Air cleanliness requirements of workplaces - Airborne dust Jurisdiction Hungary Year 1992 Published in Hungarian Original/other title [Hungarian] Munkahelyek levegőtisztasági követelményei - Szálló porok Source Szabványbolt, Pf. 162.1431, Budapest, Hungary, 1992. 5p. Illus. 11 ref. Serial number MSZ 21461-2 Descriptors [Primary] Hungary, airborne dust, respirable dust, threshold limit values [Secondary] asbestos, chrysotile, glass fibre, limitation of exposure, man-made fibres, silica, standard, talc, total silica Subject category Chemical safety Abstract This standard specifies the maximum permissible limits of mineral dust and fibre concentrations in workplace air in Hungary. It also provides a legal definition of the particulates concerned. The basic limits are (in mg/m3): respirable dusts: 0.1 (for 100% silica), 6.0 (for silica-free dust); total dust: 8.0 (when more than 20% of respirable dust is silica), 10.0 (for silica-free dust). Intermediate concentration limits are set for dust with intermediate silica content. For fibres, limits are set in fibre/cm3 - asbestos: chrysotile (1), amphiboles (not authorised); other fibres (glass, mineral, ceramic, plastic) (1). For talc dust, the limits are: asbestos-containing (1 fibre/cm3), other respirable (2.0mg/m3), other total dust (10.0mg/m3). This standard does not apply to silica-free dust with fibrogenic, toxic, mutagenic, carcinogenic, irritative, corrosive or allergenic properties. CIS No. 93-1416 Database ID 60730
