Welding – Hot Work

What is hot work?

Working with ignition sources near flammable materials is referred to as “hot work.” Welding and cutting are examples of hot work. Fires are often the result of the “quick five minute” job in areas not intended for welding or cutting. Getting a hot work permit before performing hot work is just one of steps involved in a hot work management program that helps to reduce the risk of starting a fire by welding or cutting in areas where there are flammable or combustible materials.
