Hi, I am a firefighter and generally extinguishers are fitted with burst disks and are burst pressure rated to about 50 times normal pressure. Have never heard of one bursting in a car in 20 years. The reason you exchange white powder extinguishers that are in vehicles every three years is that the constant bumping around compacts the powder and it won't work.

Ones on a wall at home should be changed out every six years. And to keep on the theme of preparedness I hope everyone has at least a couple of photo electric smoke detectors in their homes and that they change the batteries every 12 months??? Photo electric ones are better than the old ionization ones BTW.

A lot of people don't realize that when they are asleep their noses switch off and they WILL NOT smell the smoke and wake up. No detectors and you will never wake up.
