Ok, so I have the requisite dry chemical extinguishers in my garage and in my house. The main problem I see with these is they make a terrible mess when you use them. And they can be very damaging to the vehicle, in the event of a car fire. We had a post over on FSJ Network about Halon and Halotron fire extinguishers. Halon is banned now, and Halotron is somewhat less effective. They leave no residue. The main problem with these is they are wildly expensive. I asked about 1) CO2 extinguishers and 2) foam extinguishers. The welding guys like CO2 for nuisance fires - no residue, cheap to refill, multiple uses prior to refilling. But it seems their initial cost is rather high, esp. when you can't depend on it for anything more than a small-scale fire. The foam extinguishers seem ideal for the garage - http://www.firedot.com/mall/AR_AFFF.htm - they are good for both class A (wood and paper) and class B (flammable liquids). So you could use them on either the building or a car fire. And they seem reasonably priced (ie $100-200 for a large one). Anyone here know anything about these?
