It is also good to remember that more dangerous than the flames is the smoke. Most people that die in fires are first overcome by smoke then are burnt after the fact. The smoke may be so thick that you could not even get to the flames to use a fire extinguisher. I agree with ThirdPig, call the FD first and then see if there is something that can be done without endangering yourself. Houses can be rebuilt, people can't.<br><br>Eric_c makes a good point about the corrosive effect of ABC extinguishers on electronics. The chemicals in ABC extinguishers are also highly corrosive on aluminum and should not be used on aircraft. They can do more long term damage to the aircraft structure than the fire might. Us pilots should have a BC type extinguisher in our hangar for fires that might be ignited during startup or refueling. Don't count on the fuel truck's extinguisher, many have been carrying ABC extinguishers lately. For in-flight fires you should carry a Halon extinguisher. Halon is very effective and doesn't leave a powdery residue that is impossible to clean up. It also does not create a dust cloud that is hazardous to breath and difficult to see through. However, Halon works by depriving the fire of oxygen so you need to ventilate the cabin so you will still be able to breath.
