I see nothing in NFPA 99, 2012 edition to limit a project from performing the following.
Please review and let me know if I have missed something here. I look forward to your opinions.
A facility has issued plans and specifications to install new outlets in a room that is located in an older building of the hospital. The zone valve that exists is across a main hall in the newer building that the hospital wants the contractor to install these new outlets (with vibration isolators installed between the outlets and zone valve at the buildings interface) located in the older building. The new outlets are located in the same story as the existing zone valve. The existing patient care area served is not a critical care area and the new room with the outlets is a CT Scan Room. (Possible ventilator patients since this is a Trauma Center). There is an area alarm panel in the existing patient care area served by the existing zone valve location.
Currently the AHJ recognizes 2012 edition of NFPA 99 and I find nothing within 5.1.4.8 addressing this specific scenario.
I see the code IMPLIES there is a need for the building main valve in 5.1.4.5 when the medical gas pipes enter the building. I do not know if this is of any significance.
The project requires the vibration isolators at the building interface.
