•
Work in a confined space only if it is well ventilated, or while wearing an air-
supplied respirator. Always have a trained watchperson nearby. Welding
fumes and gases can displace air and lower the oxygen level causing injury
or death. Be sure the breathing air is safe.
•
Do not weld in locations near degreasing, cleaning, or spraying operations.
The heat and rays of the arc can react with vapors to form highly toxic and
irritating gases.
•
Do not weld on coated metals, such as galvanized, lead, or cadmium plated
steel, unless the coating is removed from the weld area, the area is well
ventilated, and if necessary, while wearing an air-supplied respirator. The
coatings and any metals containing
these elements can give off toxic fumes
if welded.
•
Shut off shielding gas supply when not in use.
ARC RAYS can burn eyes and skin
.
Arc rays from the welding process produce intense visible and
invisible (ultraviolet and infrared) rays that can burn eyes and
skin. Sparks fly off from the 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 listed in
Safety Standards 1.4).
•
Wear approved safety glasses with side shields under your helmet.
•
Use protective screens or barriers to protect others from flash and glare;
warn others not to watch the arc.
•
Wear protective clothing made from durable, flame-resistant material
(leather and wool) and foot protection.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks, drums, or pipes,
can cause them to blow up. Sparks can fly off from the welding
arc. The flying sparks, hot work-piece, and hot equipment can
cause fires and burns. Accidental contact of electrode to metal
objects can cause sparks, explosion, overheating, or fire. Check
and be sure the area is safe before doing any welding.
