I’ve never had to directly deal with a fire, but after an incident where a roommate took the only extinguisher in the house when he moved out and an electrical short from an old crappy dimmer switch, I’m big on having a couple on-hand.
I also have way too many hobbies involving stuff that can easily catch fire and they’re so cheap that I have multiple on each floor. 2 on the upper floor where my sim-rig, 3D printers, reloading supplies, and electronics soldering bench are. One in the kitchen and one in the master bedroom. 2 in the garage (excluding the one that’s mounted in my old MG), and finally one in the basement since there’s basically nothing down there.
I take the “Two is one, and one is none” mindset on it. I don’t think most people need to have 2 on every floor like I do, but I still would be very concerned about having any sort of shop and it not having its own dedicated extinguisher. I’ve got the little 2.5lb guys in the house, but I want a 10lb’er anywhere with fuel sources. They’re so cheap and take up so little space, I really don’t get why you wouldn’t want more than one.
I’ve never really had anything more than some brake cleaner residue catch fire or a flare up in the kitchen, but it’s just such a cheap form of insurance that I’d rather have “too many” than too few.
