SECTION 2: Hazards identification

Acute Effects (Short Term): Eye: Product may be irritating to eyes if in direct contact. Skin: Prolonged or repeated exposure may cause skin irritation. Acute skin contact – Isocyanates reacts with skin protein & moisture & cause irritation which may include reddening, swelling, rash, scaling or blistering. Inhalation: Polymeric Diisocyanate vapors at concentrations above the TLV can irritate the mucous membranes in the respiratory tract (nose, throat, lungs) causing a runny nose, sore throat, coughing, chest discomfort, shortness of breathe and reduced lung function. Persons with pre-existing, nonspecific bronchial hyper reactivity can respond to concentrations below TLV with similar symptoms as well as asthma attack.

Medical Conditions Generally Aggravated by Exposure

Pre-existing eye, skin & respiratory disorders may be aggravated by exposure to fumes or vapors of this product at elevated temperatures. Existing allergies may increase the chance of developing increased allergy symptoms. Asthma, other respiratory disorders (bronchitis, emphysema, bronchial hyper reactivity), skin allergies, eczema. Other Health Hazards: Lung tumors have been observed in laboratory animals exposed to aerosol droplets of MDI/ Polymeric MDI (6 mg/m3) for their lifetime. Tumors occurred concurrently with respiratory irritation and lung injury. Current exposure guidelines are expected to protect against these effects reported for MDI.
