Skin Exposure to Aliphatic Polyisocyanates in the Auto Body Repair and Refinishing Industry

The latest issue of 'Annals of Occupational Hygiene' offers a qualitative
assessment of skin exposure to aliphatic polyisocyanates in the auto body
repair and refinishing industry. Although respiratory exposures have been the
primary concern with isocyanates, skin exposure also can occur and may
contribute to sensitization and asthma. Methodologies to assess isocyanate skin
exposure in the workplace are limited and skin exposure data scarce. The goals
of this study were

  • to evaluate and validate the isocyanate colorimetric indicators against a
    quantitative assay,

  • to evaluate the extent of isocyanate surface contamination and skin exposure
    among auto body shop workers and

  • to evaluate isocyanate skin exposure determinants.

This study documents extensive surface contamination and skin exposure,
including under gloves, to aliphatic polyisocyanates during painting and paint
mixing tasks in auto body shop workers. Contaminated surfaces and aerosol
deposition during spray painting may both contribute to skin exposure.
