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 having pacemakers should consult their physician 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 minimise 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 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 fumes from these materials.
3.
Do not operate near degreasing and spraying operations. The heat or arc can react
with chlorinated hydrocarbon vapors to form phosgene, a highly toxic gas and other
irritant gases.
4.
If you develop momentary eye, nose or throat irritation while operating, this is an
indication that ventilation is not adequate. Stop work and take necessary steps to
improve ventilation in the work area. Do not continue to operate if physical discomfort
persists.
5.
Refer to ANSI/ASC Standard Z49.1 for specific ventilation recommendations.
6.
WARNING: This product when used for welding or cutting, produces fumes or gases
which contain chemicals known to the State of California to cause birth defects and in
some cases cancer (California Health & Safety Code §25249.5 et seq.)
CYLINDER HANDLING
Cylinders, if mishandled, can rupture and violently release gas. A
sudden rupture of cylinder valve or relief device can injure or kill.
Therefore:
1.
Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.
2.
Use the proper gas for the process and use the proper pressure reducing regulator
designed to operate from the compressed gas cylinder. Do not use adaptors. Maintain
hoses and fittings in good condition. Follow manufacturer's operating instructions for
mounting regulator to a compressed gas cylinder.
