Foam Spray or Aqueous Film Forming Foam Extinguishers (known as AFFF) have a cream panel. They remove the OXYGEN from a fire by smothering it; and they can be used on Class A or Class B fires.
To use the extinguisher, you need to pull off the safety tag to break the seal.
Then pull out the pin and test that it works by pointing it AWAY from the fire. Make sure you squeeze the handle until the extinguishing agent comes out.
It’s important you know that Foam Spray Extinguishers are used in slightly different ways depending on the class of fire you’re tackling.
If you’re using this extinguisher on a Class A fire, you need to aim the jet at the base of the fire, squeeze the handle, and keep moving the jet of foam across the fire.
However, if you’re using this extinguisher on a Class B fire, make sure you DON’T aim the jet directly at the liquid. You need to aim the jet at an edge if it’s in a container, OR at a nearby surface, so the foam can flow across and extinguish the fire.
The nozzle on the extinguisher can either be a jet OR a spray and it’ll last between 35 seconds to a minute. Foam Spray Extinguishers have a range of 4 to 5 metres.
Never use foam spray extinguishers on Class C or Class F fires, OR on live electrical equipment.
