I was kind of hoping someone with engineering experience would tell me that with recent safety improvements and double-super-inverse-pressure-locks or something it's perfectly safe to smoke a cigarette in one hand with a dripping gas nozzle in the other while standing over a literal lake of gasoline but nobody has so I'm thinking maybe it's not the best idea after all.
@evan This matches my impression. I mean, I don't smoke so wouldn't be putting myself in such a situation, my impression is it is not not as dangerous as you might think.
@virtuous_sloth AFAICT the big danger is the vapour, and they've done a lot to prevent that leaking all over the place, so it's a lot safer than it used to be when I was a kid and you could smell a gas station from a block away.
@evan When I was in high school, I worked as a grease monkey for a couple of summers in a gas station owned by family friends. When it was busy, one of the owners, who was an expert mechanic, would leave the garage and help pump gas. He almost always had a lit cigarette dangling from his mouth. Sometimes he'd have it in his hand while pumping gas, so he could speak more clearly with a customer. The looks he'd get. Never an incident with fire. Sadly he died of lung cancer. He was a nice guy.
@evan But thats my point, even the vapour is not that dangerous.
When gasoline is spilled on the ground and catches fire, there is a thin layer above it where it burns well, and beyond that, even though you can smell it, it does not burn.
