Casady If yer worried about a 16 oz canister, are you more worried about the logs floating around out there from the rivers? So, it's ok to toss small stuff like floating metal? Just because there's one hazard already there, doesn't mean another deliberately placed is ok. "neutral Buoyancy" simply means the same average density as water. Putting the object under water will still allow it to release gas which will rise to the surface. In spite of the propane being higher density than air, some will diffuse to higher than the transom and then will sink into the bilge, all basic physics. The hazard to my boat from this canister was orders of magnitude greater than the hazard to any other boat from an empty canister. 16 oz?? Come on. It would take a heck of a lot more, and you said yourself it was already leaking. I think you just didn't think things through and panicked. |

Stop digging. *It's laughable to say a small cannister of slowly leaking propane bobbing in the sea will blow up your boat. A mere foot away from the canister the gas will be too dilute to combust. A fart is orders of magnitude more likely to ignite than any measure of gas that gets to your bilge. You have no certitude here. Just nav hazard creation. You do not have much experience with this sort of thing it seems. Do NOT try it. Combustibility is not a simple matter of concentration because 100% propane will not ignite whereas if you dilute it, the probability of ignition goes waaaaay up. At higher values it goes down again. Being heavier than air is the major danger to boats because it settles to the lowest point where it can reach a higher density than it would be at deck height. The same is true to a lesser degree of gasoline vapors. Ever seen someone throw a lit cigarette into a bucket of gas, nothing happens (nearly 100% concentration) whereas if he held the cig above the container...............This is why boats have bilge blowers. You're nuts. There's no way that small amount of propane was a hazard if it was in the water, down current and bubbling. Maybe 5 minutes then it would be empty. |

Hazard to navigation? *WHAT? *In a few hours, it will be empty and you think a small propane canister is a hazard to nav? *Be serious. Too bad you can't say all this with certitude. Here is a thought experiment for you. DO NOT ACTUALLY DO THIS ( I figured I had to add that warning) Take a Coleman 16 oz cylinder and push a nail into the threaded part so that it leaks constantly (ie, the built in valve is jammed open). Drop it into a children's wadding pool. Wait about an hour (no wind) and go stand next to said pool and strike your lighter. What will happen? If one poster here is correct, nothing will happen because: 1. The leaking cylinder is underwater 2. The high density propane cannot reach up to where you strike the lighter. In reality what will happen is you will either end up in the hospital or morgue because being under a few inches of water will not stop the cylinder from leaking and the propane will produce a cloud centered above the cylinder. This clouds density will vary radially from the spot above the tank in the water. At your height, the density will get to the point where the Oxygen mix is right leading to easier ignition than if you were next to the water. A cloud of propane on the water is a bomb waiting to be set off even by someone 10' above and was a major danger to my boat. It is absolutely certain that the propane was more danger to me than the empty cylinder would be to anyone else. Even better, the salt water will corrode the thin walled cylinder thru in a month and sink it. That's in no way equivalent to letting it leak down current from you in a vast ocean. You just blew it and are now trying to justify freaking out. |

A 16 oz propane container has enough explosive potential to sink a large boat. You can make quite an explosion by putting a few seconds worth of the propane in a bag and igniting it. YES, I truly do mean the coleman stove size canisters. I also know from experience that a few mg of calcium carbide in water will produce a mega explosion if the acetylene is allowed to accumulate. Propane is almost as dangerous. Clearly none of you has any experience with fuel air explosions. The amount of ignorance exhibited here is astonishing and dangerous. All you have to do is google propane boat accidents to see. |

Fortunately I've never seen a propane explosion but they can be spectacular and deadly, that's well established. Better to be safe than sorry in any case, and leaking cannisters are no joke. Here's a thought: Since half used cannisters are prone to leakage after removal, why not carry a spare torch tip or two that you could screw onto a leaking cylinder. They are inexpensive and should be enough to seal it. |
