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.

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.
• 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.
• Keephelmetandsafetyglassesingoodcondition.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 chart.
NOTE
These values apply where the actual arc is clearly seen.
Experience has shown that lighter filters may be used
when the arc is hidden by the workpiece.
