FUMES AND GASES 

 

WARNING

 

Welding produces fumes and gases. Breathing 
these fumes and gases can be hazardous to your 
health.

1.  Keep your head out of the fumes. Do not breathe

the fumes.

2.  If inside, ventilate the area and/or use an exhaust

at the arc to remove welding fumes and gases.

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 confined 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 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 current 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

goggles. Side shields are recommended.

2.  Wear appropriate safety equipment to protect

the skin and body.

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 equip-
ment 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
condition.

6.  Turn your face away from the valve outlet when

opening the cylinder valve.
