Well, that was easy.
Replacements for our two 20-year-old extinguishers
promised within 15-20 days.
Do you suppose they just happened to have ~40 million extinguishers stockpiled in the warehouse?
These two played a large role in a incident in our garage only three months after they were purchased. Late one night, stepson and his buddy were doing maintenance on the buddy's car - oil change, plugs, fuel filter, etc. Thinking they were finished, they started the car. They realized after a bit that fuel was pumping onto the engine and spreading across the floor, at which time it ignited before they could switch off the engine. Apparently somebody failed to reconnect/tighten one of the fuel lines. The resulting "WHUUMP" and shouts of "Fire" woke me upstairs. Ran down the stairs (starkers), found both boys flittering about waving bits of cardboard box.
I grabbed one extinguisher from the end of the workbench, told buddy to shut off engine to stop gas flow and sent stepson after the other extinguisher from the kitchen. We used all of one extinguisher and part of the second to get everything out, probably within a couple minutes. My wife had called 911, but it took about ten minutes for them to arrive (time enough be sure all the fire was out, get dressed, roll the car out into the drive and still wait), so I'd expect that would have been long enough for the car to be toast and for the fire to have spread to the garage and contents. As it was, we had no actual damage(but quite a powder mess), and after fixing the fuel line, the buddy drove his car home.
If you don't have extinguishers in your car/home, I can only hope you never have cause to regret their absence.
