NFPA 99 “Health Care Facilities Code”, is updated by the “NFPA
Technical Committee” approximately every three years. (The
latest version, 2012 Edition “Health Care Facility Code” was
released in October 2011 and is widely viewed as the most
comprehensive medical gas system document with patient
safety at its highest).
NFPA 99 is adopted by states, most commonly through, the
Centers for Medicare & Medicaid Services(CMS) adoption of
NFPA 101 Life Safety Code

Chapter 18 NEW HEALTH CARE OCCUPANCIES
18.3.2.4 Medical Gas.
Medical gas storage and administration areas shall be
protected in accordance with NFPA 99, Standard for
Health Care Facilities.
Minnesota and Wisconsin have adopted NFPA 101 -2000 . Because a
code document cannot reference a newer version than the year of it’s
issuance, NFPA 99 – 1999 is considered the enforceable code document.

CMS has started the process of adopting NFPA 101-2012 Life
Safety Code (in the statement announcing this, they also
identified that this would include the newer version of NFPA 992012
• NFPA typically issues a new version of NFPA 99 every three years.
This version was delayed several years due to some changes to the
layout of the document.
• They removed some of the Chapters and added other Chapter,
specifically Plumbing, and Heating, Ventilating, and Air
Conditioning (HVAC).
• The committee changed the building types from “Levels” to
“Categories”. This was to bring this document in line with other
NFPA codes.
• NFPA changed the name of NFPA 99 from “Health Care Facilities”
to “Health Care Facilities Code”. This was requested by
municipalities and other code writing agencies to allow them to
adopt this document more readily.
This presentation is not intended to identify all of the minor
changes within the NFPA 99 -2012 document, but rather the major
changes that will effect the designer in their day to day design of
healthcare facilities.
We recommend that you get a copy of NFPA 99 -2012 from
National Fire Protection Association (www.NFPA.org)
Mark Allen (a member of the NFPA 99 technical committee) also
has issued a document with the changes identified. This can be
downloaded from his company web page.
(www.beaconmedaes.com)
NFPA has also issued a new Handbook, in lieu of a NFPA 99C
document, that has additional technical committee comments to
help the designer understand the intent of the information within
the code.
NFPA 99 now identifies the four different building types as
Categories 1 thru 4.
• Category 1. Facility systems in which failure of such
equipment or system is likely to cause major injury or death of
patients or caregivers shall be designed to meet system
Category 1 requirements as defined in this code.
• Category 2. Facility systems in which failure of such
equipment is likely to cause minor injury to patients or
caregivers shall be designed to meet system Category 2
requirements as defined in this code.
• Category 3. Facility systems in which failure of such
equipment is not likely to cause injury to patients or
caregivers, but can cause patient discomfort, shall be
designed to meet system Category 3 requirements as
defined in this code.
• Category 4. Facility systems in which failure of such
equipment would have no impact on patient care shall be
designed to meet system Category 4 requirements as
defined in this code.
What do these categories mean?
Category 1. Hospitals, Surgery Centers
Category 2. Medical Office Buildings, Dialysis Treatment Centers,
Clinics, Oral Surgery Facilities (The key to determining if a facility is
Category 1 or 2, is what is the level of injury to patient or caregiver
if the system is lost. If the system is designed to Category 2, the
facility needs to have an emergency plan to deal with the loss of
medical air, medical vacuum, and WAGD.)
Category 3. Dental Facilities (Category 3 facilities only have
Oxygen, Nitrous Oxide, Dental Air, Dental Vacuum, WAGD
systems. If the facility requires additional gases, they should be
considered Category 1 or 2)
Category 4. Laboratories
NFPA 99 1.3.4 Patient Care Rooms
1.3.4.1 The governing body of the facility or its designee shall
establish the following areas in accordance with the type of
patient care anticipated and with the following definitions of
the classification:

body of the health care organization to designate
anesthetizing locations.
1.3.4.3 Wet Procedure Locations. It shall be the responsibility of
the governing body of the health care organization to
designate wet procedure locations.
(The engineer no longer has to guess where within the facility
these areas are located)
Application
1.3.1 This code shall apply to all health care facilities other than home care.
1.3.2.1 If the alteration, renovation, or modernization adversely impacts the existing
performance requirements of a system or component, additional upgrading shall be
required.

5.1.3.4 New
Controls (regulators and their associated valves and
gauges) can be mounted remotely from the source
equipment if all other rules are observed.
5.1.3.5.13.2 (6) and 5.1.3.5.14.2 (7) New
Requirement for clearance of 1m (3ft) around
all serviced elements (container, vaporizers and
regulating controls), including the EOSC.

Methods for protecting the wiring for alarms are
listed.
5.1.9.2.3 Change 5.1.9.2.3
Wiring for Master alarms is more completely detailed
5.1.9.3.5 New
Wiring must preserve non-interchangeability of
sensors.
This additional requirement reflects the fact that most
alarm installations today mount the sensor on the
pipe and wire to the panel (as opposed to piping to
the panel and mounting the sensors there). Therefore,
not only can the sensor be mounted on the wrong
pipe (a pneumatic cross connection), but the sensor
can be wired to the wrong alarm (an electrical cross
connection). This provision attempts to deal with this.
This has been a standard feature of Beacon Medæs
alarms since the 1980’s.
5.1.10.8 Clarification
Allowance for threads in jointing (see also 5.1.10.8)
are narrowly limited.
The use of threading as a jointing technique in the
pipeline is now strictly limited to the points where
indicators are attached to the piping (e.g. pressure
sensors, gauges) Threading is prohibited in all other
locations. A big change which allows this is the
elimination of the threaded check valve (see 5.1.4.11).
Note that this is one difference between piping on the
source side and the patient side of the source valves threading is common and entirely acceptable on the
source side.
5.1.10.10 New
Push fit connections (e.g. ProBite, SharkBite)
are prohibited in the pipeline. Under some
circumstances, they can be used on source
equipment.
Deleted 5.1.10.10.6
Branch piping takeoffs no longer must come out
above the centerline of the main.
5.1.10.11.6.3 New
Flexible connections in pipelines are defined and if
equal to these requirements, permitted.
5.1.10.11.10.3 New
Installers must be individually qualified. A qualified
person may not “supervise” unqualified people and
have them be qualified by proximity.
5.1.13.2 New (see also 5.1.13.4)
Maintenance, periodic testing and qualifications for
maintenance personnel
5.1.14 Category 1 Operation and
Management


With recent strict changes for qualification and
training of installers, the industry has identified that
the biggest problems reported with medical gases
have shifted from installations problems, to
inadequate maintenance.
The addition of this section strives to address all of
the major elements of a maintenance plan,
including goals, timing, and the work to be
included.
This section also identifies the qualifications of
persons maintaining medical gas systems.
5.1.14.1.4 The medical-surgical vacuum
and WAGD systems shall not be used for
nonmedical applications (e.g., vacuum
steam condensate returns).
 A.5.1.14.1.4 Other examples of prohibited
use of medical-surgical vacuum would be
scope cleaning, decontamination, and
laser plume.

This booklet will focus on the changes to Chapter 5
respecting medical gas and vacuum, and within that,
Category 1 and 2 systems. It will attempt to detail the
scope of a change as well as our view of the justification
behind and impact of the change. Where a particular
risk in implementing a change exists, we will attempt to
describe the risk and offer some ideas on managing it.
The reader should please understand that comments
here represent the opinion of the author and are not
necessarily that of NFPA or of the committee in general
