Industrial Hygiene Baseline Hazard Assessments

Published Date: 06/13/2017 Effective Date: 06/13/2017

1.0 PURPOSE

This procedure provides instructions to Industrial Hygienists (IH) or other Safety and Health (S&H)
professionals conducting Industrial Hygiene Baseline Hazards Assessments (IHBHAs) for Mission Support
Contract (MSC) operations or work areas.

IHBHAs are intended to:

1. Systematically identify and evaluate recognized potential worker health risks and other hazards
with adverse exposure potential as deemed necessary by the project IH.

2. Allow for objective prioritization for future evaluation, monitoring, or sampling activities in
effort to make efficient use of Mission Support Alliance (MSA) resources.

3. Serve as a basis for analysis to determine the source and nature of the IH hazards and to
establish appropriate hazard control measures documented using one or a combination of
hazard analysis documentation categories. Chemical groupings are used to establish the basis
for the chemical use attachment (CUA).

4. Assist in communicating information from the IH to line management and affected employees
regarding recognized chemical, physical, and biological exposure hazards and controls during
the work planning process.

5. Identify and characterize similar exposure groups (SEGs) in a work area.

NOTE: The supporting information (e.g. calculations, field observation, or similar sampling data) used to
justify the determination for or against sampling as recorded in the IHBHA may also serve as
documentation of the exposure evaluation.

The implementation of this procedure provides information to enhance the planning and job hazard
analysis (JHA) processes (see MSC-PRO-WP-079, Job Hazard Analysis) and the Employee Job Task
Analysis (EJTA) process (see MSC-PRO-WP-11058, Occupational Medical Qualification and Monitoring
using EJTA) by:

1. Providing an overview of the IH hazards for an operation or work area.

2. Defining and characterizing those IH hazards.

3. Providing a consolidated list of the IH assessment needs.

This document partially implements the ISMS Core Function #2, Identify and Analyze Hazards.

NOTE: Employees may print off this document for reference purposes but are responsible to check MSA PS to
ensure the most current version is used to prevent unintended use of obsolete versions.

2.0 SCOPE

This procedure applies to MSC operations or work areas where worker exposures to chemical, physical,
or biological hazards warrant identification, evaluation, or control. This includes, but is not limited to,
evaluation of compliance with OELs at levels of occupational significance and comparison of other
occupational exposures to best practice guidelines issued by standards bodies or professional
organizations.

This procedure is not intended to address:

 Radiological Control Manual; See MSC-OTHER-RC-5173

 Biological Hazards (Including Bloodborne Pathogens); See MSC-PRO-WP-45039

 Ergonomics; See MSC-RD-WP-8471

 Heat Stress Control; See MSC-PRO-WP-121

 Bulk or wipe samples taken for identification or investigational purposes only;

 Indoor air quality (IAQ) investigations where there is no direct correlation to an OEL or other
quantifiable risk criteria.

In addition, operations and work areas specifically included in a MSC subcontractor hazard analysis per
MSC-PRO-WP-079, APPENDIX C Job Safety Analysis (JSA) where sampling requirements, IH hazard
analysis, or control measures are communicated are not required to perform or document IHBHAs.

Although this procedure establishes the basis for planning and prioritizing quantitative and qualitative
exposure assessment activities, Initial Hazard Analysis Screening Criteria as found in MSC-PRO-WP-079,
APPENDIX B shall be utilized for implementation of hazard controls including IH monitoring activities
when used for hazard control.

3.0 IMPLEMENTATION

This procedure is effective on publication.

Pre-existing IHBHAs will be updated with any new procedural requirements during their next scheduled
revision.

4.0 REQUIREMENTS

This procedure implements the requirements specified in 10 CFR 851, Worker Safety and Health
Program, sections 851.21 & 10 CFR 851 Appendix-A, Section 6.

IHs shall utilize recognized exposure assessment and testing methodologies and accredited and certified
laboratories. These specific methodologies are referenced in the sample plan and analytical laboratory

requests found in Site Wide Industrial Hygiene Database (SWIHD) as described in MSC-PRO-WP-409,
Industrial Hygiene Monitoring, Reporting and Records Management.

