• Description:
  Isocyanates-highly reactive chemicals used widely in coatings applied to metal structures such as bridges-are potent respiratory and skin sensitizers and a leading cause of occupational asthma. Since there is no cure for isocyanate asthma, the best management for it is complete avoidance or elimination of isocyanate exposures. Currently, little is known about isocyanate exposures and the effectiveness of exposure controls at metal structure coatings sites, such as bridge painting. The research team has previously examined worker exposure from applications of other materials containing isocyanates, such as spray foam insulation. As part of this study, they measured airborne and dermal exposures to 1,6-hexamethylene diisocyanate (1,6-HDI) and its oligomers (biuret, isocyanurate and uretdione) and assessed the adequacy of existing work practices and exposure controls via urinary biomonitoring of isocyanates at the beginning and end of work shift.
