FIELD OF TECHNOLOGY
[0001] This disclosure relates generally to the technical fields of safety systems and,
in one example embodiment, to a breathable air safety system having an air storage
sub-system.
BACKGROUND
[0002] A structure may include a horizontal building structure such as a shopping mall,
a warehouse, storage and manufacturing facilities, large box stores such as IKEA,
Home Depot, a vertical structure such as a high rise building, a mid rise building,
and a low rise building, a mine, a subway, a tunnel, and/or a wine cave.
[0003] The tunnel, for example, may be substantially horizontal and have a ratio of the
length of the passage to the width of at least two to one. In addition, the tunnel
may be completely enclosed on all sides, and the openings may be saved for the length
of the covered area causing limited accessibility to the tunnel.
[0004] Providing and maintaining adequate safety in the structure may be of importance.
For example, serious or fatal accidents occurring in underground mines in United States
over the years may have resulted from an inability to control roofs of the underground
mines. A fatal accident can occur, for example, from falling of even one large rock
from the roof of the mine.
[0005] In a case of an emergency situation of the structure, emergency personnel (e.g.,
a fire fighter, a SWAT team, a law enforcer, and/or a medical worker, etc.) may be
deployed onsite of the structure to alleviate the emergency situation through mitigating
a source of hazard as well as rescuing stranded civilians from the structure The emergency
situation may include events such as a fire, a chemical attack, a terror attack, a
subway accident, a mine collapse, and/or a biological agent attack.
[0006] In such situations, breathable air inside the structure may be hazardously affected
(e.g., depleted, absorbed, and/or contaminated). In addition, flow of fresh air into
the structure may be significantly hindered due to the structure having enclosed regions,
lack of windows, and/or high concentration of contaminants, etc. As a result, inhaling
air in the structure may be extremely detrimental and may further result in death
(e.g., within minutes). Furthermore, emergency work may often need to be performed
from within the structure.
[0007] The emergency personnel's ability to alleviate the emergency in an efficient manner
may be significantly limited by the lack of breathable air and/or abundance of contaminated
air. A survival rate of stranded civilians in the structure may substantially decrease
due to a propagation of contaminated air through out the structure, placing a large
number of innocent lives at significant risk.
[0008] As such, the emergency personnel may utilize a portable breathable air apparatus
(e.g., self-contained breathable air apparatus) as a source of breathable air during
an emergency incident and/or a rescue mission. However, the portable breathable air
apparatus may be heavy (e.g., 9kg-13,6kg (20-30 pounds)) and/or may provide breathable
air for a short while (e.g., approximately 15-30 minutes). In the emergency situation,
the emergency personnel may need to walk, descend and/or climb to a particular location
within the structure to perform rescuing work due to inoperable transport systems
(e.g., obstructed walkway, elevators, moving sidewalks, and/or escalators, etc.)
[0009] As such, by the time the emergency personnel reach the particular location, his/her
portable breathable air apparatus may be already depleted and may require replenishment
(e.g., via a shuttle method or returning back to a previous location for a new portable
breathable air apparatus). As a result, precious lives may be lost due to precious
time being lost. An extra supply of portable breathable air apparatuses may be stored
throughout the structure so that emergency personnel can replace their portable breathable
air apparatuses within the structure. However, supplying structures with spare portable
breathable air apparatuses may be expensive and take up space in the structure, thereby
causing severe handicap to the ability of emergency personnel to perform rescue tasks.
[0011] Furthermore, management, supervisors, personnel, etc., may not regularly inspect
the spare portable breathable air apparatuses. With time, the spare portable breathable
air apparatuses may experience pressure loss placing the emergency personnel at significant
risk when the spare breathable air apparatus is utilized in the emergency situation.
The spare portable breathable air apparatuses may also be tampered with, during storage.
Contaminants may be introduced into the spare portable breathable air apparatuses
that may be detrimental to the emergency personnel.

[0013] The safety system may further include a safety relief valve of any of the supply
unit and the fill station to release the breathable air when a system pressure of
the air distribution system exceeds a threshold value beyond the design pressure to
ensure reliability of the air distribution system through maintaining the system pressure
such that it is within a pressure rating of each component of the air distribution
system.
[0014] The safety system may also include a CGA connector and RIC/UAC connector of the supply

fire alarm system of the building structure such that the fire alarm system is set
off when the system pressure of the air distribution system is outside a safety range.
The pressure switch may electrically transmit a warning signal to an emergency supervising
station when the system pressure of the air distribution system is outside the safety
range.
[0021] The fill station may have a physical capacity to enclose at least one breathable
air apparatus and may include a RIC/UAC connector that expedites a filling process
of the breathable air apparatus. The safety system may further include a tamper switch
of the locking mechanism of the supply unit enclosure such that an alarm is automatically
triggered and a signal is electrically coupled to any of relevant administrative personnel
of the building structure and the emergency supervising station when an intrusion
of the supply unit occurs. The secure chamber may be certified to be rupture containable
according to approved standards. The safety system may also include a selector valve
that is accessible by emergency personnel to selectively utilize the source of compressed
air to deliver the breathable air to the air fill station.
[0022] The air storage sub-system may be housed in a fire rated enclosure that is certified

is replenishable with a source of compressed air.
[0024] In addition, the method may include preventing corrosion and physical damage due
to weather by incorporating a supply unit enclosure that is weather resistant. The
method may further include preventing intrusion of the supply unit potentially compromising
the safety and reliability of the breathing emergency support system by incorporating
a locking mechanism of the supply unit enclosure. The method may also include minimizing
physical damage of various external hazards to protect the supply unit and the fill
site from any of an intrusion and damage through utilizing a robust metallic material
to the supply unit enclosure.
[0025] The method may include preventing leakage of air from the emergency support system
leading to a potential pressure loss of the emergency support system through utilizing
a valve of any of the supply unit and the fill site. The method may further include
discontinuing transfer of the breathable air from the source of compressed air to
the emergency support system through utilizing a valve to the emergency support system.
In addition, the method may include automatically releasing the breathable air from
the emergency support system when the system pressure of the emergency support system

unit and/or the fill site. The method may also include ensuring compatibility of the
emergency support system and the source of compressed air of an authority agency through
a CGA connector and/or a RIC/UAC connector of the supply unit.
