§4853. Inert-Gas Metal-Arc Welding.

Employees shall not engage in and shall not be exposed to the inert-gas metal-arc welding process unless the following precautions are taken:

(a) Chlorinated solvents shall not be used within 200 feet (61 m) of the exposed arc. Surfaces prepared with chlorinated solvents shall be thoroughly dry before welding is performed on them.

(b) Employees in areas not protected from the arc by screening shall be protected by appropriate filter lenses in accordance with the requirements of Section 3382. When welders are exposed to their own arc or to each other's arc, filter lenses complying with the requirements of Section 3382 shall be worn to protect against flashes and radiant energy.

(c) Employees exposed to radiation shall have their skin covered completely to prevent ultraviolet burns and damage. Helmets and hand shields shall not have leaks, openings or highly reflective surfaces.

(d) Inert-gas metal-arc welding on stainless steel shall not be performed unless exposed employees are protected either by local exhaust ventilation or by wearing supplied air respirators.
