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 within applicable OSHA PEL and
ACGIH TLV limits using local exhaust or

some circumstances, outdoors, a respirator may
be required. Additional precautions are also
required when welding on galvanized steel.
