SECTION 2: Hazards identification

OSHA Hazards Emergency Overview Color: Black Physical State: Paste Odor: Odorless Hazards of product: WARNING! May cause allergic skin and respiratory reaction. May cause eye irritation. Isolate area. Keep upwind of spill. OSHA Hazard Communication Standard This product is a "Hazardous Chemical" as defined by the OSHA Hazard Communication Standard, 29 CFR 1910.1200.

Potential health effects

Eye Contact: May cause eye irritation. Skin Contact: Prolonged contact may cause slight skin irritation with local redness. Material may stick to skin causing irritation upon removal. May stain skin. Skin Absorption: Prolonged skin contact is unlikely to result in absorption of harmful amounts. ®(TM)*Trademark of The Dow Chemical Company ("Dow") or an affiliated company of Dow Skin Sensitization: A component in this mixture has been shown to be a skin sensitizer. Animal studies have shown that skin contact with isocyanates may play a role in respiratory sensitization. Inhalation: At room temperature, exposure to vapor is minimal due to low volatility. Vapor from heated material may cause respiratory irritation and other effects. For the minor component(s): Methylene diphenyl diisocyanate (MDI). Excessive exposure may cause irritation to upper respiratory tract (nose and throat) and lungs. May cause pulmonary edema (fluid in the lungs.) Decreased lung function has been associated with overexposure to isocyanates. Effects may be delayed. 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. Respiratory Sensitization: A component in this mixture may cause an allergic respiratory response. MDI concentrations below the exposure guidelines 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. May cause nausea and vomiting. May cause abdominal discomfort or diarrhea.

Aspiration hazard

Based on physical properties, not likely to be an aspiration hazard Effects of Repeated Exposure: Contains component(s) which have been reported to cause effects on the following organs in animals: Liver. Kidney. Tissue injury in the upper respiratory tract and lungs has been observed in laboratory animals after repeated excessive exposures to MDI/polymeric MDI aerosols.

Cancer information

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. Birth Defects/Developmental Effects: Contains component(s) which did not cause birth defects in animals; other fetal effects occurred only at doses toxic to the mother. In laboratory animals, MDI/polymeric MDI did not cause birth defects; other fetal effects occurred only at high doses which were toxic to the mother. Reproductive Effects For the phthalate ester(s) In laboratory animals, excessive doses toxic to the parent animals caused decreased weight and survival of offspring.
