5.2.2
Buildup of Gas
BUILDUP OD GAS CAN INURE OR KILL
Shut off shielding gas supply when not in use.
Always ventilate confined spaces or use approved air-supplied respirator.
5.2.3
Electric and Magnetic Fields (EMF)
ELECTRIC AND MAGNETIC FIELDS (EMF) CAN AFFECT IMPLANTED MEDICAL DEVICES
Wearers of Pacemakers and other Implanted Medical Devices should keep away!
Implanted Medical Device wearers should consult their doctor and the device manufacturer before
going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations.
5.2.4
Noise
Noise from some processes or equipment can damage hearing.
Wear approved ear protection if noise level is high.
5.2.5
Cylinders
CYLINDERS CAN EXPLODE IF DAMAGED
Compressed 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.
Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage,
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 compressed gas cylinders, regulators, hoses, and fittings 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.
Use the right equipment, correct procedures, and sufficient number of persons to lift and move
cylinders.
Read and follow instruction on compressed gas cylinders associated equipment, and Compressed
Gas Association (CGA) publication P-1,
Safe Handling of Compressed Gases in Cylinders
listed in
Principle Safety Standards
