Page | 54- Medical Gas Outlets
a. Coordinate the type of medical gas outlet required at each location. (DISS outlets are installed in a major ity
of areas. Quick connect outlets are required in some rooms whe re spe ed is a consideration but heavy usage
is not expected.)
b. Coordinate the pa rtic ular generation of the required medi cal gas outlets during the Design Phase.
c. Specification sha ll prov ide for an extra five percent, no less tha n one no greater than 10 pe rcent, of each
type of medical gas outlet to be furnishe d within each project to allow change ou ts of the medical gas outlet
type where the Owner may request so at the completion of cons truction. All remaining unused medical gas
outlets shall be turned over t o the Owner. - Medical Gas Valves
a. Medical gas zone valves shall be installed at locations pe r NFPA guidelines. Whe re there a re questions at
non-standard locations, review t he s pecifics with Respiratory Therapy.
b. Lockable valve boxes shall be supplied where so requ ested by t he Owner. - Medical Gas Piping
Note: Abandoned gas piping must be removed back to a shut off valve.
a. Medical gas piping may be either Type K or Type L, ASTM B819. The minimum size of medical gas
piping ins talled abov e-ceiling shall be ½” diameter. The maximum length of r un for ½” diameter
medi cal gas pipi ng shall be 30 feet. The Design Professional shall give consideration to possibl e future
additions to the medical gas distribution system for a specific project. (Installation of piping sizes larger
than ½” diameter is often a cost-effective means to accommoda te f uture expans ion or r evisions .)
b. Isolation v alves for each horizontal ta ke-offs f rom medical gas r isers shall be i nstalled and in accessible
locations.
c. Label all medical gas piping every 20 feet and at least on e in every room and on either si de of the walls
to rooms. Label medi cal gas pi pes accor di ng to the f ollowing schedul e:
i. Oxygen: white lettering with green background.
ii. Medical vacuum: black lettering with white background.
iii. Nitrous oxide: white lettering with blue background.
iv. Medical air: black lettering with yellow background.
v. Nitrogen: white lettering with black background.
vi. W.A.G.D.: white lettering with black background.
vii. Laboratory air: black lettering with yellow background. - Area Alarm Panels
a. Coordinate the location of all area alarm panels with the Users. Locate area alarm panels adjacent to medical
zone valve boxes.
b. The specifications shall require that the Contractor set and adjust all timing and sequencing of alarms per the
directions of Capital Management and Maintenance Engineering during the Construction Phase. This is work
that is done via internal settings at each area alarm panel. - Zone Valve Box
a. Amico VBU-P with secondary sensor part
22 61 00 Compressed- Air S ystems f or L aboratory and Healthcare Facilities - Medical Air Compressors
a. Install duplex medical air compressors for each new addition or where medical air capacity expansion is
required.
b. All compressors shall meet current NFPA guidelines for medical air compressors.
c. Medical air compressors shall be manufactured by Kolbelco, Ingersoll-Rand or Quincy.
