I don't know that there are any regulations here in Milwaukee, Wisconsin USA
but we recently added a room oxygen monitor to our liquid nitrogen storage
tank room. It's made by Gastech and is called the SafeTNet Oxygen monitor.
It was very easy to put up and is very easy to calibrate. The only down side
is that you want to put it at a level where the alarm won't go off when a
tank cover is removed, but not too high that it's not giving accurate
readouts when a person is actually in the room working.

Most of the time our techs are in the room for such a short period of time
that the personal monitors don't seem like they would be worth it.

Anyway, if anyone is looking to purchase an oxygen monitor for a room, feel
free to contact me about the one we own.
