•Install and maintain equipment according to NEC code, refer to item 9 in Subsection 1.03, Publica- tions.

•Disconnect power source before performing any ser- vice or repairs.

•Read and follow all the instructions in the Operat- ing Manual.

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 mate- rial 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 combustibles.

•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 under- water 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 dis- sipated. Trapped hydrogen gas that is ignited will cause an explosion.

NOISE

Noise can cause permanent hearing loss. Plasma arc pro- cesses can cause noise levels to exceed safe limits. You must protect your ears from loud noise to prevent per- manent loss of hearing.

•To protect your hearing from loud noise, wear pro- tective ear plugs and/or ear muffs. Protect others in the workplace.

•Noise levels should be measured to be sure the deci- bels (sound) do not exceed safe levels.

•For information on how to test for noise, see item 1 in Subsection 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 hel- met or shield. Also always wear safety glasses with side shields, goggles or other protective eye wear.

•Wear welding gloves and suitable clothing to pro- tect 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:
