. TERMINOLOGY
 ‘HSE’ this term includes HSE and ONR staff

 ‘COMAH Intervention Manager’ this role may be completed by HSE, or EA/SEPA/NRW staff
agreed locally by the relevant operational teams; however for the purposes of this
guidance it has been assumed that this role is being fulfilled by HSE staff.
 ‘Assessment Manager’ this role may be completed by HSE, or EA/SEPA/NRW staff agreed
locally by the relevant operational teams; however for the purposes of this guidance it has
been assumed that this role is being fulfilled by HSE staff.
 ‘Discipline Specialists’ this refers to any specialists staff who take part in the safety report
assessment including environmental assessors
 ‘Environmental Assessment’ this assessment is generally led by the principle
EA/SEPA/NRW authorised person / assessor who manages any additional environmental
specialist assessment requirements which may be needed e.g. groundwater specialists,
conservation specialists etc.
 ‘Regulatory Assessment’ this refers to three assessments Descriptive, MAPP and Safety
Management Systems, and Emergency Preparedness which are generally completed by
HSE staff. Where the Assessment Manager role is fulfilled by HSE it is generally this role
that completes these three assessments. Alternatives to this structure may be agreed
locally.
The Safety Report Assessment Manual is not guidance to COMAH Operators on how
to write safety reports.
The key points of each stage of the assessment cycle are as follows:
1.7. PRE-RECEIPT ACTIVITIES

 All safety report submissions should have a Pre-Receipt Meeting.
This meeting need not be a standalone meeting in the intervention plan but could form
part of another intervention’s agenda.
Where safety reports have been assessed and all criterion met, a pre receipt meeting
should still be held with the operator to establish whether any revisions will be made to
the safety report and whether these may need assessing. Where no revisions are to be
made the COMAH Intervention Manager should ensure that the operator sends a letter to
the CA confirming this position on or before the agreed review date.
 The COMAH Intervention Manager and operator finalise the Pre-Receipt Agreement within
4 weeks of the pre-receipt meeting.
Page 4
For 5 yearly reviews of safety reports:
 The Pre-Receipt Meeting should happen 1 year in advance of the planned submission of
the report to the CA by the operator;
 The COMAH Intervention Manager considers and shares information held by the CA which
may be relevant to the safety report review to be undertaken by the operator;
 The COMAH Intervention Manager should clearly communicate to the COMAH operator,
the benefits of them providing the CA with a narrative summary of the review undertaken
and changes made to their safety report;
 The operator should clearly highlight new and revised content.
 The operator should be advised that the pre-receipt agreement does not remove the duty
on them to provide information within the revised safety report that satisfies regulations 8,
9 and 10 together with Schedules 2 and 3. A standard paragraph should be included in the
pre-receipt agreement letter
For “New” and “Other” Establishments (as defined) and Modifications to Existing
Establishment reports:
 A Pre-Receipt Meeting or a preliminary meeting to advise the operator of the pre-receipt
process should happen within 4 weeks of the operator’s original enquiry;
 Relevant discipline specialists where appropriate should attend Pre-Receipt Meetings for
New and Other Establishments and do so as required for Modifications to existing safety
reports;
 Pre-Receipt should be led by the assigned COMAH Intervention Manager but assessors
attending for the CA need not be those who may later carry out the assessment or future
inspection work.
 For rolling submissions, the Pre-Receipt Agreement may be incrementally updated.
Effect on COMAH Intervention Planning
 On the basis of the Pre-Receipt Agreement the COMAH Intervention Manager bids for the
required assessment resource i.e. those for whom there should be new or revised content
to assess;
The resourcing priorities for safety report work are reflected in the CA’s operational
guidance for intervention planning which is updated and issued annually.
1.8. RECEIPT OF SAFETY REPORT SUBMISSION

 The COMAH Intervention Manager is usually the Assessment Manager.
 The HSE Safety Report Administrator will receive the report on behalf of the CA and take
the necessary steps to set up the assessment work on the CA shared database e.g. COIN.
Page 5
Completeness Check
 Existing establishment safety reports – this is done by the Assessment Manager only;
 New / Other Establishment Reports – led by Assessment Manager with other discipline
specialist assessor input for rolling submissions, where necessary;
 Confirm presence of basic elements of safety report and extent to which new / revised
content reflects the Pre-Receipt Agreement;
 Confirm that a narrative summary of the review and revisions have been included;
 Confirm that revisions and new content have been highlighted.
Early Predictive Screen

 HSE Predictive discipline specialist assessor and EA/SEPA/NRW assessors usually undertake
this for new and other establishment safety reports only.
1.9 ASSESSMENT PLANNING

Assessment Manager
 Drafts and maintains assessment plan;
 Arranges assessment planning meeting (telecon, VC, face to face etc.);
 Issues final Assessment Plan before assessment begins.
1.10 ASSESSING THE SAFETY REPORT
Safety report content for assessment is sampled using the CA agreed assessment
criteria and should be taken at face value (see comments in 1.3 also).
Assessment is of new and revised content in the safety report.
 The CA will assess a safety report where it contains new and revised content;
 The required discipline specialist assessment team resource will be based upon the scope
of changes described within the Pre-Receipt Agreement.
Use SRAM 2015 Assessment Criteria and Guidance

 ‘Criterion Met’ - where the assessment or technical read through of the existing safety
report has an assessment criteria recorded as being met or satisfied, the ‘new’ safety
report submission should not be reassessed against that criteria unless one or more of the
following conditions are met:
 The operator has added to or revised the relevant content; or
 Where COMAH 2015 adds a new requirement which was not previously included in
COMAH 1999; or
 The assessor has evidence which contradicts the content of the safety report e.g.
inspection and investigation conclusions.
Page 6
Use of Other Relevant Sources of Information
 Assessors must be transparent about their use of any other relevant sources of
information, these could be for example, the current Technical Assessment Record or
where appropriate the last Technical Demonstrations Record. Use of other relevant
sources should be declared and recorded , within the relevant criterion section(s) of the
assessment record.
1.11 ASSESSMENT CONCLUSIONS MEETING

There must be a conclusions meeting for every type of safety report assessment
All members of the assessment team must attend the meeting
Deadlines for Conclusion of Assessment by the CA (from date of receipt):
Existing Establishment
 5 Year Revisions = 4 Months (1 month Completeness + 3 months Assessment);
 5 Year Full Rewrite = within 1 year but 6 months from start of assessment;
 Modification = 4 months [complexity can result in longer timetable]
New Establishment [complexity can result in longer timetable]
 Pre-Construction = 3 months;
 Pre-Operation = 3 months;
 Pre-Modification = 6 Months (where a modification of a non-COMAH site or an existing
lower tier establishment results in COMAH becoming relevant);
 Other Establishment = within 1 year but 6 months from start of assessment. Note: Other
Establishments have two years from the date on which COMAH applies to prepare a safety
report. This does not exclude inspection in the intervening period.
Page 7
2. PRE-RECEIPT ACTIVITIES
In respect to their COMAH duty to examine all safety reports submitted by COMAH operators, the
CA undertakes the following Pre-Receipt Activities:
 Resource Planning –safety report submission plans and COMAH Intervention Plans
 Pre-Receipt Meetings – work undertaken to ensure that information is shared between
the CA and the COMAH operator to provide optimal conditions for the report to meet the
minimum requirements of COMAH for content and purposes.
2.1 Resource Planning

2.1.1. Purpose
To plan and co–ordinate the work to be done in support of safety report assessment, and to
ensure the necessary resources are allocated through intervention planning arrangements.
2.1.2. Five Year Safety Report Submission Plan
Step Action – Responsibility
1 Five Year Plan

