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.
• 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 work-pieces 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.
• Operator should 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.
PLASMA ARC RAYS
Plasma Arc Rays can injure your eyes and burn your skin. The plasma arc process produces very bright
ultra violet and infrared light. These arc rays will damage your eyes and burn your skin if you are not properly
protected.
• Wear safety glasses with specified UV/IR DIN 1.7-6.0 with side shields other protective eye wear.
• Wear cutting gloves and suitable clothing to protect your skin from the arc rays and sparks.
