Purpose
This procedure will provide the knowledge and equipment required to minimize the identified
workplace hazards associated with Hot Work.
Legislation
Hot Work
(1) Where a flammable substance is or may be present, an employer or contractor shall
ensure that no hot work is performed until:
(a) suitable tests have been conducted that;
(i) indicate whether the atmosphere contains a flammable substance in a quantity
sufficient to create an explosive atmosphere; and
(ii) confirm that the work may be safely performed; and
(b) the work procedures developed pursuant to clause 363(1)(b) have been
implemented to ensure continuous safe performance of the work.
(2) While hot work is being performed, an employer or contractor shall conduct tests
described in clause (1)(a) at intervals appropriate to the work being performed and
record the results.
(3) An employer or contractor shall not require or permit any hot work to be performed in the
vicinity of a material that may constitute a fire hazard until suitable steps have been
taken to reduce the risk of fire.
(4) An employer or contractor shall ensure that a container or piping that contains or has
contained a flammable substance is purged using an effective method to remove the
flammable substance from the container or piping before any hot work is begun on that
container or piping.
(5) An employer or contractor shall not require or permit any welding or cutting of metal that
has been cleaned with a flammable or combustible liquid until the metal has thoroughly
dried.
Definitions
Competent means possessing knowledge, experience and training to perform a specific duty.
Engineering controls help reduce exposure to potential hazards either by isolating or removing
the hazard from the work environment. Engineering controls include mechanical ventilation and
process enclosure, and are preferred to other control measures such as the use of personal
protective equipment.
Gas is a material without a specific shape or volume. Gases tend to occupy an entire space
uniformly at normal room pressure and temperature. The terms vapour and fume are sometimes
confused with gas.
Hot Work means work that produces arcs, sparks, flames or other sources of ignition.
Supervisor means a person who is authorized by the University of Regina to oversee or direct
the work of employees or students.
Train means to give information and explanation to an employee with respect to a particular
subject matter and require a practical demonstration that the employee has acquired knowledge
or skill related to the subject matter.
Vapour is the gaseous form of a material which is normally solid or liquid at room temperature
and pressure. Evaporation is the process by which a liquid is changed into a vapour.
Responsibilities
5. Employees will:
5.1 work in accordance with the University’s Hot Work procedures.
5.2 not perform Hot Work until a Hot Work Permit is obtained.
5.3 complete an Incident Report and notify their supervisor if during Hot Work an injury,
suspected occupational exposure, property damage or occurrence which may have
resulted in injury, exposure or damage if conditions had been different occurs.
Prior to performing any hot work, alternative methods of conducting the work should be
considered with a view to decreasing the risk of loss due to fire at the University.
If reasonably possible, the Hot Work should be conducted in a fixed area designated for doing
Hot Work. Designated areas could include non-combustible buildings or within secured non-
combustible barriers. All combustibles within the work area should be removed and
extinguishers or other fire protection provided.
Hot Work shall not be permitted in the following areas until the conditions prohibiting Hot Work
have been modified:
In the presence of explosive atmospheres, or in situations where explosive atmospheres
may develop inside contaminated or improperly prepared tanks or equipment which
previously contained flammable liquids.
In areas with an accumulation of combustible debris, dust, lint and oily deposits.
In areas near the storage of exposed, readily ignitable materials such as combustibles.
On a container such as a barrel, drum or tank that contained materials that will emit toxic
fumes when heated.
In a confined space, until the space has been inspected and determined to be safe.
Refer to the Confined Space Procedures of the Safety Program.
Fires caused by hot work significantly affect our ability to do business. Employees and
contractors partner with the University in preventing losses. Avoiding hot work by using
alternative methods where possible is required. If hot work cannot be avoided, the procedures
must be strictly followed and the permit posted. Contractors must sign a legal contract
applicable to work they perform for the University.
Contractors
The University Project Manager or Facilities Managers will require you to follow our procedures
for hot work. If appropriate, the supervisor will introduce you to other workers in the area to
discuss unique work conditions you should be aware of before your work begins. The
University’s hot work rules must be followed. Violations will result in terminating the work.
A hot work permit is required for any temporary operation producing open flames or sparks. This
includes brazing, cutting, grinding, soldering*, pipe thawing, torch-applied roofing and welding.
1. If there is a practical and safer way to do the job without hot work, that method must be
used.
2. No hot work is permitted without authorization, in the form of a signed hot work permit. This
permit will be valid for a maximum of one shift, or eight hours, whichever is shorter.
3. Specific fire fighting equipment and protection material will be required at the hot work site
before any work can be started.
4. No hot work is permitted without a designated trained person present as the fire watch. This
fire watch will have total control over the hot work area for fire prevention. If unsafe
conditions are observed, the hot work operation will be stopped until the hazard is
neutralized or eliminated.
5. The person performing the hot work will verify that all hot work equipment is in proper
working order and in a firesafe condition. An inspection of the equipment will be conducted
by the firesafety supervisor before the hot work permit is issued. Any unsafe equipment will
be removed from service.