[0026] In addition, the method may include adjusting a fill pressure to ensure that the
fill pressure of the source of compressed air does not exceed the prescribed pressure
of the emergency support system through a pressure regulator of the supply unit. The
method may further include monitoring the system pressure of the emergency support
system and/or the fill pressure of the source of compressed air through a pressure
gauge of the supply unit enclosure. The method may also include improving accessibility
of the supply unit enclosure through providing luminescence in reduced light environment
by incorporating a visible marking. In addition, the method may include isolating
a fill site from a remaining portion of the emergency support system using an isolation
valve of the fill site such that the remaining portion of the emergency support system
is utilizable in an emergency situation.
[0027] The method may further include automatically actuating the isolation valve based
on an air pressure sensor of the emergency support system. The method may also include

not exceed the pressure rating of the breathable air apparatus through a pressure
regulator of the fill site. In addition, the method may include monitoring any one
of the fill pressure of the fill site and the system pressure of the emergency support
system by incorporating the pressure gauge to the fill site.
[0028] The method may further include enabling the distribution structure to withstand elevated
temperatures for a period of time using a fire rated material to encase the distribution
structure. The method may include preventing the fire rated material from any damage
by incorporating a sleeve at least three times an outer diameter of each pipe of the
distribution structure exterior to the fire rated material.
[0029] The method may also include preventing physical damage to the distribution structure
potentially compromising safety and integrity of the emergency support system by utilizing
a robust solid casing of the distribution structure. In addition, the method may include
protecting the robust solid casing from any damage using another sleeve at least three
times an outer diameter of a pipe of the distribution structure exterior to the robust
solid casing.
[0030] The method may also include automatically tracking and recording any impurities and
contaminants in the breathable air of the breathing emergency support system through

air dissemination to the fill sites in a case that any of an impurity level and contaminant
concentration exceeds a safety threshold. In addition, the method may include tracking

[0056] In a next embodiment, a method of safety of a building structure includes ensuring
that a prescribed pressure of an emergency support system (e.g.,. the air distribution
system 150, 250, 350 of
Figures 1-3) maintains within a threshold range of the prescribed pressure by including a valve
of the emergency support system to prevent leakage of breathable air from the emergency
support system (e.g., the air distribution system 150, 250, 350 of
Figures 1-3), safeguarding a filling process of a breathable air apparatus by enclosing the breathable
air apparatus in a secure chamber .(e.g., the holders 612 of
Figure 6A) of a fill site (e.g., the fill site 102 of
Figures 1-3) of the emergency support system 150 of the building structure to provide a safe placement
to supply the breathable air to the breathable air apparatus, and maintaining the
prescribed pressure of the emergency support system 150 such that a system pressure
is compatible with the breathable air apparatus through a distribution structure that
is rated for use with compressed air that couples the supply unit and the fill site
102 to transfer breathable air of the source of compressed air to the fill site 102.
[0057] In another embodiment, a building structure (e.g., a horizontal building structure
such as a shopping mall, a vertical building structure such as a high rise building,
a mid rise building, and/or a low rise building, a mine, a subway, and/or a tunnel,
etc.) includes a first set of walls extending vertically and horizontally enclosing

structure, a second set of walls that divide the internal region of the building structure
in any of a horizontal and vertical direction into rooms displaced any of a horizontally
and vertically from one another, a supply unit (e.g., the supply unit 100 of
Figures 1-3) adjacent to a particular wall of the first set of walls to facilitate delivery of
breathable air from a source of compressed air to an emergency support system (e.g.,
the air distribution system 150, 250, 350
of Figures 1-3) of the building structure, a fill station (e.g., the fill station 102A of
Figure 6A) of the internal region of the building structure to provide the breathable air to
a breathable air apparatus at multiple locations of the building structure, a secure
chamber (e.g., the holders 612 of
Figure 6A) of the fill station 102A as a safety shield that confines a possible rupture of an
over-pressurized breathable air apparatus within the secure chamber 612, and a distribution
structure (e.g., the distribution structure 104 of
Figures 1-3) that is compatible with use with compressed air that facilitates dissemination of
the breathable air of the source of compressed air to multiple locations of the building
structure.
[0058] In yet another embodiment, a safety system of a building structure includes a supply
unit (e.g., the supply unit 100 of
Figures 1-3) of a building structure to facilitate delivery of breathable air from a source of
compressed air to an air distribution system (e.g., the air distribution system 150,250,350
of
Figures 1-3) of the building structure, a valve to prevent leakage of the breathable air from
the air distribution system potentially leading to loss of system pressure, a fill
panel (e.g., the fill panel 102B of
Figure 6) interior to the building structure having a RIC/UAC fitting pressure rated for a
fill outlet of the fill panel to fill a breathable air apparatus to expedite a breathable
air extraction process from the air distribution system and to provide the breathable
air to the breathable air apparatus at multiple locations of the building structure,
and a distribution structure (e.g., the distribution structure 104 of
Figures 1-3) that is compatible with use with compressed air that facilitates dissemination of
the breathable air of the source of compressed air to multiple locations of the building
structure.
[0059] In a further embodiment, a method of safety of a structure includes ensuring that
a prescribed pressure of the emergency support system 150 maintains within a threshold
range of the prescribed pressure by including a valve of the emergency support system
to prevent leakage of breathable air from the emergency support system, and expediting
an air extraction process from the emergency support system by including a RIC/UAC
fitting to a fill panel to fill a breathable air apparatus.
[0060] In yet a further embodiment, a building structure includes a first set of walls extending
vertically and horizontally enclosing an area of land such that the area of land is
in the internal region of the building structure, a second set of walls that divide
the internal region of the building structure in any of a horizontal and vertical
direction into areas displaced any of a horizontally and vertically from one another,
a supply unit (e.g., the supply unit 100 of
Figures 1-3) adjacent to a particular wall of the first set of walls to facilitate delivery of
breathable air from a source of compressed air to an emergency support system (e.g.,
the air distribution system 150, 250, 350 of
Figures 1-3) of the building structure, a fill panel of the internal region of the building structure
having a RIC/UAC fitting to expedite a breathable air extraction process from the
emergency support system and to provide the breathable air to the breathable air apparatus
at multiple locations of the building structure, and a distribution structure (e.g.,
the distribution structure 104 of
Figures 1-3) that is compatible with use with compressed air that facilitates dissemination of
the breathable air of the source of compressed air to multiple locations of the building
structure.
