Health Effects
Enter text or highlight term...
Warnings: Caution: Keep out of reach of children. Extremely Flammable.
Acute Health Effects: From MSDS EYE: May cause moderate eye irritation. May cause very slight transient (temporary) corneal injury. SKIN: Prolonged or repeated exposure may cause slight skin irritation. May cause allergic skin reaction in susceptible individuals. Animal studies have shown that skin contact with isocyanates may play a role in respiratory sensitization. May stain skin. A single prolonged exposure is not likely to result in the material being absorbed in harmful amounts. INGESTION: Single dose oral toxicity is considered to be low. No hazards anticipated from swallowing small amounts incidental to normal handling operations. INHALATION: At room temperature, PMDI vapors are minimal due to low vapor pressure. However, certain operations may generate vapor or aerosol concentrations sufficient to cause irritation or other adverse effects. Excessive exposure may cause irritation to upper respiratory tract and lungs, and pulmonary edema (fluid in the lungs). May cause respiratory sensitization in susceptible individuals. MDI concentrations below the exposure guidelines may cause allergic respiratory reactions in individuals already sensitized. Symptoms may include coughing, difficult breathing and a feeling of tightness in the chest. Effects may be delayed. Decreased lung function has been associated with overexposure to isocyanates. In confined or poorly ventilated areas, propane and isobutane vapors can readily accumulate and can cause unconsciousness and death due to displacement of oxygen (simple asphyxia). Excessive exposure may increase sensitivity to epinephrine and increase myocardial irritability (irregular heartbeats). Signs and symptoms of excessive exposure may be central nervous system effects. At air concentrations < 1000 ppm, propane exerts very little physiological action; at 100,000 ppm and above it may produce dizziness or other central nervous system effects. Signs and symptoms of central nervous system depression, in order of increasing exposure, are headache, dizziness, drowsiness, and unconsciousness, even death.
Chronic Health Effects: From MSDS None given
Carcinogenicity: From MSDS Lung tumors have been observed in laboratory animals exposed to 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 expecte
