Isocyanates are a family of highly reactive, low molecular weight chemicals. It is widely used in the production of flexible and rigid foams, fibers, coatings such as paints and varnishes, and elastomers. It is also increasingly used in the automobile industry, auto body repair and building insulation materials.
Sprayed polyurethane products containing isocyanate have been developed for a wide variety of retail, commercial and industrial uses to protect cement, wood, fiberglass, steel and aluminum, including protective coatings for truck bodies, trailers, boats, foundations and decks.
Isocyanates are strong irritants to the mucous membranes of the eyes and to the stomach, intestines and respiratory tract. Direct skin contact can also cause significant inflammation. Isocyanates may also sensitize workers, causing them to suffer severe asthma attacks if re-exposure. There is evidence that both inhalation and dermal exposures can cause sensitization. Death from severe asthma has been reported in some susceptible individuals. Employees potentially exposed to isocyanates who experience persistent or recurrent eye irritation, stuffy nose, dry or sore throat, cold-like symptoms, cough, shortness of breath, wheezing or chest tightness should see a doctor for work-related health problems.
Isocyanates are commonly found in automotive paints, foam cushions, mattresses, car seats, foam insulation, foam packaging materials, carpet fillers, polyurethane rubber, and adhesives.
Isocyanates are commonly found in paints, and nearly all motor vehicle repair shops use paints containing isocyanates. Motor vehicle paint sprayers have a 90 times greater risk of developing asthma in workers. Moreover, other workers nearby can also develop symptoms and pose a health risk. In this respect, businesses must make a risk assessment, take appropriate control measures and establish a health surveillance program. Health surveillance for isocyanates includes in-house isocyanate analysis as well as respiratory and skin control for workers.
Our organization also provides isocyanate analysis services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
