Hazards IdentificationBack to Contents
【Ingestion】

May cause gastrointestinal irritation with nausea, vomiting and diarrhea. 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. Animals exposed to 0.48 mg/l, the lowest dose tested, died in sixteen days.
【Skin】

May cause skin irritation. The toxicological properties of this material have not been fully investigated.

【Hazards】

Vapors form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff.
