Foam extinguishers are regarded as multipurpose and can be used on both Class A and Class B fires. They are increasingly used where water extinguishers would normally be provided such as an office environment as well as where flammable liquids are present. They can also be used on electrical fires. This information can be found on the label. AFFF or Aqueous Film-Forming Foam Extinguishers work by excluding the oxygen from the fire and thereby smothering it. As its name suggests it’s applied as a watery film rather than a thick blanket of traditional foam.
The method of application of foam extinguishers varies according to the class of fire it’s being used on. For Class B fires that involve flammable liquids, the jet of the extinguisher should not be aimed directly at the liquid. But instead directed at an edge if it’s in a container or at a nearby surface allowing to flow across.
To use foam extinguishers on Class A fires the procedure and the way you use it is the same as for a water type extinguisher.
Some nozzles are jet and some are spray and will last between 35 seconds to 1 minute and they have a range of 4 to 5 meters.
