Accidental contact of electrode or welding wire to
metal objects can cause sparks, overheating, or
re.
WARNING!
Sparks and spatter y o from the welding arc.
The ying sparks and hot metal, weld spatter,
work piece, and hot equipment can cause res
and burns.
Fire & Explosive Risks
1. Protect yourself and others from ying sparks
and hot metal.
2. Do not weld where ying sparks can strike
ammable material.
3. Remove all ammables 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 re, and keep a re extinguisher
nearby.
6. Be aware that welding on a ceiling, oor,
bulkhead, or partition can cause re on the
hidden side.
7. Do not weld on closed containers such as
tanks or drums.
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.
Cylinders
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 ttings designed for the specic
application; maintain them and their
associated parts in good condition.
6. Turn your face away from the valve outlet
when opening the cylinder valve.
3. If ventilation is poor, use an approved air-
supplied respirator.
4. Read the Safety Data Sheets (SDS) and the
manufacturer’s instruction for the metals,
consumables, coatings, and cleaners.
5. Work in a conned space only if it is well
ventilated, or while wearing an air-supplied
respirator. Shielding gases used for welding
can displace air causing injury or death. Be
sure the breathing air is safe.
6. Do not weld in locations near degreasing,
cleaning, or spraying operations. The heat and
rays of the arc can react with vapours to form
highly toxic and irritating gases.
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 o toxic
fumes if welded.
8. Connect the work lead/clamp to the job
as close to the welding area as practical to
prevent welding current from traveling long,
possibly unknown paths and causing electric
shock and re hazards.
9. Do not use a welder to thaw frozen pipes.
10. Remove the stick electrode from the holder
or cut o the welding wire at the contact tip
when not in use.
Sparks & Hot Metal
WARNING!
Chipping and grinding causes ying metal, and
as welds cool they can throw o slag.
1. Wear an AS/NZS approved face shield or safety
goggles. Side shields are recommended.
2. Wear appropriate safety equipment to protect
the skin and body.
