SECTION 2: Hazards identification

Emergency Overview Appearance Physical state Liquid. Color Black Odor Solvent ® ™ Trademark of The Dow Chemical Company ("Dow") or an affiliated Hazard Summary DANGER!! Extremely flammable liquid and vapor - Vapor may cause flash fire. Causes eye irritation. May cause allergic skin reaction. May cause allergic respiratory reaction. May cause skin irritation. May be harmful if inhaled. May cause central nervous system effects; may cause respiratory tract irritation. May be harmful if swallowed. Vapor explosion hazard. Vapors may travel a long distance; ignition and/or flash back may occur. Evacuate area. Keep upwind of spill. Stay out of low areas. Warn public of downwind explosion hazard. Eliminate ignition sources.

Potential health effects

Eyes: May cause severe eye irritation. May cause severe corneal injury. Vapor may cause eye irritation experienced as mild discomfort and redness. Skin: Brief contact may cause slight skin irritation with local redness. Prolonged contact may cause moderate skin irritation with local redness. Repeated contact may cause severe skin irritation with local redness and discomfort. May cause drying and flaking of the skin. Prolonged skin contact is unlikely to result in absorption of harmful amounts. A component in this mixture has been shown to be a skin sensitizer. Once an individual is sensitized, reexposure to very small amounts of vapor, mist or liquid isophorone diisocyanate may cause an allergic skin reaction. Animal studies have shown that skin contact with isocyanates may play a role in respiratory sensitization. Inhalation: Vapor concentrations are attainable which could be hazardous on single exposure. May cause respiratory irritation and central nervous system depression. Symptoms may include headache, dizziness and drowsiness, progressing to incoordination and unconsciousness. May cause nausea and vomiting. For the minor component(s): Excessive exposure may cause irritation to upper respiratory tract (nose and throat) and lungs. May cause pulmonary edema (fluid in the lungs.) Effects may be delayed. Decreased lung function has been associated with overexposure to isocyanates. This material contains mineral and/or inorganic fillers. There is essentially no potential for inhalation exposure to these fillers incidental to industrial handling due to the physical state. A component in this mixture may cause an allergic respiratory response. Reexposure to extremely low isocyanate concentrations may cause allergic respiratory reactions in individuals already sensitized. Asthma-like symptoms may include coughing, difficult breathing and a feeling of tightness in the chest. Occasionally, breathing difficulties may be life threatening. Ingestion: Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal handling operations are not likely to cause injury; however, swallowing larger amounts may cause injury. Based on physical properties, not likely to be an aspiration hazard. Chronic Exposure: Contains component(s) which have been reported to cause effects on the following organs in animals: Liver. Respiratory tract. Tissue injury in the upper respiratory tract and lungs has been observed in laboratory animals after repeated excessive exposures to MDI/polymeric MDI aerosols. Methyl ethyl ketone has caused liver effects in laboratory animals exposed by inhalation to high concentrations. Methyl ethyl ketone is probably not neurotoxic in itself but it potentiates the neurotoxicity of methyl-n- butyl ketone and n-hexane. Contains component(s) which did not cause birth defects in animals; other fetal effects occurred only at doses toxic to the mother. Lung tumors have been observed in laboratory animals exposed to respirable 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.
