1910.252(c)(11): Cleaning Compounds Near Welding

By Black Belt Safety Editorial Team Official text as of octubre 15, 2026 Data updated octubre 24, 2026 3 min read

In plain words:

When using cleaning materials, employers must follow appropriate precautions such as manufacturer's instructions because of possible toxicity or flammability. Degreasing and cleaning with chlorinated hydrocarbons must be located so no vapors reach or are drawn into the air around any welding, and trichloroethylene and perchlorethylene should be kept out of air reached by ultraviolet radiation from gas-shielded welding.
