Working Safely with Isocyanates

http:​//www.cdph.ca.gov/programs/hesis/Pages/Isocyanates.aspx

Many workers - especially in auto body repair, foam manufacturing, and some types of construction - are exposed to isocyanates, a component of many polyurethane systems.

Worker in protective suit, full-face respirator and gloves spraying polyurethaneBreathing in isocyanates, or even getting these chemicals on skin, can cause asthma. Continued exposure to isocyanates can make the asthma worse. Once asthma starts it can be lifelong, and asthma attacks at their worst may be life-threatening.

Isocyanates are used in automotive paint, spray-on truck bed linings, adhesives,  orthopedic casts, shipping foams, polyurethane cushioning, industrial coatings, and in spray polyurethane foam (SPF) used to insulate walls and roofs.

OHB materials and resources provide information on health hazards from isocyanates and ways to minimize workplace exposures.
