6900 Appendix T1 Fire Protection: Hot Work Permit –
Instructions |
||
|
|||
Any work activity that requires an open flame (greater than a BIC lighter); welding or brazing activities; and/or spark producing grinding or cutting operations are restricted at Jefferson Lab and require a Hot Work Permit unless they are performed in a designated area established by an Operational Safety Procedure (OSP). |
1.0
Purpose
Jefferson Lab requires a Hot Work Permit (HWP) to identify
hazard issues and communicate activities performed to mitigate environmental,
health, and safety issues resulting from hot work operations. This appendix
provides instruction for completing, authorizing, and approving a HWP at Jefferson Lab. The issuance of a HWP demonstrates that specific actions have
been taken to reduce the risk for a defined time period.
2.0
Scope
A HWP
authorizes hot work operations to be performed outside a designated area established
by an Operational
Safety Procedure (OSP) including Tungsten Inert Gas/Metal Inert Gas (TIG/MIG) welding.
Electron beam welding and vacuum
brazing are excluded from this requirement.
Exception: Pedestal and stationary
grinders mounted in permanent machine shop areas do not require a HWP when
work activities are controlled through an OSP. See ES&H Manual Chapter
6121 Machine Tools. |
All
HWPs expire on the last day of the month they are generated, regardless of the
actual date issued (ex: HWP issued January 1 expires January 31, HWP issued
January 30 expires January 31).
These
instructions are performed in coordination with ES&H Manual Chapter 6900
Fire Protection Program.

4.1
Introduction
·
Start Date: Date hot work
will commence.

“Yes” or “No” as appropriate.
o A fire watch is required if the hot
work is performed in a building/area where any of the following conditions
exist:
§ Combustible materials in building
construction or contents are closer than 35ft (11 m) from the point of
operation.
§ Combustible materials are more than
35ft (11 m) away but are easily ignited by sparks.
§ Wall or floor openings within 35ft
(11 m) radius expose combustible materials in adjacent areas, including
concealed spaces in walls or floors, or if people are in these adjacent areas.
§
Combustible materials
are adjacent to the opposite side of partitions, walls, ceilings, or roofs and
are likely to be ignited.
§
Oxy–fuel gas welding
and cutting operations in an underground structure.
§
Outdoors within 35ft
(11 m) of vehicles, mulched areas, or vegetation.
§
Operations are performed
on the roof of a building; or at any elevated level.
o More than one Fire Watch is required if combustible materials could be ignited and cannot be directly observed by a single Fire Watch.
·
Fire Watch Name: Print
Name(s) of Fire Watch designee.
·
SAF 108, or equivalent, Date Last Acquired: Access the designated Fire Watch’s Skills
Requirements List (SRL) note the date when Fire
Safety Training was “Last Acquired” and current “Status.”
4.2
Inspection Checklist: Identify flammable/combustible materials, fire hazards, or
hazardous processes present or likely to be present in a hot work area,
including areas below and adjacent to the hot work area.
a.
Verify that the sprinkler and fire alarm systems in
the area are fully operational. Contact
Facilities Management (ext. 7400) for information or assistance.
b. Verify that the hot work equipment to be used is in good repair and satisfactory operating condition. Do not commence operations until it is.
c.
Relocate all flammable and combustibles at least 35ft
(11m) in all directions from the proposed work area and the following criteria
shall be met.
1.
If relocating is impractical, combustibles are to be
protected by a listed or approved welding curtain, welding blanket, welding
pad, or equivalent.
2.
To prevent the entrance of sparks, the edges of covers
at the floor shall be tight, including at the point at which several covers
overlap where a large pile is being protected.
3.
In instances where the scope of work and the tools
used to conduct hot work result in possible travel of slag, sparks, spatter or
similar mobile sources of ignition farther than 35’ (11m), the Fire Marshal shall
be permitted to extend the distances areas addressed in Section 4.1 – Is a Fire
Watch required.
4.
In instances where the scope of work and tools used to
conduct hot work are known to be incapable of generating slag, sparks, spatter
or similar mobile sources of ignition capable of leaving the immediate area of
the applied hot work, the Fire Marshal shall be permitted to do the following:
§ Reduce the distances and areas
addressed in 4.1 to distances and areas that he or she considers fire safety
for the intended operation (i.e., TIG welding with ten foot clearance from
combustibles).
§ Describe those distances and areas
on the hot work permit.
5.
Based on local conditions, the Fire Marshal shall
determine the length of the period for which the hot work permit is valid.
d.
Render all potentially affected hazardous process
“safe.”
§ Note each hazard (e.g.: cryogenics, pneumatics, electrical,
compressed gas systems)
§ The control used for each (e.g. lockout/tagout).
4.3
Considerations (additional work control
documents may be required to mitigate additional hazards identified)
·
Notify potentially
affected persons.
o
Brief any affected
workers of the heat and smoke alarm status.
·
Ensure all workers in
the area have the proper personal protective
equipment (PPE) including suitable protected against heat, sparks and slag (include the “Hot Work Operator” and “Fire Watch”).

Evaluate the
ventilation system (if in doubt, refer to ES&H Manual Chapter 6630
Appendix T1 Engineering Controls – Local and Portable Exhaust Systems for guidance before beginning the
work)

that may impact the planned work (e.g. Pressurized Systems, Radioactive
Materials,
Hazardous
Chemicals)
4.4