[0061] In a subsequent embodiment, a safety system of a mine structure includes a supply
unit (e.g., the supply unit 100 of
Figures 1-3) of a mine structure to facilitate delivery of breathable air from a source of compressed
air to an air distribution structure (e.g., the distribution structure 104 of
Figures 1-3) of the mine structure, a valve (e.g., the check valve of a series of valves 408
of Figure 4) to prevent a leakage of the breathable air from the air distribution structure 150
potentially leading to loss of a system pressure, a fill site (e.g., the fill site
102 of
Figures 1-3) interior to the mine structure to provide the breathable air to a breathable air
apparatus at multiple locations of the mine structure, and a distribution structure
(e.g., the distribution structure 104 of
Figures 1-3) that is compatible with use with compressed air that facilitates dissemination of
the breathable air of the source of compressed air to multiple locations of the mine
structure.
[0062] In yet another embodiment, a method of safety of a mine structure includes ensuring
that a prescribed pressure of the emergency support system 150 maintains within a
threshold range of the prescribed pressure by including a valve of the emergency support
system to prevent leakage of breathable air from the emergency support system 150,
safeguarding a filling process of a breathable air apparatus by enclosing the breathable
air apparatus in a secure chamber (e.g., the holders 612 of
Figure 6A) of a fill site (e.g., the fill site.102 of
Figures 1-3) of the emergency support system 150 of the mine structure to provide a safe placement
to supply the breathable air to the breathable air apparatus, and providing a spare
storage of breathable air through an air storage tank (e.g., the air storage tanks
1008 of
Figure 10) of a storage sub-system (e.g., the air storage sub-system 950 of
Figure 10) to store breathable air that is replenishable with a source of compressed air.
[0063] Figure 1 is a block diagram of an air distribution system 150 in a structure, according to
one embodiment. The air distribution system 150 may include any number of supply units
100, any number of fill sites 102 that are coupled to the rest of the air distribution
system 150 through a distribution structure 104. The air distribution system 150 may
also include an air monitoring system 110 having a CO/Moisture sensor 106 and a low
pressure sensor 108.
[0064] The supply unit 100 may be placed at a number of locations exterior to the structure
(e.g., a horizontal building structure such as a shopping mall, a vertical building
structure such as a high rise building, a mid rise building, and/or a low rise building,
a mine, a subway, and/or a tunnel structure, etc.) to allow ease of access by a source
of compressed air and/or to expedite supplying the air distribution system 150 with
breathable air. The supply units 100 may also be placed at locations that are substantially
free of traffic to decrease potential obstruction present in an emergency situation
(e.g., a building fire, a chemical attack, terror attack, subway accident, mine collapse,
and/or a biological agent attack, etc.).
[0065] The fill sites 102 may also be placed at a number of locations of the structure (e.g.,
a horizontal building structure such as a shopping mall, a vertical building structure
such as a high rise building, a mid rise building, and/or a low rise building, a mine,
a subway, and/or a tunnel, etc.) to provide the breathable air to a breathable air
apparatus at multiple locations (e.g., at multiple access points) of the structure.
In one embodiment, the fill sites 102 may include wireless capabilities (e.g., a wireless
module 114) for communication with remote entities (e.g., the supply unit 100, building
administration, and/or an authority agency, etc.).
[0066] The distribution structure 104 may have any number of fill sites 102 (e.g., the fill
panel 102B and/or the fill station 102A) on each floor and/or different floors. Each
fill site 102 may be sequentially coupled to one another and to the supply units 100
through the distribution structure 104. The distribution structure 104 may include
any number of pipes to expand an air carrying capacity of the air distribution system
150 such that breathable air is replenished with a source of compressed air at a higher
rate.
[0067] The air monitoring system 110 may contain multiple sensors such as the CO/Moisture
sensor 106 and the pressure sensor 108 to track and record quality of the breathable
air (e.g., like impurity levels and contaminants concentration, etc.) in the air distribution
system 150. Since emergency personnel (e.g., a fire fighter, a SWAT team, a law enforcer,
and/or a medical worker, etc.) depend on the breathable air distributed via the air
distribution system 150, it is essential that quality of the breathable air be constantly
maintained. The air monitoring system 110 may also include other sensors that detect
other hazardous substances (e.g., benzene, acetamide, acrylic acid, asbestos, mercury,
phosphorous, propylene oxide, etc.) that contaminates the breathable air.
[0068] In one embodiment, the distribution structure 104 that is compatible to use with
compressed air may facilitate dissemination of the breathable air of the source of
compressed air to multiple locations of the structure. A fire rated material (e.g.,
the fire rated material 702 of
Figure 7A) may encase the distribution structure 104 such that the distribution structure 104
has the ability to withstand elevated temperatures for a prescribed period of time.
The pipes of the distribution structure 104 may include a sleeve exterior to the fire
rated material 702 to protect the fire rated material 702 from damage. Both ends of
the sleeve may be fitted with a fire rated material 702 approved by an authority agency
(e.g., certified according to the approved standards). In addition, the distribution
structure 104 may include a robust solid casing to prevent physical damage to the
distribution structure 104 potentially compromising safety and reliability of the
air distribution system 150.
[0069] The distribution structure 104 may include support structures at specific intervals
(e.g., less than five feet) to provide adequate structural support for each pipe of
the distribution structure 104. The pipes and the fittings of the distribution structure
104 may be of stainless steel, and thermoplastic material, etc. compatible to use
with compressed air.
[0070] In another embodiment, the air distribution system 150 may include an air monitoring
system 110 to automatically track and record impurity levels and/or contaminant concentration
in the breathable air of the air distribution system 150. The air monitoring system
110 may have an automatic shut down feature to discontinue air distribution to the
fill sites 102 in a case that any of an impurity level and contaminant concentration
exceeds a safety threshold. For example, a pressure monitoring system (e.g., the pressure
sensor 108 of
Figure 1) may automatically track and record the system pressure of the air distribution system
150. Further, a pressure switch may be electrically coupled to an alarm system (e.g.,
the fire alarm system) such that the alarm system is set off when the system pressure
of the air distribution system 150 exceeds the safety threshold.
[0071] Figure 2 is block diagram of an air distribution system in a structure having fill sites located
vertically from one another, according to one embodiment. In the air distribution
system 250, the distribution structure 104 may individually couple each fill site
102 (e.g., the fill panel 102B and/or the fill station 102A) to the supply unit 100.
Individual coupling may be advantageous in case one pipe of the distribution structure
104 becomes inoperable and/or unserviceable, the other pipes can still deliver air
to the fill sites 102 (e.g., the fill panel 102B and/or the fill station 102A).
[0072] In the air distribution system 250, the distribution structure 104 may sequentially
couple each fill site 102 (e.g., the fill panel 102B and/or the fill station 102A)
displaced predominantly vertically from the supply unit 100. Each air distribution
system 250 may be used in conjunction with one another depending on a particular architectural
style of the structure in a manner that provides efficient access to the breathable
air of the air distribution system 250 reliably.
[0073] Figure 3 is a block diagram of an air distribution system 350 in a structure (e.g., mines,
building, tunnel, etc.) having fill sites (e.g., the fill panel and/or fill stations,
etc.) located horizontally from one another, according to one embodiment. The air
distribution system 350 may include any number of supply units 100, any number of
fill sites 102 (e.g., a fill panel and/or a fill station, etc.) that are coupled to
the rest of the air distribution system 150 through a distribution structure 104.
The air distribution system 150 may also include an air monitoring system 110 having
a CO/Moisture sensor 106 and a pressure sensor 108. In the air distribution system
350, the distribution structure 104 may sequentially couple each fill site 102 (e.g.,
a fill panel and/or a fill station, etc.) displaced predominantly horizontally from
the supply unit 100. Each air distribution system 350 may be used in conjunction with
one another depending on the particular architectural style of the structure in a
manner that provides efficient access to the breathable air of the air distribution
system 350 reliably.
[0074] Figure 4A is a front view of the supply unit 100 of the air distribution system 150, according
to one embodiment. The supply unit 100 may provide accessibility of a source of compressed
air to supply breathable air to the air distribution system (e.g., the air distribution
system 150, 250, and/or 350 of
Figures 1-3). The supply unit 100 may include a fill pressure indicator 400, a fill control knob
402, a system pressure indicator 404, and a connector 406.
[0075] The supply unit 100 may include an adjustable pressure regulator of the supply unit
100 that is used to adjust a fill pressure of the source of compressed air to ensure
that the fill pressure does not exceed the safety threshold of the design pressure
of the air distribution system 150. Further, the supply unit 100 may also include
a pressure gauge (e.g., the fill pressure indicator 400, the system pressure indicator
404, etc.) of the supply unit enclosure 500 to indicate any of the system pressure
(e.g., through the system pressure indicator 404 of
Figure 4) of the air distribution system 150 and the fill pressure (e.g., through the fill
pressure indicator 400 of
Figure 4) of the source of compressed air.
[0076] The fill pressure indicator 400 may indicate pressure level at which breathable air
is being delivered by the source of compressed air to the air distribution system
150. The fill control knob 402 may be used to control the fill pressure such that
the fill pressure does not exceed a safety threshold of a design pressure of the air
distribution system 150. The system pressure indicator 404 may indicate current pressure
level of the breathable air in the air distribution system 150.
[0077] The connector 406 may be a CGA connector, a RIC/UAC connector (e.g., the RIC/UAC
connector 620
of Figure 6B) etc. which is compatible with an air outlet of the source of compressed air of various
emergency agencies (e.g., fire station, law enforcement agency, medical provider,
and/or SWAT team, etc.). The connector 406 (e.g., CGA connector, RIC/UAC connector
620, etc.) of the supply unit 100 may facilitate a connection with the source of compressed
air through ensuring compatibility of the supply unit 100 with the source of compressed
air. In one embodiment, the supply unit 100 of a building structure may facilitate
delivery of breathable air from a source of compressed air to the air distribution
system 150 of the building structure.
[0078] Figure 4B is a rear view of the supply unit 100 of the air distribution system 150, according
to one embodiment. The supply unit 100 also may include a series of valves 408 (e.g.,
a valve, an isolation valve, and/or a safety relief valve, etc.) to ensure that system
pressure is maintained within a safety threshold of the design pressure of the air
distribution system 150.
[0079] The supply unit 100 of a structure (e.g., building structure, tunnel structure, mine
structure, etc.) may facilitate delivery of breathable air from a source of compressed
air to the air distribution system 150 of the structure. The supply unit 100 may include
the series of valves 408 (e.g., the valve, and/or the safety relief valve, etc.) to
prevent a leakage of the breathable air from the air distribution system 150 potentially
leading to loss of system pressure. For example, the supply unit 100 may include a
valve of the series of valves 408 to automatically discontinue transfer of breathable
air from the source of compressed air to the air distribution system 150. The safety
relief valve of the supply unit 100 and/or the fill site 102 may release breathable
air when a system pressure of the air distribution system 150 exceeds a threshold
value of the design pressure to ensure reliability of the air distribution system
150 through maintaining the system pressure such that the system pressure is within
a pressure rating of each component of the air distribution system 150.
[0080] Figure 5 is an illustration of a supply unit enclosure 500 encompassing the supply unit 100,
according to one embodiment. The supply unit enclosure 500 may include a locking mechanism
502 to secure the supply unit 100 from unauthorized access. Further, the supply unit
enclosure 500 may also contain a fire rated material 702 such that the supply unit
100 withstands elevated temperatures for a prescribed period of time.
[0081] The supply unit enclosure 500 encompassing the supply unit 100 may have any of a
weather resistant feature, ultraviolet and/or infrared solar radiation resistant feature
to prevent corrosion and/or physical damage. The locking mechanism 502 may secure
the supply unit 100 from intrusions that potentially compromise safety and reliability
of the air distribution system 150.
[0082] In addition, the supply unit enclosure 500 may include a robust metallic material
to protect the supply unit 100 from any of an intrusion and damage due to various
hazards. For example, the robust metallic material may be substantially 18 gauge carbon
steel. The supply unit enclosure 500 may be provided with a visible marking to provide
luminescence in a reduced light environment. The locking mechanism 502 may also include
a tamper switch which automatically triggers an alarm and electrically communicates
a signal to any of administrative personnel of the structure and an emergency supervising
station when an intrusion of any of the supply unit 100 and the secure chamber 612
occurs.
[0083] Figure 6A is an illustration of the fill station 102A interior to the structure, according
to one embodiment. The fill station 102A may be a type of the fill site 102 of
Figure 1. The fill station 102A may include a system pressure indicator 600, a fill pressure
regulator 602, a fill pressure indicator 604, another fill pressure indicator 606,
and fill control knob 608. The fill station 102A may also include a RIC/UAC connector
610 and multiple breathable air apparatus holders 612 used to supply air from the
air distribution system 150. The fill station 102A may be a rupture containment chamber
such that over-pressurized compressed air cylinders are shielded and contained to
prevent injuries.
