Current through Register Vol. 24-14, July 15, 2024
(1) Helmets and hand shields must be made of
				  a material that is an insulator for heat and electricity. Helmets, shields and
				  goggles must be not readily flammable and must be able to be
				  sterilized.
(2) Helmets and hand
				  shields must be arranged to protect the face, neck and ears from direct radiant
				  energy from the arc.
(3) Helmets
				  must have filter plates and cover plates designed for easy removal.
(4) All parts must be constructed of a
				  material that will not readily corrode or discolor the skin.
(5) Goggles must be ventilated to prevent
				  fogging of the lenses as much as practical.
(6) Cover lenses or plates should be provided
				  to protect each helmet, hand shield, or goggle filter lens or plate.
(7) All glass for lenses must be tempered,
				  substantially free from scratches, air bubbles, waves and other flaws. Except
				  when a lens is ground to provide proper optical correction for defective
				  vision, the front and rear surfaces of lenses and windows must be smooth and
				  parallel.
(8) Lenses must be marked
				  with the source and shade.
(9)
				  Following is a guide to select proper shade numbers. Individual needs may vary.
Welding Operation
Shade No.
Shielded metal-arc welding-1/16-, 3/32-, 1/8-,
							 5/32-inch electrodes

Gas-shielded arc welding (nonferrous)-1/16-, 3/32-,
							 1/8-, 5/32-inch electrodes
11
Gas-shielded arc welding (ferrous)-1/16-, 3/32-,1/8-,

Torch brazing
3 or 4
Light cutting, up to 1 inch
3 or 4
Medium cutting, 1 inch to 6 inches
4 or 5
Heavy cutting, 6 inches and over
5 or 6
Gas welding (light) up to 1/8 inch
4 or 5
Gas welding (medium) 1/8 inch to 1/2 inch
5 or 6
Gas welding (heavy) 1/2 inch and over
6 or 8
Note:
In gas welding or oxygen cutting where the torch
								produces a high yellow light it is desirable to use a filter or lens that
								absorbs the yellow or sodium line in the visible light of the
								operation.
(10) All filter lenses and plates must meet
				  the test for transmission of radiant energy prescribed in ANSI Z
				  87.1-1968-American National Standard Practice for Occupational and Educational
				  Eye and Face Protection.
(11) Where
				  the work permits, an arc 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 must be
				  enclosed with noncombustible screens similarly painted. Booths and screens must
				  permit circulation of air at floor level. Employees or other persons adjacent
				  to the welding areas must be protected from the rays by noncombustible or
				  flameproof screens or shields or must be required to wear appropriate
				  goggles.