HSE Regulatory Team Leaders (with Admin assistance)
Prepare and maintain a team ‘five year safety report submission plan’ showing all
anticipated safety report submissions in respect of COMAH upper-tier
establishments and the expected submission dates for the safety reports. This
should be shared where necessary with EA/SEPA/NRW teams.
ongoing basis
2 Identify Safety Report Submissions
HSE Regulatory Team Leaders and COMAH Intervention Managers
Consult with operators of existing establishments and monitor COMAH
notifications, to identify any forthcoming safety report submissions and / or
changes and record these on the team five year safety report submission plan and
corresponding Priorities for Inspection planning (PIP) records
throughout work-year
3 Advise of Changes Relevant to Safety Reports
Operational Strategy and Policy Units
Advise the Competent Authority’s operations units of forthcoming changes to
legislation, or other factors, that may impact on the duty to send and / or examine
a safety report.
Page 8
2.1.3. Safety Report Activity and COMAH Intervention Plans
1 Intervention Plans Support Safety Report Activity

HSE Regulatory Team Leaders and EA/NRW/SEPA Team Leaders
Ensure that COMAH Intervention Plans adequately reflect the CA resources
required to support pre-receipt and assessment activity for the COMAH safety
report submission expected.
In line with operational intervention planning guidance
2 Identify Resources Required for Pre-Receipt and Assessment work
COMAH Intervention Managers
Provide HSE Regulatory Team Leaders with sufficient information to support safety
report pre-receipt and assessment activity for intervention planning. This includes:
 Confirmation of the required discipline specialist types to support pre-receipt
activity for safety report submissions from New and Other Establishments and
Modification reports in respect of Existing Establishments; and
 Confirmation of the resource involvement of predictive and environment
assessors in 5 yearly review pre-receipt meetings; and
 Following the pre-receipt meeting, confirmation of the required discipline
specialist assessment team composition in respect of an operator’s safety
report submission.
3 Decide who leads Pre-Receipt and who will be Assessment Manager
HSE Regulatory Team Leaders and EA/NRW/SEPA Team Leaders (as necessary)
The COMAH Intervention Manager for an establishment will lead on Pre-Receipt
Activities and usually also be the Assessment Manager in respect of the safety
report submission. There may though, be good reasons where this is not the case,
for example:
 Where the COMAH Intervention Manager is an authorised person from one of
EA, NRW or SEPA - the CA will need to confirm that the COMAH Intervention
Manager will lead the Pre-Receipt work and that they will be the Assessment
Manager e.g. where revisions to the safety report are purely environmental; or
 For operational or resourcing issues, the work may be assigned to an HSE
Regulatory Inspector who is not also the appointed COMAH Intervention
Manager.
The decision should be made at a local level and recorded on the relevant COMAH
Intervention Plan and the team ‘Five Year Safety Report Submissions Plan’.
Page 9
Where the existing COMAH Intervention Manager will not carry out the pre-receipt
work, the decision should be communicated to the COMAH operator concerned at
the earliest opportunity.
[The SR Administrator should be informed so that the relevant COIN records can be
updated and the correct details are sent in the ‘Receipt of a Safety Report’ letter to
the Operator who submitted the safety report.]
4 Specialist and Environment Resource for Pre-Receipt and Assessment
HSE Discipline Specialist Team Leaders and EA/NRW/SEPA Team Leaders
Where the COMAH Intervention Plan indicates a resource request for their
technical discipline in relation to a safety report submission, the relevant Team
Leaders should identify the assessors to fill the required roles for the identified
assessment and pre-receipt work. They should confirm these names to the
relevant HSE Regulatory Team Leader, for inclusion in the Safety Report
Assessment Plan.
In accordance with timetable set out in Intervention planning guidance
5 Confirm Assessment Team
HSE Regulatory Team Leaders
Provide the COMAH Intervention Manager with confirmation of the name of the
Assessment Manager and composition of Assessment Team.
As soon as resourcing has been agreed
6 Resourcing Unplanned Work
HSE Regulatory and Specialist Team Leaders, and EA/NRW/SEPA Team Leaders
Unplanned work – this refers to unexpected in-year changes
In accordance with COMAH Intervention Planning operational guidance, allocate
the necessary CA resources where previously unplanned safety report activity is
added to an updated COMAH Intervention Plan – typically this would be in
response to an in-year submission of a ‘modification report’ or a new entrant to
COMAH requiring the initial pre-receipt work.
This means flexibility in resourcing the work, the outcome of which could be an
Assessment Manager other than the appointed COMAH Intervention Manager and
/ or technical assessors involved in pre-receipt who do not then undertake the later
assessment or inspection work.
Ongoing throughout the work-year
Page 10
2.2 Pre-Receipt Meeting
2.2.1 Purpose
The Pre-Receipt Meeting is a key stage in the development of any safety report and it is important
to both the CA and the COMAH operator. The objective is to ensure that information is shared
between both parties in order to provide optimal conditions for the report to meet the minimum
requirements of COMAH for content and purposes; this should mean that there are no significant
gaps in the information presented and that the report is able to be progressed without issue to the
The pre-receipt stage contains a one-off meeting but the overall process should involve
ongoing dialogue, as necessary, between the COMAH operator and the COMAH
Intervention Manager until the safety report is sent to the Competent Authority.
assessment stage.
2.2.2 Timing of Pre-Receipt Meetings

The COMAH Intervention Manager and the operator should refer to the expected timetable below
for the Pre-Receipt Meeting when agreeing upon the exact date for the meeting.
Existing Establishments
Five Yearly Review Safety Report 1 year before the report submission date.
Modification Safety Report
New Establishments
within 4 weeks of operator’s original enquiry

Other Establishments
‘First’ Safety Report
2.2.3 Existing Establishment - Five Yearly Safety Report Review

Preparation for the Pre-Receipt Meeting
1a Documentation Review
COMAH Intervention Manager
The COMAH Intervention Manager reviews relevant documentation relating to the
current safety report, which would typically include the current:
 Technical Assessment Records;
 Technical Demonstration Records; [where relevant]
Page 11
 Further information formally requested and submitted during the last safety
report assessment;
 Conclusions records, including revision plans;
 Updated safety report documentation - sent by the operator in respect of
current assessment conclusions;
 A copy of the current COMAH Notification for the establishment;
 A copy of intervention actions that are relevant to the operator’s safety report
review;
 Where issues exist regarding the assessment outcomes of previous criterion
assessment then refer to section 8.2;
 Where a previous technical assessment record for a particular discipline has
not been completed then advice should be sought from a relevant discipline
specialist Team Leader as to whether the assessment should be completed e.g.
for human factors.
 In advance of the pre-receipt meeting, Discipline specialist assessors should
bring deficiencies in the previous assessment to the attention of the COMAH
Intervention Manager.
The review of these documents forms part of the preparations for engagement
with the establishment. Where appropriate, the COMAH Intervention Manager
should forward the current predictive assessment to the Predictive discipline
specialist assessor and the current environmental assessments to the appropriate
authorised person from EA/NRW/SEPA. The COMAH Intervention Manager should
consult as necessary with their counterpart in EA/NRW/SEPA and relevant
discipline Specialists in order to develop a thorough understanding of the material
that should be in scope of the operator’s safety report review.
At least 5-6 weeks in advance of the meeting
1b Recording the Documentation Review on COIN

On COIN, use the relevant site ‘Pre-Receipt Activities’ case created by the Safety
Report Administrator to capture all pre-receipt work. The Notes field should be
used to make a brief record of the pre-receipt activities as they occur.
In the Notes field make a clear record of the documentation reviewed. Although, it
is not necessary to attach copies of the actual documentation referenced
This is particularly important where the pre-receipt work is undertaken by staff
who do not go on to do the assessment or inspection work for the establishment.
At least 4 weeks in advance of the meeting
Page 12
2 Sharing Information with the Operator
Following the documentation review, the COMAH Intervention Manager should
share the information the CA believes to be in scope of the operator’s review of
the establishment’s safety report.
no later than 4 weeks in advance of the Pre-Receipt Meeting.
3 Decide who Should Attend the Meeting
COMAH Intervention Manager, Predictive discipline specialist assessor and
EA/NRW/SEPA Authorised Person
The COMAH Intervention Manager* leads the meeting and they may be
accompanied by a Predictive Assessor and an authorised person from
EA/NRW/SEPA. The respective discipline specialist assessors should proactively
indicate that they also need to attend after taking into account local site
knowledge, complexity of the establishment, anticipated changes to the safety
report and CA operational priorities.
The CA expects the COMAH operator to provide competent personnel for the
meeting and it is good practice to include any representatives from consultants if
they are being used for the review and revision process.
[*CIM usually leads but refer to 2.1.3(3) for examples where this may not happen.]
Before the agenda is agreed
4 Agree Meeting Agenda
The COMAH Intervention Manager and the operator should agree the agenda for
the Pre-Receipt Meeting. For an example agenda please refer to SRAM 01 – PRE-
RECEIPT - PRM Agenda - 5 yearly review.
no later than 4 weeks in advance of the Pre-Receipt Meeting
2.2.4 Existing Establishment - Five Yearly Safety Report Review

