1 SAFETY
ELECTRICAL SHOCK
Contact between live electrical parts and earth can cause severe injury
or death. DO NOT use AC welding current in damp areas, if movement
is confined, or if there is danger of falling. Therefore:
1.
Be sure the power source frame (chassis) is connected to the earth system of the
input power.
2.
Connect the workpiece to a good electrical earth.
3.
Connect the work cable to the workpiece. A poor or missing connection can expose
you or others to a fatal shock.
4.
Use well-maintained equipment. Replace worn or damaged cables.
5.
Keep everything dry, including clothing, work area, cables, torch/electrode holder and
power source.
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 dry boards or 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 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 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. Do not breathe the fumes and gases.
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.
