5.a. Welding may produce fumes and gases

 

the following equipment:

 

 

 

 

 

 

hazardous to health. Avoid breathing these

 

• Semiautomatic DC Constant Voltage (Wire) Welder.

 

 

 

 

 

 

fumes and gases. When welding, keep

 

• DC Manual (Stick) Welder.

 

 

 

 

 

 

your head out of the fume. Use enough

 

• AC Welder with Reduced Voltage Control.

 

 

 

 

 

 

ventilation and/or exhaust at the arc to keep

3.c. In semiautomatic or automatic wire welding, the electrode,

When

 

 

 

 

 

welding with electrodes which require special

 

electrode reel, welding head, nozzle or semiautomatic

cadmium plated steel and other metals or coatings

 

 

 

 

 

which produce highly toxic fumes, keep exposure as

 

connection with the metal being welded. The connection

 

 

 

 

 

low as possible and below Threshold Limit Values (TLV)

 

should be as close as possible to the area being welded.

3.g. Never dip the electrode in water for cooling.

 

 

 

 

 

 

exposure level should be checked upon installation and

 

 

 

 

 

 

periodically thereafter to be certain it is within applicable

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 manufacturerʼs instructions for this

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

equipment and the consumables to be used, including the

 

 

 

 

 

 

 

 

 

material safety data sheet (MSDS) and follow your

 

 

 

 

 

 

 

 

 

employerʼs safety practices. MSDS forms are available from

 

 

 

 

 

 

 

 

 

your welding distributor or from the manufacturer.