The Pre-Receipt Meeting and Outcomes
1 Attend Pre-Receipt Meeting

COMAH Intervention Manager with Predictive and EA/NRW/SEPA as appropriate.
The COMAH Intervention Manager leads the meeting in accordance with the
agenda and makes a record of the discussion and outcomes on which the CA and
the operator have reached agreement. These should be:
a) the scope and depth of the review and revised information required;
b) how the revised information will be presented in the report;
Page 13
c) the requirements for a narrative report on the changes made;
d) the submission date;
e) the required number of copies and format e.g. disc versus hard copies of the
report needed for the assessment work.
2 Pre-Receipt Agreement and Covering Letter

COMAH Intervention Manager and Operator
The COMAH Intervention Manager and Operator should finalise a Pre-Receipt
Agreement within 4 weeks of the site meeting to reflect the outcomes of the
meeting. SRAM 05 – PRA – Pre-Receipt Agreement should be used for this purpose.
When the Pre Receipt Agreement is finalised, the COMAH Intervention Manager
should send a covering letter to the operator to confirm the CA’s expectation that
the safety report submission will fully meet the undertakings set out in the pre-
receipt agreement. SRAM 06 – PRA – Pre-Receipt Agreement Letter, contains
instructions on the content of the letter.
The agreement may need to be revised by the COMAH Intervention Manager in the
time between the meeting and the report submission. Significant changes to the
Pre Receipt agreement should be discussed with relevant Team Leaders
particularly if the changes are likely to require increased discipline specialist
resource.
no later than1 month after the Pre-Receipt Meeting
3 Recording the Pre-Receipt Meeting work on COIN
Record all work on the ‘Pre-Receipt Activities’ Case.
The meeting should be recorded on COIN as a brief contact report typed into the
Notes field (stating who attended, where, and for what purpose).
Attach the Pre-Receipt Agreement and covering letter to the Case with a note to
confirm when and how they were sent to the operator.
within 2 weeks of sending the covering letter and Pre-Receipt Agreement
4 Determining Assessment Team Composition
On the basis of the Pre-Receipt Agreement, the COMAH Intervention Manager
must determine the composition of the assessment team required to examine the
planned safety report submission. The key points being, where revisions /
additions are likely to be made, and which discipline specialists are likely to be in
scope of these changes. As necessary, they should seek advice from relevant
discipline specialists, to enable an informed bid to be made for resources during
the intervention planning process.
Page 14
To do this the COMAH Intervention Manager will need to amend the COMAH
Intervention Plan and provide information to the Regulatory Team Leader to allow the
team ‘five year safety report submission plan’ to be updated.
2.2.5 New or Other Establishment Safety Report

Initial Pre-Receipt Activity
The Regulatory Team Leader in conjunction with the relevant EA/SEPA/NRW Team Leader will
appoint a COMAH Intervention Manager for the new / other establishment and they should lead
on the pre-receipt activity with the operator.
The CA must begin discussions with a New / Other Establishment at the earliest
opportunity. It is vital that the CA and operator both understand the establishment’s
basis for entering upper tier COMAH and the resultant duties on both parties.
New Establishments:
New Entrants to COMAH
Where a new upper-tier establishment was not previously a lower tier COMAH
establishment, the initial interaction between the CA and the operator should be guided
by the framework for new entrants into COMAH (Understanding COMAH - Arrangements
for supporting businesses moving into COMAH).
This engagement should establish a reasonable mutual understanding of the operational
timetable for the establishment to meet its duties under COMAH, the nature of the new
entrant’s activities in scope of COMAH and the duties with which they must comply. One
of which is the preparation and submission of a COMAH safety report but very closely
related to that duty is the need to submit a notification under COMAH and to have
obtained Hazardous Substances Consent, where relevant to do so. Both of these can
impact upon the submission timetable for the safety report.
COMAH Establishment moves from lower tier to upper tier
Where the new upper-tier establishment was previously a lower tier establishment, the
approach should be similar to that for new entrants to COMAH, with the focus being on
the outcomes from the initial interaction between the CA and the operator. Again the CA
should establish a reasonable mutual understanding of the operational timetable for the
establishment to meet its duties under COMAH, the nature of the new upper-tier
establishment’s activities in scope of COMAH and any additional duties with which they
must comply.
Page 15
Other Establishments
The Other Establishment may have previously been a lower tier establishment or a non-
COMAH site of operation. The approach to the pre-receipt activity with the establishment
is the same as for the New Establishments described above, although the Other
establishment has two years to prepare and submit a safety report.
The key point to note is that the entry into COMAH of the Other Establishment is not an
event that will have been planned for by the operator and this may have an impact upon
their preparedness for the transition.

1 Confirm Pre-Receipt Team Resource

HSE Regulatory and Discipline Specialist Team Leaders, and EA/NRW/SEPA Team
Leaders
Agree upon the identity of the specialist disciplines and discipline specialists who
will be resourced to undertake the pre-receipt work with the operator. HSE
Regulatory Team Leader should confirm the arrangements with the appointed
COMAH Intervention Manager.
No later than 2 weeks before the first Pre-Receipt Meeting

2 Sharing of Documentation with Pre-Receipt Team
The COMAH Intervention Manager should circulate any relevant documentation that
has been received from the operator of the new / other establishment. This could
be a COMAH notification, project overview documentation, or hazardous
substance consent details.
The basic aim is to ensure that the Pre-Receipt team are informed as fully as
possible before attending site.
3 Recording the work on COIN

On COIN, use the ‘Pre-Receipt Activities’ case to capture all pre-receipt work. The
Notes field should be used to make a brief record of the pre-receipt activities as
they occur.
In the Notes field make a clear record of the documentation reviewed. Do not
attach copies of the actual documentation referenced.

5 Communicate with HSE Predictive Hazardous Substance Consent Risk Assessors

(CEMHD5)
Where an establishment is making an application for hazardous substances
consent in relation to their entry into upper tier COMAH the COMAH Intervention
Manager needs to communicate proactively with CEMHD5 on the progress of their
advice in relation to the consent application. Delays on consulting on hazardous
substance consent advice can delay safety report submission or impact the project
as a whole.

5 Communicate with HSE Predictive Hazardous Substance Consent Risk Assessors

(CEMHD5)

Where an establishment is making an application for hazardous substances
consent in relation to their proposed modification the COMAH Intervention Manager
needs to communicate proactively with CEMHD5 on the progress of their advice in
relation to the consent application. Delays on hazardous substance consent advice
HSC can delay safety report submission or impact the project as a whole.
Page 21
3. RECEIPT
The basic elements are to receive the safety report, do a high level check that the content is as
expected, and where necessary develop a basic understanding of the risk analysis presented in the
report. These steps are described below as: Receipt, Completeness Check and Early Predictive
Screening. This section also describes the steps to take if a report is not sent to the CA.
3.1 Receipt of Safety Report

3.1.1 Timing
The COMAH regulations provide some flexibility in terms of the timing for submission of safety
reports in respect of New and Other establishments but they are more prescriptive when the
safety reports are from existing establishments and in particular the submission of a safety report
for the Five Yearly Review. This should be taken into account when agreeing the submission date.
Once the operator has submitted their safety report documents to the CA, the clock starts ticking
on the time in which the CA must complete its examination of the safety report.
The safety report is therefore, expected to be submitted to the CA on the due date indicated in
the Pre-Receipt Agreement. It is good practice for the Assessment Manager to contact the
operator in advance of the submission date to check that there are no unforeseen problems and
that the report will be sent on the agreed date. Where there are issues, there is a clear
expectation that the operator proactively informs the Assessment Manager and explains the
reasons for any change to the submission date.
For five yearly review safety reports, it is important to note that the CA has no powers
within the COMAH regulations to agree a late submission date other than through the
use of an enforcement notice.
3.1.2 Receiving the Safety Report

