Oxygen Storage

If storage under 300 cubic feet can be “open to the corridor” is there still a requirement to install a sign if the oxygen is stored in an enclosure versus being stored open to the corridor?  Would this be considered a Life Safety or an Environment of Care issue?

E-Sized Cylinders of Oxygen

We have a new building that is an annex to the hospital building where the 4th floor only is an overnight patient care floor and just now going through licensing.  We want to keep 12 e cylinders of oxygen on the floor.  Can you tell me what I have to do to be in compliance?

Oxygen Storage

Is there a code that says there must be 5 feet between an oxygen cylinder and an ignition source?
