6 Many ofthe substances in welding smoke, such as chromium, nickel, arsenic,asbestos, manganese, silica, beryllium, cadmium, nitrogen oxides,phosgene,acrolein, fluorine compounds, carbon monoxide, cobalt, copper, lead, ozone,selenium, and zinc can be extremely , welding fumes and gases come from:- base material being welded or the fi ller material that is used;JSA No: JSAB uilder Sample Library - 4 (short) | Electric Arc Welding3 of 4- coatings and paints on the metal being welded, or coatings covering theelectrode;- shielding gases supplied from cylinders;The health effects of welding exposures are difficult to list, because thefumes may contain so many different substances that are known to beharmful (depending on the factors listed above).
