Guidelines

This checklist covers regulations issued by the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) under the general industry standard 29 CFR 1910.25 and the construction standards 29 CFR 1926.351, 1926.352, 1926.353, and 1926.354. The checklist applies to operations involving welding, cutting, brazing, and heating. This checklist does not cover in detail regulations dealing with work in confined or enclosed spaces. If these conditions are encountered, please consult 29 CFR 1910.146, 1910.252, and 1926.353. The regulations cited apply only to private employers and their employees, unless adopted by a State agency and applied to other groups such as public employees. A yes answer to a question indicates that this portion of the inspection complies with the OSHA or U.S. Environmental Protection Agency (EPA) standard, or with a nonregulatory recommendation.

  1. Fire Prevention and Protection

  2. Are all moveable fire hazards and combustibles moved to at least 35 feet away from areas or objects to be welded? [29 CFR 1910.252(a)(1)(i) and 1910.252(a)(2)(vii) and 1926.352(a)]
  3. When welding or cutting operations are performed within 35 feet of combustible materials or floor, ceiling, or wall openings, are guards, barriers, or other precautions used to confine heat sparks and slag? [29 CFR 1910.252(a)(1)(ii), 29 CFR 1910.252(a)(2)(iii)(A), and 1926.352(b)]

    Note: If all fire hazards cannot be removed or when the floor, ceiling, or wall has openings, special precautions listed in 1910.252(a)(2) and 1926.352(e) and (f) may be necessary. These requirements include having fire watchers present during and up to 30 minutes after the job is done; having an inspection conducted before beginning work; covering or wetting combustible materials; relocating combustibles; and covering or shutting down ventilation ducts and conveyors. In some cases, welding or cutting is prohibited if sprinkler systems are inoperable or unusual fire and explosion hazards exist.

  4. Is welding prohibited where flammable materials are used (such as paints) or where heavy dust concentrations are present? [29 CFR 1926.352(c)]
  5. Is suitable fire extinguishing equipment kept where welding or cutting is done? Is this equipment ready for instant use? [29 CFR 1910.252(a)(2)(ii) and 1926.352(d)]
  6. When students or employees weld or cut containers such as barrels or tanks, are the containers thoroughly cleaned to remove materials that, when heated, may cause fire, explosion, or release of toxic materials? [29 CFR 1910.252(a)(3)(i) and 1926.352(i)]

    Note: The construction regulations in 1926.352(i) also permit barrels or tanks to be filled with water as an alternative to cleaning.

  7. Before welding or cutting containers, are all hollow spaces and cavities vented to release trapped air or gases? [29 CFR 1910.252(a)(3)(ii) and 1926.352(j)]

    Note: Purging with inert gas is recommended.

    Protection of Personnel

  8. Are welding cables and hoses kept clear of passageways, ladders, and stairways? [29 CFR 1910.252(b)(1)(ii)]
  9. Are welders, cutters, brazers, and helpers given suitable face, neck, and ear protection to prevent direct radiant energy from the arc? [29 CFR 1910.252(b)(2)(ii)(B)]
  10. Are welders, cutters, brazers, and helpers given suitable eye protection with proper filter lens shade numbers? [29 CFR 1910.252(b)(2) and 1926.353(e)(2)]

    Note: The following is a guide for selecting proper shade numbers. These recommendations may vary to suit individual needs: [29 CFR 1910.252(b)(2)(ii)(H)]

    *Note: In gas welding or oxygen cutting in which the torch produces a high yellow light, use a filter or lens that absorbs the yellow or sodium line in the visible light of the operation.
