Abstract Earlier studies showed that the thermal degradation of polyurethane-based car body paints could generate isocyanates, which are potentially harmful substances. An in situ sampling system was devised for the air sampling of isocyanates produced during the thermal degradation process. However under field conditions, various factors can affect the sampling efficiency. The purpose of this study was to validate the sampling technique under actual working conditions and to establish an indicator for evaluating the overall exposure of workers to the isocyanates generated by the thermal degradation of paints. Measurements carried out in three car body repair shops confirmed the reliability of the method.