This task is carried out by the HSE ‘Safety Report Administrator’ in accordance with their
operational guidance. The key elements of which are as follows:
 receive the operator’s safety report on behalf of the CA;
 convert the Pre-Receipt Activities Case into the Assessment Case / Service Order
combination;
 distribute copies of the safety report as instructed by the Assessment Manager; and
 keep a record of opinions expressed by the operator for possible future FOI / EIR requests.
Page 22
3.2 Completeness Check
3.2.1 Purpose
To confirm that the safety report contains the basic elements of Schedules 2 and 3 of COMAH
2015 and to determine the extent to which the new / revised content of the report reflects the
Pre-Receipt Agreement.
3.2.2. Doing the Completeness Check

The Assessment Manager carries out the completeness check for all safety report submissions,
though they should seek input from other discipline specialist assessors regarding submissions
from new and other establishments, and where necessary for existing establishment safety
reports.
The completeness check should be finished within 4 weeks of receiving a safety report.
For submissions from Other Establishments or 5-yearly revised safety reports from Existing
Establishments, which have been fully rewritten, the safety report assessment start date may be
postponed by up to 5 months from the date of receipt. In these circumstances, where the delay
will be of more than 1 month, the Assessment Manager should still carry out the completeness
check before entering the period of postponement. This is to avoid a long wait in dealing with any
significant errors or omissions that might necessitate returning the report to the operator.
3.2.3. Scope of the Completeness Check

The completeness check is not an assessment but it should typically cover the following aspects
regarding the submitted safety report:
 Relevant sections covering the key requirements of COMAH Schedules 2 and 3 are present;
 New inclusions and revised material been suitably identified to allow assessment;
 The operator has provided a narrative account summarising the revisions made;
 Where applicable, requirements of the previous ‘Revision Plan’ or relevant actions from CA
interventions been included;
 Where relevant, information has been provided about the review process carried out by
the operator and those involved;
 The extent to which the remaining requirements of the Pre-Receipt Agreement have been
incorporated.
3.2.4. The Outcome of the Completeness Check

The Assessment Manager must answer the question – “Can the safety report be progressed to the
assessment phase?” This can only be judged after checking against the aspects set out in 3.2.3
above. Where there is an omission of information or of a requirement in the pre-receipt
agreement, the Assessment Manager should determine, with appropriate advice from the
assessment team, if the safety report can be progressed to assessment.
Page 23
This reflects the fact that some omissions may be of greater significance than others depending
upon the particular establishment. If the report is not fit for purpose it will be returned to the
operator for revision and resubmission.
For Five Yearly Review and Revision Safety Reports
The absence of a narrative account on the revisions made is not sufficient reason to send the
safety report back to the operator but it will make it more likely that the assessment takes longer
to complete.
Where changes are not highlighted, the Assessment Manager should contact the operator to see if
a mistake has been made and allow them 1-2 weeks to remedy the situation through a suitable
resubmission – note the receipt date would then be reset. When an operator is not prepared to
send copies of the safety report with highlighted changes the report should be assessed in full as if
it were a fully rewritten submission. This may require the assessment team to be augmented by
the inclusion of assessment disciplines that were not previously resourced on the basis of the pre-
receipt agreement.
3.2.5. Recording the Completeness Check

Record the completeness check on the template in SRAM 07 – RECEIPT – Completeness Check
record. The final version of which should be attached to the assessment service order.
Inform the SR Administrator that the safety report is moving to the assessment stage and they will
send SRAM 09 RECEIPT - Key Information in Safety Report Letter – to Operator to the operator
and SRAM 10 RECEIPT - Key Information in Safety Report Letter – to EPA to the relevant
Emergency Planning Authority to let them know that the safety report has moved into
assessment.
3.3 Early Predictive Screening

3.3.1 Purpose
Early predictive screening aims to determine if the risk analysis appears suitable for the expected
hazards and risks and is sufficient for the CA’s overall assessment to continue, or that, where gaps
exist, these can be expected to be resolved on early provision of additional information that the
operator is likely to possess or be able to obtain rapidly. Apparent large omission of key
information in these areas is likely to have a major impact for further assessment of the safety
report across all disciplines and therefore needs to be identified at an early stage.
It is not an assessment of the safety report and the emphasis is on completing an EPS within a
short timescale
3.3.2. When to carry out Early Predictive Screening

In advance of a safety report submission the Assessment Manager Predictive and environmental
discipline specialist assessors will decide if an Early Predictive Screening (EPS) should be
Page 24
undertaken before the report is sent to other members of the Assessment Team. The decision
should be guided as follows:
 For a ‘New / Other’ Establishment safety report an EPS would normally be undertaken;
 Where a review of an Existing Establishment’s safety report has been submitted, it is
normally unnecessary to carry out an EPS unless the safety report has been extensively
rewritten and is essentially comprised of wholly new content e.g. where new
environmental MATTE demonstration information has been provided the environmental
assessor would typically undertake an EPS.
 When an Early Predictive Screening is to be carried out it should be finalised within the
completeness check timeframe.
3.3.3. Early Predictive Screening Record
All Early Predictive Screening should use SRAM 08 – RECEIPT - Early Predictive Screening Record
and where undertaken, the completed record should be forwarded to the Assessment Manager in
advance of the draft Assessment Plan being finalised.
3.4 Resubmission
After carrying out the completeness check the Assessment Manager in conjunction with the
Assessment Team, may consider the safety report does not contain the basic elements of a safety
report. If this is the case then a decision should be taken on whether the operator should be
required to revise and resubmit the report.
These steps should be followed:
1 Meet with Operator and Issue an Improvement Notice

Assessment Manager / Relevant Authorised Person from EA/NRW/SEPA
Where safety report shortcomings and omissions are substantial and numerous
rather than minutiae and few, and are clearly linked to the requirements of the
COMAH Regulations (regulations 8, 9, and 10, and Schedules 2 and 3), arrange an
immediate meeting with the operator, including a representative at director level
or senior site manager, to explain the shortcomings and missing information and
require revision and resubmission of the safety report within an agreed timescale
e.g. six months.
This would usually require an Improvement Notice to be served that requires
resubmission of the safety report, in accordance with the CA partner’s
enforcement policies.
2 Assessment Manager
Write to the operator, using SRAM 11 – RECEIPT – Key information Not in Safety
Page 25
Report Letter, giving the deadline for the revision and resubmission of the safety
report detailing and highlighting revisions to be made to correct missing key
information or shortcomings in the risk analysis.
Where an Improvement Notice is being served it should be sent with the letter.
Inform employees or their representatives that revision and resubmission has been
required resulting in the assessment process being postponed, therefore the
assessment conclusions will be delayed as a result.
3.5 Failure To Send A Safety Report

3.5.1 Purpose
A description of the action to be taken when an operator does not submit a safety report to the
CA; or fails to notify the CA of the details of any safety report review which resulting in revisions
not being made to a safety report.
3.5.2 Steps to be taken by the Assessment Manager

