isocyanate
exposure testing

Isocyanytes are widely used in the manufacture of flexible and rigid foams, fibers, coatings such as paints and varnishes, and elastomers, and are increasingly used in the automobile industry, autobody repair and for construction insulation materials.

The health effects of isocyanate exposure can include irritation of skin and mucous membranes, chest tightness, and difficulty breathing. Isocyanates are actually one of the leading causes of occupational asthma in the UK and are also known for there potential to cause cancer.

As respiratory sensitisers, exposures to isocyanates should be kept as low as reasonably practicable and this often requires the use of respiratory protective equipment (RPE).

Actions and advice

The starting point of a workplace exposure assessment in relation to Isocyanates is to review the product data sheet to identify the specific Isocyanate that is in use. 

Once this has been identified an assessment of exposure levels should be conducted by implementing an exposure testing regime. These exposure levels should then be compared with the workplace exposure levels (WEL's) as defined by the Health & Safety Executive. Any actions should then be taken to either reduce or control exposure as part of an ongoing monitoring regime.
