Foam Fire Extinguisher

A foam fire extinguisher can even put out burning liquids.

What to use a foam extinguisher on – and what not

A foam fire extinguisher is suitable for class A and B fires, i.e. solid materials and flammable liquids.

Do not try to use it on liquids that mix with water – the foam will tend to dissolve.

Likewise, foam will not put out burning gases.

How does it work?

The filling of this fire extinguisher is water-based and contains a foaming agent. As the mixture leaves the nozzle it foams up, creating an extinguishing mixture with excellent properties. The foam covers the seat of the fire, cutting off the oxygen and cooling everything effectively – the flames do not stand a chance.

What to watch out for

As for liquids, a foam fire extinguisher can only be used on those that do not mix with water (oil, diesel, petrol, wax, etc.). When extinguishing liquids, do not spray the foam directly into the liquid – start around the edges so that the foam gradually covers the liquid and the burning liquid is not scattered.

A foam fire extinguisher must not be used on live equipment or on light and alkali metals.

Foam fire extinguisher – class F

There is a special foam fire extinguisher designed specifically for fighting burning animal and vegetable fats and oils. It is designed so that the burning oil does not splash, and it forms a layer on the surface that stops the fire and prevents spontaneous re-ignition. This makes it an indispensable safety tool for kitchens and other food operations where there is a risk of fats igniting.