The Assessment Manager must contact the operator to establish the reasons for any delay and
having done so, should take the following action as appropriate:
For 5 Yearly Review Safety Reports
 Where the report or details of the review cannot immediately be sent to the CA, then
agree a deadline for submission with the operator, of not more than three weeks later
than the original due date;
 Serve an Improvement Notice where a deadline within 3 weeks of the due date cannot be
agreed, or where a new deadline (as above) has also been missed. The enforcement
policies of the relevant CA partners should be followed;
For New or Other Establishments
 Where an operator does not produce a safety report as required by the COMAH
Regulations, then consider the requirements for prohibition under reg. 23(2) of COMAH.
In all cases, inform other members of the assessment team of the delay and the expected date of
submission.
Ensure that any instance of an overdue safety report is recorded in accordance with Performance
Framework expectations and as an adverse dutyholder factor when using the Enforcement
Management Model.
Page 26
4. ASSESSMENT PLANNING
Purpose
There must be an Assessment Plan for each safety report submission, which confirms the
parameters within which the assessment should be carried out. The Assessment Manager owns
and drafts the Assessment Plan with appropriate input from the Assessment Team via an
Assessment Planning Meeting. The final plan is approved by the Team Leader of the Assessment
Manager. The detail of the plan should appropriately reflect the type of safety report under
examination and be proportionate to the establishment concerned, whilst covering the following
key points:
 Summary Details of the Safety Report
 Relevant background information for the assessment
 Which content is in scope of assessment and by whom
 The resource allocated through the COMAH Intervention Plan
 Key dates and actions for the Assessment Team
The Pre-Receipt agreement is a key source of information when drafting an assessment plan.
4.1 Assessment Planning Meeting

4.1.1 Timing
The Assessment Manager should arrange for the assessment planning meeting to be held within 4
weeks of receipt of the safety report. The assessment planning meeting may go ahead when the
Completeness Check has been carried out and has found that the report may be progressed to the
assessment stage.
4.1.2 Attendance
The assessment planning meeting should be attended by all of the assessment team but it is
acceptable to make use of video / teleconference facilities as necessary. However, for safety
report submissions from New and Other Establishments, the meeting of the assessment team
should be face to face; although subsequent interim or follow up meetings need not be.
Where a safety report has reached a third 5 year review then, due to the decreasing amount of
revisions per cycle it is permissible to agree the assessment plan by e-mail retaining all records to
ensure a clear audit trail.
4.1.3. Preparation
In advance of the meeting, the Assessment Manager should draft the Assessment Plan and
circulate it to the Assessment Team for discussion during the meeting. The template Assessment
Plan SRAM 12 – PLANNING ASSESSMENT – Assessment Plan Record should be used by the
Assessment Manager. If the establishment under assessment is part of group of sites who operate
under Lead Unit or Coordinating Inspector arrangements then more time will be needed for
assessment outcome agreement should revisions or similar be required, as these may need
further agreement before issue to the establishment involved. These requirements should be
allowed for within the assessment plan (see also section 6.2)
Page 27
4.1.4. The Meeting
The Assessment Manager chairs the Assessment Planning meeting, with the objectives of:
 signing off the target agenda and ensuring a coordinated approach by the assessors with
clarity on timings and resources to be used;
 agreeing upon how proportionality applies at the establishment in terms of depth and
scope of assessment; and
 highlighting the approach to dealing with further information requests, potential serious
deficiencies and actual significant omissions in SR content.
4.2 Elements of the Assessment Plan
4.2.1 Type of Safety Report Assessment
The extent of assessment for a given safety report is as follows:
Safety Report Type Assessment Type

Existing Establishment Highlighted Revisions Assessment
Five Yearly Review Safety Report unless the report is fully rewritten in which
case a full assessment should be undertaken.
Existing Establishment Full Assessment
New Establishment Full Assessment
Pre-Construction Safety Report but usually not of unchanged PCSR content
Pre-Operation Safety Report
Pre-Modification Safety Report
Other Establishment Full Assessment
‘First’ Safety Report
4.2.2 Deadlines for the Conclusion of Assessment by the CA (from date of receipt).
The Assessment Manager should base the Assessment Plan around the following deadlines for the
completion of assessment conclusions.
Safety Report Type Assessment Conclusions Sent To Operator

Existing Establishment 4 Months
5-Yearly Highlighted Revisions (1 month completeness + 3 months assessment)
Existing Establishment 6 months
5-Yearly Revision - Full Rewrite (1 month completeness + 6 months assessment,
but start of the assessment phase may be
postponed for up to 6 months from receipt)
Existing Establishment 4 Months
New Establishment
Page 28
Pre-Construction Safety Report 3 Months*
Pre-Operation Safety Report 3 Months*
Pre-Modification Safety Report 6 Months
[* complexity can result in longer timetable]
Other Establishment 6 months
‘First’ Safety Report (1 month completeness + 6 months assessment,
but start of the assessment phase may be
postponed for up to 6 months from receipt)
4.2.3 Pre-Construction Safety Reports and Pre-Operation Safety Reports

Pre-Construction Safety Report and Pre-Operation Safety Report deadlines are shorter because
the COMAH Regulations do not allow the operator to start construction or operation of a new
establishment until they have received the CA’s conclusions following examination of the PCSR
and POSR respectively.
The assessment of a Pre-Construction Safety Report allows the CA to communicate early

conclusions about the key hazard issues and associated control measures. This gives the operator
a better opportunity to take appropriate remedial action before it becomes too difficult or costly
to implement. Where operators provide a Pre-Construction Safety Report in the form of a rolling
submission of documents, it is important for the CA to provide interim conclusions on each stage
of the submission as quickly as possible to afford the best opportunity for the operator to take
remedial action.
Timescales for assessment of rolling submission Pre-Construction Safety Reports will be influenced
by the operator’s planned programme for the submission and cannot be subjected to a specific
time frame for assessment; however, the CA should not delay its examination of such reports.
The Pre-Construction Safety Report may be a standalone document or it could be appropriately

incorporated into the Pre-Operation Safety Report to constitute the complete safety report.
Therefore, when judging whether the report contains sufficient information, the information
provided by the operator in both the Pre-Construction Safety Report and the Pre-Operation Safety
Report needs to be considered. This is unless the operator specifies that the Pre-Operation Safety
Report is a fully comprehensive report, i.e. the Pre-Operation Safety Report replaces all previously
supplied information.
4.2.4 Composition of Assessment Team

The required assessment team resource will be based upon the scope of new and revised content
for the safety report as described within the Pre-Receipt Agreement and reflected in the COMAH
Intervention Plan for the establishment.
Page 29
4.2.5 Start Date for Assessment
The CA should start the assessment process without delay when it receives a safety report from an
operator of a New Establishment.
4.2.6 Delaying the Start of Assessment

For operational reasons, such as an unforeseen peak in resource demand, it may be necessary to
request a delay to the start of the assessment phase, not exceeding 6 months from receipt of the
safety report. This must be agreed by the Team Leaders of the Assessment Team, and can only be
used for the safety report submissions shown below:
 Other Establishment: ‘First’ Safety Report
 Existing Establishment: 5-Yearly Revision - Full Rewrite
The Assessment Manager should inform the Safety Report Administrator, add a note to the COIN
Assessment Service Order and inform the operator of the COMAH establishment of the delay and
the reasons for it.
4.2.7 Request for Further Information

In general, a request for further information should be limited to safety reports submitted in
respect of New / Other Establishments and when content required by Schedule 3 of the COMAH
Regulations has been omitted from the safety report.
A request is made on the basis that the information is either readily available or can be provided
by the operator within 4 weeks of the request being made.
4.3 Assessment Scope

The assessment will typically be of new and revised safety report content only, defined as below:
 A safety report may be comprised of unchanged, new or revised content.
 For a safety report from an ‘Other Establishment’ or a ‘New Establishment’ at either the
pre-construction or pre-modification stage, the report content would be classed as new.
 A ‘New Establishment’s pre-operation safety report is comprised of unchanged, new and
revised content. The Assessment Manager should advise the operator to indicate material
that is unchanged from pre-construction. Where unchanged content from the pre-
construction safety report was previously assessed and found to meet relevant criteria,
then it should not be reassessed unless there is a good reason to do so.
 For Existing Establishments, five yearly revised reports are comprised of unchanged
content and additions or amendments that are highlighted or for a fully rewritten report
the content is all new.
 A modification report for an existing establishment would typically be comprised of new
content.
Page 30
Exceptions to this approach are:
 For Pre-Construction Safety Report all parts should normally be assessed and sampling is
to be on an exceptional basis;
 Where the CA has evidence that contradicts the content of the safety report;
 Where a new requirement of the COMAH 2015 regulations has not been accounted for in
the report prepared under the COMAH 1999 (as amended) regulations.
4.4 Proportionality of Assessment
4.4.1 Factors affecting proportionality

