F. Julier et al., MEASUREMENT OF FIBROUS DUST CONCENTRATIONS WHEN HANDLING MINERAL-WOOLINSULATIONS ON INDUSTRIAL BUILDING SITES, Staub, Reihhaltung der Luft, 53(6), 1993, pp. 245-250
The 500 000 fibres/m3 TRK-value for man-made-mineral fibres, set by th
e ''Ausschuss fur Gefahrstoffe'', has presented a new criteria for min
eral- and glass-wool insulation exposure assessments. Sampling data in
dicates that the TRK-value is not exceeded during installation work, h
owever concentrations above this value should be expected during remov
