If you don't have the wet chemical kind it's best to order or use a water mist extinguisher at hand. They can extinguisher class a class b rarely and class f also electrical. Just keep in note that wet chemical has a similar to the colour of foam extinguishers. If it's a big one you can tell its a wet chemical by the metal extension on the hose. Don't use water or you're in for an explosive and scorching hot surprise.
Can you use a wet chemical extinguisher to put out a (mostly plastic) microwave that’s on fire? Providing that the microwave is unplugged ofc. Surely, even if it was CAUSED by an electrical fire (class f), it’s just a class A fire once it’s unplugged? And therefore it’d make more sense to use the wet chemical rather than the CO2? Because CO2 isn’t suitable for class A?
Class F is NOT an electrical fire. Class F is for hot cooking oils and fats etc. electricity is not classified by a letter as it is its own risk and normally encompasses other materials. But to answer your question, a wet chemical is classed as Class A (solid fuels) AND class F. So yes, providing there was no live electricity, technically a wet chemical will tackle a plastic (class A) fire. But it's not recommended. Co2 will do the job for electrical and will be less messy. Failing that, a water extinguisher
These fire extinguishers been wet chemical are best for class F fires only, and the other types of extinguisher are not safe or even recommended for fires such as cooking fat or cooking oil.
