Scope

During the process of welding, metal vapors are produced in the electric arc. As these vapors cool and solidi@, a fume is formed that may be a potential health hazard to the welder and to others working in the same area. Such fine aerosols are all irritating to the respiratory system. Yet some fumes may potentially be more dangerous than others because of the specific substances present.
