Fire-fighting measures

Extinguishing media-

Suitable extinguishing media:       

The product is flammable. Extinguish with alcohol-resistant foam, carbon dioxide, dry powder or water fog. Use fire-extinguishing media suitable for the surrounding fire.

Unsuitable extinguishing media:

Do not use water jet as an extinguisher, as this will spread the fire.

Special hazards arising from the substance or mixture-

Specific hazards       :

Containers can burst violently or explode when heated, due to excessive pressure build-up. Flammable liquid and vapour.  Vapours may be ignited by a spark, a hot surface or an ember.  Vapours may form explosive mixtures with air. Fire-water run-off in sewers may create fire or explosion hazard.

Hazardous combustion products:

Thermal decomposition or combustion products may include the following substances: harmful gases or vapours.

Advice for firefighters:

Protective actions during firefighting

Protective actions during firefighting:

Avoid breathing fire gases or vapours. Evacuate area. Cool containers exposed to heat with water spray and remove them from the fire area if it can be done without risk. Cool containers exposed to flames with water until well after the fire is out. If a leak or spill has not ignited, use water spray to disperse vapours and protect men stopping the leak. Control run-off water by containing and keeping it out of sewers and watercourses. If risk of water pollution occurs, notify appropriate authorities.

Special protective equipment for firefighters:

Wear positive-pressure self-contained breathing apparatus (SCBA) and appropriate protective clothing. Firefighter's clothing conforming to European standard EN469 (including helmets, protective boots and gloves) will provide a basic level of protection for chemical incidents.
