H.
Locations of piped medical gas station outlets and vacuum
station inlets are indicated in VA Program Guide 7610,
Equipment Guide List, under "Outlets".
I.
Provide protective pipe enclosure for exterior oxygen line.
Burial depth shall be a minimum 600 mm (two feet) below grade.
J.
Coordinate the requirement for the use of adult ventilators in
the Operating Rooms, Cardiac Care, ICU, and Recovery Area with
the VAMC. Design the oxygen and medical air systems to
accommodate the ventilators.
K.
Oxygen System: Minimum design flow rate for any pipe section
is 200 L/min (7 scfm).
L.
Vacuum System: Minimum design flow rate for any pipe section
is 100 L/min (3 scfm).
M.
Medical Air System: Minimum design flow rate for any pipe
section is 200 L/min (7 scfm).

Alarms:
A.
To insure continuous responsible observation, two master
system alarms, in separate warning locations, are required for
each medical gas and vacuum system.
1.
The primary warning location shall be supervised by
engineering personnel, and is required to be located at
one of the following (in order of priority): boiler plant
control office, engineering control center, or in the
office or principal working area of the individual
responsible for the maintenance of the medical gas system.
2.
The secondary warning location shall be located to assure
continuous surveillance during the working hours of the
facility. Suitable secondary warning locations may include
intensive care nursing unit, fire station, telephone
switchboard, security office or other continuously staffed
location.
3.
Coordinate both master alarm panel locations with the user
facility and the other design services. When deciding upon
alarm locations, consider emergency power circuits,
Engineering Control Center data relay interface locations,
and the facility's established procedures for monitoring
alarm signals. Provide the following on plumbing drawings:
a.
Low voltage wiring and pressure switches associated
with master alarm signals and panels (on floor plans).
b.
Low voltage wiring diagram associated with master
alarm signals and panels.
c.
Tubing and/or communication cable runs from the sensor
locations to areas alarm panels (on floor plans and
medical gas and vacuum system diagrams).
