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.
