Failure to follow these warnings can result in serious
personal injury or death.
Particles and contaminants can enter a supplied-air
respirator system when air supply hoses are discon-
nected and/or reconnected in a contaminated atmos-
phere. This could result in serious injury or death
depending on the toxicity of the contaminant involved.
It is the responsibility of the user to determine the
potential risk and to take the necessary precautions
which may include a requirement that NO disconnec-
tion or reconnection of air-supply hoses be permitted
in a contaminated atmosphere. If in doubt DO NOT

DESCRIPTION
OPERATING PRINCIPLES
The PremAire Cadet Escape Respirator is a combination
supplied-air respirator with self-contained breathing appa-
ratus (SCBA) for escape.
The PremAire Cadet Escape Respirator utilizes a pres-
sure-demand regulator mounted at the facepiece. This
mask mounted regulator (MMR) maintains a slight positive
pressure within the facepiece while regulating and reduc-
ing the air supply to a breathable pressure. This is accom-
plished by using a diaphragm that senses the breathing
demands of the user in a controlled feedback state. The
positive pressure of air inside the facepiece, whether the
wearer is inhaling or exhaling, is to prevent contaminants
from entering the facepiece, should there be slight face-
to-facepiece seal leakage.
The respirator is suitable for use with a large, compressed
air cylinder of breathable air or a bank of cylinders set up
in cascade fashion. Alternatively, the PremAire Cadet
Escape Respirator can be used with a compressor system
designed and configured to supply respirable breathing air
to the respirator, within the NIOSH approved pressure
range.
In normal use, the PremAire Cadet Escape Respirator is
connected to an air supply of a type and duration select-
ed by the user and will provide respiratory protection as
long as the user remains connected to the air supply. The
respirator allows the wearer to work within the limits of the
approved air-supply hose. The escape cylinder is not to
be used for entry. The escape cylinder should not be used
to switch from one airline to another. However, should the
primary air supply fail or be interrupted, the emergency-
escape cylinder enables the wearer to egress from the
potentially IDLH atmosphere.
CYLINDER AND VALVE ASSEMBLY
The cylinder and valve assembly consists of a cylinder
and a combination cylinder valve and first stage regulator
valve. The cylinders are available in 5, 10, and 15 minute
rated service time durations. The cylinders are available in
aluminum or carbon fiber material options.
The valve assembly includes a handwheel to open and
close the cylinder air supply, a recessed/protected pres-
sure gauge to measure cylinder contents, a cylinder fill
port with check valve to pressurize the cylinder, a high
pressure relief device to protect the cylinder from over-
pressurization, an intermediate pressure relief valve to
protect the second stage regulator from over-pressuriza-
tion, and a first stage regulator valve to reduce cylinder
pressure to a suitable intermediate pressure. The first
stage regulator valve incorporates a downstream design
and dual springs to provide maximum reliability.
ATTACHMENT HOSE
The attachment hose is used to connect the air supply
hoses to the cylinder and valve assembly. The attachment
hose includes a large sintered filter to remove particulate
from the supplied air source. The attachment hose
includes a check valve to prevent loss of air through the
hose when the cylinder valve is open (SCBA mode). MSA
approved quick-disconnects are fitted to the end of the
attachment hose.
SECOND STAGE REGULATOR
The second stage regulator is a pressure-demand regula-
tor. The release button on top of the regulator stops air
flow. To stop airflow, push the button in. To restart the
regulator, inhale sharply. The regulator attaches to the
facepiece with either Push-To-Connect or Slide-To-
Connect connectors.
FACEPIECE
The facepiece is available in two types; the Ultra Elite®
Facepiece and Advantage®4000 Facepiece. Each face-
piece type is available in three sizes. Each facepiece type is
available with a rubber head harness or net head harness.
The Ultra Elite and Advantage 4000 Facepieces include a
low-resistance, pressure-demand exhalation valve
designed for easy cleaning. An inhalation check valve in
the inlet housing keeps moisture and contaminants out of
the mask mounted regulator.
The Ultra Elite Facepiece is available with either push-to-
connect or slide-to-connect regulator inlet connections.
The Advantage 4000 Facepiece is only available with a
push-to-connect regulator inlet connection.
The Ultra Elite Facepiece has a speaking diaphragm for
clear, short-range communication.
CARRIER AND HARNESS ASSEMBLY
The carrier and harness assembly consists of a cylinder
carrier, a waist belt, a shoulder strap, and attachment
hose strain relief strap.
The carrier and harness assembly is available in nylon or
Kevlar materials.

