Welding produces fumes and gases. Breathing these fumes
and gases can be hazardous to your health
.
Keep your head
out of the fumes. Do not breathe the fumes.
If inside, ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases. If ventilation is poor, use an
approved air-supplied respirator.
Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator
. Always have a trained watch-
person 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 cleaning, or spraying operations
.
The heat and rays of the arc can react with vapours 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.
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.
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.
