SECTION VIII
SPECIAL PROTECTION INFORMATION (See Note 1)
Respiratory Protection: Weld fume respirator or air-line respirator for confined
space or where exposures are above TLV.
Ventilation: Local Exhaust: Freely movable exhaust ducts with air flow of
100 linear ft./min.
Mechanical (General): Not applicable if local exhaust is adequate.
Eye Protection: Up to 5/32" diam., use #10 lens; for 3/16" diam.,
and larger use #12 lens.
Viewing electric arc without protection can result in severe eye damage.
Protective Gloves: Welder's protective gloves. Unprotected skin can be severely
burned by the electric arc.
Other Protective Equipment: Equipment as required by welding conditions.
Dark clothing should be worn to protect skin from electric arc burning.
SECTION IX
SPECIAL PRECAUTIONS (See Note 1)
Other Precautions: Arc and sparks could be source of ignition of combustible
products.
Nearby personnel should be warned against direct viewing of welding arc without
the proper eye protection.
NOTE 1: For additional information, see American
National Standard Safety in Welding & Cutting Z49.1-1967
(American Welding Society Publication Z49.1-1967).
NOTE 2: State of California knows that welding
produces compounds that can cause cancer, birth defects or other
reproductive harm.
