Another exploding boat.



Gasoline? Propane? Anybody know what caused this explosion, apart from operator stupidity? I am surprised nobody died.

Re: Another exploding boat.

I don’t know how you get operator stupidity out of the video. The boat was probably overloaded but that doesn’t explain the explosion.

Re: Another exploding boat.

Good demonstration of how fiberglass burns.

I didn't "Get" anything. Speculating and asking. Most mishaps with gasoline vapors or propane can be avoided with proper safety procedures. Failing to follow proper safety procedures definitely constitutes operator stupidity.

I don't like gasoline. I don't like propane. They are inherently unsafe. But I have to admit the risk is minimal with proper installation, inspection, and operation, and that true accidents with either, where there is no lack of proper safety procedure, are uncommon. And so yes, I am speculating that there may have been operator error. AKA stupidity.

Yes, I know fiberglass can burn furiously and certainly after the first few seconds, this was largely a fiberglass fire. However, fiberglass does not explode. That is why I am pointing the finger at things that DO explode when mishandled.

So back to my QUESTION, the point of the post. Does anybody KNOW what happened?

Re: Another exploding boat.

As a starting point for speculation, data from an insurance company:

Nice. But this includes all fires, not just fires started by an explosion. How about some data that is relevant to this instance? Causes of explosions? Even more to the point, what is the breakdown of different fuel sources that resulted in explosions?

What I really am interested in, is what caused this particular explosion, not statistics. I am sure that statistics would be about evenly split between gasoline and propane, when it comes to the actual fuel causing an explosion. The spark or heat source aside. Really, what else is there? Pyrotechnics, firearms/ammo, butane and butane lighters, what else? Diesel could of course be heated to vaporization and be explosive with the right mixture of fuel and air, but this isn't going to occur very often. Maybe a malfunctioning diesel stove? In rare instances hydrogen could concievably be trapped and concentrated, from charging batteries, and explode, but hydrogen tends to rise and float away, instead of sinking into bilges and staying there until moved by ventilating.

Anyway, we are speculating. I am wondering what the actual cause of the explosion was.
