Suitable (and unsuitable) extinguishing media Suitable extinguishing media Water spray. Carbon dioxide. Dry powder. Alcohol-resistant foam. Unsuitable extinguishing media Do not use a heavy water stream. 5.2. Specific hazards arising from the chemical Fire hazard May form flammable vapour-air mixtures. May decompose violently at elevated temperatures or in a fire. Burns vigorously. Insoluble in water. Contact with alkalis or acids may cause dangerous decomposition. The products of combustion or self-accelerating decomposition may be toxic by inhalation. Will float and can be reignited on water surface. Explosion hazard Vapours may form explosive mixture with air. Reactivity in case of fire Decomposition products may be a hazard to health. Hazardous decomposition products in case of fire Formation of toxic gases is possible during heating or in case of fire. Corrosive vapours. Thermal decomposition can lead to the release of irritating gases and vapours. 5.3. Special protective equipment and precautions for fire-fighters Firefighting instructions Use water spray or fog for cooling exposed containers. Exercise caution when fighting any chemical fire. Prevent fire fighting water from entering the environment. Protection during firefighting Self-contained breathing apparatus. Do not enter fire area without proper protective equipment, including respiratory protection. SECTION 6: Accidental release measures 6.1. Personal precautions, protective equipment and emergency procedures General measures Spilled material may present a slipping hazard. 6.1.1. For non-emergency personnel Protective equipment Wear recommended personal protective equipment. Emergency procedures Evacuate unnecessary personnel. No flames, no sparks. Eliminate all sources of ignition. Explosive vapour/air mixtures may be formed. 6.1.2. For emergency responders Protective equipment Use personal protective equipment as required. Equip cleanup crew with proper protection. Emergency procedures Ventilate area. 6.2. Environmental precautions Prevent entry to sewers and public waters. Notify authorities if liquid enters sewers or public waters. 6.3. Methods and material for containment and cleaning up For containment Collect spillage.
