Take a look at the Element fire extinguishers. They operate like a road flare and are good for Class A, B, C, and K fires. I have the traditional fire extinguishers on my Dawg Haus (boat) and in the Dog Kennel (Prevost) but I have also added at least one Element Fire extinguisher in each. They are non-corrosive and do not leave a film to clean up. The best part is that when started, they last much longer than a traditional fire extinguisher. They claim the E50 run time is 50 seconds which is equivalent to 5 – 5 pound bottles. To me, this run time is very important. I came across a vehicle several years ago that had a small engine fire that was getting bigger quickly. It took all of 2 extinguishers to put out that fire.
