Excellent question. It will be my first season heating with a wood stove as well and I am getting ready to purchase some fire extinguishers. To add to your original question, how many fire extinguishers should one buy? I was thinking 2 for the living room where the stove is and possibly one for each of the occupied bedrooms. Or does it not make sense to purchase one for the bedrooms?
I don't know as there is any one "right" answer to this. However, consider the following in making your own decision.
A residential fire extinguisher is really only good for putting out rather small fires. Fires tend to grow rather fast once established so if you are going to stay and try to fight a fire (especially with a small residential extinguisher) you had best have it handy - no time to go running half way across the house.
Excellent point . . . and very true.
Second point - place the extinguisher(s) where they are most likely to be needed. This would be where fires are likely to start and someone will be when the fire is noticed. For most people this would be the kitchen as for whatever reason, this seems to be where the greatest danger of home fires exist. I don't know what #2 is generically, but look around your own home and your behaviors and you should be able to figure it out somewhat.
I imagine that if you aren't a smoker, and you don't burn candles etc, then you may not have any ignition sources in your bedroom - then again, maybe you do.
Ding. Ding. We have a winner . . . kitchens are #1. Bedrooms are #2. However, the idea of putting "one for each of the occupied bedrooms" may not be the most prudent as that may not in fact be where fires are most likely to start for you.
For us, I put one in the kitchen, in the hall at the top of the stairs/loft area in the 2nd floor (main throughfare/central location) and another at base of stairs at basement. Then when we added the woodstove I bought a large one to put near the stove (it landed between the kitchen and woodstove) so in case something near the stove caught - and the bonus being that it improved coverage for the kitchen too.
Now my question for the experts who may be reading this - I've heard that the dry chemical extinguishers can "pack down" inside and become useless over time even if the pressure gauge reads in the green. If this is true then how long does this take? Is there any way to know before a real emergency? The obvious followup to this is should I simply replace these after x years?
I wouldn't say useless . . . but what can happen over time is the same thing that can happen with baking soda, sugar, etc. when left in one place without movement . . .it can pack down into chunks. The result can be that the nitrogen gas used to expel the powder will not be able to blow out all or as much of the extinguishment agent. You can easily prevent this from happening by turning your extinguisher over once a month or every other month and just giving the extinguisher a whack on the side . . . this should cause the powder to fall and loosen up. I'm not sure how long the packing takes . . . just turn the extinguisher over once in a while and give it a whack. There's really no way to tell until you use the extinguisher since the gauge just reads the pressure from the nitrogen gas. Most home fire extinguishers can be good for 10-15 years before they need replacing.
