Powder fire extinguishers are suitable for use on class A, class B and class C fires but are used in different ways depending on the type of fire they are being used on.
Only tackle small fires with an extinguisher. If the fire has taken hold do not fight the fire but evacuate immediately and warn others of the fire, then call the fire and rescue service. Please be aware that the powder from the extinguisher spreads and might be inhaled. It can also reduce visibility. Do therefore only use with caution in enclosed spaces. If you tackle the fire make sure you stay at a safe distance and follow the instructions below.
