SM-QRLTORCH SAFETY INSTRUCTIONS AND WARNINGS
WARNING
WELDING SPARKS CAN CAUSE FIRES AND
EXPLOSIONS.
23. Causes of fire and explosion are: combustibles reached by
the arc, flame, flying sparks, hot slag, or heated material.
Remove combustibles from the work area and/or provide
a fire watch.
24. Avoid oily or greasy clothing as sparks may ignite them. Have
a fire extinguisher nearby, and know how to use it.
25. Be alert to the danger of conduction or radiation. For
example, if welding or cutting is to be done on a metal
wall, partition, ceiling, or roof, precautions must be taken
to prevent ignition of combustibles on the other side.
26. Do not weld or cut containers that have held combustibles.
All hollow spaces, cavities and containers should be
vented prior to welding or cutting to permit the escape
of air or gases. Purging with inert gas is recommended.
27. Never use oxygen in a welding torch. Use only inert
gases or inert gas mixes as required by the process. Use
of combustible compressed gases can cause explosions
resulting in personal injury or death. Arcing against any
compressed gas cylinder can cause cylinder damage or
explosion.
WARNING
NOISE CAN DAMAGE HEARING.
28. Noise from the air carbon-arc process can damage your
hearing. Wear protective hearing devices to ensure protection
when noise levels exceed OSHA standards. Adequate
hearing protection devices must be worn by operators and
surrounding personnel to ensure personal protection against
noise.
11. Keep smoke, fumes, and gases from the breathing area.
12. Fumes from the welding or cutting process are of various
types and strengths, depending on the kind of base metal
being worked on. To ensure your safety, do not breathe these
fumes.
13. Ventilation must be adequate to remove smoke, fumes, and
gases during the operation to protect operators and other
personnel in the area.
14. Vapors of chlorinated solvents can form the toxic gas
“Phosgene” when exposed to ultraviolet radiation from an
electric arc. All solvents, degreasers, and potential sources
of these vapors must be removed from the work area.
15. Fumes produced by welding or cutting, particularly in confined
places, can cause discomfort and physical harm if inhaled over
an extended period of time.
16. Provide adequate ventilation in the welding or cutting area.
Use air-supplied respirators if ventilation is not adequate to
remove all fumes and gases. Never ventilate with oxygen.
Oxygen supports and vigorously accelerates fire.
WARNING
ARC RAYS, HOT SLAG AND SPARKS CAN INJURE
EYES AND BURN SKIN .
17. The welding and cutting processes produce extreme localized
heat, and strong ultraviolet rays.
18. Never attempt to weld or cut without a welding helmet with
the proper lens. Ensure that the lens complies with federal
guidelines. A number 12 to 14 shade filter lens provides the
best protection against arc radiation. When in a confined
area, prevent the reflected arc rays from entering around the
helmet.
19. Ensure all personnel in the work area are protected from arc
rays and sparks. Approved shielding curtains and appropriate
goggles should be used to provide protection to staff in the
surrounding area and operators of nearby equipment.
20. Unprotected skin should also be covered from arc rays, heat
and molten metal. Always wear protective gloves and clothing
that does not allow skin to become exposed. All pockets
should be closed and cuffs sewn shut. Leather aprons, sleeves,
leggings, etc., should be worn for out-of-position welding and
cutting or for heavy operations using large electrodes. High top
work shoes provide adequate protection from foot burns.
For added protection use leather spats.
21. Flammable hair preparations should not be used when
welding or cutting. Wear ear plugs to protect ears from
sparks.
22. Where the work area permits, the operator should be
enclosed in an individual booth painted with a finish of
low reflectivity such as zinc oxide. This is an important
factor for absorbing ultraviolet radiations, and lamp black.
The operator should be enclosed with non-combustible
screens similarly painted.