A key principle of the safety report assessment process is that it is proportionate to the level of
hazard and risk associated with the establishment to which it relates. The proportionality of
assessment of a safety report should broadly match the proportionality required of the operator’s
risk assessment for the establishment. This is essentially determined by the severity of the worst
possible consequences should the worst case scenario occur, and the levels of risk that remain
after taking into account the prevention and mitigation measures that the operator has put in
place. The following factors are therefore important:
a) The scale (inventory, vessel sizes, etc.) and nature of the hazards (hazardous properties,
toxicity, flammability, hazard to the environment, etc.);
b) The location of the establishment in relation to external populations, environmentally
sensitive receptors and other risk influencing factors such as flood zones;
c) The density and types (vulnerability) of external populations (dwellings, hospitals, schools,
etc.) and types of environmentally sensitive receptors;
d) The number of people on the establishment;
e) The variation of residual individual risk with distance;
f) Escalation potential (e.g. domino effects in relation to neighbouring establishments); and,
g) The criticality of applied measures to achieving the claimed level of residual risk.
4.4.2 The decision-making process

The level of risk posed by the establishment should have an influence on the areas in which
assessors focus their attention. Information in the safety report should enable assessors to
understand site specific circumstances (on-site and off-site), so that a view on proportionality can
be reached. Decisions about proportionality should be made by the assessment team as a whole.
Where an early predictive screen has been completed, this will inform the decision making process
until a full predictive assessment has been carried out.
In the context of the Safety Report Assessment Manual, decisions about proportionality of
assessment mean considering both the breadth and depth of assessment.
Page 31
4.4.3 Breadth of assessment
The nature and spread of the hazards present at an establishment determines the breadth of
assessment. The assessment needs to consider a representative sample of the types of hazards
found. It will therefore need to have covered different plants, units, activities and containments
sufficient to reflect the varying nature of the hazards present, and the different nature of the
measures taken to control them. The assessment team should agree on the sample to be selected
and record their decision on the Assessment Plan.
4.4.4 Depth of assessment
The depth of assessment depends on the risk and one approach is to use the consequence extent
and severity information relating to a scenario to make judgements about the required depth of
assessment.
In considering the extent of a potential major accident the team will be looking at how big an
accident might be and take into account matters such as: thermal radiation dose; toxicity; dose;
quantity of hazardous material; and the range over which the effects extend for both people and
the environment, both internally and externally to the establishment. In considering the severity
of an accident the team will be looking at how severe the consequences of the accident might be.
This might be expressed in terms of numbers of fatalities or serious injuries, or harm to the
environment, etc. Such matters depend on the surrounding population and environment.
Establishments can be considered to fall on a scale between two extremes ranging from
unmanned sites with no surrounding population which are not in an environmentally sensitive
location to manned sites in the middle of a dense population and in a very sensitive environmental
location.
Low risk establishments:
For example, a simple establishment remote from population and sensitive environments with a
single dangerous substance presenting a limited range of hazards that may only require
description of the extent and severity of the worst case incidents plus a simple qualitative risk
assessment to demonstrate that the necessary prevention and mitigation measures are in place;
Medium risk establishments:
For example, a simple establishment in a sensitive location and presenting risks which may be
tolerable to people and the environment, for which a more detailed description of the extent and
severity of the worst case accidents is required, together with analysis to demonstrate that the
associated risks are as low as is reasonable practicable (ALARP);
High risk establishments:
For example a complex site with many processes and several hazardous materials in the vicinity of
centres of population and/or sensitive environments for which a much more detailed assessment
with quantification of the likelihood of the full range of hazardous releases and their
consequences, and possibly of the associated risks is needed;
Page 32
It follows that the safety reports for higher risk establishments should, in principle, be assessed to
a greater depth than those for establishments presenting lower risk .
4.5 Targeted Assessment Agenda

Details of the targeted assessment agenda are recorded in section 3 of the Assessment Plan. The
Assessment Manager’s proposals will be based on the pre-receipt agreement, completeness check
of the safety report and other background information such as the size and complexity of the
establishment; and the surrounding natural environment.
At the assessment planning meeting the assessment team should agree the level of risk presented
by the establishment (High/Medium/Low) in order to agree on a proportionate approach for the
assessment. CA site prioritisation scores can be used as a guide which may show a higher priority
for safety or the environment, meaning potential differences in the depth of assessment in these
areas. The team should discuss what this means for the report in terms of breadth and depth of
assessment, informed by any early observations made by the predictive and environmental
assessors where appropriate.
Full Assessment means that all safety report content is in scope to be selected for examination
against all relevant assessment criteria;
Revisions Assessment means only highlighted changes are assessed against relevant assessment
criteria.
Existing Establishment safety reports
For the assessment of revisions only in five yearly reviewed safety reports, the CA has a clear
expectation that the previous version of the establishment’s safety report has been fully assessed
and this will have followed a suitably targeted approach to breadth and depth of assessment. If
this is not the case for a particular assessment discipline e.g. no previous discipline assessment has
been completed, then it should be brought to the attention of the COMAH Intervention Manager
during the preparation for the pre-receipt meeting.
Page 33
5. ASSESSING THE SAFETY REPORT
Purpose
To instruct staff on how to organise, communicate, operate and record in line with the assessment
plan.
5.1 Work to the Assessment Plan
Step Action - Responsibility
1 Assess the Safety Report

Assessment Team
 Using the appropriate assessment criteria and guidance for your discipline,
assess the safety report in accordance with the Assessment Plan.
 Record your assessment on the appropriate Technical Assessment Record
template provided.
2 Completing the Assessment

Assessment Team
When the assessor has completed their assessment of the safety report they
should complete the ‘Conclusions Questions’ at the front of the Technical
Assessment Record template. These questions are specific to each assessment
discipline and reflect the relevant aspects of:
a) the minimum information required by Schedule 3; and
b) the purposes of Regulation 8 (taking into account the CA’s knowledge of the
establishment any additional intelligence obtained from the operator
during the assessment process);
The assessor should also complete the summary tables relating to:
 Requests For Further Information
 Proposed Interventions Arising From Safety Report Assessment
 Proposed Revision Plan Items
The assessor should write ‘none’ in each table where there is no text to be added.
3 COIN and Forwarding the Record
Assessment Team
Attach your completed Technical Assessment Record (including assessment
conclusions) to the Assessment Service Order on COIN and also send a copy to the
Assessment Manager and Assessment Team.
Page 34
Use of Other Relevant Sources of Information
Assessors must be transparent about their use of any other relevant sources of information, for
example the assessor may refer to a recent inspection report, the current Technical Assessment
Record or where appropriate the Technical Demonstrations Record. There may be other sources
of relevant information that could be referred to in the assessment but there is no need for the
assessor to actively seek out alternative information. Where these sources have been used these
should be recorded in the relevant criterion assessment text.
5.2 Issues Which May Arise During Assessment

