Potential hazard:
Inhaling isocyanates may sensitize a person, causing an asthma-like reaction. This reaction may
occur within days of exposure or may take months or years to develop. Once sensitized, a person is
likely to experience recurring shortness of breath upon repeated exposure.
Direct skin contact with isocyanates may cause rashes, blistering and reddening of the skin.
Repeated skin contact may cause skin sensitization.
Exposure to airborne isocyanates can cause eye irritation and temporary blurred vision. Direct
contact with the eye may cause cornea damage.
How to control the hazard:
When working with isocyanates, inhalation and contact with the skin or eyes can be avoided by using
adequate personal protective equipment (PPE).
