Abstract Laboratory studies with animals exposed to high concentrations of fine fibrous dust (fibrils) derived from para-aramid fibres suggest that it may cause lung damage. A survey was undertaken in a selection of manufacturers of para-aramid-containing products to assess their 8-h time-weighted average exposure to respirable fibrils. Geometric mean concentrations for different jobs were generally low. Assuming a log-normal distribution, less than 1% of the exposure levels would be expected to exceed 0.5 fibres/mL and about 0.002% would be above 2 fibres/mL. Analysis of a selection of samples by fluorescence microscopy suggests that most of the fibrils in the majority of sites surveyed were para-aramid. At some sites a significant proportion of asbestos fibres were also found.
