VERSION OF THIS DOCUMENT CAN BE FOUND AT http://docs.bpweb.bp.com/dkazspu/component/hssesms
Procedure for Hot Work Naked Flame Page 7 of 16
Engineering shall minimize the need for hot work and provide cost effective
alternatives by careful consideration during the design phase.
It is not permitted unless all other alternatives have been totally exhausted.
When such work is unavoidable it is necessary to ensure that the activity is planned and
activities recorded and approved demonstrating that ALARP requirements have been
met. In meeting ALARP the following shall be considered:
Record Management justification for considering naked flame work, including
consideration of alternatives.
Identify and classify the potential sources of release.
Determine the extent of the probable risk areas.
Carry out a formal risk assessment.
Only when these steps have been completed and with the approval of the Operations
Manager may the Area Authority consider the issue of a Hot Work (Naked Flame)
Permit.
4.2. Clarity
Permit for Hot Work Naked Flame could involve any of the following activities but not
limited to:
Naked flames (welding, flame cutting)
Electrical welding
Electrical induction pre-heating, stress relieving or use of high temperature
thermal calibrators (above 200°C), except in authorised workshops
Use of portable grinders (air or electrically powered)
Abrasive wheels
Use of flare guns
Use of heat shrink blowers in hazardous zones
Use of equipment or work on pipe work or vessels contaminated or potentially
contaminated with pyrophoric scale
Note 1: A Hot Work Naked Flame Permit is not required for operations and/or
maintenance activities involving ignited gas flares or permanently mounted plant using
an enclosed flame (boilers, inert gas generators, etc).

5. RISK ASSESSMENT
Normally work of this nature should be carried out during planned turnarounds when the
plant can be depressurized, drained and made hydrocarbon free.
In circumstances where the OIM/Site Controller/Asset Manager considers that Hot Work
Naked Flame could be safely carried out in a hazardous area and where there is no
other practicable alternative, the following precautions are required:
The Key Risk Issues associated with Hot Work in hazardous areas are the ignition
potential to any local hydrocarbon residues or a leak, which could lead to a localised fire
impact on personnel and potential escalation. Hot work may also require that local fire
detection systems would need to be inhibited.
Any hot work within a zone which is not designated hazardous shall be carried out under
PTW system following appropriate RA and approval process.
5.2. Background
These requirements are based on hazardous area classification for selection of electrical
equipment. They are not identical and care should be taken not to confuse the results,
which may differ significantly (The electrical techniques examines plant in normal
operation while these guidelines are concerned with abnormal operation)
Identification of any item from which flammable material may be released and
then,
The assessment of the extent of the risk area likely to be affected if flammable
material is released
Hot work sites must be prepared in such a manner that fires or explosions cannot result
from the work. To do this, it is essential to take all of the steps necessary to keep
flammable and combustible materials away from hot work ignition sources. However, a
combustible liquid that is confined at a temperature near its flash point becomes highly
flammable when it escapes from confinement.

Procedure for Hot Work Naked Flame Page 9 of 16
Preparing for safe hot work requires knowing sources of flammable and combustible
materials and operating conditions, which could adversely affect conditions at the work
site. The people who prepare the hot work sites also have an obligation to help protect
the people who do the work against other hazards. Such hazards include hot, corrosive
or toxic materials, hot atmospheres, harmful chemicals and unsafe access.
For extent of Designated Zones and their detailed use in different kind of plants (on-
shore / off-shore) refer to API RP 505 and ETP 44-60.
6. WORKPLACE PRECAUTIONS
Where flanges are covered by insulation consideration shall be given to removing the
insulation to enable a satisfactory gas test.
Where it is possible for flammable materials to drain in to open drains, the drains shall
be considered to be high risk unless the drain lines are isolated and the drains flushed
though to remove flammable materials. After a satisfactory gas test such flushed drains
may then be considered to be low risk.

These checklists are to assist the Area Authority of the precautions, which may be
required in completing a Hot Work permit for naked flame work in a hazardous area. A
completed copy of the appropriate checklist is to be attached to the top (performing
authority) copy of the permit and filed with the permit on completion. A new checklist is
required for each permit; it is not permitted to use the same checklist for continuation
permits when the work lasts more than one day.

habitat is in use to raise the alarm in the event of a gas detector activating or
emergency situations
Have an overpressure of 5 to 20mm water gauge (can be monitored by the aid of
slanting pipe fluid manometer)
Have an exterior manometer for read-off of overpressure in the habitat
Be built so as to minimise possible hydrocarbon leakage points in the habitat
Pressurisation shall be by air circulation drawn from a safe zone well away from
any noxious fumes taking account of wind direction and release sources. The
source of air for the inlet duct shall be at least 2m inside a designated safe zone
that has been declared gas free. The exhaust vent shall be ducted, from a point
opposite to the inlet, to a safe, open air zone. Inlet and outlet ducts shall be
protected and either marked with signs or guarded so that obstruction is
prevented. The ducts and air supply hoses shall be clearly marked at both ends
„For Habitat Use – Do Not Remove‟. A gas detector shall be placed at the habitat
inlet for the duration of the task to ensure no ingress of toxic or
flammable/explosive gases.
Radio communication shall be made available to the Entry Attendant whilst the
habitat is in use to raise the alarm in the event of a gas detector activating or
emergency situations
Precautions
Habitats that are constructed for hot work require special precautions to be considered
to mitigate against risk of fire to the habitat itself. Habitats in this case will be constructed
from fire retardant sheeting and additional protection will be required in the form of fire
blankets in the direct vicinity of the hot work area to include floor, and in some cases
walls and ceilings.
Note: It must be remembered that although fire retardant material should be used
throughout, this material in certain circumstances can still support a fire.
It is difficult to specify exactly what specific precaution should be taken as each job will
be different. The following checksheet must be used to identify what precautions have
been put in place; this must be completed for each habitat.
