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 &

User Reference and Procedures Manual for the Essex Crewmember PBE
Document No: PRM-02, Revision: 9 Dated: 1/01/2012
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.

(4) Activate the Oxygen Supply.
(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 5a
below). Pull the red ball sharply, the cords and levers should separate completely
from the PBE (Ref. Figure 5b on page 14). 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.

(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:
(1) THE SOUND OF THE OXYGEN FLOW IS
INAUDIBLE IMMEDIATELY AFTER DONNING.
(2) THE HOOD DOES NOT INFLATE WITHIN 2 TO 3
MINUTES, OR COLLAPSES.
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 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.
(a) Observe the flashing green Service/End-of-Service Indicator light inside the hood,
located to the left and just below eye level. When the red light flashes with the
green light, or when the hood collapses, move immediately to a safe area and
remove the unit.

(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
Service/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.

2. INSPECTION AND FAULT ISOLATION
A. General
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 PBE will be inspected by the following indicators: replace by date label,
tamper-evident seals, and humidity indicator.
B. Methods of Inspection after verification that the unit has not exceeded the replace by
date (also refer to Figure 8 on page 20 for Essex Industries dba Essex PB&R
Corporation’s recommended inspection procedures).
(1) Replace by Date Label: 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.
(2) Tamper-Evident Seals: Tamper-evident seals are the second step for determining
serviceability of the PBE.
(3) Humidity Indicator: The humidity indicator represents the third step of inspection.
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 7 below that illustrates acceptance criteria.
Blue Indicator: Unit is Acceptable Pink Indicator: Remove Unit
from Service within one (1)
calendar day (42 hrs. max).
