The use of isocyanate paints in auto refinishing--a survey of isocyanate exposures and related work practices in South Australia.

A survey of 45 crash repair workshops where two-pack polyurethane spray paints are used has been carried out. Painters were interviewed using a combined health-work practice questionnaire. Monitoring for airborne isocyanate was undertaken in 14 spray shops. Health data from the questionnaire were compared with corresponding data for control groups of mechanics and industrial spray painters, not exposed to isocyanates. Compared with the other two groups, the isocyanate spray painters generally reported more respiratory and skin problems. Airborne isocyanate concentrations associated with various operations were monitored with both impinger and paper tape methods. A direct comparison of the two methods is presented.
