Welding, Cutting, and Brazing
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.
Welding, cutting, and brazing is addressed in specific
standards for the general industry, shipyard employment, marine terminals, and
This section highlights OSHA standards, preambles to final rules (background to final rules), Federal Registers (rules, proposed rules, and notices), directives (instructions for compliance officers), and standard interpretations (official letters of interpretation of the standards) related to welding, cutting, and brazing.
Note: Twenty-five states, Puerto Rico and the Virgin Islands have OSHA-approved State Plans and have adopted their own standards and enforcement policies. For the most part, these States adopt standards that are identical to Federal OSHA. However, some States have adopted different standards applicable to this topic or may have different enforcement policies.

Hazards and Solutions
Health hazards from welding, cutting, and brazing operations include exposures to metal fumes and to ultraviolet (UV) radiation. Safety hazards from these operations include burns, eye damage, electrical shock, cuts, and crushed toes and fingers. Many of these can be controlled with proper work practices and personal protective equipment (PPE). The following links provide information about potential hazards and possible
solutions associated with these operations.