[0084] The system pressure indicator 600 may indicate current pressure level of breathable
air in the air distribution system 150. The fill pressure regulator 602 may enable
adjusting of a fill pressure of a source of compressed air to ensure that the fill
pressure does not exceed design pressure of the air distribution system 150. The fill
pressure indicator 604 and another fill pressure indicator 606 may indicate pressure
level at which breathable air is being delivered by the source of compressed air to
the air distribution system 150. The fill control knob 608 may be used to control
the fill pressure such that the fill pressure does not exceed a safety threshold for
which the air distribution system 150 is designed for.
[0085] The RIC/UAC connector 610 may facilitate direct coupling to an emergency equipment
to supply breathable air through a hose (e.g., connecting the RIC/UAC connector 610
and the emergency equipment). In essence, precious time may be saved because emergency
personnel may not need to spend time to remove the emergency equipment from their
rescue attire before they can be supplied with breathable air. Further, the RIC/UAC
connector 610 may also directly couple to a face-piece of a respirator to supply breathable
air.
[0086] The multiple breathable air apparatus holders 612 can hold multiple compressed air
cylinders to be filled simultaneously. In addition, the multiple breathable air apparatus
holders 612 can be rotated in order that additional compressed air cylinders may be
loaded while the multiple compressed air cylinders are filled inside the fill station
102A.
[0087] In one embodiment, the fill station 102A interior to a structure (e.g., building
structure, tunnel structure, mine structure, etc.) may provide breathable air to a
breathable air apparatus at multiple locations of the structure. A secure chamber
(e.g., the holders 612 of
Figure 6A) of the fill station 102A may be a safety shield that confines a possible rupture
of an over-pressurized breathable air apparatus within the secure chamber 612. The
fill station 102A may include a valve to prevent leakage of air (e.g., potentially
leading to pressure loss of the air distribution system) from the air distribution
system 150 through ensuring that the system pressure is maintained within a threshold
range of design pressure to reliably fill the breathable air apparatus. An isolation
valve may be included to isolate a breathable fill station from a remaining portion
of the air distribution system 150.
[0088] The isolation valve may be automatically actuated through an air pressure sensor
(e.g., the low pressure sensor 108 of
Figure 1) of the air distribution system 150. The fill station 102A may include a pressure
regulator to adjust a fill pressure to fill the breathable air apparatus and/or to
ensure that the fill pressure does not exceed the pressure rating of the breathable
air apparatus potentially resulting in a rupture of the breathable air apparatus.
The fill station 102A may include a pressure gauge (e.g., the system pressure indicator
600, the fill pressure indicator 604, and another fill pressure indicator 606) to
indicate any of a fill pressure (e.g., the fill pressure indicator 604, 606) of the
fill station 102A and a system pressure (e.g., the system pressure indicator 600)
of the air distribution system 150.
[0089] In one embodiment, the air fill station 102A may have a physical capacity to enclose
the breathable air apparatus and include the RIC/UAC connector 610 to facilitate a
filling of the breathable air apparatus. The fill station 102A may also include a
securing mechanism of the secure chamber 612 having a locking function which is automatically
actuated through a coupling mechanism (e.g., with a flow switch) that indicates a
status of air flow to the breathable air apparatus fillable in the fill station 102A.
[0090] Figure 6B is an illustration of a fill panel 102B interior to the structure, according to one
embodiment. The fill panel 102B may include a fill pressure indicator 614 (e.g., pressure
gauge), a fill control knob 616 (e.g., pressure regulator), a system pressure indicator
618, a number of RIC/UAC connectors 620 and fill hoses 622. The fill panel 102B may
also include a fill panel enclosure 624 with a locking mechanism to secure the fill
panel 102B from intrusions that potentially compromise safety and reliability of the
air distribution system 150. The system pressure indicator 618 may indicate current
pressure level of breathable air in the air distribution system 150. The fill control
knob 616 may be used to adjust fill pressure such that the fill pressure does not
exceed a safety threshold for which the air distribution system 150 is designed for.
[0091] The RIC/UAC fitting 620 may facilitate direct coupling to emergency equipment to
supply breathable air through a hose (e.g., connecting the RIC/UAC fitting 620 and
the emergency equipment). Further, the RIC/UAC fitting 620 connected with the fill
hoses 622 may also directly couple to a face-piece of a respirator to supply breathable
air to emergency personnel (e.g., a fire fighter, a SWAT team, a law enforcer, and/or
a medical worker, etc.) and/or stranded survivors in need of breathing assistance.
Each fill hose 622 may be designed for different pressure rating and may be couple-able
to any of a self-contained breathable air apparatus and respiratory mask through the
compatible RIC/UAC connector 620. The fill panel enclosure 624 may be provided with
a visible marking to provide luminescence in a reduced light environment.
[0092] In one embodiment, the fill panel 102B interior to a structure (e.g., tunnel structure,
mine structure, building structure, etc.) may have a RIC/UAC fitting 620 to fill a
breathable air apparatus to expedite a breathable air extraction process from the
air distribution system 150 and/or to provide the breathable air to the breathable
air apparatus at multiple locations of the structure. The fill panel 102B may include
a safety relief valve set to have an open pressure (e.g., of at most approximately
10% more than a design pressure) of the air distribution system 150 to ensure reliability
of the air distribution system 150 through maintaining the system pressure such that
the system pressure is within a threshold range of a pressure rating of each component
of the air distribution system 150. For example, the fill panel enclosure 624 may
be made from 18 gauge carbon steel to minimize physical damage due to various naturally
occurring and man-imposed hazards through protecting the fill panel from any of an
intrusion and damage. The fill panel 102B may include an isolation valve to isolate
a damaged fill panel 102B from a remaining operable portion of the air distribution
system 150.
[0093] Figure 7A is a diagrammatic view of a pipe of the distribution structure 104 in a fire rated
material 702, according to one embodiment. The distribution structure 104 having pipes
may be enclosed in the fire rated material 702. The fire rated material 702 may prevent
the distribution structure 104 from damage (e.g., due to fire) such that the air distribution
system 150 may be operational for a longer time period in an emergency situation (e.g.,
building fire, chemical attack, terror attack, subway accident, mine collapse, and/or
a biological agent attack, etc.).
[0094] Figure 7B is a cross sectional view 700 of the distribution structure 104 embedded in a fire
rated material 702, according to one embodiment. Section 700 is a cross section of
the distribution structure 104 embedded in the fire rated material 702.