5.0 PROCESS

5.1 Initial Assessment

The steps listed below are typical components of an initial IHBHA. However, because each operation or
work area is different, these steps can be rearranged as necessary.
Actionee Step Action

MSA S&H 1. Perform a review of available documentation. This may include:

professional
 Past IHBHA’s
 Hazard Analysis
 Past monitoring data
 Hazard Communication (HAZCOM) plans
 Material Safety Data Sheets (MSDS)
 Chemical and Carcinogen Inventories
 Other documentation if available

2. Perform interviews of project management, supervision, or lead workers.

This step can provide an opportunity to ask questions relating to the

information that was encountered during the document reviews and may
provide additional information that will provide insight into the work processes
that will be encountered.

3. Perform a walkthrough inspection of the work area or the operations

performed by the SEG being assessed. Identify the hazards which present a
potential for occupational exposure to chemical, physical, or biological hazards.

Not all operations with a potential chemical, physical, or biological hazard can
or will be identified during one walkthrough. Some operations may be
performed on an infrequent basis and will only be identified through employee
interviews or multiple walkthroughs.

NOTE: Prior to entering a work area you may be required to review and sign the
applicable hazard analysis or be accompanied by an escort.

4. Perform employee interviews.

NOTE: Employees may print off this document for reference purposes but are responsible to check MSA PS to
ensure the most current version is used to prevent unintended use of obsolete versions.

5.2 Hazard Evaluation, Exposure Assessment Prioritization, and Documentation

Actionee Step Action

MSA S&H 1. Document the IHBHA report, including the use of Field Evaluation (FEV) Table
professional (see Appendix C), per the following guidelines1:

a) A completed IHBHA will consist of the following items:

 A report or text regarding the work being performed including
information about:
o The tasks or area being evaluated,
o Hazard Description including:
 Summary of the work where the hazard is
encountered
 Current controls used
 Summary of past monitoring results
 Information related to additional assessment
needs
b) A Completed FEV Table
c) Include SWIHD references of the IH Survey Numbers for the past 2
years.

NOTE: The IHBHA is intended to assist in systematically characterizing

the potential for occupational exposure and serving as the basis for
recommending hazard control measures. However, pertinent
information found in the IHBHA should be flowed-down into the job
hazard analysis documents for the managers, supervisors, and craft
employees who may not be interested in the full technical basis for the
conclusions that were reached in the IHBHA.

Be aware of the needs of intended audience when completing these

documents. For ease in communicating the conclusions of the IHBHA
assessment, it may be more appropriate to retain some technical
documentation as a separate attachment from the main IHBHA.

1 This exposure assessment strategy is based in part on the American Industrial Hygiene Association's (AIHA)
publication titled “A Strategy for Assessing and Managing Occupational Exposures”.

NOTE: Employees may print off this document for reference purposes but are responsible to check MSA PS to

Actionee Step Action

2. List each hazard that is within the scope of this procedure, namely chemical
groups (by type or category), physical, or biological hazards on the FEV table
(see Appendix C). Suggested information to include:

Location Source Hazard

Description Hazard Control

Work Process or Activity Exposure Rating

SEG’s where applicable Qualitative Exposure Rating

Health Effect Rating Priority Rating

Past Sample Data (Survey

Numbers)

3. Evaluate each hazard using the ratings listed in Table 1-3 and Industrial
Hygiene hazard evaluation techniques and record the rating in the FEV table.

4. Assign a Qualitative Exposure Assessment Rating by multiplying the numbers

obtained from Table 1 and Table 2 and record the rating in the FEV table.

NOTE: Employees may print off this document for reference purposes but are responsible to check MSA PS to
ensure the most current version is used to prevent unintended use of obsolete versions.

