Is there a UK equivalent to a BC Dry Chemical Extinguisher?
It seems that the new type "AF" is what is recommended. It is a watermist type extinguisher. While using water seems counterintuitive, it contains an additive that renders the water non conductive. When combined with the misting properties it smothers the fire. The other advantages are that it leaves no toxic residue and can be used in small areas without the concern of lung damage that can be a issue with dry powder.
