Isocyanate

This report by the Berufsgenossenschaften's Institute for Occupational Safety (BIA), contains substance and exposure data on the isocyanates groups of hazardous substances. This data may be used in prevention work and in processing reported occupational diseases. Using the available data, the 90"t"h percentile of the evaluation indices was produced for diisocyanate monomer mixtures for fields of work and processes with different levels of exposure. The result is an analysis of the current situation which aims to show any areas where exposure levels are particularly high. The results show that the following fields of work generally fall far below the limit values: surface coating, gluing, processing synthetic foam, assembly, insulating and packing foams. A higher level of exposure was established for the following areas: cavity insulation, mould foaming and block foaming, presses, casters and extruders for synthetics. Timewise, no general trend can be established for peak exposure levels; in the two periods under comparison there are both rises and falls according to sector, with the latter being more common.
