General Considerations for Hyperbaric Oxygen Supply

Compliance NFPA-50, NFPA-55, requirements:
A hyperbaric oxygen facility consists of a pressurized chamber • Must conform to installation siting requirements
and related equipment used for medical procedures performed • All equipment must be designed and cleaned for oxygen
at pressures above normal atmospheric pressure.
Hyperbaric (HBO) facilities must comply with standards published service
by the National Fire Protection Association in their pamphlets or • Piping must be tested
standards NFPA-50, NFPA-99, NFPA-55, NFPA-101 as well as
Guidelines published by the Compressed Gas Association in CGA CGA M-1 Requirements:
M-1. Review the issues related to HBO compliance before install- • Reserve supply for all installations
ing or making changes to a facility. • Alarms as specified by NFPA-99

facility nor does it identify the most significant or material risks
Scenario #2 associated with such installation.
Installation of a Hyperbaric Facility tied into an existing oxygen
supply system IF SUPPLIED AT THE SAME PRESSURE AS THE
EXISTING SYSTEM, both the main oxygen source of supply and
the reserve must be evaluated to ensure they are properly sized
to supply the additional volume to the facility, without jeopardiz-
ing the existing pressure and flow requirements of oxygen to
the patients, and the minimum 24hr reserve supply required by
NFPA. IF SUPPLIED AT A DIFFERENT PRESSURE (usually higher),
then
1. The existing source of supply and reserve must be adequately

sized to support the additional volumes (as above), and
2. A separate auxiliary dual-line regulator module/control cabi-

net with individual alarms must be located downstream of the
reserve supply, or
3. A dedicated source of supply and reserve must be installed.

Other Typical Gas Related Issues to be aware of:
In the NFPA’s Standards, particular reference to the following is-
sues should be considered. NFPA-99 Chapter 20 and NFPA-101:
• Shut-off valves must be installed at the point of entry to the

chamber rooms.
• Storage and handling must meet the applicable NFPA-99

Chapter 5 requirements.
• The bulk installation must meet NFPA-50 requirements.
