Cutting and welding operations (referred to as hot work) are commonly associated with renovation and construction activities. Potential health, safety, and property hazards result from the fumes, gases, sparks, hot metal and radiant energy produced during hot work. Hot work equipment, which may produce high voltages or utilize compressed gases, also requires special awareness and training on the part of the worker to be used safely. However, the hazards associated with hot work can be reduced through the implementation of effective control programs.

Hot work permits should be used where cutting or welding is performed. Hot work permits can help minimize the risk of fire during cutting and welding activities by serving as a checklist for operators and those performing fire watch duties, and should include the following:

1. Have alarm systems been disabled prior to beginning work? Has Public Safety been notified at extension 258-3135?

2. Has equipment been inspected and found to be serviceable prior to use?

3. Are sprinklers in service, where provided?

4. Have flammable liquids been removed from work area?

5. Have combustible or hazardous materials been relocated at least 35 feet from the operation?

6. Have combustible materials that cannot be removed been covered with fire-resistive tarpaulins?

7. Have floor and wall openings within 35 feet of the operation been tightly covered?

8. Have screens or shields been erected to protect pedestrians from the welder’s arc?

9. Has the atmosphere been tested for presence of flammable gases or vapors?

10. Do all workers have personal protective equipment (PPE) appropriate for their tasks?

11. Are ample fire extinguishers available?

12. Has a fire watch been provided during work, breaks, and for at least 30 minutes after work is complete?

13. Have alarm systems been reactivated after work is complete? Has Public Safety been notified at extension 258-3135?
