Let me take a minute and explain how a properly used and maintained propane system works very simply. There is a shut off at the tank it should be shut off IE NO FUEL IN LINE OR BOAT. RTFM(It was more her boat than his, actually. Anyway.)
No, it did not explode.
And your point is? I don't even know what stove they had on the boat (they have since moved). Let us assume it was indeed gas.
Then you have clearly shown that there is ONE boat with an LPG system that did NOT immediately blow up. Even though it was certainly possible, just as the boat that exploded this week because of the rat bite.
I would feel so much better know if I had a gas system.
What if a rat eats through your storage bottle and you accidentally point your lit blow torch it the hole where alcohol is leaking out.And if the valve seal(s) fail, or you get distracted and simply forget, or if the flame gets blown out, etc.???
Let ME take a minute and explain to you how alcohol stoves work --- they CANNOT produce explosive gases (I.E., NO POTENTIALLY EXPLOSIVE FUMES IN THE BILGE, OR ON THE BOAT IN GENERAL; NONE, ZERO, NADDA, ZIP, ZILCH). Propane, on the other hand IS an explosion risk, RTFM*.
(* - From the manual for a Dickinson propane unit: "LPG is heavier than air and if allowed will settle in lower areas resulting in a potential explosion.")
The problem with coming into the middle of a thread like this is you miss all the previous posts like where I gave a very specific positive example of years of use with a a non pressurized alcohol stove, they are great. Propane stoves are also great and safe as is kerosene when used properly.As I said earlier, no fuel is absolutely safe. Propane is inherently more risky than alcohol. No amount of valves, sniffers, and assorted safety gizmos will ever change that simple fact. If you feel propane is worth the risk, fine, feel free. It's your life. But I will also feel free to tell folks the facts. If I'm wrong, I take a minute or two longer to cook my lunch. If you're wrong, BOOM! You make your choice, I'll make mine.
End of discussion, as far as I'm concerned.
