| Hazards Identification | Back to Contents | 【Inhalation】
Causes respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. Can produce delayed pulmonary edema. | 【Skin】
Causes skin irritation. | 【Eyes】
Causes eye irritation. May cause chemical conjunctivitis. | 【Ingestion】
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated. | 【Hazards】
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion and poison hazard indoors, outdoors or in sewers. | 【EC Risk Phrase】
