breathing apparatus on all apparatus assigned to their station in addition to 

their assigned SCBA daily. 

All personnel shall inspect their assigned self-contained breathing apparatus 

daily. This responsibility shall not be delegated

POLICY 

As there is no way to predetermine all hazardous conditions, 

concentrations of toxic materials or percentages of oxygen in the air 

during emergency operations. Therefore self-contained breathing 

apparatus (SCBA) are required to be worn and used at all times by all 

personnel when: (NFPA 1404) 

* At the scene of emergency incidents where the atmosphere could be immediately 

dangerous to life and health (IDLH) or may become oxygen deficient. 

* At the scene of emergency incidents where the atmosphere could be contaminated by toxic 

vapors, gases, fumes, mist or dust caused by fire, explosions, leaks, spills, or other means. 

* Involved in fire fighting, ventilation, salvage and overhaul operations, or under conditions 

involving spills or releases of chemicals or other toxic materials. 

* Entering confined spaces that t are oxygen deficient; i or, where smoke, chemicals, toxic 

agents, toxic fumes of unknown type gases or vapors are present. 

* Required by the Incident Commander.

POLICY 

Daily: All personnel shall inspect their assigned SCBA and initial the appropriate 

Form 20. This responsibility shall not be delegated. Fire Fighter Specialist shall 

inspect all unassigned SCBA’s on all apparatus assigned to their station and initial the 

appropriate Form 20. 

Weekly: All personnel shall don their SCBA and insure they can maintain a negative 

pressure facepiece seal, test proper operation of the first breath on function, manual on 

button, bypass valve operation, exhalation valve operation, and shut-off button. When 

completed they shall date and print their last name on the appropriate Form 20. This 

responsibility shall not be delegated. d The Fire Fighter Specialist shall inspect all 

unassigned SCBA’s on all apparatus at their assigned station and complete all entries 

on the appropriate Form 20. 

After Each Use: All SCBA’s shall be cleaned, tested, and returned to a ready for use 

status. Each facepiece shall be cleaned and disinfected. 

Air Cylinders: shall be stored, filled, and maintained in a safe manner.

POLICY 

All personnel: shall demonstrate proficiency in don a SCBA within a 60-second time 

limit annually. 

All personnel: shall don a SCBA and conduct a search while in a simulated smoke-filled 

atmosphere annually. 

All personnel: shall properly connect the Emergency Breathing Safety System and 

review its uses and limitations Bi-annually. 

All personnel: shall have a quantitative facepiece fit test annually.

SAFETY ISSUE 

* Air Cylinders shall not be filled without the proper hydrostatic test identification markings. 

The hydrostatic test date shall be checked prior to filling each air cylinder. Any air cylinder 

found to be out of hydrostatic date (every 5 years) shall be immediately removed from 

service, tagged, and sent to Pacoima SCBA shop to be hydrostatic tested. 

* The use of self-contained breathing apparatus for water rescue incidents is -PROHIBITED 

* Should a fire fighter find themselves trapped underwater, maneuver to a horizontal face-up 

position. This orientation can trigger the SCBA to operate in a pressure demand mode 

extending the users available air supply. 

* The use of self-contained breathing apparatus does not offer complete protection in 

atmospheres containing gases or vapors that are absorbed through the skin, i.e., 

Hydrocyanic Acid (Hydrogen Cyanide) Methyl Bromide. Do not enter these 

atmospheres until thoroughly ventilated and approved by hazardous materials 

personnel.

* The Sperian Warrior Self-Contained Breathing 

Apparatus is the latest addition to the County of Los 

Angeles Fire Department’s SCBA inventory. The 

Warrior SCBA meets all requirements of the National 

Institute for Occupational Safety and Health (NIOSH) 

in accordance with the requirements of 42 CFR 84, 

and the National Fire Protection Administration 

(NFPA) 1981 Standard on Open Circuit Self 

Contained Breathing Apparatus for Emergency 

Services, 2007 Edition. 