These issues should be covered in the Assessment Plan at a high level but this section provides
greater detail on the steps to be taken by the Assessment Team members and in particular the
Assessment Manager.
5.2.1 Potential Serious Deficiency
Background
The assessment team or one of its assessors may find that the safety report describes measures
that appear to be seriously deficient for preventing or controlling the risks arising from a major
accident hazard. The assessment team will form a view about these measures within the
establishment’s wider control strategy and will balance them against the likelihood of the related
major accident hazards and their consequences when considering serious deficiency as applicable
to Regulation 23 of the COMAH Regulations 2015
Under Regulation 23 the CA has a duty to prohibit that part of the seriously deficient operation
which could lead to a major accident. The CA will visit the site to check whether the measures
signposted by the report are actually seriously deficient, before taking action as appropriate. It is
only the actual measures provided by the operator on the establishment that can be considered
‘seriously deficient’ under COMAH and not the report itself.
There is no legal precedent in health and safety legislation as to what serious deficiency might
mean. The assessment team must reach a consensus that a major gap or defect exists in the
measures provided, linked to prevention or limitation of a major accident, for serious deficiency to
be determined.
Assessors should not consider a measure to be seriously deficient just because it might be
reasonably practicable to achieve higher standards of protection. This would be a matter that
should be addressed during subsequent inspection.
The steps to follow on discovering a potential serious deficiency are:
1 Assessment Team
Where the assessment of safety report content reveals a potential serious
deficiency in conditions on site, the Assessment Manager should be informed
Page 35
without delay.
The Assessment Manager should discuss the issue with the Assessment Team
members and their Team Leader.
Contact the operator to check if the safety report content is actually correct. If the
wrong information has been included and the right information can be provided
promptly (i.e. within days) then ask for it to be sent as a matter of urgency.
At the same time arrange a visit to the establishment as soon as possible, to verify
the statements which indicated the potential serious deficiency. Assessment team
members should be involved as necessary.
If there is an actual serious deficiency or significant omission this should be dealt
with under Regulation 23 of the COMAH Regulations.
If the information in the safety report is incorrect, this should be remedied at the
earliest opportunity by the operator and a note made on the conclusions record.
5.2.2 A Request for Further Information

Background
An assessor may form an opinion that significant information, such as a particular requirement of
Schedules 2 or 3 of COMAH, has been omitted from a safety report. The assessor may, through
the Assessment Manager and following the arrangements set out in the Assessment Plan request
further information to be provided by the operator.
The information requested is expected to be readily available on the basis that the operator is
presumed to have conducted the necessary work in preparing the safety report. It is therefore
assumed that the operator can provide the requested information within four weeks and they
must be given the opportunity to do so. It is for the operator to say that they cannot produce
information when required, not for the assessor to assume they cannot provide it.
In order to effectively manage the assessment process in a timely manner the Assessment Team
should make only one (combined) request and that it should usually only be in respect of New or
Other Establishment Safety Reports. It should also be noted that requests for information are not
to be used to obtain information to resolve issues that would be regarded as inspection topics (i.e.
verification of demonstrations).
How to Request Further Information
1a Request for Further Information

Assessment Team
Assessors should send any further information requirements to the Assessment
Page 36
Manager in line with the timetable set out in the Assessment Plan.
Assessment Manager
Arrange, as necessary, a meeting of the assessment team to finalise the details of
the request for further information though…
1b Assessment Team
Consider holding a meeting with the operator as soon as possible, if it would be
more efficient for assessors to explain their information requests in this way.
Assessment Manager
Following the meeting, write to the operator to confirm the nature of any further
information obtained at the meeting, together with details of any additional
further information still required and the date by which it should be provided.
[SRAM 13 – Further Information Required Letter may be adapted for this purpose]
1c Assessment Manager
Where further information is required and a site meeting is not considered
appropriate, write to the operator using SRAM 13 – Further Information Required
Letter, with details of the required information and the date by which it should be
provided (which should be within 4 weeks).
When making a request for further information, assessors should ensure that:
a) The issue under consideration is clearly explained, preferably with an
outline of how the report fails to address the issue. Reference to the
relevant assessment criteria to which the deficiency relates and to the
relevant COMAH regulation(s) and/or schedule(s) should be made.
b) There is a clear link to how the further information relates to meeting the
required demonstrations, with reference to the regulations.
c) The nature of the required information that is expected in order to resolve
the issue(s) is indicated.
Make it clear to the operator that if the information is not received by the deadline
the assessment will continue to the conclusion stage without it.
1d Assessment Manager
Where further information has been requested, allow 4 weeks for receipt but
check on progress with the operator in advance of the deadline.
Where the information requested is not received within 4 weeks, speak to the
operator to ascertain whether it is likely to be provided within the next few days.
If the information is not forthcoming, notify the assessment team and instruct
them to proceed towards conclusion of the assessment without it.
Page 37
1e Assessment Manager
Where an operator has sent further information it must be allocated the same
reference number as the safety report under assessment.
Page 38
6. Assessment Conclusions
Purpose
The process of assessment is to establish that the relevant requirements of the regulations have
been appropriately addressed and, as far as can be reasonably determined from a prima facie
assessment of the report, that the operator has taken the necessary measures to prevent major
accidents and limit the consequences to human health and the environment.
Assessment is not a check or approval by the CA of the operator's plant and process design and
the conclusions of the assessment cannot be regarded as a statement that the CA has determined
that an establishment is 'safe'. The duty to ensure that an establishment is designed, constructed
and managed safely remains with the operator.
6.1 Concluding the Assessment
The safety report assessment may be concluded with issues arising from the assessment
remaining unresolved at the time of conclusion. Assessors should note that the assessment
process is only a part of the CA’s approach to COMAH regulation.
Where relevant, the assessment conclusions reached by the assessment team should clearly
describe why a particular demonstration has not been made and refer to the relevant assessment
criteria and to the specific COMAH Regulation or Schedule.
The steps to be followed for the Assessment Conclusions mainly centre on the meeting to discuss
and agree the conclusions. They are as follows:
6.2 Assessment Conclusions Meeting
Step Responsibility/Action
In advance of the meeting, draft and circulate to the Assessment Team a
collated version of the Assessment Record tables in relation to any request for
further information, Proposed Interventions and Proposed Revision Plan
Items. This will allow discussion of the priorities which arise from the
assessment.
Chair the meeting unless the Assessment Manager’s Team Leader is doing so.
Complete an outline of SRAM 23 – ASSESSMENT – Assessment Conclusions
Record.
2 Assessment Team
Attend the assessment conclusions meeting – attendance face to face, or via
video conference is permitted.
Page 39
3 Team Leader of Assessment Manager
Where necessary, chair the Assessment Conclusions Meeting (optional).
Sign off the conclusions record.
Signing off confirms management agreement that the conclusions have been
derived in accordance with the Safety Report Assessment Manual procedures,
are consistent with the technical assessment records and that any action
proposed is in accordance with the CA's enforcement principles i.e. targeting,
transparency, consistency and proportionality.
4 Assessment Team
Present conclusions for discussion.
In the case of a Pre-Construction Safety Report, agree issues for consideration
during assessment of the pre-operation part of the safety report.
In the case of a Pre-Operation Safety Report, agree conclusions on the
combined PCSR/POSR safety report.
Agree the common elements of the conclusions letter to the operator.
Propose topics for inclusion in the COMAH Intervention Plan.
Discuss cross-team issues with other team members, as appropriate.
Follow the disagreements resolution procedure (see section 7.2) if necessary.
5 Chair of the Meeting

Seek consensus from team members on conclusions and the priorities for any
remedial action by the operator.
Agree the common elements of the conclusions letter to the operator,
specifically any revision plan items or serious deficiencies
Discuss topics for inclusion in the intervention plan for the establishment
arising from consideration of the safety report.
Take action to resolve any disagreements using the resolution arrangements in
section 7.2.
If serious deficiencies in establishment internal conditions are signposted at
the conclusions stage, e.g. as a result of accumulated evidence from more than
one assessor, arrange a visit to the establishment as soon as possible to make
enquiries with a view to prohibition under Regulation 23 of the COMAH
Regulations.
7 Assessment Team
Where significant shortfalls remain in the demonstrations, justifying follow-up
in the intervention plan, a revision plan for improving the report may be
Page 40
proposed in which case timescales for the provision of further information
should be agreed.
Draft the conclusions letter using SRAM 24 – ASSESSMENT – Assessment
Conclusions Letter, and share with the assessment team
For multi-establishment operators, send a copy of the draft conclusions letter
to the Lead Unit/Co-coordinating inspector(s), including those of the Agency
where appropriate. Do this sufficiently early to allow input of relevant central
knowledge of the company to the final version of the conclusions letter.
Draw up the revision plan where appropriate, based on discussions at the
meeting
9 Assessment Team
Finalise assessment records and send them to the Assessment Manager in
order for them to be forwarded to the operator.
Finalise the Assessment Team Conclusions Record using SRAM 23 –
ASSESSMENT – Assessment Conclusions Record. If an issue was subject to
disagreements resolution then record details, including the person it was
referred to and the outcome (see Section 7.2).
Record inspection issues agreed.
Copy the conclusions letter to the Lead Unit/Co-coordinating Inspector where
relevant.
Send the following items:
 Conclusions letter
 Part 1 of the conclusions meeting record
 Safety report revision plan (where necessary), and
 Finalised assessment records
to the operator by the due date in the assessment plan (but not before any
disagreements have been resolved, in accordance with section 7.2), copying to
employees or their representatives.
Where appropriate, the revision plan should accompany the letter.
Record the details of when and to whom information was sent on the COIN
service order.
Where necessary, arrange a meeting with the operator to discuss the
conclusions of the assessment including the provision of a revision plan.
Page 41
6.3 Revision Plan
Where the assessment has found that there are significant omissions of information for Schedules
2 and 3 but not requiring a resubmission, the CA may provide the operator with a revision plan to
address the failings. Examples are provided in each of the assessment criteria and guidance packs.
A failure to identify a possible major accident scenario should not by itself be sufficient to warrant
return of the safety report, as measures may exist that provide a level of protection that is not
‘seriously deficient’. The matter could legitimately be raised in a revision plan.
Revision plans should address significant omissions of information and would usually be expected
to have a finite life of no more than 2 years. However, it is acceptable for remaining omissions and
improvements to be included in the next five yearly safety report revision.
6.4 Sharing the safety report assessment records

