15. Keep all panels and covers securely in place.
ARC RAYS can burn eyes and skin; NOISE
can damage hearing. Arc rays from the
welding process produce intense heat and
strong ultraviolet rays that can burn eyes
and skin. Noise from some processes can
damage hearing.
1. Wear a welding helmet fitted with a proper shade
of filter (see ANSI Z49.1 listed in Safety Standards)
to protect your face and eyes when welding or
watching.
2. Wear approved safety glasses. Side shields
recommended.

* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter
shade which gives sufficient view of the weld zone without going below the minimum. In oxyfuel gas
welding, cutting, or brazing where the torch and/or the flux produces a high yellow light, it is desirable
to use a filter lens that absorbs the yellow or sodium line of the visible light spectrum.

3. Use protective screens or barriers to protect others
from flash and glare; warn others not to watch the
arc.
4. Wear protective clothing made from durable,
flame-resistant material (wool and leather) and foot
protection.
5. Use approved ear plugs or ear muffs if noise level
is high.
FUMES AND GASES can be hazardous to
your health.
Welding produces fumes and gases.
Breathing these fumes and gases can be
hazardous to your health.
