welding fumes and gases.
If ventilation is poor, wear an approved air-
supplied respirator.
Read and understand the Material Safety
Data Sheets (MSDS’s) and the
manufacturer’s instructions for metals,
consumables, coatings, cleaners, and
degreasers.
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 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 while
wearing an air-supplied respirator. The
coatings and any metals containing these
elements can give off toxic fumes if welded.
1.4.3
BUILD UP OF GAS CAN INJURE
OR KILL
Shut off shielding gas supply
when not in use.
Always ventilate confined
spaces or use approved air-
supplied respirator.
1.4.4
ENCLOSED SPACES CAN CAUSE A
BUILD-UP OF NOXIOUS FUMES
AND OVERHEATING
Do not use in enclosed
spaces where deadly
exhaust gases can build up
and machine can overheat,
causing fire.
1.4.5
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 an approved welding helmet fitted with
a proper shade of filter lenses to protect your
face and eyes from arc rays and sparks
when welding or watching.
(See ANSI Z49.1 and Z87.1 listed in Safety
Standards). Wear approved safety glasses
with side shields under your helmet.
Use protective screens or barriers to protect
others from flash, glare, and sparks; warn
others not to watch the arc.
Wear protective clothing made from durable,
flame-resistant material (leather, heavy
cotton, or wool) and foot protection.
1.4.6
WELDING CAN CAUSE FIRE
AND 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
workpiece, and hot equipment can cause
fires and burns. Accidental contact of
electrode to metal objects can cause sparks,
explosion, overheating, or fire. Check and
ensure the area is safe before doing any
welding.
Remove all flammables within 35 ft (10.7 m)
of the welding arc. If this is not possible,
tightly cover them with approved covers.
Do not weld where flying sparks can strike
flammable material.
Protect yourself and others from flying
sparks and hot metal.
