Extinguishing media

- Suitable: All extinguishing agents can be used (water, foam, powders, carbon dioxide, sand )

- Not suitable: None known. If there is a fire close by, use suitable extinguishing agents.

Specific hazards: On heating or during combustion: Toxic vapours are released.

Specific fire fighting methods: Usual methods for dealing with chemical fires.  Cool down the containers/equipment exposed to heat with a water spray.  

Protection of fire-fighters: Self-contained breathing apparatus.  Complete protective clothing.

Personal precautions Avoid contact with skin, eyes and respiratory system.  If spillage occurs on the public highway, indicate the danger and notify the authorities (police, fire brigade).

- Full protective clothing and equipment should be worn.

Environmental precautions: Contain the spilled material by bunding. Avoid direct discharge into drains.

Accidental release measures
