| Hazards Identification | Back to Contents | 【Ingestion】
May cause digestive tract disturbances. The toxicological properties of this substance have not been fully investigated. | 【Inhalation】
May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. | 【Skin】
May cause skin irritation. The toxicological properties of this material have not been fully investigated. | 【Eyes】
May cause eye irritation. The toxicological properties of this material 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】
