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.

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.

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 away 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.

17. The welding and cutting processes produces 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.
