Principle Routes of Exposure

Inhalation Ingestion Skin absorption Eye Contact: • Moderate eye irritation Skin Contact: • Causes skin irritation. • May cause sensitization by skin contact. Ingestion: • Irritation of the mouth, throat, and stomach. Inhalation: • Causes respiratory tract irritation. • Isocyanates vapors and mists at concentrations greater than the TLV can irritate the respiratory system causing runny nose, sore throat, coughing and shortness of breath. Persons with pre-existing, non-specific bronchial hyperactivity can respond to concentrations below the TLV with symptoms as well as an asthma attack. • Individuals with lung or breathing problems or prior reaction to isocyanates must not be exposed to vapor or spray mist. Target Organ and Other Health Effects: • Liver injury may occur. • Causes headache, drowsiness or other effects to the central nervous system. This product contains ingredients that may contribute to the following potential chronic health effects: • As a result of a previous exposure or a large single dose certain individuals will develop isocyanate sensitization (chemical asthma) which will cause them to react to subsequent exposures to isocyanates below the TLV. Symptoms of wheezing, cough, shortness of breath or asthma attack. Individuals may develop lung sensitivity which may persist for long periods. May cause lung damage or impairment. Sensitization may be temporary or permanent. • Overexposures may cause certain individuals to develop isocyanate sensitization which causes a reaction in isocyanates below the TLV. • Possible sensitization.
