HOT WORK PROCEDURE
Environmental Health and Safety
HOT WORK PERMIT PROCEDURE
PURPOSE
All hot work creates conditions, which increase the probability for fire-related injury or
property loss. Hot work includes but is not limited to brazing, cutting, grinding, soldering,
and welding. Each type of hot work presents specific hazards depending on the methods
used, the materials used, and the environment involved.
The objective of this Hot Work Program is to reduce the potential for injury, fire and/or
explosion resulting from the performance of the work. The procedures contained in this
Program are applicable to all employees, property managers and outside contractors working
at Forevision construction. Environmental Health and Safety (EHS) provides oversight for this
Program.
The Hot Work Program prohibits Hot Work activities in/on Airport Parking Areas, until specific
safety precautions are taken, and the work has been properly authorized. Hot Work locations
are described as either a temporary Hot Work Site by the issuance of an approved Hot Work
Permit; or a designated Hot Work Site that is maintained in such a way that would allow Hot
.Work to be performed without the issuance of a Hot Work Permit
Sprinkler systems must not be disabled, and fire alarm systems must be operational during hot
work. Smoke detectors in the vicinity of hot work should be disabled to prevent inadvertent
activation, and the system must be immediately restored to full operation after work is
completed.
RESPONSIBILITY
Supervisors are responsible for ensuring that hot work is performed safely. The supervisor
shall ensure that the authorized permit writer is properly trained and understands the
hazards associated with hot work.
It is the responsibility of all involved to ensure that the permit conditions are adhered to and
the work is done safely.
DEFINITIONS
A. Fire Watch: A person trained in the use of fire extinguishers that is designated to observe the
area surrounding the hot work and is prepared to extinguish any fire that may be ignited. A
properly maintained fire extinguisher of the appropriate hazard class, preferably a 10-pound
dry chemical ABC is required in any area where appreciable combustible or flammable
materials are within 35 feet of the hot work.
B. Hot Work: Any temporary or permanent operation involving open flames or producing heat
.and/or sparks including but not limited to brazing, cutting, grinding, soldering and welding
C. Hot Work Permit: A written checklist of procedures to be implemented before performing
hot work in a hot work hazard area. Signing the completed permit is done to ensure that the
proposed work has been reviewed for all applicable safety considerations. Permitted hot
work shall be done in accordance with the details on the permit. If conditions change, the
permit must be modified or reissued by the hot work’s responsible person. Completed
permits shall be maintained in the EHS office for 1 year.
D. Restricted Area: Any space within thirty-five (35) feet of equipment where a flammable
or combustible substance is or may be stored, handled, used, processed or in
the atmosphere. Does not include designated safe welding areas (e.g. shops and fabrication a
reas)
E. Responsible Person: A person with training, experience and judgment to oversee hot work
operations and who has the authority to direct changes or stop the work if necessary.
Responsible Person reviews the site(s) prior to issuing permits as part of the hot work permit
program and following up as the job progresses. Responsible person shall determine the
hazards present or likely to be present at the work location and the precautions necessary to
prevent an incident.
TRAINING
All Fore-Vision Construction employees who may be affected by hot work, who conduct
hot work activities and those authorized to issue hot work permits must receive hot work
and fire prevention initial and annual training. Fire watcher staff may be instructed of their
responsibilities prior to commencing the hot work activity
PROCEDURE
A. The authorized permit writer shall initiate the permit along with the individual responsible
for doing the work and make a joint inspection of the work area. The inspection shall be
made as soon as practical, but no more than one (1) hour before starting the hot work.
B. The Hot Work Permit needs to have two (2) copies made. One copy should be kept by

permit is suspended for any reason, it must be re-issued. No permit is valid for more than
one (1) shift. If work is interrupted for more than one (1) hour, it will be necessary for
the equipment and area to be re-checked. If the original permit writer goes off duty or
if the responsibility for the hot work activity is given to another person,
conditions must be re-checked, and a new permit issued, or the original permit re-
authorized.
D. The date and time the work is to begin, and expiration shall be clearly shown on the permit.
E. Site preparation, safety equipment, and work procedures shall be checked giving enough
detail to any precautions need to be listed on the permit and communicated to everyone
involved in the project.
F. After the inspection has been completed and a safe work environment exists, the authorizer
of permit will sign the permit for work to commence.
G. Prior to the work beginning the individual performing the Fire Watch will sign, date and
record the time when the Fire Watch began.

record the time of the conclusion of the Fire Watch.
I. The completed permit is returned to the area supervisor and the original is forwarded to
EHS.
WHEN PERMITS ARE REQUIRED
Hot Work Permit shall be prepared when hot work is done in a restricted area. A permit shall
be written for the following activities:
When using devices that may produce sparks, flame or heat in an area where flammable
vapors may be present. Examples include: portable grinders, portable compressors, abrasive
wheels, arc welders, gas welding equipment, cutting torches, soldering, electric drills, heat
guns and sand blasting.
GENERAL HOT WORK PRECAUTIONS
A. Conditions of general housekeeping in the area must be checked. All movable fire hazards
shall be removed or controlled within a thirty-five (35) foot radius of the work to be done.
B. A minimum of one (1) ten (10) pound fire extinguisher available either dry chemical ABC
or Halotron for instant use shall be at each job site. Employees must be trained in the use of
fire extinguishers and firefighting control techniques. They shall have an adequate

work will be performed.
C. All work must be within sight of the assigned fire watch.
D. Required personal protective equipment (PPE) must be worn.
FIRE WATCH
A. A Fire watch is required for any job requiring a permit and whenever welding or cutting is
performed in locations where any of the following conditions exist:
1. Appreciable combustible materials, ignitable by sparks or slag, are closer than thirty-five
(35) feet to the point of operation;
2. Wall or floor openings within a thirty-five (35) feet radius expose combustible materials
in adjacent areas including concealed spaces in walls or floors;
3. Combustible materials are adjacent to the opposite side of metal partitions, walls,
ceilings or roofs and are likely to be ignited by conduction or radiation.
B. Personnel performing a fire watch:
1. Must be trained in the use of fire extinguishing equipment.
2. Shall be familiar with facilities for sounding an alarm in the event of a fire. Shall watch
for fires in all exposed areas, sound the alarm if necessary, and try to extinguish them
only when obviously within the capability of the equipment available.
3. Shall have no other primary function.
4. Shall be maintained for thirty (30) minutes after completion of the hot work and during
breaks and lunches to detect smoldering fires. When combustible construction, fire loads
and occupancy factors exist.
