Fire-fighting measures5.1 Extinguishing mediaSuitable extinguishing media: Alcohol-resistant foamCarbon dioxide (CO2)Dry chemicalUnsuitable extinguishing : High volume water jetmedia5.2 Special hazards arising from the substance or mixtureSpecific hazards during firefighting: Do not allow run-off from fire fighting to enter drains or watercourses.5.3 Advice for firefightersSpecial protective equipmentfor fire-fightersFurther information: Wear self contained breathing apparatus for fire fighting ifnecessary.: Collect contaminated fire extinguishing water separately. Thismust not be discharged into drains.Fire residues and contaminated fire extinguishing water mustbe disposed of in accordance with local regulations.For safety reasons in case of fire, cans should be storedseparately in closed containments.Use a water spray to cool fully closed containers.6. Accidental release measures6.1 Personal precautions, protective equipment and emergency proceduresPersonal precautions: Use personal protective equipment.Ensure adequate ventilation.Remove all sources of ignition.Evacuate personnel to safe areas.Beware of vapours accumulating to form explosiveconcentrations. Vapours can accumulate in low areas.6.2 Environmental precautionsEnvironmental precautions: Prevent product from entering drains.Prevent further leakage or spillage if safe to do so.If the product contaminates rivers and lakes or drains informrespective authorities.6.3 Methods and materials for containment and cleaning upMethods for cleaning up: Contain spillage, and then collect with non-combustibleabsorbent material, (e.g. sand, earth, diatomaceous earth,vermiculite) and place in container for disposal according tolocal / national regulations (see section 13).4 / 11
