May form explosive peroxides on long standing or after exposure to air or light. Dry chemical, foam or carbon dioxide. Treat as a flammable gas in a fire situation. Water spray may be used to keep fire exposed containers cool. This highly flammable liquid must be kept from sparks, open flame, hot surfaces, and all sources of heat and ignition.
Vapors can flow along surfaces to distant ignition source and flash back.
Stable under ordinary conditions of use and storage. Heat, light, and long standing contribute to instability. Reacts with air to form explosive peroxides. Toxic gases and vapors such as carbon monoxide may be released in a fire. Contain and recover liquid when possible.
