FLYING SPARKS
Can Cause Injury
FLYING SPARKS AND HOT METAL can cause
injury.
Chipping and grinding cause flying 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.
CYLINDERS Can
Explode If Damaged
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.
IMPORTANT SAFETY INSTRUCTIONS
WELDING Can
Cause Fire or Injury
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. 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 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 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
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. When not welding, make certain no part of the
electrode circuit is touching the work or
ground. Accidental contact can cause
overheating and create a fire hazard.
