| Abstract |
Results of a dust sampling at this workplace to estimate the overall concentration, the particle size distribution and the chemical composition of dust released during cutting of metal plates of various thicknesses and alloying constituents. The chief components of the dust were metal oxides, the most toxic being chromium and manganese oxides. Since 94-98% of the particles were <5µm, local exhaust systems must be fitted with appropriate dust collection equipment. (An article by Kozlov V.A. in the same issue (p.51-52) on the choice of dust collectors for these machines evaluates 12 collectors of Soviet manufacture.) |
