explosive materials.
-Do not operate any electric arc
welder in areas where flammable or
explosive materials are present.
-Remove all flammable materials
within 35 feet of the welding arc. If
removal is not possible, tightly cover
them with fireproof covers.
-Take precautions to ensure that
flying sparks do not cause fires or
explosions in hidden areas, cracks or
areas you cannot see.
-Keep a fire extinguisher close in the
case of fire.
-Wear garments that are oil-free with
no pockets or cuffs that will collect
sparks.
-Do not have on your person any
items that are combustible, such as
lighters or matches.
-Keep work lead connected as close
to the weld area as possible to
prevent any unknown, unintended
paths of electrical current from
causing electrical shock and fire
hazards.
Hot Materials
Welded materials are hot
and can cause severe
burns if handled
improperly.
-Do not touch welded materials with
bare hands.
-Do not touch electrode holder after
welding until it has had time to cool
down.
Sparks/Flying Debris
Welding creates hot
sparks that can cause
injury. Chipping slag off
welds creates flying debris.
-Wear protective apparel at all times:
ANSI-approved safety glasses or
shield, welder’s hat and ear plugs to

sparks, open flames, mechanical
shocks or arcs.
-Do not touch cylinder with welding
cable.
-Do not weld on the cylinder.
-Always secure cylinder upright to a
cart or stationary object.
-Keep cylinders away from welding or
electrical circuits.
-Use the proper regulators, gas hose
