Hot work permit program

Hot work is defined as any operation that involves or generates open flames, sparks or heat that could become a fire hazard. Examples include cutting, welding, grinding, torch-applied roof covers, soldering, etc. A permit should be completed when conducting hot work operations outside a permanent designated area.

The permit should be completed by a person in charge, such as the supervisor, who should:

  • Establish fire watch precautions
  • Inspect the worksite and check the precaution before signing the permit authorizing the work and allowing the operation to proceed.

A continuous fire watch while the operation is active and for at least 30 minutes after work has ceased should be provided. The fire watch should include the immediate work area and the floor above and below. The fire watch should also be active if the work is temporarily stopped for a break or any other reason. Fire extinguishers and/or a charged small hose must be available in the fire watch areas. Fire watch person(s) must be trained to use fire extinguisher or hose and to sound the fire alarm.
