scope:

Specifies a procedure for personal sampling of airborne particles in welding and allied processes. The procedure describes determination of personal exposure to welding fume and other airborne particles generated by welding related operations. The general background level of airborne particles in the workplace atmosphere influences personal exposure, and therefore the role of fixed point sampling is also considered. Guidance is given on the use of chemical analysis to determine personal exposure to specific chemical agents present in welding fume, but analytical methods are not described.
