Hot work
Hot work is work that produces sparks or
requires an open flame or another source
of heat to complete and therefore poses a
risk of fire. Examples of hot work include
electrical welding and gas welding, gas
soldering, use of hot air blower, flame
cutting, metal grinding and abrasive cutting.
The hot work permit issuer, hot work
guard and hot work operator must have
a valid hot work card.
The extinguishing equipment and protec-
tion that must be made available at a
temporary hot work is defined in the hot
work permit and must include at least:
two hand extinguishers of class 43A
183BC, one of which can be replaced
with two hand extinguishers of class 27A
144BC or a hose reel.
Hot work must always be performed at a
permanent hot work site when possible.
Generally at permanent hot work sites
there is no need for hot work permit and
hot work guard.
Hot work guarding at a temporary hot
work site should be performed throughout
the duration of the work, including
breaks. Guarding after hot work is
completed must continue for the period
of time defined in the hot work permit,
not less than one hour.

relating to fire safety, contact fire department
or your supervisor.
