CYLINDERS can explode if damaged.
Shielding 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 only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
6.- Turn face away from valve outlet when opening cylinder valve.
7.- Keep protective cap in place over valve except when cylinder is in
use or connected for use.
8.- Read and follow instructions on compressed gas cylinders, associated
equipment, and CGA publication P-1 listed in Safety Standards.
ENGINES can be hazardous.
WARNING
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
1.- Use equipment outside in open, well-ventilated
areas.
2.- If used in a closed area, vent engine exhaust outside and away from
any building air intakes.
E NG I NE F UE L can cau se f ire o r
explosion
.
Engine fuel is highly flammable.
1.- Stop engine before checking or adding fuel.
2.- Do not add fuel while smoking or if unit is near any sparks or open
flames.
3.- Allow engine to cool before fueling. If possible, check and add fuel
to cold engine before beginning job.
4.- Do not overfill tank - allow room for fuel to expand.
5.- Do not spill fuel. If fuel is spilled, clean up before starting engine.
MOVING PARTS can cause injury.
Moving parts, such as fans, rotors, and belts can cut
fingers and hands and catch loose clothing.
1.- Keep all doors, panels, covers, and guards closed
and securely in place.
2.- Stop engine before installing or connecting unit.
3.- Have only qualified people remove guards or covers for maintenance
and troubleshooting as necessary.
4.- To prevent accidental stating during servicing, disconnect negative
(-) battery cable from battery.
5.- Keep hands, hair, loose clothing, and tools away from moving parts.
6.- Reinstall panels or guards and close doors when servicing is finished
and before starting engine.
SPARKS can cause BATTERY GA-
SES T O EXPLODE; BATTERY ACID
can burn eyes and skin.
Batteries contain acid and generate explosive gases.
1.- Always wear a face shield when working on a
battery.
2.- Stop engine before disconnecting or connecting battery cables.
3.- Do not allow tools to cause sparks when working on a battery.
4.- Do not use welder to charge batteries or jump start vehicles.
5.- Observe correct polarity (+ and -) on batteries.
WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The
flying sparks and hot metal, weld spatter, hot workpiece,
and hot equipment can cause fires and burns. Acciden-
tal 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 35ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
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 surch as tanks or drums.
8.- Connect work cable to the work as close to the welding areas as
practical to prevent welding current from traveling long, possibly
unknown paths and causing electric shock and fire hazards.
9.- Do not use welder to thaw frozen pipes.
10.- Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
11.- Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
