O2 Wrench

[Nerd13]

I honestly don't know. The places I've seen it used were pretty low abuse, however I do wonder how much abuse oxygen tanks really need to take if people take care of them. I realize, however, that often is not the case in many systems.

It's not that our tanks take abuse so much as the chains do. Our tanks hang on the side of our cot near the head so moving the head portion up or down frequently catches the chain and they break with very little resistance. We try to leave the wrenches right on top of the tank but sometimes it just doesn't work out.
