| Resumen |
This note reproduces, as a guide, the list of threshold limit values (TLVs, expressed in ppm or mg/m3) adopted by the American Conference of Governmental Industrial Hygienists in 1973 for over 500 hazardous substances which may be absorbed in the form of dust or fume in workroom air. A preface discusses briefly chemical contaminants, advantages and disadvantages of ceiling as against time-weighted average limits, nuisance particulates as opposed to fibrogenic dusts, short-term limits, biologic limit values, asphyxiants, etc. TLVs for mineral dusts, notice of intended changes in the list (especially carcinogens), mixtures, some nuisance particulates, some inert gases and vapours (simple asphyxiants), etc. are appended. Lower TLVs for some of these substances are recommended for the U.K. (in particular for asbestos and vinyl chloride). |
