Isocyanate Detection

CAS Number: 822-06-0 (HDI)

Dangers

While the use of isocyanates is common, worker exposure to isocyanates can be hazardous. Toluene Diisocyanates (TDI) and Methylene Diphenyl Diisocyanate (MDI) detection capabilities should be in place whenever these chemicals are in use. Exposure to isocyanates can cause occupational asthma, irritation of the skin, eyes, nose and throat, and cancer. Deaths have occurred from high dose exposures to isocyanates. Respiratory illnesses also can be caused by isocyanate exposure to the skin.

Where are they found

Isocyanates are widely used in industry. The two most common forms are Toluene Diisocyanates (TDI) and Methylene Diphenyl Diisocyanate (MDI), which are used primarily in polyurethane manufacturing for products such as insulation, mattresses, furniture and car seats. They are also used in spray-on protective coatings, adhesives, paints, and varnishes.
