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.
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 cutting helmet or
shield. Also always wear safety glasses with side shields,
goggles or other protective eye wear.
• Wear cutting 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.
