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.
WARNING
WELDING can cause fi re or explosion.
Sparks and spatter fl y off from the welding arc.
The fl ying sparks and hot metal, weld spatter,
hot workpiece, and hot equipment can cause
fi res and burns. Accidental contact of electrode
or welding wire to metal objects can cause
sparks, overheating, or fi re.
1. Protect yourself and others from fl ying sparks and hot
metal.
2. Do not weld where fl ying sparks can strike fl ammable
material.
3. Remove all fl ammables within 35 ft. (10.7M) 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 fi re, and keep a fi re extinguisher nearby.
6. Be aware that welding on a ceiling, fl oor, bulkhead, or
partition can cause fi re on the hidden side.
7. Do not weld on closed containers such as tanks or
drums.
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 fi re 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.
WARNING
FLYING SPARKS AND HOT METAL can cause
injury.
Chipping and grinding cause fl ying metal. As
welds cool, they can throw off slag.
1. Wear approved face shield or safety goggles. Side
shields recommended.
2. Wear proper body protection to protect skin.
WARNING
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 fi ttings designed for the specifi c 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.