* The most significant change in the 2007 edition is 

the mandatory requirement for all emergency 

services SCBA to also be NIOSH certified as a 

CBRN SCBA in accordance with the NIOSH 

Statement for Standard for NIOSH CBRN SCBA 

Testing. This requirement provides respiratory 

protection from CBRN terrorism agents (specified 

chemicals, biological agents, and radiological 

particulates) that could be released as a result of a 

terrorism attack. 

* Several new features including the Heads Up 

Display (HUD), Informational Lighting, Universal Air 

Connection (UAC), and Emergency Breathing Safety 

System (EBSS) provide an increased level of safety 

for the user.

BACKPACK HARNESS AND FRAME 

The backpack consists of a lightweight aluminum 

backplate with an aluminum hip-plate that both hinges 

and swivels on the backplate. The backplate has three 

integrated carrying handles with carabineer attachment 

points. Each attachment point is rated to 1,000 pounds. 

Th t i l t l b d h dj t t i t th t ll 

The stainless steel band has adjustment points that allow 

for the use of 30-minute, 45-minute or 60-minute air 

cylinders.


A reflective strip will be adhered the center section of the 

stainless steel band. A color coded system will allow for 

general identification of each SCBA assigned

Designed for a secure, stable fit, with weight 

concentrated at the hips, the straps are made Kevlar and 

incorporate a metal automotive-style waist buckle. The 

waist straps adjust from both sides by pulling on the 

yellow tabs keeping the SCBA centered during donning. 

A regulator belt clip is attached to the left side waist strap 

for storage of the second stage regulator. The regulator 

belt clip is designed to keep the second stage regulator 

clean and secure until it is attached to the facepiece. 

The shoulder straps adjust by pulling on the gray tabs 

and maintain there adjusted position using an alligator 

type clip.


The intermediate pressure hose is routed over the left 

shoulder and incorporates the electrical/pneumatic 

connector. 

This connection can only be made in the correct 

orientation completing the air supply to the second stage 

regulator and the electronics required for the Heads-Up 

Display. The quick connect fittings employ a push/pull 

release to prevent accidental disconnection. The male 

connection has to be pushed into the female fitting and 

the sleeve on the female fitting pulled back to allow 

separation.


Located on the lower right side of the backpack is the 

battery compartment that houses four C size batteries. 

All electronics are supplied by these batteries except the 

Voice Amplifier.


Amber LED’s on the PASS Device and the Backpack act 

as a battery status indicator. The amber LED’s will flash 

once every 10 seconds to indicate a usable battery 

condition. The amber LED’s will flash every 2 seconds to 

indicate a low battery condition.

AIR CYLINDER 

A 45-minute (66 cubic foot – 1800 liter) air cylinder will be the standard 

issue for the Warrior SCBA. The air cylinder is of composite construction 

with an aluminum liner overwrapped by a carbon fiber. The composite 

construction offers a significant weight savings compared to older hoopwrapped 

designs. Attention to the appropriate handling of composite 

air cylinders shall be maintained. Composite air cylinders will not 

withstand the abusive treatment that the aluminum hoop-wrapped air 

cylinders could. 

When placing an SCBA in service, FULLY OPEN the air cylinder valve. 

Partial opening can cause the loss of breathing air as cylinder pressure 

decreases. The air cylinder valve does not incorporate a locking 

sleeve. The valve knob is designed not to close under normal 

operations. 

All air cylinders intended for use with the Warrior SCBA’s have a maximum 

fill capacity 4500 psi. Air cylinders less than 4000 psi shall be exchanged 

for a full air cylinder.

AIR CYLINDER 

All 45-minute air cylinders for use in the field have a two inch luminescent band at the 

upper end of the cylinder. Printed three times within the band is the Los Angeles County’s 

three letter designator, LAC. The color of the letters indicates the date of manufacture 

and original hydrostatic test. The color rotation will repeat every five years as hydrostatic 

testing on carbon-fiber air cylinders is required every five-years.

