I was in New York City, recently, and came across two liquid nitrogen dewars on a street corner. One had a regulator on it and tubing running into a manhole in the street. I think the dewars had been there awhile as one had been tagged with graffiti. No one in sight that might have anything to do with the dewars.
Gas cylinders get "managed" in creative ways, it would seem. I guess chaining to a tree satisfies the "prevent from falling" requirement. Rolling along the pavement - ill-advised, certainly. I wonder what they were using the nitrogen for.

A company doing work on campus chained thee nitrogen compressed gas cylinders to a tree in front of a dormitory. And left them there, for several days. Two were capped, but one of them had a regulator attached, with tubing going into a hole in the ground.
One day, two of this company's employees were seen removing one of the cylinders from the tree (one with a cap). They lay in cylinder on its side on the ground, rolled it with their feet to the curb, then rolled it off the curb and into the street to their truck. There, they picked it up by hand and manually lifted it into their truck.