TAL 903 (L) Rev. 1 - 10063148

DESCRIPTION
The cylinder carrier is available in standard and bag ver-
sions. The standard version includes metal clamps and
fabric straps. The bag version includes a single bag with
draw string. Cylinder carriers are removable from the har-
ness using quick release hardware.
The waist belt is available in two sizes, standard and
large. The waist belt includes a side-release buckle with
single adjustment. The shoulder strap includes a large
adjustment buckle.
A shoulder pad accessory is available.
The harness assembly includes a stand-by mount to stow
the second stage regulator when the respirator is not in
use.

OPERATION
Thoroughly inspect this respirator on receipt and before
use. This respirator is to be used only by trained and
qualified personnel. Read and understand these instruc-
tions before attempting to use this equipment.
AIR SOURCE
The purity of the air supply is the responsibility of the user.
The respirator is approved only when the air supplied
meets the requirements of the Compressed Gas
Association Specification G-7.1 for quality verification
level (Grade) D air or equivalent specifications.
AIR SUPPLY HOSE
The PremAire Cadet Escape Respirator can be used with
a wide range of MSA air supply hoses with a minimum
length of 8 feet and a maximum length of 300 feet. The
minimum air supply pressure is 70 psig and the maximum
air supply pressure is 90 psig. A maximum of 12 sections
of straight or uncoiled air supply hose may be used in
making up the working length of hose. When using coiled
hose, a maximum of six sections may be used and each
section is considered to be 50 feet long. Hose sections
vary from 8 feet to 100 feet lengths. The air-line connec-
tion to the apparatus is to be made through approved
quick-disconnects only.
MSA air supply hoses have temperature limitations.
DO NOT use the PremAire Cadet Escape Respirator
whenever ambient or inlet-air temperatures exceed
the limits specified below for each hose material.
Failure to follow this warning can result in serious per-
sonal injury or death.
INLET PRESSURE GAUGE
To ensure accurate pressure readings, the inlet pressure
gauge must be located at the air source.
SUPPLY HOSE–TO–SUPPLY HOSE CONNECTIONS
Use MSA-approved couplings only for supply hose con-
nections.
Hoses must only be interconnected with either the
threaded connector (3/4-16 UNF) or locking quick-dis-
connect couplings listed below. DO NOT use non-

FACEPIECE FIT CHECK
Check the inhalation valve by inhaling. If sufficient flow
of air is not received, do not use facepiece. The face-
piece must be repaired or replaced. Failure to follow
this warning can result in serious personal injury or
death.
9TAL 903 (L) Rev. 1 - 10063148

OPERATION
1. Check for facepiece fit
by holding the palm of
one hand over the inlet
connection and inhal-
ing. Hold breath at
least 10 seconds. The
facepiece should col-
lapse and stay col-
lapsed against the
face.
If it does not, adjust the facepiece and test again.
If adjustment does not provide a proper seal, do
not use the facepiece.
2. Test the exhalation
valve, take a deep
breath and hold it.
Block the inlet connec-
tion with the palm of
one hand and exhale. If
the exhalation valve is
stuck, a heavy rush of
air may be felt around
the facepiece.
Note It may be necessary to exhale sharply to open the
valve. If this does not release the valve, do not use the
facepiece.
This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical
characteristics (see ANSI Z88.2). An improper face-to-
facepiece seal may allow contaminants to leak into
the facepiece, reducing or eliminating respiratory pro-
tection. Do not use this device if a proper face-to-
facepiece seal can not be achieved. The face-to-face-
piece seal must be tested before each use. Never
remove the facepiece except in a safe, non-hazardous
non-toxic atmosphere. Failure to follow this warning
can result in serious personal injury or death.
CONNECTING THE AIR SUPPLY HOSE TO THE
ATTACHMENT HOSE
1. Verify that the cylinder valve knob is completely
closed (clockwise).
• DO NOT open the cylinder valve knob unless in an
emergency escape application. Doing so while
connected to an air source could result in depleted
cylinder pressure and decreased escape time.
• DO NOT enter any area which requires an escape
greater than the service life of the cylinder.
Cylinder life varies with the work rate of the indi-
vidual and may be shorter with heavy work loads.
Failure to follow these warnings can result in serious
personal injury or death.
2. Push the Firehawk
Regulator release but-
tons to shut off the reg-
ulator.

