SECTION 2: Hazards identification

EMERGENCY OVERVIEW ***: Black Liquid, with Solvent odor. Flammable liquid and vapor. May cause allergic skin reaction. May cause allergic respiratory reaction. Vapor harmful; may affect the brain or nervous system causing dizziness, headache or nausea. Causes skin and eye irritation. Causes respiratory tract irritation. EFFECTS OF OVEREXPOSURE - EYE CONTACT: Causes eye irritation. EFFECTS OF OVEREXPOSURE - SKIN CONTACT: May cause skin sensitization. May cause dermatitis. Causes skin irritation. Animal tests have indicated that respiratory sensitization can result from skin contact with certain isocyanates. 300000001198 EFFECTS OF OVEREXPOSURE - INHALATION: Possible irritation of the respiratory system can occur causing a variety of symptoms such as dryness of the throat, tightness of the chest, and shortness of breath. May cause central nervous system depression characterized by the following progressive steps: headache, dizziness, staggering gait, confusion, unconsciousness or coma. Allergic conditions can occur in certain individuals with high sensitivity to isocyanates; this may result in asthma-like symptoms. In elevated-temperature applications, product may release vapors that may produce cyanosis in the absence of sufficient ventilation or adequate respiratory protection. May cause respiratory sensitization. May cause lung damage. EFFECTS OF OVEREXPOSURE - INGESTION: Harmful if swallowed. Ingestion is not an expected route of entry in industrial or commercial uses. EFFECTS OF OVEREXPOSURE - CHRONIC HAZARDS : May cause liver or kidney damage. Repeated or prolonged solvent overexposure may result in permanent central nervous system damage. May affect the blood and blood-forming organs. Chronic skin contact may cause dermatitis. Ethylbenzene has been classified by IARC as a possible human carcinogen (Group 2B). IARC has designated trichloroethylene as Group 2A - limited evidence for carcinogenicity in humans and sufficient evidence in experimental animals. IARC has designated carbon black as Group 2B - inadequate evidence for carcinogenicity in humans, but sufficient evidence in experimental animals. 1,2 butylene oxide has been classified by IARC as a possible human carcinogen (Group 2B). The nitrogen substituted aromatic in this product gave positive results for mutagenicity in an Ames Assay study while two other mutagenicity studies proved negative.
