SAFETY SUMMARY
Always use a shield with the proper filter and cover plates to protect your
eyes from sparks as well as the welding arc radiation when observing open
arc welding. Head shield and filter lens should comply with ANSI Z87. I
standards.
Use suitable clothing made from durable flame-resistant material to protect
your skin and that of your helpers from the welding arc radiation.
Protect other nearby personnel with suitable, non-flammable screening
and/or warn them not to watch the arc nor expose themselves to the arc
radiation or to hot spatter or metal.
Welding may produce hazardous fumes and gases. Avoid breathing those
fumes and gases. When welding, keep your head out of the fume. Use
enough ventilation and/or exhaust in the arc zone to keep fumes and gases
away from the breathing zone. When welding with electrodes that require
special ventilation such as stainless or hard facing (see instructions on
container or MSDS) or on lead or cadmium plated steel and other metals or
coatings which produce highly toxic fumes, keep exposure as low as possible
and below Threshold Limit Values (TLV) using local exhaust or mechanical
ventilation. In confined spaces or under some circumstances outdoors, a
respirator may be required. Additional precautions are also required when
welding on galvanized steel.
Do not weld in locations near chlorinated hydrocarbon vapors coming from
degreasing, cleaning or spraying operations. The heat and radiation from the
arc can react with solvent vapors to form phosgene, a highly toxic gas, and
other irritating products.
Shielding gases used for arc welding can displace air and cause injury or
death. Always use enough ventilation, especially in confined areas, to ensure
breathing air is safe.
Read and understand the manufacturer’s instructions for this equipment and
the consumables to be used, including the material safety data sheet (MSDS)
and follow your employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.
Remove any fire hazard 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 in adjacent areas. Avoid welding near hydraulic lines.
Always have a fire extinguisher readily available.
When compressed gases are to be used at the job site, special precautions
