BC and BCK powders have a very high purity due to their raw materials used.
BC extinguishing powder based on sodium bicarbonate is naturally free of heavy metals. Therefore, there is no need to fear environmental pollution from the extinguishing powder applied during extinguishing.
BCK extinguishing powder based on potassium bicarbonate has a greater and more efficient extinguishing effect than pure BC powder.
Since DIN EN 3 does not define a higher rating than 233 B for portable fire extinguishers, this important property cannot be seen directly on the extinguisher. Due to this difference in performance, especially chemical companies with plant fire brigades opt for extinguishers with BCK powder.
