systems, shall be in accordance with NFPA 54, 58, and 59A (references 9o,
9p and 9q) as applicable.
Medical Gas Systems. Medical gas systems include: compressed

air for medical and dental patient and laboratory use; vacuum for medical
and dental patient use, laboratory dust collection, waste anesthesia gas
disposal; and gases for patient, laboratory, and equipment use. See Table
9-4 for general information. Medical gas systems shall be designed to be
safe, reliable, and maintainable.

Systems for Medical Clinics. Centrally piped medical

gas/air/vacuum systems are not normally required or authorized for
outpatient medical treatment clinics. If attached to an existing
facility having central systems, Designers shall consider the feasibility
of extending service lines to the clinic if life cycle cost effective.
Dental Clinics. Centrally piped systems shall normally be

provided for dental compressed air (DCA), high volume oral evacuation
(DLV), high vacuum oral evacuation (DHV), high volume evacuation for
laboratory dust use (LDE); dental laboratory air (LA), and surgical
handpiece drive air (SHDA) as required to support the planned functions.
A separate system for Waste Anesthesia Gas Disposal (WAGD)may be required
unless the Using Agency designates the DHV or DLV system for that
purpose. Fuel gas (natural or propane) shall be provided as required to
