Optical Radiation:
Welding Protection
 The intensity of visible light and radiant energy
produced by welding operations varies depending
on the task, the electrode size, and the arc current. Workers involved in welding,
cutting, and brazing operations must use appropriate
welding protection depending on specific
welding operations. [1926.102(a)(5)]
Only filter lenses with the appropriate shade number will provide
protection against optical radiation. Filter lenses
must coincide to specific radiant energy exposure.
Welding protectors are constructed of heat resistant material such
as vulcanized fiber or fiberglass and fitted with a filtered lens to
protect workers eyes from burns caused by infrared or other intense
radiant energy. These devices protect the eyes and face from flying
sparks, metal spatter, and slag chips produced during welding,
brazing, soldering, and cutting.
Welding helmets are secondary protectors intended to shield the eyes
and face from optical radiation, heat, and impact. Use welding
helmets in
addition to primary protection such as safety
spectacles or goggles to provide adequate
protection.
