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
Document No: PRM-01, Revision: 21 Dated: 08/28/2015
Page 9
9
D/B/A Essex PB&R Corporation
User Reference and Procedures Manual for the Essex Crewmember PBE
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 ((MR10022N, 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.

D/B/A Essex PB&R Corporation
User Reference and Procedures Manual for the Essex Crewmember PBE
(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

(4) Activate the Oxygen Supply for all Model Numbers except MR-10022NAA (Ref.
Figure 23 below).
(a) Before activating the oxygen supply, be sure to position the front of the hood
correctly. There are two ways to be sure of this.
(i) If visibility permits, locate the amber-colored, transparent, non-metalized area
of the hood. This is the front of the hood. It should not be visible during the
activation and donning. The user should see only the metalized area.
(ii) While grasping the oxygen cylinders (one in each hand), make sure that the
oxygen valves are pointing away from the user’s body. (The oxygen valves are
thinner than the cylinders and will be covered with felt.)

(b) Unfold the hood far enough to reveal the oxygen cylinders. Grasp each securely,
one in each hand, make sure that the oxygen valves are pointing away from the
user’s body. (The oxygen valves are thinner than the cylinders and will be covered
with felt.)
(c) Sharply snap the oxygen cylinders away from each other. This sharp action pulls
on the two cords that trigger the oxygen flow and activates the green light on the
Service/End-of-Service Indicator.
NOTE: DO NOT PULL THE OXYGEN CYLINDERS APART SLOWLY.
DOING SO WILL INCREASE THE FORCE NECESSARY TO
ACTIVATE THE EQUIPMENT.
WARNING: TO AVOID LOSING OXYGEN ONCE THE SYSTEM IS
ACTIVATED, AND TO MINIMIZE THE AMOUNT OF
TOXINS THAT MAY ENTER THE HOOD, DON THE HOOD
PROMPTLY AFTER ACTIVATION.
(4a) Activate the Oxygen Supply for MR-10022NAA only (Ref. Figures 24 & 25 below).
(a) Before activating the oxygen supply, be sure to position the front of the hood
correctly. If visibility permits, locate the amber-colored, transparent, non-metalized
area of the hood. This is the front of the hood. It should not be visible during the
activation and donning. The user should see only the metalized area.
Unfold the hood far enough to reveal the oxygen cylinders. Grasp either cylinder
securely with one hand, and grasp the red ball with the other hand (Ref. Figure 24
below). Pull the red ball sharply, the cords and levers should separate completely
from the PBE (Ref. Figure 25 below). This sharp action triggers the oxygen flow
and activates the green light on the Service/End-of-Service Indicator. Discard the
red ball and its components.
WARNING: TO AVOID LOSING OXYGEN ONCE THE SYSTEM IS
ACTIVATED, AND TO MINIMIZE THE AMOUNT OF TOXINS THAT
MAY ENTER THE HOOD, DON THE HOOD PROMPTLY AFTER
ACTIVATION.

WARNING: AFTER DONNING THE HOOD, DO NOT OPEN THE
NECK SEAL EXCEPT TO QUICKLY TUCK IN HAIR,
OR TO ADJUST THE HOOD’S POSITION. HAVE
ANOTHER PERSON HELP IF NEEDED.
(d) The equipment is donned correctly if the oxygen cylinders are positioned over the
shoulders under each ear and the transparent amber-colored area is facing front.
If the hood is accidentally donned backwards, do not remove it. Instead, rotate
the hood until it is properly positioned.
WARNING: IF EITHER OF THE FOLLOWING CONDITIONS EXIST,
REMOVE THE EQUIPMENT AND DISCARD IT
IMMEDIATELY:
WARNING: DO NOT PASS ALONG AN ACTIVATED HOOD TO
ANOTHER PERSON ONCE IT IS DONNED. THIS WILL
CAUSE OXYGEN TO ESCAPE AND CAN
SUBSTANTIALLY REDUCE PERFORMANCE.
(6) Wearing the Hood
Full hood inflation takes from 2 to 3 minutes but the equipment is ready for use
immediately. During the first few minutes the oxygen makes a noticeably loud,
hissing sound that gradually diminishes. The oxygen stops flowing after 8 to 10
minutes, but enough oxygen remains in the hood for a full 15 minutes of usage.
WARNING: IF THE HOOD COLLAPSES AROUND THE FACE AT
ANYTIME, REMOVE IT IMMEDIATELY AND OBTAIN
A NEW ONE.
WARNING: DO NOT APPROACH ANY CLOSER TO A FIRE OR FLAMES
THAN THE NORMAL RANGE OF AN APPROVED FIRE
EXTINGUISHER, SINCE THE USER WILL ORDINARILY NOT
BE WEARING FIRE-RESISTANT CLOTHING.

(b) Note that warming and condensation inside the hood may occur. If this
interferes with vision, press the hood against the face to wipe away
condensation.
(c) Some users may experience mild ear popping as the air pressure inside the
hood gradually increases due to the oxygen flow.
(d) Interphone, megaphone and microphone communication are possible while
the hood is still inflating and during its operation. Press the phone device
directly against the hood for best operation. Or, place the phone device up
against the Adam’s apple.
WARNING: DO NOT REMOVE THE HOOD WHILE NEAR SPARKS OR
OPEN FLAME. SOME RESIDUAL OXYGEN MAY REMAIN
IN BOTH THE HOOD AND HAIR.
(7) Remove and Discard the Hood
Remove the PBE if the hood collapses over the face, or as soon as the red light in the
End-of-Service indicator comes on, or immediately after the emergency is under
control, whichever comes first.
(a) Leave the area of the emergency before attempting to remove the hood.
(b) To remove the hood, insert both hands under the neck seal, beneath the chin. Lift
the hood up and out to clear the face.
NOTE: EYEGLASS WEARERS SHOULD FIRST INSERT BOTH HANDS
UNDER THE NECK SEAL, THEN PULL THE HOOD FORWARD
AND OUTWARD, LIFTING IT UP OVER THE HEAD TO AVOID
DISLODGING THE EYEGLASSES.

across.
(c) If the oxygen system has not yet been activated, do so before disposing
of the equipment.
(i) Handle the oxygen disposal in an area where there is no potential danger
from sparks or other fire hazards.
(ii) After equipment has been activated, leave it alone for at least one hour, so
that all residual oxygen will dissipate.
(d) Dispose of the hood in compliance with federal, state and local EPA
regulations. Contact the appropriate agency for proper disposal procedures.
The white scrubber panels contain about 200 grams of lithium hydroxide
and/or lithium carbonate.
2. INSPECTION AND FAULT ISOLATION
A. General
(1) Inspection and inspection frequency of PBE’s in stowage containers should be in
accordance with your governing regulatory authority and your airline operating
procedure. The stowage containers will be inspected by one or more of the following
indicators: replace by date label, tamper-evident seals, and humidity indicators.
Please follow the inspection method that corresponds with your aircraft’s PBE
stowage container.
(2) For all models, the first step is to inspect the date on the replace by date label. If the
replace by date has not been exceeded proceed to the next inspection step. If the
replace by date has been exceeded, the unit must be immediately replaced.
B. Methods of Inspection after verification that the unit has not exceeded the replace by
date. Refer to Figures 28 and 29, respectively, for Essex’s recommended inspection
procedures.
(1) Tamper-Evident Seals: Tamper-evident seals are the primary and most
recommended means of determining serviceability for PBE’s. There are currently
five different types of tamper-evident seals used on PBE’s, depending on which type
of stowage container that the PBE’s are placed in. See Figure 2 of this manual for
Document No: PRM-01, Revision: 21 Dated: 08/28/2015
Page 43
43
D/B/A Essex PB&R Corporation
User Reference and Procedures Manual for the Essex Crewmember PBE
an illustration of the different types of tamper-evident seals.
(2) Humidity Indicator: Humidity indicators represent a second level of PBE
inspection, if so required. The purpose of the humidity indicator is to show that
moisture has gotten inside of the barrier pouch, and may come in contact with the
lithium hydroxide scrubbers inside of the hood. Please see Figure 27 below that
illustrates accept/reject criteria if you are required to use this method of inspection.
Blue Indicator: ACCEPT Pink Indicator: REJECT
Humidity Indicator Accept vs. Reject Criteria

