Cylinders
WARNING!
Gas cylinders contain gas under high pressure.
If damaged, a cylinder can explode. Since gas
cylinders are normally part of the welding
process, be sure to treat them carefully.
1. Protect compressed gas cylinders from excessive
heat, mechanical shocks, and arcs.
2. Install and secure cylinders in an upright position
by chaining them to a stationary support or
equipment cylinder rack to prevent falling or tipping.
3. Keep cylinders away from any welding or other
electrical circuits.
4. Never allow a welding electrode to touch any
cylinder.
5. Use appropriate shielding gas, regulators, hoses, and
fittings designed for the specific application;
maintain them and their associated parts in good con-
dition.
6. Turn your face away from the valve outlet when
opening the cylinder valve.
7. 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.
Fire & Explosive Risks
WARNING!
Sparks and spatter fly off from the welding
arc. The flying sparks and hot metal, weld
spatter, work piece, and hot equipment can
cause fires and burns.
Accidental contact of electrode or welding wire to metal
objects can cause sparks, overheating, or fire.
1. Protect yourself and others from flying sparks and
hot metal.
2. Do not weld where flying sparks can strike
flammable material.
3. Remove all flammables within 10m of the
welding site.
4. Be alert that welding sparks and hot materials
from welding can easily go through small cracks
and openings to adjacent areas.
5. Watch for fire, and keep a fire extinguisher
nearby.
6. Be aware that welding on a ceiling, floor, bulkhead,
or partition can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks or
drums.
8. Connect the work lead/clamp to the job as close
to the welding area as practical to prevent welding
cur-rent from travelling long, possibly unknown
paths and causing electric shock and fire hazards.
9. Do not use a welder to thaw frozen pipes.
10. Remove the stick electrode from the holder or cut
off the welding wire at the contact tip when not in
use.
Sparks & Hot Metal
WARNING!
Chipping and grinding causes flying metal, and
as welds cool they can throw off slag.
1. Wear an AS/NZS approved face shield or safety
gog-gles. Side shields are recommended.
2. Wear appropriate safety equipment to protect the
skin and body.
