Resumen |
Monitoring of exposure to 1,6-hexamethylene (HDI) monomers and HDI polyisocyanates from spray painting and related activities was conducted by taking 562 air samples from 60 workplaces in Oregon, USA, from 1980-1990. A high number of the samples (42%) exceeded the Oregon permissible exposure limit (PEL) of 1mg/m3 for HDI polyisocyanates. Spray finishing operations were divided into three categories: continuous industrial spraying, auto body repair shops, and intermittent spray operations of large objects. In all the surveys, the ventilation facilities and personal protective equipment were evaluated. The exposure levels were related to the HDI polymer content of the paint, types of spray guns used, ventilation facilities, and personal work practices. The impact of the Oregon PEL on the use of personal protective equipment is discussed. |
