What is the minimum eye protection required for workers who walk through/work in areas where welding is being done?

At 1910.252(b)(2)(iii), “Protection from arc welding rays,” OSHA says that “Where the work permits, the welder should be enclosed in an individual booth painted with a finish of low reflectivity such as zinc oxide (an important factor for absorbing ultraviolet radiations) and lamp black, or shall be enclosed with non-combustible screens similarly painted. Booths and screens shall permit circulation of air at floor level. Workers or other persons adjacent to the welding areas shall be protected from the rays by noncombustible or flame-proof screens or shields or shall be required to wear appropriate goggles.”

As such, OSHA would first prefer that employers use screens or shields to protect employees who walk through welding areas. If not, then “appropriate goggles” must be provided for those employees.
