SECTION F-2702.0 DEFINITIONS
F-2702.1 General: The following words and terms shall, for the
purposes of this chapter and as stated elsewhere in this code, have
the meanings shown herein.
Bulk oxygen system: An assembly of equipment, such as oxygen
storage containers, pressure regulators, safety devices, vapor-
izers, manifolds and interconnecting piping, with a storage
capacity at normal temperature and pressure of the following:
1. More than 13,000 cubic feet (364 m') of oxygen con-
nected in service or ready for service.
2. More than 25,000 cubic feet (700 m') of oxygen, in-
cluding unconnected reserve at the site.
The bulk oxygen system terminates at the point where
oxygen at the service pressure first enters the supply line. The
oxygen is stored as liquid or gas in either stationary or portable
containers.
Ceiling limit: The maximum concentration of an air -borne con-
taminant to which a person is permitted to be exposed under
OSHA regulations. The permitted ceiling limits shall be in
accordance with DOL 29 CFR; 19 10. 1000 listed in Chapter
44.
Compressed gas: A gas or mixture of gases as contained having
an absolute pressure exceeding 40 psi at 70 degrees F. (276
kPa at 21 degrees C.) or, regardless of the pressure at 70
degrees F. (21 degrees C.), having an absolute pressure ex-
ceeding 140 psi at 130 degrees F. (965 kPa at 54 degrees C.);
or any liquid material having a vapor pressure exceeding 40
psi absolute at 100 degrees F. (276 kPa at 38 degrees C.) as
determined by ASTM D323 listed in Chapter 44.
Continuous gas detection system: A gas detection system
where the analytical instrument is maintained in continuous
operation and sampling is performed without interruption and
in which analysis is performed on a cyclical basis at intervals
not exceeding 30 minutes.
Excess flow valve: A valve inserted into a compressed gas
cylinder, portable or stationary tank designed to shut off
positively the flow of gas in the event the predetermined flow
from the cylinder or tank is exceeded.
Flammable anesthetic: A compressed gas which is flammable
and administered as an anesthetic, such as cyclopropane,
divinyl ether, ethyl chloride, diethyl ether and ethylene.
Flammable compressed gas: A compressed gas which forms a
flammable mixture when 13 percent or less (by volume) is
mixed with air or a compressed gas with a flammable range
with air that is wider than 12 percent, regardless of the lower
limitation. These limitations shall be determined at atmos-
pheric temperature and pressure.
Gaseous hydrogen system: A facility in which the hydrogen is
delivered, stored and discharged in the gaseous form to con-
sumer piping. The system includes stationary or movable
containers, pressure regulators, safety relief devices, mani-
folds, interconnecting piping and controls. The system termi-
nates at the point where hydrogen at service pressure enters
the consumer's distribution piping.
Immediately dangerous to life and health (IDLH): A concen-
tration of air -borne contaminant, normally expressed in parts
per million (ppm) or milligrams per cubic meter, which rep-
resents the maximum level from which an occupant is capable
of escaping within 30 minutes without any escape -impairing
symptoms or irreversible health effects.
Nesting: A method of securing flat-bottomed compressed gas
cylinders upright in a tight mass utilizing a contiguous three-
point contact system whereby all cylinders located within a
group have a minimum of three points of contact with other
cylinders, walls or bracing.
Nonflammable medical gas: A compressed gas which is non-
flammable and utilized for therapeutic purposes, such as
oxygen and nitrous oxide.

F-2704.1 General: The provisions of this section and the appli-
cable provisions of Sections F-2701.0 through F-2703.0 shall
apply to all new and existing buildings and outside areas occu-
pied for the storage, dispensing and use of highly toxic and toxic
compressed gases exceeding the exempt amounts per control
area indicated in Tables F-2701.3(2) and F-2701.3(5) unless
otherwise specified. The provisions of this section shall not apply
to existing structures occupied for the storage of toxic com-
pressed gases not constituting a distinct hazard to life or property.