[0095] Figure 8 is a network view of an air monitoring system 806 with a wireless module 808 communicating
with a building administration 802 and an authority agency 804 through a network 810,
according to one embodiment. The air monitoring system 806 may include various sensors
(e.g., the CO/Moisture sensor 106 of
Figure 1, the pressure sensor 108 of
Figure 1, and/or hazardous substance sensor, etc.) and/or status indicators regarding system
readiness information (e.g., system pressure, in use, not in use, operational status,
fill site usage status, fill site operational status, etc.).
[0096] The air monitoring system 806 may communicate sensor readings to a building administration
802 (e.g., building management, security, and/or custodial services, etc.) such that
proper maintenance measures may be taken. The air monitoring system 806 may also send
alert signals (e.g., as a reminder) for regular system inspection and maintenance
to the building administration 802 through the network 810. The air monitoring system
806 may also communicate sensor readings to an authority agency 804 (e.g., a police
station, a fire station, and/or a hospital, etc.). The wireless module 808 may be
a device which communicates with other devices to enable the air monitoring system
806 monitor the air distribution system 150.
[0097] Figure 9 is a front view of a control panel 900 of an air storage sub-system 950, according
to one embodiment. The control panel 900 includes a fill pressure gauge 902, a storage
pressure gauge 904, a booster pressure gauge 906, a system pressure gauge 908 and
a storage bypass knob 910. The fill pressure gauge 902 may indicate pressure level
at which breathable air is being delivered by the source of compressed air to the
air distribution system (e.g., an air distribution system 150, 250, and/or 350 of
Figures 1-3). The storage pressure gauge 904 may display pressure level of air storage tanks
in the air storage sub-system 950.
[0098] The booster pressure gauge may display pressure level of a booster tank (e.g., the
booster tank 1006 of
Figure 10). The system pressure gauge 908 may indicate current pressure level of the breathable
air in the air distribution system 150 recorded by the pressure monitoring system.
Air stored in the air storage sub-system 950 may be directly supplied to the air distribution
system 150 through.utilizing the storage bypass knob 910.
[0099] Figure 10 is an illustration of the air storage sub-system 950, according to one embodiment.
Particularly,
Figure 10 illustrates the control panel 900, tubes 1000, a driver air source 1002, a pressure
booster 1004, a booster tank 1006, and air storage tanks 1008, according to one embodiment.
The control panel 900 may provide status information associated with storage pressure,
booster pressure, pressure of the compressed air source, and the system pressure of
the air storage sub-system 950. The tubes 1000 having a looped configuration may couple
each air storage tank 1008 to one another. The looped configuration of the tubes 1000
may increase in robustness of the tubes 1000 and thus may prevent damage of the tubes
1000 due to stress. In one example embodiment, the control panel 900 is mounted on
the tubes 1000 coupled to the air storage tank 1008 and the booster tank 1006.
[0100] The driving air source 1002 may be used to pneumatically drive the pressure booster
1004 to maintain a higher pressure in the air distribution system 150 such that a
breathable air apparatus is reliably filled. For example, a supply of breathable air
in the air storage tanks 1008 may be conserved through utilizing a driving air source
1002 to drive the pressure booster 1004.
[0101] In addition, the driving air source 1002 enables the breathable air to be optimally
supplied to the structure (e.g., mine, tunnel, building, etc.) through allowing the
breathable air to be isolated from driving the pressure booster 1004. The booster
tank 1006 may store air at a higher pressure than the air stored in the air storage
tanks 1008 to ensure that the air distribution system is constantly supplied with
breathable air sufficiently pressurized to fill a breathable air apparatus.
[0102] In one embodiment, the air storage sub-system 950 may include air storage tanks 1008
to provide storage of air that is dispersible to multiple locations of the structure
(e.g., building structure, tunnel structure, mine structure, etc.). The air storage
tanks 1008 of the air storage sub-system 950 may be coupled to each other through
tubes 1000 (e.g., having a looped configuration) to increase robustness of the tubes
1000 to prevent breakage due to stress. In addition, a booster tank 1006 of the air
storage sub-system 950 may be coupled to the air storage tanks 1008 to store compressed
air of a higher pressure than the compressed air that is stored in the air storage
tank 1008. A driving air source 1002 of the air storage sub-system 950 may be coupled
to the pressure booster 1004 to pneumatically drive a piston of the pressure booster
1004 to maintain a higher pressure of the air distribution system 150 such that a
breathable air apparatus is reliably filled.
[0103] ] Further, the driving air source 1002 may enable the breathable air to be optimally
supplied to the structure (e.g., through allowing the breathable air to be isolated
from driving the pressure booster 1004). The air storage sub-system 950 may also include
an air monitoring system (e.g., that includes the CO/Moisture sensor 106 of
Figures 1-3) to automatically track and record any of impurities levels and contaminants concentration
in the breathable air of the air distribution system 150. The air monitoring system
110 may include an automatic shut down feature to discontinue air dissemination to
the fill station 102A when any of impurity level and contaminant concentration exceeds
a safety threshold. The air storage sub-system 950 may also include a pressure monitoring
system (e.g., a pressure sensor 108 of
Figure 1) to continuously track and record the system pressure of the air distribution system
150.
[0104] A pressure switch may be electrically coupled to an alarm system such that the alarm
system is set off when the system pressure of the air distribution system 150 exceeds
a safety threshold. The pressure switch may electrically transmit a warning signal
to an emergency supervising station when the system pressure of the air distribution
system 150 is below the prescribed level.
[0105] The air storage sub-system 950 may include an indicator unit to provide status information
of the air distribution system 150 associated with storage pressure, booster pressure,
pressure of the compressed air source, and/or the system pressure, etc. Further, the
air storage sub-system 950 may also include a selector valve accessible by an emergency
personnel to isolate the source of compressed air from the air storage sub-system
950 such that the breathable air of the source of compressed air is directly deliverable
to the fill site 102 through the distribution structure 104. The air storage sub-system
950 may be housed in a fire rated enclosure that is certified to be rupture containable
to withstand elevated temperatures for a prescribed period of time. In some embodiment,
the air storage sub-system 950 may provide an additional supply of air to the building
structure in addition to the source of compressed air.
[0106] Figure 11 is a block diagram of the air distribution system 150 having the air storage sub-system
950, according to one embodiment. The air distribution system 150 may include a number
of supply units 100, a number of fill sites 102 that are coupled to the rest of the
air distribution system 150 through a distribution structure 104, according to one
embodiment. The air distribution system 150 may also include an air monitoring system
110 having a CO/Moisture sensor 106 and a pressure sensor 108, and the air storage
sub-system 950. Air storage tanks 1008 and/or a booster tank 1006 of the air storage
subsystem 950 of
Figure 10 may be supplied with breathable air through a source of compressed air that is coupled
to the air distribution system 150 through the supply unit 100 and supplied independently
of the supply unit 100. The air storage sub-system 950 may provide a spare source
of breathable air to the air distribution system 150 in addition to an external source
of compressed air.
