Welding fumes and gases can displace air and lower the oxygen level causing injury or death, be
sure the breathing air is safe
Do not weld in locations near degreasing, cleaning, or spraying operations, the heat and rays of
the arc can react with vapors resulting in highly toxic or irritating gases
Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, coatings and
metals containing these elements can generate toxic fumes when heated to welding
temperature
