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.
WELDING can cause fire or explo-
sion.
Protect yourself and others from flying sparks and hot metal.
Do not weld where flying sparks can strike flammable material.
Remove all flammables within 35 ft (10.7 m) of the welding arc. If
this is not possible, tightly cover them with approved covers.
Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas.
Watch for fire, and keep a fire extinguisher nearby.
Be aware that welding on a ceiling, floor, bulkhead, or partition can
cause fire on the hidden side.
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).
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.
Do not use welder to thaw frozen pipes.
Remove stick electrode from holder or cut off welding wire at
contact tip when not in use.
Wear oil-free protective garments such as leather gloves, heavy
shirt, cuffless trousers, high shoes, and a cap.
Remove any combustibles, such as a butane lighter or matches,
from your person before doing any welding.
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.
CYLINDERS can explode if damaged.
Protect compressed gas cylinders from excessive heat, mechani-
cal shocks, slag, open flames, sparks, and arcs.
Install cylinders in an upright position by securing to a stationary
support or cylinder rack to prevent falling or tipping.
Keep cylinders away from any welding or other electrical circuits.
Never drape a welding torch over a gas cylinder.
Never allow a welding electrode to touch any cylinder.
Never weld on a pressurized cylinder – explosion will result.
Use only correct shielding gas cylinders, regulators, hoses, and fit-
tings designed for the specific application; maintain them and
associated parts in good condition.
Turn face away from valve outlet when opening cylinder valve.
Keep protective cap in place over valve except when cylinder is in
use or connected for use.
Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.

Engine Hazards
FUEL can cause fire or explosion.
Stop engine and let it cool off before checking or
adding fuel.
Do not add fuel while smoking or if unit is near
any sparks or open flames.
Do not overfill tank – allow room for fuel to expand.
Do not spill fuel. If fuel is spilled, clean up before starting engine.
Dispose of rags in a fireproof container.
MOVING PARTS can cause injury.
Keep away from fans, belts, and rotors.
Keep all doors, panels, covers, and guards
closed and securely in place.
Stop engine before installing or connecting unit.
Have only qualified people remove guards or covers for maint-
enance and troubleshooting as necessary.
To prevent accidental starting during servicing, disconnect
negative (–) battery cable from battery.
Keep hands, hair, loose clothing, and tools away from moving parts.
Reinstall panels or guards and close doors when servicing is
finished and before starting engine.
Before working on generator, remove spark plugs or injectors to
keep engine from kicking back or starting.
Block flywheel so that it will not turn while working on generator
components.
STEAM AND HOT COOLANT can burn.
If possible, check coolant level when engine is
cold to avoid scalding.
If the engine is warm and checking is needed,
follow the next two statements.
Wear safety glasses and gloves and put a rag over radiator cap.
Turn cap slightly and let pressure escape slowly before
completely removing cap.
BATTERY EXPLOSION can BLIND.
Always wear a face shield, rubber gloves, and
protective clothing when working on a battery.
Stop engine before disconnecting or connect-
ing battery cables or servicing battery.
Do not allow tools to cause sparks when working on a battery.
Do not use welder to charge batteries or jump start vehicles.
Observe correct polarity (+ and –) on batteries.
ENGINE HEAT can cause fire.
Do not locate unit on, over, or near combustible
surfaces or flammables.
Keep exhaust and exhaust pipes way from
flammables.
