Walt, Stay away from Halon! As you know Halon works by depleting the area of Oxygen to extinguish the fire. When the area you are in is robbed of it's O2, you have less than 15 seconds before blacking out. In the event of a leak in the Halon system, you would have no warning before you "fall asleep" while driving without time to bring the car to a safe stop and bail out. Halon is odorless and can enter the passenger compartment without warning. There are O2 monitor alarms available, however they are expensive and still may not give you enough warning to stop the car and get out. Also, keep in mind the small size of the Delorean's window openings. A better bet may be a smoke/fire sensor to alert you of a possible situation early enough to stop the car and use a manual hand held extinguisher. An easily accessible battery cut off switch is a really useful thing if fire is a concern. IN THE EVENT YOUR DELOREAN IS ON FIRE, FOLLOW THESE STEPS (IN ORDER): 1. Stop car, get out! 2. Call 911! 3. Take photos of the inferno to post on the DML. (important) 4. Call insurance company and make a claim. 5. Check Ebay for a new DeLorean. 6. Post your sob story on DML for all of us to console you. Dumb joke of the week: Seating hostess at the DeLorean cafe greeting customer: "Welcome, would you like smoking, or charred beyond recognition sir?" -Daniel Deutsch (Orlando)
