11. FIRE PROTECTION 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. For more information regarding any matters relating to fire safety, contact fire department or your supervisor. 52
