Welding, Cutting, and Brazing
National Summary

This topic covers OSHA’s regulations for welding, cutting, and brazing operations in general industry workplaces (29 CFR 1910.251-255), also known as “hot work” activities.

Welding, cutting, and brazing are hazardous activities that pose a unique combination of both safety and health risks to more than 500,000 workers in a wide variety of industries. The risk from fatal injuries alone is more than four deaths per thousand workers over a working lifetime. For these reasons, OSHA has developed several regulations designed to protect workers from injuries and illnesses related to welding, cutting, and brazing operations.
