Fire Hazards
Special Hazards of Combustion Products: Produces toxic fumes of phosgene and HCl. (USCG, 1999)
· Combustible material: may burn but does not ignite readily.
Health Hazards
Extremely destructive to the eyes, nose, throat, and upper respiratory tract. May be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. (USCG, 1999)
· TOXIC and/or CORROSIVE; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death.
Hazards Summary
