In reply to Lankyman:
I guess the question is what are you planning on burning? Do you have a history with kitchen fires?
Or is your property especially a concern?
In a kitchen (pan etc) if a wet t towel or fire blanket won't put it out, you're already in too deep tbh. Having used these many times, it's a skill, as are fire extinguishers. I'd suggest some practice if possible.
Whatever you have needs to be easy to get to. Packed in a busy cupboard is no use. Might as well not have one.
Powder although good is very messy and reduces visibility when used. And chokes you. But it does put fire out.
Co2 is next to useless on pan fires as they can and do quickly reignite.
Foam is ok. But on hot fat fires again is dubious to effectiveness as the heat burns off/evaporates the foam. Wet chemical is for hot fat fires. Normally only fitted in commercial and high risk situations.
Water is useful for getting out the building but not for fat style fires as it makes the flames far bigger and scarier.
In short. A fire blanket. And examine why you feel you need a fire extinguisher and risk reduce. Then consider an extinguisher.
Good luck to your toast! Kev.
