SECTION 2: Hazards identification

EMERGENCY OVERVIEW: There is evidence that dermal and respiratory sensitization can occur from prolonged exposure to the polyurethane prepolymer.

Principle Routes of Exposure

Respiratory, Ingestion, Skin, Eyes

Potential health effects

EYES: Unset resin can be an irritant if in direct contact with eyes. May cause corneal damage. SKIN: Unset resin may stick to skin and cause irritation. Prolonged contact symptons may include redness and rash. There is some evidence that respiratory sensitization can occur through repeated skin contact. INGESTION: Although unlikely, small amounts ingested are not likely to cause injury. Gastrointestinal irritation may result from swallowing large amounts. _____________________________________________________________________________________________________________ INHALATION: At room temperatures vapors are minimal due to low volatility. At temperatures higher than 120 oF isocyanate containing fumes may be generated. Low concentrations may cause asthmatic symptoms in hypersensitive people. Excess exposure may cause irritation to the upper respiratory tract and lungs, also may cause pulmonary edema

Acute Health Hazards

Decreased lung function has been associated with overexposure to isocyanates

Health hazards

Tissue injury in the upper respiratory tract and lungs has been observed in laboratory animals after repeated excessive exposure to MDI/Polymeric MDI aersols

Medical Conditions Generally Aggravated by Exposure

Existing respiratory problems may be aggravated by prolonged exposure to this material. CARCINOGENICITY: Industrial experience in humans has not shown any links between exposure to MDI based products andcancer development. SECTION 2 NOTES:
