1. DESCRIPTION AND OPERATION
A. General Description of Equipment
(1) Purpose of the Equipment
The Essex Crewmember PBE (Ref. Figure 1) 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 (LiOH)
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
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 (primary indicator is the inflation of the hood shell), reassuring the
wearer that the equipment is functioning, and signaling when the equipment’s service
life is ended. (Ref. Figure 1).
(5) Packaging and Stowage Containers
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 (made
either from molded plastic, metal, or from Flame-Resistant fabric, depending on
model). 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, by the European Aviation Safety Agency
(EASA) to ETSO-C116 and ETSO-C99; by the Civil Aviation Authority of China
(CAAC); and by 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, units in hard
case stowage containers have tamper-evident seals.
For closed stowage brackets (MR-10046NS, and MR-10046NY), the tamper-evident
seals are the red-knotted plastic rope (Type A) or the tamper-evident labels (Type C).
(Ref. Figure 2)

D/B/A Essex PB&R Corporation
User Reference and Procedures Manual for the Essex Crewmember PBE
Document No: PRM-01, Revision: 21 Dated: 08/28/2015
9
For open-ended stowage brackets (MR-10042N) the tamper-evident seals are the
green plastic padlocks (Type B) and for (MR-10042NWA) the tamper-evident seals
are the green-knotted cable ties (Type D). (Ref. Figure 2)
For bracket-mounted, flange-mounted, or internal-mounted stowage cases ((MR-
10022N, 22NC, 22NEMB, 34N, 36N, 36NC, 37N, 39N, 49N, 49NA, and 50N), the
tamper-evident seals are the tamper-evident labels (Type C) and for (MR-10022NAA)
the tamper-evident seals are the green-pull grip seals (Type E). (Ref. Figure 2)
There are no seals for units stowed in Flame-Resistant fabric containers (MR-10035N,
MR-10051N, and MR-10052N).
(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)). A force of
approximately 18-28 pounds will be required to remove the pouch, or to lift the lid &
break the tamper-evident seals.
(3) Breathing System
Once the pouch is removed from its container and opened, oxygen flow is initiated by
snapping the two cylinders apart, which in turn activates the flashing green light on the
Service/End-of-Service Indicator. For the MR-10022NAA Unit, oxygen flow is
initiated by grasping one cylinder and sharply pulling the red ball. 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 in 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, minimizing
the gap between the mouth and device.

C. Operating Steps
(1) General Sequence of Steps
The operating steps for an Essex Crewmember PBE are generally the same for all
models, but access to the pouch will vary somewhat depending on type of stowage
container installed on the aircraft.
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.
The minor differences in accessing the pouch from its stowage container are noted
below.
(2) Accessing the Essex Crewmember PBE Equipment Pouch
