Abstract
Results of MMMF measurements in the Danish user industry are reported. Results of a published Swedish report which also mentions irritation effects are quoted. The Danish survey was carried out using the same sampling methods as used in the JEMRB dust survey in the European manufacturing industry. Some other methods were added. Fibre levels during different work situations and not long-term exposure levels were determined. Fibre levels varied from less than 0.05 to over 3 f/cm 3 . Fifty per cent of all fibres had diameters less than 1.0 μm. The greatest fibre levels were found during technical insulation and insulation in existing buildings. The concentration and fibre geometry of coarse fibres was determined. Work with MMMF manufactured in 1951 gave high fibre levels with diameter distributions being comparable with the ones found for modern MMMF.This publication has 0 references indexed in Scilit:
