| Hazards Identification | Back to Contents | 【Inhalation】
May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. | 【Skin】
Causes mild skin irritation. | 【Eyes】
May cause eye irritation. | 【Ingestion】
The toxicological properties of this substance have not been fully investigated. May be harmful if swallowed. | 【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 hazard indoors, outdoors or in sewers. | 【EC Risk Phrase】