[0107] In one embodiment, the distribution structure 104 that is compatible with use with
compressed air may facilitate dissemination of the breathable air of the source of
compressed air to multiple locations of the building structure.
[0108] Figure 12 is a process flow of a safety of a building structure having an air storage sub-system
(e.g., the air storage sub-system 950 of
Figure 10), according to one embodiment. In operation 1202, it may be ensured that a prescribed
pressure of an emergency support system (e.g., the air distribution system 150, 250,
350 of
Figures 1-3) maintains within a threshold range of the prescribed pressure by including a valve
(e.g., the valve of a series of valves 408 of
Figure 4B) of the emergency support system 150 to prevent leakage of breathable air from the
emergency support system 150. In operation 1204, a filling process of a breathable
air apparatus may be safeguarded by enclosing the breathable air apparatus in a secure
chamber (e.g., the holders 612 of
Figure 6A) of a fill site (e.g., the fill site 102 of
Figures 1-3) of the emergency support system 150 of the building structure to provide a safe
placement to supply the breathable air to the breathable air apparatus.
[0109] In operation 1206, a spare storage of breathable air may be provided through an air
storage tank (e.g., the air storage tanks 1008 of
Figure 10) of a storage sub-system (e.g., the air storage sub-system 950 of
Figure 10) to store the breathable air that is replenishable with a source of compressed air.
In operation 1208, corrosion and/or physical damage due to weather may be prevented
by incorporating a supply unit enclosure (e.g., the supply unit enclosure 500 of
Figure 5) that is weather resistant. In operation 1210, intrusion of the supply unit (e.g.,
a supply unit 100 of
Figures 1-3) potentially compromising the safety and reliability of the breathing emergency support
system 150 may be prevented by incorporating a locking mechanism (e.g., the locking
mechanism 502 of
Figure 5) of the supply unit enclosure 500.
[0110] In operation 1212, physical damage of various external hazards may be minimized to
protect the supply unit 100 and the fill site 102 from any of an intrusion and damage
through utilizing a robust metallic material to the supply unit enclosure 500. In
operation 1214, leakage of air from the emergency support system 150 leading to a
potential pressure loss of the emergency support system 150 may be prevented through
utilizing a valve 408 of any of the supply unit 100 and the fill site 102.
[0111] Figure 13 is a process flow that describes further the operations of
Figure 12, according to one embodiment. In operation 1302, transfer of breathable air from the
source of compressed air to the emergency support system 150 may be discontinued through
utilizing a valve 408 of the emergency support system 150. In operation 1304, breathable
air from the emergency support system 150 may be released automatically when the system
pressure of the emergency support system 150 exceeds the prescribed pressure through
triggering a safety relief valve 408 of any of the supply unit 100 and the fill site
102.
[0112] In operation 1306, compatibility of the emergency support system 150 and the source
of compressed air of an authority agency may be ensured through any of a CGA connector
(e.g., the connector 406 of
Figure 4A) and a RIC/UAC connector (e.g., the RIC/UAC connector 610 and 620 of
Figures 6A and
6B) of the supply unit 100. In operation 1308, a fill pressure may be adjusted to ensure
that the fill pressure of the source of compressed air does not exceed the prescribed
pressure of the emergency support system 150 through a pressure regulator of the supply
unit 100.
[0113] In operation 1310, the system pressure of the emergency support system 150 and/or
the fill pressure of the source of compressed air may be monitored through the pressure
gauge of the supply unit enclosure 500. In operation 1312, accessibility of the supply
unit enclosure 500 through providing luminescence in reduced light environments may
be improved by incorporating a visible marking. In operation 1314, a fill site 102
may be isolated from a remaining portion of the emergency support system 150 using
an isolation valve of the fill site 102 such that the remaining portion of the emergency
support system 150 is utilizable in an emergency situation.
[0114] Figure 14 is a process flow that describes further the operations of
Figure 13, according to one embodiment. In operation 1402, the isolation valve (e.g., a valve
of a series of valves 408 of
Figure 4) may be automatically actuated based on an air pressure sensor of the emergency support
system 150. In operation 1404, a fill pressure of the fill site 102 may be adjusted
to ensure that the fill pressure does not exceed the pressure rating of the breathable
air apparatus through a pressure regulator of the fill site 102.
[0115] In operation 1406, the fill pressure of the fill site 102 and/or the system pressure
of the emergency support system 150 may be monitored by incorporating a pressure gauge
to the fill site 102. In operation 1408, the distribution structure 104 may be enabled
to withstand elevated temperatures for a period of time using a fire rated material
(e.g., the fire rated material 702 of
Figure 7A) to encase the distribution structure 104.
[0116] In operation 1410, the fire rated material 702 may be prevented from damage by incorporating
a sleeve at least three times an outer diameter of each pipe of the distribution structure
104 exterior to the fire rated material 702. In operation 1412, physical damage to
the distribution structure 104 potentially compromising the safety and integrity of
the emergency support system 150 may be prevented by utilizing a robust solid casing
of the distribution structure 104. In operation 1414, the robust solid casing may
be protected from any damage using another sleeve at least three times an outer diameter
of a pipe of the distribution structure 104 exterior to the robust solid casing.
[0117] Figure 15 is a process flow that describes further the operations of
Figure 14, according to one embodiment. In operation 1502, impurities and/or contaminants in
the breathable air of the breathing emergency support system 150 may be automatically
tracked and recorded through an air monitoring system 110. In operation 1504, air
dissemination to the fill sites 102 may be suspended automatically in a case that
an impurity level and/or contaminant concentration exceeds a safety threshold. In
operation 1506, the system pressure of the emergency support system 150 may be tracked
and recorded through a pressure monitoring system.
[0118] In operation 1508, the pressure monitoring system and the fire alarm system of the
building structure may be electrically coupled such that the fire alarm system is
automatically triggered through a pressure switch when the system pressure of the
emergency support system 150 is outside a safety range. In operation 1510, a warning
signal may be electrically transmitted to an emergency supervising station through
the pressure switch when the system pressure of the emergency support system 150 is
below the prescribed level.
