1 SAFETY PRECAUTIONS
6. Make sure that all parts of your body are insulated from both the work piece and from
the ground.
7. Do not stand directly on metal or the ground while working in tight quarters or a damp
area; stand on an effective insulation layer, such as dry boards, an insulating platform,
and wear rubber-soled shoes.
8. Put on dry, hole-free gloves before turning on the power.
9. Turn off the power, before removing your gloves.
10. Refer to ANSI/ASC Standard Z49.1 for specific grounding recommendations. Do not
mistake the work lead for a earth cable.
ELECTRIC AND MAGNETIC FIELDS
May be dangerous. Electric current flowing through any conductor
causes localized Electric and Magnetic Fields (EMF). Welding and
cutting current creates EMF around welding cables and welding
machines. Therefore:
1. Welders with medical pacemakers fitted should consult their doctor before welding.
EMF may interfere with some pacemakers.
2. Exposure to EMF may have other health effects which are unknown.
3. Welders should use the following procedures to minimize exposure to EMF:
a) Route the electrode and work cables together. Secure them with tape when
possible.
b) Never coil the torch or work cable around your body.
c) Do not place your body between the torch and work cables. Route cables
together on the same side of your body.
d) Connect the work cable to the workpiece as close as possible to the area being
welded.
e) Keep the welding power source and cables as far away from your body as
possible.
FUMES AND GASES
Fumes and gases, can cause discomfort or harm, particularly in
confined spaces. Shielding gases can cause asphyxiation. Therefore:
1. Keep your head out of the fumes, smoke, and vapors. Do not breathe the smoke,
fumes, and gases that are generated by welding processes.
2. Always provide adequate ventilation in the work area by natural or mechanical means.
Do not weld, cut or gouge on materials such as galvanized steel, stainless steel,
copper, zinc, lead beryllium or cadmium unless positive mechanical ventilation is
provided. Do not breathe in the fumes from these materials.
3. Orient the ventilation to draw smoke, fumes, and vapors in a direction away from the
welding operator. Position ventilation suction to pull welding fumes and smoke from
the far side of the work area if possible
4. Provide general ventilation for the surrounding work area if there is a risk of workers or
other persons beyond the immediate work area getting exposed to significant welding
fumes. Monitor the fugitive fumes and smoke for potential collateral exposures. Install
appropriate ventilation controls or cease surrounding activity if fumes become an
exposure issue outside of the immediate work area
5. Do not operate near degreasing and spraying operations. The heat or arc can react
with chlorinated hydrocarbon vapors or liquids to form phosgene, a highly toxic gas,
and other irritant gases.
