Sensitization
Assessment of sensitization: Sensitization after skin contact possible. The substance may cause
sensitization of the respiratory tract. As a result of previous repeated overexposures or a single large
dose, certain individuals will develop isocyanate sensitization (chemical asthma) which will cause
them to react to a later exposure to isocyanate at levels well below the PEL/TLV. These symptoms,
which include chest tightness, wheezing, cough, shortness of breath, or asthmatic attack, could be
immediate or delayed up to several hours after exposure. Similar to many non-specific asthmatic
responses, there are reports that once sensitized an individual can experience these symptoms upon
exposure to dust, cold air, or other irritants. This increased lung sensitivity can persist for weeks and
in severe cases for several years. Chronic overexposure to isocyanates has also been reported to
cause lung damage, including a decrease in lung function, which may be permanent. Prolonged
contact can cause reddening, swelling, rash, scaling, or blistering. In those who have developed a
skin sensitization, these symptoms can develop as a result of contact with very small amounts of
liquid material, or even as a result of vapour-only exposure. Animal tests indicate that skin contact
may play a role in causing respiratory sensitization.

Symptoms of Exposure
The most important known symptoms and effects are described in the labelling (see section 2)
and/or in section 11., Eye irritation, skin irritation, allergic symptoms
Medical conditions aggravated by overexposure
The isocyanate component is a respiratory sensitizer. It may cause allergic reaction leading to asthma-like spasms of the bronchial tubes and difficulty in breathing. Medical supervision of all
employees who handle or come into contact with isocyanates is recommended. Contact may
aggravate pulmonary disorders. Persons with history of respiratory disease or hypersensitivity should
not be exposed to this product. Preemployment and periodic medical examinations with respiratory
function tests (FEV, FVC as a minimum) are suggested. Persons with asthmatic conditions, chronic
bronchitis, other chronic respiratory diseases, recurrent eczema or pulmonary sensitization should
be excluded from working with isocyanates. Once a person is diagnosed as having pulmonary
sensitization (allergic asthma) to isocyanates, further exposure is not recommended.
