SAFETY
FUMES AND GASES CAN BE DANGEROUS.
5 a. Welding may produce fumes and gases hazardous to health Avoid breathing these fumes and gases. When welding, keep
your head out Of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing
zone. When welding
hardfacing (see instructions on container or SDS) or on lead or cadmium plated steel and other
metals or coatings which produce highly toxic fumes, keep exposure as low as possible and within applicable OSHA
PEL and ACGIH TLV limits using local exhaust or mechanical ventilation unless exposure assessments indicate other-
wise. In confined spaces or in some circumstances, outdoors, a respirator may also be required. Additional precau-
tions are also required when welding on galvanized steel.
5 b. The operation Of welding fume control equipment is affected by various factors including proper use and positioning Of the
equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level
should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV
limits
5 c. Do not weld in locations near chlorinated hydrocarbon vapors coming from degreasing, cleaning or spraying operations The
heat and rays of the arc can react with solvent vapors to form phosgene, a highly toxic gas, and other irritating products
5 d. Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in
confined areas, to insure breathing air is safe.
5.e. Read and understand the manufacturer's instructions for this equipment and the consumables to be used, including the Safety
Data Sheet (SDS) and follow your employer's safety practices. SDS forms are available from your welding distributor or from
the manufacturer.
5 f. Also see item 1 b
WELDING AND CUTTING SPARKS CAN CAUSE FIRE OR EXPLOSION.
6 a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire
Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent ar
eas_ Avoid welding near hydraulic lines Have a fire extinguisher
readily available
6 b. Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous situations.
Refer to "Safety in Welding and Cutting" (ANSI Standard Z49.1) and the operating information for the equipment being used
6 c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause
overheating and create a fire hazard.
6 d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will
not cause flammable or toxic vapors from substances inside. They can cause an explosion even though they have been
"cleaned". For information, purchase "Recommended Safe Practices for the Preparation for Welding and Cutting of Containers
and Piping That Have Held Hazardous Substances", AWS F4_1 from the American Welding Society (see address above)
6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode
6 f. Sparks and spatter are thrown from the welding arc Wear oil free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair Wear ear plugs when welding Out Of position or in confined places Al-
ways wear safety glasses with side shields when in a welding area
6 g Connect the work cable to the work as close to the welding area as practical. Work cables connected to the building framework
or other locations away from the welding area increase the possibility Of the welding current passing through lifting chains,
crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until they fail
6 h Also see item 1 c
6.1. Read and follow NFPA 51B "Standard for Fire Prevention During Welding, Cutting and Other Hot Work", available from NFPA, 1

6 j DO not use a welding power source for pipe thawing
