...snip...It is more important to have them close and handy to quickly attack the fire rather than running out to the garage for the big 20 lber and waste 30 seconds. I'd rather have a number of 2-5 lb extinguishers scattered throughout the house.
Close at hand is good - one (small - 2lb) attached to the wall in the Kitchen, one 10lb in the upstairs linen closet, one 10lb in the detached garage, one 5 lb in the basement, and another 10lb in the basement that gets moved to the den in the fall/winter when we MIGHT light the fireplace (have not in 2 years, but)
Why the 10 lbs jobs? I have a friend who gets full charged, good units that are near the end of their hydro test time for free. He's in the business - around here, for commercial use, they have to be swapped out or re-hydro tested - cheaper to swap. I get handed units with a year or so on their hydro, but are still pefectly good and inspected except for that
I also have 2 lb units in both the car and the truck
I'm trying to find a free Purple K unit for the shop, but....
