We have multiple fire extinguishers. Kitchen Pantry, all bedroom closets and at least two in the garage. They are the next size up from the smaller ones.
We are now in a one level down sized home. But for 16 years a much larger home with 4 BRs on the 2nd floor (master on the main)
It was also a high house so also had one of those emergency roll out escape ladders in a central location in case my kids (at the time) or visitors could not get down the stairs. The fire extinguishers were a carry over from that house. Whenever visitors stayed I always made sure they knew the locations. It was also an "open" house with the main floor open to and through the second floor so my fear was always that the staircase could easily become unpassable.
Some I replaced to do age but it's easy to escape this new one level home.
I knew a whole young family who died in a house fire when I was a young adult. Both parents and two newborns. Horrible, one smoke detector in the hall. I never found out from the fire department if it was working, I knew at the time that possible there was no battery in it..
It only takes a few minutes and a few dollars and some thought to protect your family if the unimaginable happens.
PS DO NOT FORGET TO PUT IN A CO (carbon monoxide) detector. CO will kill you and you wont even know it's happening.
(I have a personal story for that one too, I was very young, married and kids and I had the detector)
In addition to the deaths, over 100,000 Americans go to the hospital each year. Click the link for facts.