3. To maintain approval, container must be fully
charged with respirable air meeting the require-
ments of the Compress Gas Association specifica-
tion G-7.1 for Quality Verification Level (Grade) D
air or equivalent specification.
4. DO NOT use unless the cylinder is filled to the full
pressure approved.
5. DO NOT alter, modify, or substitute any compo-
nents without approval of the manufacturer.
6. Inspect frequently. Maintain according to manufac-
turer’s instructions. Repair only by properly trained
personnel.
Failure to follow this warning can result in serious per-
sonal injury or death.
SAFETY PRECAUTIONS FOR MSA SELF-CONTAINED
BREATHING APPARATUS CYLINDERS
Breathing apparatus cylinders should be fully recharged
as soon as possible after use.
Cylinders should not be stored partially charged for two
reasons
1. If used partially charged, the duration of the apparatus
is reduced.
2. The pressure relief device is only designed to protect
a fully charged cylinder from the effects of a fire.
For maximum safety, the cylinders should be stored full or
at a pressure above ambient but less than 100 psig.
Prior to recharging, cylinders must be examined externally
for evidence of high heat exposure, corrosion, or other
evidence of significant damage.

REMOVING THE RESPIRATOR
Additional information of value when performing external
and internal inspections of cylinders may be found in the
latest editions of CGA Publication C-6.1 “Standards for
Visual Inspection of High Pressure Aluminum Compressed
Gas Cylinder”, and/or CGA Publication C-6.2 “Guidelines
for Visual Inspection and Requalification of Fiber
Reinforced High Pressure Cylinders” available from the
Compressed Gas Association, Inc., 1725 Jefferson Davis
Highway, Suite 1004, Arlington, VA 22202-4102.
If there is any doubt about the suitability of the cylinder
for recharge, it should be returned to a certified hydrostat-
ic test facility for expert examination and testing.
Always check to be sure the retest date is within the pre-
scribed period and that the cylinder is properly labeled to
indicate its gaseous service. New label are restricted
items which are not available except through certified
hydrostatic test facilities.
When replacing cylinder valves or after the retesting of
cylinders, make sure the proper cylinder valve, burst disc,
and o-ring are installed prior to cylinder recharging.
Establish the service pressure of the cylinder. All cylinders
that are not 3AA type shall be filled to the designated ser-
vice pressure only (as found on the DOT approval label or
stamping). For cylinders manufactured under a U.S. DOT
exemption (i.e., DOT-E-####), the exemption should be
consulted and is available from the Associate
Administrator for Hazardous Materials Safety, Research
and Special Programs Administration, U.S. Department of
Transportation, 400 7th Street, SW, Washington, D.C.
20590-0001.
Note When refilling a PremAire Cadet Escape Respirator
cylinder and valve assembly, do not open the cylinder
valve knob. The high pressure fill port is directly exposed
to cylinder pressure. The fill port is independent of the
cylinder valve knob position. The fill port includes a check
valve that prevents cylinder air from escaping through the
fill port when the filling attachment is removed.
Remove the dust cap from the cylinder and valve assem-
bly fill port. Appropriately connect the filling system to the
fill port and refill. Terminate the filling when the pressure
reaches the service pressure and allow the cylinder to
cool to room temperature. If necessary, top-off the cylin-
der such that the service pressure is attained with the
cylinder at a temperature of 70°F. Appropriately discon-
nect the filling system from the fill port. Apply a leak
detecting solution to the fill port check valve to determine
if there is leakage. Replace the fill port dust cap. If there is
no leakage, the cylinder and valve assembly is ready for
service.
STORAGE
Do not store the respirator or spare cylinder and valve
assemblies within or near an area where the respirator can
or might be exposed to any substances that will attack
any part of the respirator, causing the respirator NOT to
perform as designed and approved.

COLD WEATHER OPERATION
SUGGESTED PROCEDURES FOR COLD WEATHER
OPERATION
Moisture can cause problems in respirators if it freezes.
However, moisture can cause freezing problems even if
the surrounding air is above freezing. This is due to air
flowing from the cylinder through the regulator drops from
cylinder pressure to close to atmospheric pressure very
quickly. As it does so it expands, causing the air and the
regulator to become colder. Although the surrounding
temperature may be warmer than 32°F, the temperature
inside the regulator may be lower. Any water inside could
turn to ice and restrict airflow.
1. To keep moisture from entering the Firehawk
Regulator. Stow the regulator in the stand-by mount.
2. When the respirator is away from heat, water spray
can freeze on the regulator surface. Ice can build up
and freeze the buttons and bypass valve. Before
entering or re-entering a hazardous atmosphere, make
sure the buttons and bypass valve are ice-free and
operating properly. Periodically, check the bypass to
be sure it is ice-free.
3. NIOSH certification requires a nosecup at tempera-
tures below 32°F. The nosecup reduces lens fogging
and must be used whenever freezing conditions are
encountered.
4. During cleaning, be careful to keep water from enter-
ing the regulator.
5. Thoroughly dry the facepiece and mask mounted reg-
ulator after cleaning and disinfecting. Follow
Confidence Plus® Cleaning Solution Instructions.

