MR-10022NAA Crewmember PBE with Concealed Mounting Holes and Clear Lid
Note: Part Number DP3113(A) is the Essex Crewmember PBE without a barrier pouch or any
type of stowage bracket. The Model Number, MR-10022NAA, designates the type of
bracket configuration that Part Number DP3113(A) is assembled into. The Model
Number, MR-10021NAA does not require a bracket configuration.
1. DESCRIPTION AND OPERATION
A. General Description of Equipment
(1) Purpose of the Equipment
The Essex Crewmember PBE (Ref. Figure 1 on page 6) is a self-contained,
portable, personal breathing device designed to safeguard the wearer from the
effects of smoke, carbon dioxide, harmful gases, and oxygen deficiency while
managing in-flight fire, smoke or fume emergencies.
The equipment improves the wearer’s visibility in smoke-filled compartments,
protects the head and face from melting or dripping plastics, and shields the head
against brief exposure to heat and flame.
The primary functional component in the Essex Crewmember PBE is a portable
hood that contains both a breathable oxygen supply, and lithium hydroxide
scrubber panels that absorb exhaled carbon dioxide.
The hood has a self-fitting neck opening that seals out contaminants, retains the
oxygen and keeps the hood inflated during use. The entire unit is hermetically
sealed at Essex PB&R Corp. to protect the LiOH scrubber panels from outside air.
(2) Hood Shell Construction
The Essex Crewmember PBE hood is fabricated from a durable, tear-resistant
combination of polyimide and PFA films. The hood’s inner surface has an anti-fog
coating to improve visibility.

(3) Oxygen System
The Essex Crewmember PBE has two oxygen cylinders. Together they hold a
minimum of 36 liters of Aviator Grade oxygen. These cylinders meet SAE
Standard AS 8010 for breathing-oxygen purity, and have rupture protection in case
of over pressurization.

(4) Service/End-of-Service Indicator
The Essex Crewmember PBE features a battery-powered green and red light
Service/End-of-Service Indicator. Mounted slightly below eye level on the left
inner side of the hood, this indicator functions as a secondary indicator for
monitoring oxygen activation, reassuring the wearer that the equipment is
functioning, and signaling when the equipment’s service life is ended. (Ref.
Figure 1 on page 6).
(5) Packaging and Stowage Container
The Essex Crewmember PBE alone weighs 3.2 lbs (1.45 kg). It is folded and
packaged in a moisture resistant pouch, and stowed in a protective container. A
packaged Crewmember PBE is normally installed within 3 ft (.9 m) of each
required on-board fire extinguisher. Each airline should receive regulatory
approval for installation locations.
(6) Compliance
The Essex Crewmember PBE complies with the requirements of FAA Action
Notice A8150.2 and is approved according to FAA TSO-C116 and TSO-C99. The
Essex Crewmember PBE is also approved: under BCAR B4-8, United Kingdom –
Civil Aviation Authority (CAA) requirements thereby we are also approved by the
European Aviation Safety Agency (EASA); by the Civil Aviation Authority of
China (CAAC), and the Brazilian Civil Aviation Authority (ANAC).
(7) Useful Service Life (Warranty Period)
The Essex Crewmember PBE has a 10-year 6-month, warranted, useful service life,
beginning from the date of manufacture.
B. Operating Features
(1) Tamper-Evident Seals
To ensure that the Essex Crewmember PBE has not been tampered with, each stowage
container has a tamper-evident seal, P/N 6851007-14. The tamper-evident seal for
Model # MR-10022NAA, is a green-knotted cable tie. (Ref. Figure 2 on page 10)
(2) Pouch Access
The sealed barrier pouch containing the Essex Crewmember PBE is easily accessed and
removed from its stowage container (Ref. para. 1.C. (2) on page 11). A force of
approximately 18-28 pounds will be required to remove the pouch, or to lift the lid &

8
break the tamper-evident seals.
(3) Breathing System
Once the pouch is removed from its container and opened, oxygen flow is initiated by
grasping one cylinder with one hand, and pulling the red ball with the other hand until it
is completely released from the PBE, which in turn activates the flashing green light on
the Service/End-of-Service Indicator. The red ball, pull cords, and release levers
should be discarded immediately upon activation. One bottle releases oxygen rapidly,
whereas the second bottle discharges oxygen slowly. An audible hissing sound and
inflation of the unit within (2) minutes indicates the PBE is operating properly.
Once donned, the Essex Crewmember PBE will protect the wearer for up to 15
minutes. Although both bottles will completely discharge in 8 to 10 minutes, enough
oxygen will remain for the full, specified 15 minutes of respiratory protection. When
the unit deflates to the point where it touches the wearer’s head and face, or when the
red light on the Service/End-of-Service Indicator flashes, the unit’s useful life has
ended and must be removed.
The Essex Crewmember PBE operates at a positive pressure. The neck seal acts as a
relief valve to prevent excessive pressure from building up inside the hood.
(4) Time Required to Put On and Take Off Hood
A trained user can access, and don the hood in approximately 15 seconds. It
can be removed in less than 5 seconds.
(5) Maneuverability During Use
The Essex Crewmember PBE does not restrict or interfere with normal body
movements. Even when fully inflated, it is compact enough that the wearer can pass
through openings as small as 18 x 18 in (460 mm x 460 mm).
(6) Carbon Dioxide Control
Special fabric panels inside the hood control carbon dioxide buildup. These panels
contain a dustless lithium hydroxide absorbent sealed inside a double walled membrane,
which keeps carbon dioxide concentrations at safe levels during the hood’s 15-minute
service period.
(7) Interpersonal Communications
Persons wearing the Essex Crewmember PBE can communicate by unaided voice with
other people wearing hoods, at a distance of at least 13.1 ft (4 m) away.

When using an interphone, megaphone or microphone, it may be necessary to pull the
skirt of the hood down so the scrubber is below mouth level. Press the phone unit
firmly against the hood film in front of the mouth as shown in Figure 1A below,
minimizing the gap between the mouth and device.

C. Operating Steps
(1) General Sequence of Steps
The normal operating sequence is: access the PBE, open the equipment pouch, activate
the system, don the hood, wear it as needed, then remove and dispose of it after use.
(2) Accessing the Essex Crewmember PBE Equipment Pouch
Grasp the strap attached to the lid and pull sharply to break the green-knotted cable tie.
Approximately 18 to 28 pounds of force will be required to lift the lid and break the
tamper-evident seal. Grasp the yellow nylon strap and pull the PBE from the bracket.
Note: The yellow nylon strap is located at the bottom of the pouch.
