setting flammable materials on fire. Therefore, welding should not be done in
areas containing flammable gases, vapors, liquids or dusty locations where
explosions are a possibility. Metals with plating, coatings or paint that come
near the region of the arc may give off smoke and fumes during welding.
These fumes may pose a health hazard to the lungs, therefore an exhaust
hood or booth should be used to remove fumes from the area. When welding
in confined spaces, such as inside tanks, large containers or even
compartments of a ship, toxic fumes may gather. Also, in an enclosed room,
breathable oxygen can be replaced by shielding gases used for welding or
purging. Care must be taken to ensure enough clean air for breathing. In
many companies, it is routine to provide welders with air masks or self-
contained breathing equipment.
Q: How should an operator dress for optimum safety?
A: Gloves and clothing should be flame-resistant. Clothing made from a
dark-colored, tightly woven material is best suited for welding. Gauntlet-type
leather gloves should be worn to protect the hands and wrists. Shirt collars
and shirt cuffs should be buttoned, and open front pockets are not advisable
as they may catch sparks. Also, operators should never store matches or
lighters in their pockets. Pants cuffs are not recommended, as they will also
catch sparks. Tennis shoes do not qualify as adequate foot protection. High-
top leather shoes or boots are absolutely necessary.
