Compressed air foam - extinguishing effects for class A fires

Compressed air foam develops its high extinguishing efficiency through various extinguishing effects. This video shows an animation of extinguishing effects of compressed air foam on class A fires. In general, several extinguishing effects kick in when fighting fires with extinguishing foam: • Covering effect • Separation effect • Cooling effect • Isolation effect In the case of the covering effect extinguishing foam - compressed air foam in this video - is applied to a burning material class A. The compressed air foam on the material´s surface prevents pyrolysis gases from escaping. In case of a class A fire flammable gases are released from the material by the intense heat and these gases ignite. A top layer consisting of compressed air foam prevents these gases from escaping. Another effect is the separation effect. Extinguishing foam or compressed air foam which is applied to a burning material shields it from the oxygen in the air. However, oxygen is necessary for combustion. Without oxygen the fire is suffocated. Reignition is impossible as long as a layer of compressed air foam separates the material from oxygen. Compressed air foam - like any other extinguishing foam - contains water. This leads to a cooling effect in class A fires. Compressed air foam adhering to the burning material heats up, i.e. thermal energy is transferred from the burning material to the compressed air foam. As a result the temperature of the material decreases. If extinguishing foam / compressed air foam reaches a temperature of more than 100 degrees Celsius the water it contains evaporates. The fourth effect is an isolation effect. Extinguishing foam / compressed air foam adhering to walls, ceilings and objects acts as an isolation layer. No more heat can be released to the environment from the extremely heated surfaces. On the one hand, this makes the operation for firefighters much safer during interior attacks. On the other hand, compressed air foam protects combustible surfaces from ignition by heat radiation.

Prerequisite for all these extinguishing effects of extinguishing foam and in particular compressed air foam is a good adhesion. Wet extinguishing foam or compressed air foam which flows down at the burning material like water can never achieve the above mentioned extinguishing effects. Schmitz One Seven GmbH has developed compressed air foam systems under the proprietary brand name “One Seven” which produce an extremely efficient compressed air foam. In addition to excellent adhesion this One Seven compressed air foam has a particularly homogeneous and fine foam structure. As a result One Seven compressed air foam forms a particularly stable and exceptionally dense blanket of extinguishing foam which enhances the above mentioned four extinguishing effects.