Actionee Step Action

5. Assign a Priority Rating based off the Exposure Assessment Rating using the
following guidelines:

11-16 High Priority

5-10 Medium Priority
1-4 Low Priority

 DOE, OSHA, or company specific monitoring requirements

elevate the Priority Rating to High Priority.
 Hazards without prior exposure monitoring data where
respiratory protection is used for personal protective purposes
should be assigned a High Priority status.
 For exposure scenarios with uncertainty due to lack of
information or other factors the Priority Rating should be
elevated one category.
 For scenarios where monitoring results indicate employee
exposures are within guidance limits the Priority Rating may be
reduced according to the IHs professional judgment.

5.3 Issuing IHBHA’s

Actionee Step Action

MSA S&H 1. Each IHBHA document shall be updated as industrial hygiene hazards change
professional for the exposure group. Additionally, when the craft specific hazard analysis
(CSHA) and CUA documents are updated, the IHBHA shall also be updated if
necessary. When the FEV Table identifies a MEDIUM or HIGH priority rating
where the controls in place at the time of the assessment do not provide
adequate protection to the worker to minimize occupational illness or injury,
the documented hazard analysis shall be updated with additional controls for
exposure mitigation. When possible, reference specific hazard analysis
document(s) within the summary information.

NOTE: Employees may print off this document for reference purposes but are responsible to check MSA PS to
ensure the most current version is used to prevent unintended use of obsolete versions.

Actionee Step Action

New work processes in industrial areas do not require immediate revision of

the IHBHA, provided that an adequate hazard analysis is performed and
documented. However, that analysis and documentation must be included in
the next scheduled revision of the IHBHA.

NOTE: This requirement refers to establishing a date to review the accuracy of

the IHBHA report/text, FEV table, and the associated controls or
recommendations with the intent that new information based off of the
completion of the past recommendations is added to the IHBHA.

It is not intended to imply that all past monitoring must be renewed or redone.
However, the need for renewed monitoring should be assessed at that time.

2. Inform project management, line management, and employees of results of the

IHBHA as part of the periodic CSHA hazard analysis review and
acknowledgement. At a minimum this should include the following content:

 IHBHA Report/Text Summary.

 FEV Table

 Include references of the IH Survey Numbers for the past 2 years

MSA S&H 3. The method of retaining IHBHA documents is to utilize SWIHD as described in
professional MSC-PRO-WP-409, Industrial Hygiene Monitoring, Reporting and Records
Management.

Publish the IHBHA utilizing the SWIHD interface utilizing the following:
 Under the “Baseline” tab within SWIHD, obtain a unique number to identify
the BHA.
 While in the Baseline tab, you may use the “Help” link to see a “screen shot”
of step-by-step process in uploading and creating the BHA report.

NOTE 1: OUO documents should NOT be uploaded as an attachment to the BHA

report in SWIHD. However, IH survey reports containing OUO information may
be linked to the BHA in SWIHD and are properly protected.

 When you complete the BHA report, it will be automatically converted to a

record and placed into IDMS.

 While in the “Post BL” tab, you may use the “Help” link to see a “screen
shot” of step-by-step process to attach IH survey records to the BHA report
after it has been created as a record.

NOTE: Employees may print off this document for reference purposes but are responsible to check MSA PS to
ensure the most current version is used to prevent unintended use of obsolete versions.

NOTE 2: IH surveys referenced within the record BHA are considered “historical”
records once the BHA has been sent to IDMS. Additional IH surveys linked to the
BHA will be incorporated into the next revision of the BHA record.

APPENDIX A Glossary

Term Definition

Similar exposure A group of employees whose exposures to chemical substances or physical

group (SEG) hazards have been determined to be similar enough that monitoring the
exposures of randomly selected workers in the group provides data useful for
predicting the exposures or exposure profiles of the remaining workers. A SEG is
also defined as a group of individuals who perform the same jobs or tasks and
who have similar exposures to an individual hazardous agent.

Operation A task or group of tasks performed by an SEG that may result in personal
exposures as defined in Section 2.0 Scope, of this document.

Work Area A building, tent, lay down yard, or other structure where work is performed that
may result in personal exposures as defined in Section 2.0 Scope, of this
document.
