Hot Work Safety Program
Effective Date: 03/06/2017
Policy Number: 05-90
Section: Safety Operating Procedures
Subject: Safety – Hot Work
1.0 Purpose
This procedure is designed to mitigate or eliminate fire hazards associated with hot
work operations, such as welding, grinding or torch cutting.
2.0 Definitions
2.1 Fire-Safe – A perimeter or immediate area within 35 feet of hot work that has
been cleared of additional fire hazards such as flammables and combustibles, or
otherwise protects flammables or combustibles that cannot be moved with fireresistant shielding.
2.2 Fire Watch – A dedicated team with no other responsibilities other than to watch
for fire in a building or sections of a building, and verify actual fires versus false
alarms to a dedicated person monitoring the fire panel when system components
must be offline. Dedicated fire watches are also required where hot work is being
performed within 35 feet and within 50 feet of permitted open fires outdoors.
2.3 Hot Work – The following activities are considered Hot Work; welding, soldiering,
cutting, brazing, grinding, use of asphalt / tar kettle(s), or other work that might
create sufficient heat or spark, which could start a fire.
3.0 Scope
This program applies to all persons, including contractors, and Arkansas State
University units conducting Hot Work, as defined in the terms, on University owned or
leased property. NOTE: Areas permanently established and arranged to conduct
ongoing hot work are exempt.
3.1 Hot work shall not be conducted in any area other than those specifically
intended and designed for conducting said work unless the area has been
inspected and a Hot Work Permit (See section 4) has been issued to the
person(s) who will be conducting the actual work.
3.2 Only approved apparatus such as torches, regulators, pressure reducing valves,
acetylene generators, machines, manifolds, cables and hoses in good repair will
be used.
a. Manufacturer’s procedures/recommendations will be followed with respect to
the sequence of operations for welding, cutting and grinding equipment.
b. Only acetylene tanks that have been in the vertical position for a minimum of
2 hours will be used.
c. Torches will be pointed away from people and combustible materials when
lighting.
d. Torches will be lit with a friction lighter or stationary pilot flame. Torches will
not be lit from hot metal.
e. When equipment is not going to be used for periods of 30 minutes or more
or when left unattended the equipment will be shut off.
f. Only people who are trained and proficient will conduct hot work. Trainees
may perform work only when their trainer or supervisor is in the immediate
area.
3.3 A Hot Work Permit form will be completed prior to start of hot work. The Hot
Work Permit form can be found online: https://astate.campusoptics.com/pr/hotwork
By completing this form, employees performing hot work confirm and attest that
the following has been completed:
a. Inspections of the work site have been completed
b. The area is deemed fire safe and/or the necessary instructions to ensure
such safety is provided.
3.4 The online permit form will send an email to the submitter, the Work Order
Center and the Life Safety Systems Coordinator, including all safety precautions
to be taken and the designated work period timeframe.
a. Permits must be available at the work site. The email returned to the
submitter can be used for this purpose.
b. If the email is not available on the employee’s mobile device, arrangements
should be made with the Work Order Center, supervisor or other A-State
employee with access to a printer, in order to print and deliver the permit to
the work site.
3.5 If in the inspector’s opinion the area is not safe, work will postponed until such
time as the area is made safe.
3.6 In situations where delaying work to complete the form would allow, or increase
damage to University property or critical research project, the individual to
performing the hot work shall ensure the area is fire safe then proceed.
3.7 Open flames are prohibited in University buildings. Open flame devices and
materials include but are not limited to; candles, oil burning lamps and incense.
Exceptions include:
a. Laboratories where flames or burners are used with the proper safety
precautions in place.
b. Shops where hot work is performed in a fire-safe environment.
3.8 Permits for small projects and spot work will generally be issued for a period of
twelve hours only. However, in areas where the work will be ongoing for an
extended period of time, permits can be issued for periods not to exceed
seventy-two hours as long as the work or situational factors do not change.
3.9 Permits for closed construction sites with restricted public access can be issued
for the duration of the project, provided inspections are conducted to ensure the
area where hot work is performed is fire safe. Inspections must be documented
and records must be retained on the job site.
4.0 Fire Protection Equipment
4.1 Vertical storage may not be stacked within 18 inches of sprinkler heads.
4.2 Tampering with or attempting to perform unauthorized maintenance on fire

4.4 Employees must not use fire extinguishers without prior knowledge of their
proper use.
a. Learn the basics of fire extinguisher use on the Safety & Emergency
Management website: http://www.astate.edu/a/ehs/emergencyservices/files/fire-safety.pdf
b. The Safety Office will determine the appropriate staff to receive hands-on
