What I don’t understand is how people believe a volatile gas gets absorbed into metal
And if it can , then why doesn’t it just escape through it.

must be thinking of radiation

I don't think anyone here is suggesting propane can "soak into" the metal cylinder but clearly something is preventing a simple flush with water from removing all of the propane.
Propane is not miscible which may be a clue I guess because you are relying on the water to mechanically remove any propane gas, liquid or even slushy propane ice (I can believe that). You are also relying on a water flush to remove any oily residue (from the stenching agent?) or any other contaminant which might have found its way into the tank. I wouldn't bet my life on it....
I think it is perfectly possible for some sticky, oily residue to allow some kind of fuel cocktail to develop as a gas within the enclosed tank even after it has been drained. That's my best guess because it appears that tanks can explode after being flushed so there has to be some mechanism for a fuel gas to develop inside an "empty" tank.
Caveat weldor.
It’s not the propane that sticks to metal. It’s the odourising agent. Mercaptans are some of the most smelliest stickiest compounds know
I’m working on a case where a life was lost involving a drum being cut open
I have read and researched many many things
There is a safe way to do it. It happens every day in the world at high risk sites. People don’t die
And I know that propane doesn’t stick to metal
I was waiting for that. It’s called hydrogen embrittlement. It’s now quite well known about
Propane isn’t the same
I know, it was just a bit of trivia.
If advising folk on a public forum (don’t assume folk have common sense) regarding cutting or drilling into a gas tank it’s best to be cautious, reading some replies they are a bit blasé this time round. When doing anything like this better to be safe than sorry. And what applies to a propane tank certainly does NOT apply to a petrol tank!
I should have been more explicit: if an oily residue can remain inside a tank that has been flushed with water, perhaps that residue may be contaminated with propane or some byproduct which can dissolve into an oil.
Like I said there has to be something because we all know that these things have a habit of gong off with a bang once in a while. I used to hate chemistry at school so I am by no means suggesting I know what's going on. I just know that something is...
<edit> I just knew you'd have written a report on on it!
Regarding the common sense as mentioned earlier. One thing I have learnt over the years is that what many of us consider to be common sense isnt so common in some individuals.
Try and make anything idiot proof and a better idiot will be along in no time just prove you are wrong.
