The Fire Knock Out system automatically launches itself upon contact with fire and then fights the fire within just a few seconds.
The plastic container is filled with a special fire fighting liquid and triggering powder, to which a fast fuse is attached. As soon as the fuse comes into contact with fire, the container bursts open. As a result, for a brief moment in time, all the surrounding oxygen is depleted, causing the fire to immediately be fought.
The liquid in the extinguisher, which is transformed into tiny water droplets, cools down the seat of the fire, while the buffer compounds reduce the chance of the fire getting started again to an absolute minimum. This whole process lasts only a few seconds, and the manufacturer says the plastic debris remaining behind can easily be collected and completely recycled.
Getting close to the seat of a fire is often impossible due to the enormous heat and usually not smart anyway, as goods, which are hidden by quickly developing smoke clouds, may suddenly explode. The low weight of the FKO also allows it to be rolled or thrown into the seat of the fire from a safe distance.
The quick fuse used has a plastic outer layer and is therefore water resistant.
The FKO comes in different types and models. The most common type is based on foam and is able to fight Class A (organic solids, which tend to glow), Class B (liquids or liquifiable solids) and Class C (gasiform) fires.
The packaging is hermetically sealed against dust and moisture, limiting maintenance to periodic visual checks.
