    A bucket of gas-soaked paper and a store gas pump are TOTALLY different items, so I stand by my post.
    Can we stop now?

    Sure, but I'd love it if you'd edit your post to remove the blanket claim that "gasoline fumes are not ignitable". The whole reason we have gasoline is that it is ignitable -- wouldn't do much good if it didn't burn in engines -- and part of the price we pay for that utility is a lot of (sometimes stupid, sometimes innocent) burn victims.

    Oh, and if you're smoking at a gas pump close to me, I'll still get worked up about it. But we don't have to work that out here.

    I wonder, does this mean I should stop lighting my shots of 100 proof rum before I drink them?....Kidding :D

    Just remember to take the cigarette out of your mouth first! The rum might accidentally light it. ;)

    I don't care, it's NOT acceptable to smoke while pumping gas. No way I'm letting some idiot put me at risk. It's my life he's gambling with! If he wants to play Russian Roulette when I'm not around that's fine but it's a different story when I'm right next to him. Anything that puts me at risk due to someone else's stupidity demands an immediate response!

    I agree gas fumes are flammable. But for them to ignite, you need the perfect amount of oxygen to do so. In an engine the ratio is 14.7 parts air to 1 part gasoline. Fuel injectors spray a mist or vapor into intake air, and then compressed into the cylinder by a piston, spark plug ignites the fuel air mixture and an explosion, or combustion occurs forcing the piston to the bottom of the cylinder, turning the crankshaft partially around (each piston in a V8 engine will turn the crankshaft 45°). Point is, is that it takes the perfect scenario to ignite fuel. Too much air or too much fuel and it wont happen.

    I have seen people put cigarettes out in gasaline and nothing happens. But you are right, still shouldnt smoke at a fuel pump.

    Gasoline's explosive range in air is 1.4% to 7.1%. Above a pool of gasoline, in the open air, the layer of vapor with that concentration will be pretty thin. Over clothes soaked with an accidental gas spill, the layer will be unpredictably thicker. And it's just bad luck if the gas spill surprises you enough to open your mouth, dropping the lit cigarette down the front of your clothes...

    Speaking of stupid behavior, I was once working in the yard and poured a little gasoline to help start a fire on the brush pile. Decided to test the Hollywood thing, so poured a little trail leading away from the pile so I wouldn't blow myself up, then dropped my ciggie into a puddle at the close end of the "fuse" trail.

    It fell into the small puddle of gas and went out with a small hiss, just as if I had dropped it into a puddle of water!

    So @Brina 's claim is not entirely unsupported. I have tested it personally.

    That being said, would I play with this and always assume that you could drop a lit cigarette into a puddle of gas and have it sizzle out? Of course not. That's why they put those warnings on gas pumps about static electricity discharges. Just one little spark and the vapor, and *poof!*. (Car engines use spark plugs, after all.)

    So I think both of you are in some ways correct. @Brina in saying that a cigarette will not always ignite gasoline (though perhaps wrong to make a blanket assertion that that's always the case), and @-jeffB for saying that it would be foolhardy to always take this for granted, as there are probably many circumstances in which that could happen, so ... better safe than sorry.

    There's a world of difference between "it sometimes won't happen" and "it will never happen". That's what I'm pounding on.

    I've accidentally run a red light once or twice without getting hit. I still don't go around telling people "getting hit because you run a red light is a Hollywood myth".

    OK, LITTLE MAN. You can have the last word.
    Can we let this thread die now?

    You really need to research this further. Sorry but it's not a Hollywood legend. There are many things that can ignite gas fumes.

    Well, I can't say that I'll never post in it again, but I will say that I won't always post in it again. ;)

    Some humor to lighten up the post. Anything wrong with that ? If you have an alert that immediately goes off once anyone posts anywhere on this site then who's bored ? :facepalm:

    Don't you see an alert when there's new activity on a thread where you've posted?

    Top right corner, my comment, 'no comment' was to break the hostile responses I was seeing. Reason, each of us will have an opinion on someone's post that is fine, but I saw some of the posts as berating and an attempt to humiliate the other's post. "Coin Talk" is a site to educate. I'm sure GDJMSP will agree with that. We are all quite knowledgeable on many specific things some more than others and many of you on this site are a lot smarter and have an incredible and extensive numismatic history that help us "still learning". You don't have to "one up" the other because you feel it's needed. Explain and move on. If I offended anyone with my short post I'm sorry, but as the old saying goes, "Lighten up Francis". and jeffB that last comment was a blanket statement not directed at you.

    How do you keep up with all those alerts? I want to get one of those? I sit here for what seems like twenty minutes with nothing happening then "bang" - new alert but it is just a joke or a member posting something that's been answered the day before! :arghh::arghh::arghh:

    No I don't. I only get one when someone quotes what I posted, not when someone else just posts to the thread.