TAL 903 (L) Rev. 1 - 10063148

CLEANING AND DISINFECTING
Depending on the cleaning policy adopted, either a desig-
nated person or the user should clean each device after
each use. ANSI standards suggest that users should be
trained in the cleaning procedure. Confidence Plus
Cleaning Solution (P/N 10009971) from MSA is recom-
mended. It cleans and disinfects in one operation. It
retains its germicidal efficiency in hard water to inhibit the
growth of bacteria. It will not deteriorate rubber, plastic,
glass, or metal parts. Refer to label for user instructions.
• DO NOT use any cleaning substances that can or
might attack any part of the apparatus.
• Alcohol should not be used as a germicide
because it may deteriorate rubber parts.
• If not rinsed thoroughly, cleaning agent residue
may irritate the wearer’s skin.
1. Preparing Solution
a. Follow the instructions with the Confidence Plus
Cleaning Solution.
b. If the Confidence Plus Cleaning Solution is not
used, wash in a mild cleaning solution, rinse thor-
oughly, and submerge in a germicide solution for
the manufacturer’s recommended time.
2. Clean and Disinfect the Facepiece
a. Remove the mask mounted regulator from the face-
piece.
b. Thoroughly wash the facepiece (and nosecup) in the
cleaning solution. A soft brush or sponge can be
used to clean the soiled facepiece.
c. Rinse the facepiece and components in clean,
warm (110°F), water (preferably running and
drained).
d. Clean the pressure demand exhalation valve by
pressing in on the stem with a blunt object and
flushing with clean water.
e. Allow the facepiece to air dry. Do not dry the parts
by placing them near a heater or in direct sunlight.
The rubber will deteriorate.
f. Operate the exhalation valve by hand to be sure it
works properly.
Note Do not force-dry the parts by placing them in a
heater or in direct sunlight. The rubber will deteriorate.
When the facepiece is thoroughly dry, store the facepiece
in the plastic bag that it was shipped in.
3. In general, only the facepiece requires cleaning and
disinfecting after each use. If the apparatus is soiled
use a sponge damp with mild soap solution or use a
soft/medium bristle brush to remove deposits that
may interfere with normal operation of
a. Carrier and harness assembly
b. Cylinder and valve assembly
c. Firehawk Second Stage Regulator (Cover outlet of
the regulator to prevent water, dirt or debris from
entering)
4. Inspect the entire apparatus during reassembly. Follow
the inspection instructions.
5. Thoroughly dry the facepiece and regulator after
cleaning and disinfecting. The facepiece can trap
water that could enter the regulator.

