ARC RAYS can burn eyes and skin. BUILDUP OF GAS can injure or kill. Shut off shielding gas supply when not in use. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays Always ventilate confined spaces or use that can burn eyes and skin. Sparks fly off from the approved air-supplied respirator. weld. Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 li
