No Smoking Propane 

Well, two more days till I'm out of here... so it's time to share another story. About a week ago some of us were coming back from lunch. We had just parked in the lot, where there happens to be a giant propane tank, at least as large as a railroad car (no exaggeration there - it's huge). It's surrounded by a chain link fence with signs all over it that say:

Danger
No Smoking
Propane

As we were walking back towards the building, two other engineers in our group (who shall remain nameless) were walking towards the building at the same time, having just finished smoking some cigarettes next to the enormous propane tank. The following conversation ensued (taken from my best memory of course):

Coworker: "Decided not to pay attention to the signs?"
Smoker: "The sign says 'No smoking propane'. We weren't smoking propane, we were smoking cigarettes."

Since you put it that way, I'm sure it wasn't dangerous then. One of the other guys in my group mentioned that when those tanks go, they usually fail on one end or the other... resulting in something like a rocket launch going at least 1/2 mile. The way the tank is oriented then, it would either take out a school in one direction, or some homes on the other side of a field in the other. But he said, it probably won't fail. At least our building would be safe... but somehow I don't want to put my trust in probably.
