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, slag, open flames, sparks, and arcs.
2.
Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
3.
Keep cylinders away from any welding or other electrical
circuits.
4.
Never drape a welding torch over a gas cylinder.
5.
Never allow a welding electrode to touch any cylinder.
6.
Never weld on a pressurized cylinder – explosion will result.
7.
Use only correct shielding gas cylinders, regulators, hoses, and
fittings designed for the specific application; maintain them and
associated parts in good condition.
8.
Turn face away from valve outlet when opening cylinder valve.
9.
Keep protective cap in place over valve except when cylinder is
in use or connected for use.
10. Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.
WELDING can cause fire or 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 be sure the area is safe before
doing any welding.
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 35 ft (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 such as tanks, drums, or
pipes, unless they are properly prepared according to AWS F4.1
(see Safety Standards).
8.
Connect work cable to the work as close to the welding area 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.
12. Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.

Engine Hazards
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.
WARNING
ENGINE FUEL can cause fire or
explosion.
Engine fuel is highly flammable.
1.
Stop engine and let it cool off before checking or adding fuel.
2.
Do not add fuel while smoking or if unit is near any sparks or
open flames.
3.
Do not overfill tank – allow room for fuel to expand.
4.
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 starting 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 GASES
TO 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.
STEAM AND PRESSURIZED HOT
COOLANT can burn face, eyes, and
skin.
It is best to check coolant level when engine is
cold to avoid scalding.
1.
If the engine is warm and checking is needed, follow steps 2
and 3.
2.
Wear safety glasses and gloves and put a rag over cap.
3.
Turn cap slightly and let pressure escape slowly before
completely removing cap.
