/Threshold Limit Values/ using local exhaust or mechanical ventilation.
In confined spaces or in some circumstance, outdoors, a respirator may
be required. Additional precautions are also required when welding on
galvanized steel.
- Do not weld in locations near chlorinated hydrocabron vapors coming from
degreasing, cleaning or spraying operations. The heat and rays of the arc
can react with solvent vapors to form phosogne, 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 in-
sure 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
and follow your employer's safety practices.
- 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 areas. Avoid welding near hydraulic
lines. Have a fire extinguisher readily available.
- Where compressed gases are to be used at the job site, special precau-
tions should be used to prevent hazardous situations.
- When not welding, make certain no part of the electrode circuit is touch-
ing the work or ground. Accidental contact can cause overheating and
create a fire hazard.
- 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.
