Fire extinguisher powders

Sodium bicarbonate inhibits the chain of reactions which occur during combustion. The surfaces of its crystals trap the free radicals and complex intermediary products generated by combustion, thus halting the chain reaction.

Its extinguishing action is also assisted by the endothermic and smothering characteristics of the reaction which occurs when sodium bicarbonate decomposes, releasing carbon dioxide in contact with the seat of the fire.

Fighting liquid and gas fires
Sodium bicarbonate-based fire extinguisher powders are class BC powders. These are particularly suitable for extinguishing burning liquids (class B : paraffin, petrol, alcohol, paint, etc.) and gas (class C : methane, propane, benzene, etc.).
Our fire extinguisher powders, BI-EX ®, are used specifically for the car fire extinguishers which must be carried by law in some countries.