VISUAL INSPECTION AND FUNCTIONAL CHECKS
18
TAL 903 (L) Rev. 1 - 10063148
INSPECTION
Inspect the entire respirator after it is cleaned and disin-
fected. ANSI Standards Z88.2 and Z88.5, describe three
levels of inspection procedures which are to be per-
formed. Refer to these documents, or to an inspection
program prepared by a health professional in establishing
an inspection program. Detailed repair procedures are
located in MSA User’s Maintenance Instructions.
• If the respirator does not meet any of the following
inspections, it must be removed from service.
• DO NOT inspect the air mask before cleaning if
there is danger of contacting hazardous contami-
nants. Clean and disinfect first, then inspect.
• DO NOT use any cleaning substances that can or
might attack any part of the apparatus.
Failure to follow this warning can cause inhalation or
skin absorption of the contaminant and result in seri-
ous personal injury or death.
COMPONENT INSPECTION (AFTER EACH USE AND
MONTHLY)
1. Facepiece
a. Inspect the facepiece for rubber deterioration, dirt,
cracks, tears, holes, or tackiness.
b. Check the head harness straps for breaks, loss of
elasticity, missing buckles or straps. Check the
straps for signs of wear.
c. Inspect the lens for cracks, scratches, and a tight
seal with the facepiece rubber.
d. The exhalation valve must be clean and operate
easily. The valve must move off the seat and return
when released.
e. Inspect the facepiece adapter for damage. Also
check to be sure the inhalation check valve is pre-
sent.
2. Cylinder and Valve Assembly
Breathing apparatus cylinders should be recharged as
soon as possible after use. Cylinders should not be
stored partially charged for two reasons
• If used without recharge, the service life of the res-
pirator is reduced.
• The cylinder burst disc vents excess pressure if a
full cylinder is over exposed to fire or heat. If the
cylinder is not full, it may be damaged before the
burst disc vents.
a. If the cylinder is less than FULL, recharge it before
storing it. Cylinder air must be at least CGA Quality
Verification Level (Grade) D respirable air.
b. Inspect the cylinder valve for signs of damage.
c. Inspect the cylinder body for cracks, dents, weak-
ened areas, corrosive agent, causing the fibers to
break or peel, or signs of heat-related damage. If
the cylinder is damaged return it to an MSA Service
Center. Call 1-800-MSA-2222 for instructions.
d. Check the hydrostatic test date on the cylinder
approval sticker located on the cylinder neck.
Aluminum and carbon fiber cylinder must be tested
every five years.
e. Be sure that the gauge needle and face are clearly
visible through the lens.
f. Inspect the high pressure relief device. Verify that
the relief holes are clear and free of debris or other
contamination.
g. Inspect the intermediate pressure relief valve. Verify
that the relief holes are clear and free of debris or
other contamination.
h. Inspect the valve assembly seal ring to verify that it
is present and properly seated. Inspect the seal ring
for rubber deterioration, dirt, cracks, tears, holes, or
tackiness.
i. Inspect the hose connections. Verify that the hoses
are properly secured.
j. Inspect the fill port. Verify that the fill port dust cap
is present and properly secured.
It is also essential that the required inspections and tests
be performed on all SCBA cylinders in accordance with
Department of Transportation (DOT) regulations. DOT reg-
ulations require that composite cylinders be retired from
service after the fifteenth year. Please note this does not
include cylinder valve assembly which may be reused.
Aluminum cylinder service life is indefinite if proper
inspection and hydrotest procedures are followed and
they indicate that the cylinder may remain in service.
Contact an MSA distributor or sales associate for addi-
tional information regarding this policy.
Note ANSI Z88.5 recommends checking cylinder pres-
sure weekly. For maximum safety the cylinders should be
stored full or empty (pressure above ambient but less than
100 psig).
3. Carrier and Harness
a. Inspect all harness components for cuts, tears,
abrasion or signs of heat or chemically-related dam-
age.
b. Inspect the cylinder carrier components for cuts,
tears, abrasion or signs of heat or chemically-relat-
ed damage. Verify that the carrier securely retains
the cylinder.
4. Record Keeping
Following inspection, the date and initials of the desig-
nated person should be recorded on an inspection
tag. A more detailed record of the operations per-
formed can be noted on an inspection and mainte-
nance log. Inspection tags and inspection and mainte-
nance logs are available from MSA. When the inspec-
tion data has been recorded, the breathing apparatus
is stored in a ready position.

VISUAL INSPECTION AND FUNCTIONAL CHECKS
FUNCTIONAL CHECKS (AFTER EACH USE AND
MONTHLY)
1. Check that the regulator and facepiece can hold a
negative pressure.
a. Verify that the cylinder valve is closed.
b. Hold the facepiece against the face to create an
effective seal.
c. Attach the regulator to the facepiece and inhale
until the facepiece begins to collapse against the
face. Hold breath for about 10 seconds. The nega-
tive pressure should be maintained and the face-
piece should remain collapsed against the face for
the entire 10 seconds.
d. Do not use the apparatus if negative pressure can-
not be maintained in the facepiece. Return the regu-
lator and facepiece to a certified repairperson.
2. Check second stage regulator operation.
a. Push the regulator release buttons.
b. Verify that the regulator bypass knob is fully closed
(clockwise).
c. Slowly open the cylinder valve to pressurize the res-
pirator. Verify that the cylinder valve is completely
opened.
d. Check the pressure gauge to verify that the cylinder
is full. Regulator functional checks must be con-
ducted with a full cylinder.
e. Open the regulator bypass knob (counter-clock-
wise). Verify that air flows from the regulator. Close
the bypass knob (clockwise).
f. Attach the regulator to the facepiece. Verify proper
regulator attachment by pulling on the regulator.
g. Hold the facepiece against the face to create an
effective seal.
h. Inhale sharply to start air flow. Breathe normally.
Verify proper regulator response. The regulator
should not make any unusual sounds including
whistling, chattering, or popping.
i. Remove the facepiece from the face. Verify that air
flows freely. Push the regulator release buttons.
Verify that air flow stops.
j. If the regulator fails to meet any of the above
checks, remove the apparatus from service. Return
the regulator to a certified repairperson.
3. Check the attachment hose quick-disconnect plug.
A.Verify that no air flows through the plug when the
cylinder valve knob is open.
4. After completing the functional checks, recharge the
cylinder and valve assembly before storing it.
