D Protect compressed gas cylinders from excessive heat, mechanical
shocks, physical damage, slag, open flames, sparks, and arcs.
D Install cylinders in an upright position by securing to a stationary support
or cylinder rack to prevent falling or tipping.
D Keep cylinders away from any welding or other electrical circuits.
D Never drape a welding torch over a gas cylinder.
D Never allow a welding electrode to touch any cylinder.
D Never weld on a pressurized cylinder − explosion will result.
D Use only correct compressed gas cylinders, regulators, hoses, and fit-
tings designed for the specific application; maintain them and asso-
ciated parts in good condition.
D Turn face away from valve outlet when opening cylinder valve.
D Keep protective cap in place over valve except when cylinder is in use or
connected for use.
D Use the right equipment, correct procedures, and sufficient number of
persons to lift and move cylinders.
D Read and follow instructions on compressed gas cylinders, associated
equipment, and Compressed Gas Association (CGA) publication P-1
listed in Safety Standards.

CYLINDERS can explode if damaged.
Compressed gas cylinders contain gas under high pres-
sure. If damaged, a cylinder can explode. Since gas
cylinders are normally part of the welding or cutting process,
be sure to treat them carefully.
BUILDUP OF GAS can injure or kill.
D Shut off compressed gas supply when not in use.
D Always ventilate confined spaces or use approved
air-supplied respirator.
FLYING METAL or DIRT can injure eyes.
D Welding, chipping, wire brushing, and grinding
cause sparks and flying metal. As welds cool,
they can throw off slag.
D Wear approved safety glasses with side
shields even under your welding helmet.
