I think that everyone should have a good extinguisher in both the home and vehicle. You might not be a race driver, but engine fires can start for almost no reason, and you might come upon a crash where you could help put out a fire and possibly save a life. <br><br>Using a dry chemical extinguisher is a messy deal, for your home you might want to think Halon. Just for info, in the home plain old baking soda can work well for the most common fire, the greas fire on the stove. <br><br>Check this url for more info on extinguishers than you ever wanted to know. Oh yes, I'll bet that your old extinguisher is shot. Check places like Costco for an affordable replacement...<br><br>http://www.hanford.gov/fire/safety/extingrs.htm
