GENERAL INFORMATION

Manual 0-5096

FIRE AND EXPLOSION

Fire and explosion can be caused by hot slag, sparks, or the plasma arc.

• Be sure there is no combustible or flammable material in the

workplace. Any material that cannot be removed must be

protected.

• Ventilate all flammable or explosive vapors from the workplace.
• Do not cut or weld on containers that may have held combus-

tibles.

• Provide a fire watch when working in an area where fire hazards

may exist.

• Hydrogen gas may be formed and trapped under aluminum

workpieces when they are cut underwater or while using a water

table. DO NOT cut aluminum alloys underwater or on a water

table unless the hydrogen gas can be eliminated or dissipated.

Trapped hydrogen gas that is ignited will cause an explosion.

NOISE

Noise can cause permanent hearing loss. Plasma arc processes can

cause noise levels to exceed safe limits. You must protect your ears

from loud noise to prevent permanent loss of hearing.

• To protect your hearing from loud noise, wear protective ear

plugs and/or ear muffs. Protect others in the workplace.

• Noise levels should be measured to be sure the decibels (sound)

do not exceed safe levels.

• For information on how to test for noise, see item 1 in Subsec-

tion 1.03, Publications, in this manual.

PLASMA ARC RAYS

Plasma Arc Rays can injure your eyes and burn your skin. The plasma

arc process produces very bright ultra violet and infra red light. These

arc rays will damage your eyes and burn your skin if you are not

properly protected.

• To protect your eyes, always wear a welding helmet or shield.

Also always wear safety glasses with side shields, goggles or

other protective eye wear.

• Wear welding gloves and suitable clothing to protect your skin

from the arc rays and sparks.

• Keep helmet and safety glasses in good condition. Replace

lenses when cracked, chipped or dirty.

• Protect others in the work area from the arc rays. Use protective

booths, screens or shields.

• Use the shade of lens as suggested in the following per ANSI/

ASC Z49.1:

Experience has shown that lighter filters may be used

when the arc is hidden by the workpiece.
