CYLINDERS CAN EXPLODE IF DAMAGED
• Gas cylinders contain gas under very high pressure. If damaged they can result in that cylinder ex-
ploding. Gas cylinders are a major part of metalworking and must be treated with care.
• Protect gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs
• Always keep cylinders in an upright position securely fastened to a fixed support
• Valve protection caps should always be in place and hand tight except when the cylinder is in use
• Keep all cylinders away from any welding or electrical circuits
• Never allow the flame or arc from a welder to contact a cylinder
• Never cut any type of pressurized cylinder, an explosion could result
• Always turn your face away from the valve when opening the cylinder
• Read and follow all instructions on compressed gas cylinders, associated equipment, and CGA pub-
lication P-1 listed in the Safety Standards before using
HOT PARTS CAN CAUSE SERIOUS BURNS
• Do not touch hat parts without wearing protection.
• Allow the torch to cool sufficiently before working with parts that could potentially be hot.
NOISE CAN DAMAGE HEARING
• Prolonged noise exposure from welding equipment can cause damage if levels of noise exceed the
OSHA standards
• Wear approved hearing protectors
• Warn other workers nearby of the high noise level and hazard
CALIFORNIA PROPOSITION 65 WARNINGS
• Welding or cutting equipment produces fumes or gases which contain chemicals known to the State of California to cause
birth defects, and in some cases, cancer. (California Health and Safety Code Section 25249.5 et seq.)
