Fire watch must be in place during and for at least <u>a half hour </u>after hot work, including any breaks.
Any task requiring an ignition source close to combustible materials is referred to as hot work. Hot work includes processes including cutting, soldering, and welding.
Fires frequently occur when "quick five minute jobs" are attempted in locations not intended for welding or cutting. Obtaining a hot work permit is one of the steps of a hot work management program that helps reduce the risk of starting a fire by performing hot work in locations where there are flammable or combustible materials.
The 2014 edition of NFPA (National Fire Protection Association) Standard 51B, "Fire Protection in the Use of Cutting and Welding Processes," is the foundation for many of the industry's current fire prevention strategies.
