Hot work is any construction or maintenance procedure which requires heat or open flame to complete.
Hot work continues to be a leading ignition source of fires and explosions in construction sites which have resulted in millions of dollars in losses. The flame from an oxyacetylene cutting torch can reach up to 6,000 degrees Fahrenheit and sparks produced can fly or roll great distances. Smoldering material hidden from sight can suddenly burst into flame long after work has been completed and personnel have left the area. Heat produced by hot work on one side of a wall can actually ignite combustible material on the other side. Management of hot work is essential.