3. REPAIR
A. General
(1) The Essex Crewmember PBE is not an owner repairable system. (Ref. para. 2.D.
for the statement of warranty, and 2.E. for return procedures).
(2) Minor maintenance repairs can be accomplished by the owner on stowage containers
to refit broken, torn or missing tamper-evident seals, or to realign serviceable
equipment within their stowage containers.
B. Refitting Broken, Torn or Missing Tamper-Evident Seals
(1) Five different, incompatible types of tamper-evident seals or labels have been used
on the Essex Crewmember PBE, depending on the date of manufacture and type of
stowage container (Ref. Figure 2). Also, refer to Figure 2 for the tamper-evident
seal part numbers to be used for ordering seals from Essex that need replacement.
(2) Equipment pouches stowed in metal containers that are open at the top (MR-10042N)
(Ref. Figure 13) have two, “Type B" green plastic pad-lock tamper-evident seals at
the top of the stowage container, one on each side of the container. To replace broken
or missing “Type B” tamper-evident seals (green plastic padlock) follow these steps:
(a) First verify the serviceability of the equipment pouch (Ref. Section 2.B.). Then
place the new tamper-evident seal inside of the container/pouch assembly with
the notched arm facing up.
(b) Thread the notched arm through the large hole in the side of the container.
(c) Continue to thread the notched arm over the container and through the hole in the
equipment pouch, from back to front.

5. THE ESSEX CREWMEMBER PBE TRAINING UNIT
A. Introduction
(1) The Essex Crewmember PBE training unit (MR-10021N, and MR-10021NAA) are
designed to help teach how to activate, don and doff the equipment correctly.
(2) This section reviews the differences between an Essex Crewmember PBE training
unit and a live unit, how to practice putting on and taking off the training hood, and
how to properly care for the training unit. When practicing with the Essex
Crewmember PBE Trainer, it is recommended that the special, disposable, sanitary
hood liner be used for good personal hygiene (Ref. para. 5.C. (1) below).
(3) Essex has performed Endurance Cycle Testing and have determined that the PBE
Trainers, if cycled properly as recommended by Essex in this manual, will last a
minimum of 200 cycles (excluding damage to the replaceable Neck Seal). Essex
recommends that a Usage Log be kept for each PBE Training Unit (reference Figure
33).
B. Operating Features
There are several major differences between the training unit and a live unit.
(1) The training unit is reusable.
(2) A sanitary plastic liner protects the user from unsanitary conditions while wearing the
training hood, allowing full visibility, and protecting the hood from possible damage.
WARNING: DISCARD THE SANITARY LINER AFTER EACH USE.
(3) The training unit has two empty, non-functioning oxygen cylinders. The training unit
is designed to mimic a live unit. Because there is no oxygen in the training unit, the
hood has breathing holes.
(4) There are no Carbon Dioxide Scrubbers and no Service/End-of-Service Indicator in
the training unit.
C. Operating Steps
(1) Plastic Training Liner (Optional)
Sanitary plastic liners, P/N CP3205, can be ordered from Essex PB&R.
Adjust the plastic liner so that its top paper edge is horizontal at the tip of the nose,

User Reference and Procedures Manual for the Essex Crewmember PBE
and the crease is centered vertically in the middle of the face.
Fold the liner’s rear pleat over, then secure it with ordinary cellophane-type tape
(Ref. Figure 32A).
(2) General Sequence of Steps
To open the training unit hood, follow the same sequence as for a live unit but with
the differences described in steps (a) through (d) below.
(a) Remove the unit from its storage pouch.
(b) For MR-10021N, separate the two empty oxygen bottles with the same motions
that would be used for a live unit (Ref. paragraph 1.C.(4)). For MR10021NAA, activate the simulated Oxygen assemblies with the same motion that
would be used for a live unit (Ref. paragraph 1.C.(4a)). This simulates
activating the oxygen system for the hood. The training unit uses spring clips to
mimic the resistance of a live unit’s valves.
WARNING: WHEN USING THE OPTIONAL TRAINING LINER, HOLD
THE HOOD DIRECTLY OVERHEAD WHEN DONNING IT.
DISTURBING THE LINER CAN INTERFERE WITH
VISION OR IMPAIR BREATHING (Ref. Fig. 32B).
(c) Open the neck seal of the unit, by inserting both hands into opening of neck seal,
with palms facing each other. (Ref. para. 1.C. (5)). Spread the neck seal apart
with back of hands, as with a live unit. Next, unlike a live unit, hold the training
unit directly overhead and lower it straight down over the plastic hood liner.
Remove hands from neck seal opening. Have a qualified observer check the
hood and liner for proper placement.
(d) Remove the hood by inserting hands, with palms facing front of neck, up and
into the neck seal opening and pulling neck seal opening up and over head.
Discard the liner when the practice session is complete.
(e) Refold unit and insert back into storage pouch.
(3) Verbal communication with the training hood with an interphone, megaphone and
microphone are similar to the live hood. (Ref. para. 1.B.(7) & Ref. Figures 1A and
32C).
D. Replacing Torn or Damaged Neck Seals
Replacement neck seals, P/N CP2126, can be ordered from Essex PB&R.
