They have that in FL too, Jacksonville anyway. Very moist area.

LOL.It would take a big hole to make those tanks move. Most of them are chained down anyway.

I've seen a dive tank take off. It was pretty exciting for a a few seconds.

And there is a difference between gas and liquified gas.

As for flammable liquids. They can be pretty wild to deal with.

As my link shows, they're in New York and Los Angeles too. They're probably in all cities with underground lines.

It wouldn't take much of a hole. The boiling pressure of liquid nitrogen is extremely high at room temperature and even higher at our summer temperatures. (Technically, it's a critical fluid, not a liquid inside the tanks.) That little hole would quickly be ripped apart. I wouldn't want to be around when it happened. Luckily those tanks are pretty solid, but they're not impenetrable.

kenshi - don't be sticking your tongue (or any other body parts) on these frosty tanks to cool off in the summer.

Heh. They only develop frost when gas is coming out and mainly in the winter. I used to deal with similar tanks with liquid oxygen. When I started the day, there would be no frost at all but when I finished in winter, the top would be covered by a mound of "snow", my glove would stick to the valve, and I'd have to break the ice before I could turn it.

I still have a picture where I cut the top off a plastic bottle, put some liquid oxygen in it, and then put in a dial thermometer. The needle went past the lowest temperature and way into the hot temperatures. It also permanently screwed up the thermometer so it reads a very wrong temperature. I wouldn't stick my finger in it for sure.
