I don't mean what I write to be an attack on you. I do think this is something relevant to discuss.
We have not had a fire on our boat, but I HAVE investigated various industrial fires, including at one point trying to see how well fiberglass gel coat would burn - conducting experiments on my sidewalk with a propane torch with material retrieved from residue in a spray booth that was making truck caps - the process is similar to making fiberglass boats. [IIRC, I could ignite the fiberglass, but it wouldn't keep alight unless I kept some heat on it. If I removed the torch, it went out. Note - if you have a fire on a fiberglass boat, I would think it wouldn't go out because the fire would keep heat on the fiberglass.] I've also done an accident investigation on an aluminum fines fire BTW. Aluminum dust when it oxidizes (which it will do if it gets wet) is another thing that can have an exothermic reaction like the one you reported with the container of charcoal and that oxidation also produces hydrogen gas. The people who experienced the explosion compared it to the space shuttle liftoff. Incidentally there is a specific type fire extinguisher for putting this type of fire out. >The only thing I could add is that I don't have a CO2 extinguisher aboard.