Following completion of the above components from the conclusions meeting all discipline
specialists should finalise their assessment records so that Part 1 can be forwarded to the
operator. Part 2 should not be shared with the operator These will then help the operator revise
the safety report fully against individual assessors comments in order to produce a more complete
safety report revision at the next five year interval.
Page 42
7. ASSESSMENT FOLLOW UP
Purpose
To provide relevant staff with instruction on the steps necessary to following the conclusion of the
safety report assessment.
7.1 Responsibilities
Assessment Follow Up
Step Responsibility - Action
Ensure the SR Assessment Service Order contains as a minimum, the following
documentation:
a. Final Assessment Plan;
b. Technical Assessment Records from all disciplines that assessed the report;
c. Copies of all correspondence generated during the assessment;
d. Assessment Conclusions Record;
e. Conclusions Letter to the operator;
f. Revision Plan (where one has been produced).
Request the SR Administrator deals with any redundant safety report copies in
accordance with the operator’s instructions.
Respond to any queries and correspondence from the operator in respect of the
assessment conclusions and where necessary, seek advice from the appropriate
assessment team member.
In the case of a Pre-Construction Safety Report, carry forward outstanding issues to
assessment of the Pre-Operation Safety Report.
Where a revision plan has been issued, monitor the operator’s progress in
complying with it.
Where revisions are sent in response to a revision plan, assess them in the same
way as any other safety report content.
Page 43
7.2 Resolving Disagreements
This process to be followed for disagreements that arise between the Assessment Team and
Assessment Manager which cannot be resolved within the team
Step
1 Team Leaders of Assessment Manager and Assessor(s)

Resolve any disagreements that arise out of these activities:
 Assessment Planning and Assessment Conclusions Meeting
Liaise with the Assessment Manager and/or staff member to understand the detail
of the disagreement.
Contact relevant Team Leaders to discuss the disagreement and try to agree a
resolution.
Where the disagreement cannot be resolved then refer it to the Head of the
Operations Unit responsible for regulation of the operator.
2 Head of Operations Unit
For a health and safety issue, the Head of the Operations Unit responsible for
regulation of the operator has authority to decide the outcome.
Resolve any outstanding environmental issue with the appropriate counterpart
within EA, NRW or SEPA.
3 Team Leader of Assessment Manager
Advise the Assessment Manager of the result of the resolution procedure and ask
them to communicate updated assessment conclusions to the operator.
Page 44
8. HOW TO USE THE CRITERIA
Purpose
This section provides guidance on principles and the approach to using the assessment criteria.
The assessment criteria are contained in sections 9 to 14 of this manual and are used by assessors
to examine safety reports submitted under the COMAH regulations, and to reach conclusions on
the extent to which reports meet their purposes under the regulations. Assessment criteria
provide a framework to achieve a consistent and proportionate consideration of matters that may
be examined during assessment. Assessors are not obligated to address every criterion, nor to the
same depth of detail. The criteria reflect the broad nature of the types of establishment which are
covered by COMAH and the range of hazards to be encountered.
8.1 Assessment Criteria Scope

The criteria used for a number of the technical assessment disciplines are common but the
guidance which each assessor follows will provide a focused view of what the particular assessor
should expect the safety report content to provide for their discipline. Clearly an operator may
look to use the same piece of information to assist in making more than one demonstration and
this is acceptable as long as it meets the needs of Schedules 2 and 3 as appropriate.
The criteria are applied by a competent assessor against the relevant content of the safety report.
In this context, the assessor will have a good understanding of the safety report assessment
process, its place within the CA’s overall approach to COMAH regulation and of any stated
benchmarks.
8.2 Meeting the Criteria

a. Criteria will be “met” when all relevant items are included in descriptions and the
necessary supporting information has been provided;
b. Criteria will be “not met” when all relevant items are not included in descriptions or the
necessary supporting information has not been provided;
c. Criteria will be “not relevant” when they are not relevant to the establishment;
d. Criteria will be “previously met” when the previous assessor recorded the criterion as
“met”.
Where the assessment or technical read through of the existing safety report has an assessment
criterion recorded as being met or satisfied, the ‘new’ safety report should not be reassessed
against that criterion unless one or more of the following conditions are met:
 The operator has added to or revised the relevant content; or
 Where the COMAH Regulations 2015 add a new requirement which was not previously
included in the COMAH Regulations 1999 (as amended); or
 The assessor has evidence which contradicts the content of the safety report;
Page 45
In which case it is reasonable for the relevant content to be in scope of assessment.
For assessment of revised safety report information where assessment records have alternatives
to ‘met’ or ‘not met’ e.g. ‘partially met,’ ‘half met,’ ‘mostly met,’etc. then assessors should
comment on the matters identified by the previous assessor recording whether the criterion has
been ‘met’ or not. Proportionality should have been discussed at the Assessment Planning
meeting to guide all assessors.
8.3 Previous Assessment

Further to the above conditions, there may be circumstances where the Assessor has concerns
about specific assessment conclusions drawn from the previous assessment. In the first instance,
the Assessor should raise such concerns in the normal way with their Team Leader. Taking into
account the significance of the issue and wider operational work, the relevant Team Leader will,
where appropriate, approve in principle the additional assessment effort proposed to rectify the
problem. The Assessor and Assessment Manager should discuss the proposal for additional
assessment and agree upon the matters to be communicated to the operator regarding the
change in assessment scope; where agreement cannot be reached the disagreements resolution
procedure should be used.
In advance of the pre-receipt meeting, Discipline specialist assessors should bring deficiencies in
the previous assessment to the attention of the COMAH Intervention Manager.
8.4 Demonstration
Regulation 8 of COMAH Regulations 2015 requires operators to prepare safety reports for the
purposes of making a series of demonstrations. In this context to demonstrate means to ‘show’ or
‘justify’ by the information given which should be taken at face value. It does NOT mean ‘pursue
by extensive in-depth scrutiny’ or ‘exhaustive examination to prove beyond reasonable doubt’
whether the relevant criteria have been met and the demonstrations achieved.
Schedule 3 of the regulations then specifies the type of information to be included in the safety
report. Where this information is satisfactorily provided, the relevant demonstrations under
Regulation 8 would usually have been made. The extent of the information expected to be present
will depend on the type of safety report required by Regulation 9 and 10.
An operator is required by the COMAH regulations to ensure that the data and information
contained within the safety report adequately reflects the conditions in the establishment.
Verification of this can only be achieved by conducting inspections at the establishment which can
then feed back into the safety report assessment, allowing more ‘in-depth scrutiny’ to be
undertaken at inspection rather than assessment. Where evidence is found that undermines the
safety report content this should form part of the contrary evidence referred to in the criterion
assessment (see section 1.3 also).
