Fire Extinguishing Agents

Fire extinguishing agents have a history of more than 90 years. The first extinguishing powders were produced on base of sodium bicarbonate. Yet they are only suitable for the fighting of burning liquids (class B) and gases (class C). In case of fires of solid matters burning with incandescence, however, they fail.

Therefore the demand was to develop a multi-purpose extinguishing powder (classes ABCD) capable of fighting as well fires in which incandescent materials are involved as liquid, gas and metal fires. This was the more necessary as practical experience showed that pure liquid or gas fires seldom occur. Mostly incandescent materials are involved.

In fire class A, these liquid extinguishing agents show an extremely high extinguishing performance. The reason for this is the combination of the cooling effect of water and the barrier layer effect which arises when Pyrosal^® forms a crust of salt.

In fire class B the extinguishing agent releases a thin watery film which exhibits extreme spreading properties to cover quickly the whole burning liquid, extinguish all flames, keep oxygen off and prevents reignition.

Part of our service is that we offer our customers excellent technical advice: e.g. rapid determination of the optimal extinguishing agent for every extinguisher and type of fire, by laboratory and practice tests.

Particular attention is given to continuous quality control. Each batch is tested - starting from the raw material to the finished product - using the most modern physical and chemical test methods. The high standard and consistent quality of our products are the basis for our long-established good partnership with our customers throughout the world.
