Section 3: Hot Work Procedures
- Hot Work Permit Forms: The WNC Hot Work Permit form [see Appendix A).
- Prior To Hot Work: Several tasks must be performed before hot work begins. These include, but are not
- Inspecting the hot work area to identify any fire hazards.
- Remove all flammable or combustible materials within a thirty five-foot radius of the hot work.
- Properly shield combustibles that cannot be removed from the area with non-combustible blankets or other non-combustible materials.
- Seal all cracks and openings through which hot sparks or slag may enter. As an alternate means, a fire resistant shield may be used to block the openings.
- Sweep floor of all loose combustible debris.
- Placing non-combustible or flame resistant screens so as to protect personnel in adjacent work areas from heat, flames, radiant energy and welding splatter.
- Protect conveyer systems that may carry sparks of slag to other parts of the building.
- Mark the area so as to warn nearby personnel of the danger.
- Cover sprinkler heads directly above the hot work area with wet rags or other non-combustible materials so they will not be triggered during the work.
- Cover smoke detectors located in close proximity of the work area
- Identify conditions that if changed could increase the risk of fire.
- During Hot Work: During the hot work there are other precautions that must be taken:
- Appropriate fire extinguishing equipment shall be maintained in close proximity to the hot work for its entire duration, plus 30 minutes.
- Combustible floors shall be kept wet during the hot work.
