FUMES AND GASES
Fumes and gases, can cause discomfort or harm, particularly in
confined spaces. Do not breathe fumes and gases. Shielding gases
can cause asphyxiation. Therefore:
1. Always provide adequate ventilation in the work area by natural or mechanical means.
Do not weld, cut or gouge on materials such as galvanised steel, stainless steel, copper,
zinc, lead beryllium or cadmium unless positive mechanical ventilation is provided. Do
not breathe in the fumes from these materials.
2. Do not operate near degreasing and spraying operations. The heat or arc can react with
chlorinated hydrocarbon vapours to form phosgene, a highly toxic gas and other irritant
gases.
3. If you develop momentary eye, nose or throat irritation while operating, this is an
indication that the ventilation is not adequate. Stop work and take the necessary steps to
improve ventilation in the work area. Do not continue to operate if physical discomfort
persists.
4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for specific ventilation
recommendations.
5. WARNING: This product when used for welding or cutting, produces fumes or gases that
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.
Sudden rupture of cylinder valve or relief device can injure or kill.
Therefore:
1. 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 the manufacturer's operating instructions for
mounting a regulator to a compressed gas cylinder.
2. Always secure cylinders in an upright position, by chain or strap, to suitable hand trucks,
undercarriages, benches, wall, post or racks. Never secure cylinders to work tables or
fixtures where they may become part of an electrical circuit.
3. When not in use, keep cylinder valves closed. Have valve protection cap in place if
regulator is not connected. Secure and move cylinders by using suitable hand trucks.
4. Locate cylinders away from heat, sparks and flames. Never strike an arc on a cylinder.
5. For additional information, refer to CGA Standard P-1, "Precautions for Safe Handling of
Compressed Gases in Cylinders", which is available from Compressed Gas Association,
