There are just two types of dry powder fire extinguishers available: standard and specialist. Standard dry powder extinguishers can extinguish almost any type of fire. Specialist dry powder extinguishers are for certain types of metal fires. However, because of the dispersal of powder, it’s important not to use them in enclosed spaces.
Dry powder extinguishers can also be known as ABC fire extinguishers, multi-purpose extinguishers or dry chemical extinguishers.
Dry powder fire extinguishers have a blue-coloured label stating ‘DRY POWDER’. It should also have a sign above or next to the extinguisher that states ‘Powder Extinguisher’.
Dry powder extinguishers come in foam sizes:
These extinguishers work by smothering a fire and creating a barrier between the source of the fire and oxygen. However, because there’s no cooling effect with a dry powder extinguisher, there’s a small chance of the fire re-igniting.
They’re suited to open or outdoor environments where there’s a fire risk from several different sources. An example would be a garage forecourt or a workshop, where there’s a fire risk present from fuel, vehicles, and chemicals.