F-2704.1.1 Breathing apparatus: Where highly toxic or
toxic compressed gases are stored, dispensed or used, a mini-
mum of two self-contained breathing apparatus shall be pro-
vided. Personnel shall be trained in self-contained breathing
apparatus operating procedures. The breathing apparatus shall
be compatible with the gases stored and used. The breathing
apparatus shall be stored near the immediate area of storage,
dispensing or use in a location providing safety to the users
of the apparatus. A safe area is a location that will not be
immediately affected by the release of highly toxic or toxic
compressed gases in the area of concern. Where self-con-
tained breathing apparatus alone provides inadequate protec-
tion due to the nature of gases present, other approved
protective equipment shall be provided.
F-2704.1.2 Gas cabinets: Gas cabinets, where provided,
shall be:
1. Operated at negative pressure relative to the surround-
ing area;
2. Provided with self-closing limited access ports or
noncombustible windows to provide access to equip-
ment controls. The average velocity of ventilation at the
face of access ports or windows shall not be less than
200 feet per minute (1 m/s) with a minimum of 150 feet
per minute (0.75 m/s) at any point of the access port or
window;
3. Operated so the exhaust ventilation is directed to a
treatment system;
4. Provided with self-closing doors;
5. Constructed of not less than a 0.1046 -inch (No. 12
Gage) steel; and
6. Shall not contain more than three cylinders unless the
cylinders have a net capacity of 1 pound (0.45 kg) or
less in which case the maximum number of cylinders
shall be limited to 100.
COMPRESSED GASES
F-2704.1.3 Exhausted enclosures: Exhausted enclosures.
where provided, shall be:
1. Constructed of approved noncombustible material and
shall consist of a top, back and two sides; and
2. Operated so the exhaust ventilation is directed to a
treatment system.
F-2704.1.4 Treatment systems: Treatment systems, where
provided to process the accidental release of gas, shall be in
accordance with items 1 through 5.
1. Treatment system processing: Treatment systems shall
process all exhaust ventilation discharged from gas
cabinets, exhausted enclosures and separate gas storage
rooms.
Exception: Treatment systems are not required for
toxic gases where:
1. Approved containment devices capable of fully
containing a release are available at an approved
location on site;
2. Trained personnel are available at an approved
location on site; and
3. Such containment devices are capable of being
transported to the leaking cylinder, portable tank
or stationary tank.
2. Treatment system design: Treatment systems shall be
capable of diluting, adsorbing, absorbing, containing,
neutralizing, burning or otherwise processing the en-
tire contents of the largest single tank or cylinder of
gas. Where a total containment system is utilized, the
system shall be designed to process the maximum
anticipated pressure of release to the system when the
system reaches equilibrium.
3. Treatment system performance: Treatment systems
shall be designed to reduce the maximum allowable
discharge concentration of the gas to one-half IDLH
at the point of discharge to the atmosphere. Where
more than one gas is emitted to the treatment system,
the treatment system shall be designed to process the
worst-case release based on the release rate, quantity
and IDLH for all gases.
4. Stationary tanks: Stationary tanks shall indicate the
maximum rate of release for the contained gas based
on any valves or fittings inserted directly into the tank.
Where multiple valves or fittings are provided, the
maximum flow rate of release for the valve or fitting
with the highest flow rate shall be indicated. Where
liquefied gases are in contact with any valve or fitting,
the liquid flow rate shall be utilized for computation
purposes. All flow rates indicated on the label shall be
converted to cubic feet per minute of gas at a normal
temperature and pressure.
5. Portable tanks and cylinders: The maximum flow rate
of release for portable tanks and cylinders shall be
calculated based on the total release from the cylinder
or tank within the time indicated in Table F-2704.1.4.
Where portable tanks or cylinders are equipped with
approved excess flow or reduced flow valves, the
worst-case release shall be determined by the maxi-
mum achievable flow from the valve in accordance