[0119] In operation 1512, an alarm may be automatically triggered and a signal may be coupled
electrically to any of relevant administrative personnel of the building structure
and the emergency supervising station when an intrusion of the supply unit 100 occurs
through a tamper switch of the locking mechanism 502 of the supply unit enclosure
500. In operation 1514, pressure of the breathable air stored in the air tank may
be increased through a pressure booster (e.g., the pressure booster 1004 of
Figure 10) to increase a pressure of the breathable air compared to the pressure of the breathable
air in air storage tanks (e.g., the air storage tanks 1008 of
Figure 10) to ensure that the emergency support system 150 constantly has a supply of breathable
air that has enough pressure to fill the breathable air apparatus.
[0120] Figure 16 is a process flow that describes further the operations of
Figure 15, according to one embodiment. In operation 1602, a supply of breathable air in the
air storage tank 1008 may be conserved through utilizing a driving air source (e.g.,
the driving air source 1002 of
Figure 10) to drive the pressure booster 1004.
[0121] Figure 17 is a process flow of a safety of a building structure having a fill station (e.g.,
the fill station 102A of
Figure 6A), according to one embodiment. In operation 1702, it may be ensured that a prescribed
pressure of an emergency support system (e.g., the air distribution system 150,250,
350 of
Figures 1-3) maintains within a threshold range of the prescribed pressure by including a valve
(e.g., the valve of a series of valves 408 of
Figure 4) of the emergency support system 150 to prevent leakage of breathable air from the
emergency support system 150. In operation 1704, a filling process of a breathable
air apparatus may be safeguarded by enclosing the breathable air apparatus in a secure
chamber (e.g., the holders 612 of
Figure 6A) of a fill site (e.g., the fill site 102 of
Figures 1-3 of the emergency support system 150 of the building structure to provide a safe placement
to supply the breathable air to the breathable air apparatus.
[0122] In operation 1706, the prescribed pressure of the emergency support system (e.g.,
the air distribution system 150, 250, 350 of
Figures 1-3) may be maintained such that a system pressure is compatible with the breathable
air apparatus through a distribution structure (e.g., the distribution structure 104
of
Figures 1-3) that is rated for use with compressed air that couples the supply unit 100 and the
fill site 102 to transfer breathable air of the source of compressed air to the fill
site 102.
[0123] Figure 18 is a process flow of a safety of a building structure having a fill site (e.g., the
fill site 102 of
Figures 1-3) according to one embodiment. In operation 1802, it may be ensured that a prescribed
pressure of an emergency support system (e.g., the air distribution system 150,250,350
of
Figures 1-3) maintains within a threshold range of the prescribed pressure by including a valve
(e.g., a valve of a series of valves 408 of
Figure 4) of the emergency support system 150 to prevent leakage of breathable air from the
emergency support system 150. In operation 1804, an air extraction process may be
expedited from the emergency support system 150 by including a RIC/UAC fitting (e.g.,
the RIC/UAC fitting 620 of
Figure 6B) to a fill panel 102B to fill a breathable air apparatus.
[0124] Figure 19 is a process flow of a safety of a mine structure, according to one embodiment. In
operation 1902, it may be ensured that a prescribed pressure of an emergency support
system (e.g., the air distribution system 150, 250 and 350 of
Figures 1-3) maintains within a threshold range of the prescribed pressure by including a valve
(e.g., a check valve of a series of valves 408 of
Figure 4) of the emergency support system 150 to prevent leakage of breathable air from the
emergency support system 150.
[0125] In operation 1904, a filling process of a breathable air apparatus may be safeguarded
by enclosing the breathable air apparatus in a secure chamber (e.g., the holders 612
of
Figure 6A) of a fill site 102 of the emergency support system 150 of the mine structure to
provide a safe placement to supply the breathable air to the breathable air apparatus.
In operation 1906, a spare storage of breathable air may be provided through an air
storage tank 1008 of storage sub-system 950 to store the breathable air that is replenishable
with a source of compressed air.
[0126] Although the present embodiments have been described with reference to specific example
embodiments, it will be evident that various modifications and changes may be made
to these embodiments without departing from the broader spirit and scope of the various
embodiments. For example, the various devices, modules, analyzers, generators, etc.
described herein may be enabled and operated using hardware circuitry (e.g., CMOS
based logic circuitry), firmware, software and/or any combination of hardware, firmware,
and/or software (e.g., embodied in a machine readable medium). For example, the various
electrical structure and methods may be embodied using transistors, logic gates, and
electrical circuits (e.g., Application Specific Integrated Circuitry (ASIC)).
[0127] In addition, it will be appreciated that the various operations, processes, and methods
disclosed herein may be embodied in a machine-readable medium and/or a machine accessible
medium compatible with a data processing system (e.g:, a computer system), and may
be performed in any order. Accordingly, the specification and drawings are to be regarded
in an illustrative rather than a restrictive sense.
[0128] The above disclosed invention may be made in different manufacturing environments
and/or may be used in different industrial applications. For example, the different
components such as pressure gauges, air storage tanks, hose pipe, breathable air apparatus,
CGA connector, RIC/UAC connector, respiratory mask, valves which constitute a breathable
air safety system may be manufactured in one or more manufacturing environments and/or
may be assembled at a location to build the breathable air safety system having an
air storage sub-system. As far the usage, the breathable air safety system may be
used, for example, in multiple types of structures to facilitate efficient delivery
of breathable air in case of an emergency situation. Such structures include, but
are not limited to, buildings, mines, tunnels, etc. Whereas many alterations and modifications
of the embodiments will no doubt become apparent to a person of ordinary skill in
the art after having read the foregoing description, it is to be understood that the
particular embodiments shown and described by way of illustration are in no way intended
to be considered limiting. By way of example, although efficiently providing breathable
air in case of emergency situation through the breathable air safety system is one
particularly useful application, it is to be appreciated that the scope of the present
teachings is not limited to providing breathable air to the emergency personnel, but
rather can include storing the breathable air in an air storage sub-system, maintaining
a prescribed pressure in the emergency support system, tracking impurities arid contaminants
in the breathable air, safeguarding a filling process before dispersing the breathable
air at multiple locations of the structure.
[0129] Those skilled in the art may understand that the breathable air safety system may
be used in conjunction with one or more systems, that may depend upon particular architectural
style of the structure in a manner that provides efficient access to the breathable
air of the air distribution system reliably and is not limited to the vertical and
horizontal position of the structure as mentioned in above embodiments. Thus, references
to the details of the described embodiments are not intended to limit their scope.