FIRST-STAGE REGULATOR 

The first-stage regulator is housed and protected within 

the backpack assembly. It connects to the air cylinder 

valve using a high pressure hose and a large, easy-togrip 

stainless steel hand wheel. The stainless steel 

hand wheel provides a positive connection reducing the 

risk of cross threading or thread damage. The first stage 

regulator lowers air cylinder pressure to approximately 

115 psi, which is supplied to the second stage regulator 

via the intermediate pressure hose. A relief valve 

activates to protect the system should the regulator 

pressure exceed 200 to 225 psi. 

Ahi h ti f th HUD t d 

A high-pressure connection for the HUD transducer, 

UAC, and the remote Pressure Gauge/PASS Alarm on 

the right shoulder are all housed and protected within the 

backpack assembly.

LOW AIR ALARM 

The integrated low air warning alarm emits an audiblewarbling 

whistle when the air cylinder pressure reaches 

1035 to 1215 psi. (23 to 27 percent of the rated capacity 

of fthe air cylinder) The low air-warning i whistle will operate 

until air cylinder pressure drops below 200 psi. The 

whistle is located in the upper left corner of the backpack 

and is protected by the thermal and impact resistant 

enclosure.

AIR PRESSURE GAUGE/PASS ALARM 

A high pressure air hose is routed over the right shoulder strap 

and attach to the Air Pressure Gauge/PASS Alarm assembly. 

The gauge is luminescent for low light viewing and indicates 

the quantity of air remaining in the air cylinder once the air 

cylinder valve is opened. Air pressure is illustrated t from full 

“F” to empty “E” using quarter increments “¼ ½ ¾” similar to a 

fuel gauge on a vehicle. 

Opening the air cylinder valve arms the PASS device as air 

pressurizes the system. An ascending tone and alternating 

green flashing LED lights indicate activation. The PASS device 

can be manually triggered to full alert by depressing and 

holding the red alarm button for 1 to 2 seconds. 

Once the PASS reaches full alert, it can only be reset to normal 

operation by two slow and deliberate clicks of the yellow reset 

button the side of the housing. Reset is indicated by a 

descending tone. Two additional slow and deliberate clicks of 

the yellow reset button will shut-off the PASS device if the air 

has been bleed from the system.

AIR PRESSURE GAUGE/PASS ALARM 

Lack of movement will start the staged alarm in approximately 

20 seconds. The LED lights will alternate flashing green and 

red. The alarm will increase in volume approximately every 5 

seconds until full alert at 30 to 35 seconds. In full alert, the 

LED lights flash red and the alarm tones alternate between the 

front and rear mounted piezo speakers. 

The PASS device is powered by the 4 C-cell batteries in the 

backpack. An amber LED in the PASS device acts as the 

battery status indicator for the front of the SCBA.

SECOND STAGE REGULATOR 

The second stage regulator attaches to the facepiece using 

the Air Klic system. This mechanism automatically locks 

when the regulator is pushed into the Air Klic on the 

facepiece. The second stage regulator is activated by the 

First Breath On mechanism or by the manual override button 

on the front of the regulator. To disengage the regulator 

from the facepiece two steps need to be followed. First, 

press the black rectangular shut-off button at the twelve 

o’clock position on the regulator to stop the air supply. 

Second, depress both opposing gray release buttons at the 

twelve and six o’clock positions and pull the regulator from 

the facepiece.

SECOND STAGE REGULATOR 

The second stage regulator is capable of supplying the user 

in excess 350 liters per minute of breathing air. The large red 

knob on the regulator controls the adjustable bypass valve. 

Turning the bypass valve knob counterclockwise provides a 

constant flow of breathing air. The bypass valve is intended 

for emergency use only to supply breathing air should 

regulator failure occur. The bypass valve is capable for 

supplying a maximum of 130 liters per minute of breathing air. 

When not in use the regulator should be stored in the 

regulator belt clip located on the left waist strap. The second 

stage regulator supplies breathing air via an intermediate 

pressure hose with a quick connect fitting.

HEADS-UP DISPLAY (HUD) 

The HUD is mounted as part of the second stage regulator. 

When the second stage regulator is attached to the 

facepiece, the HUD display is visible through opening in the 

facepiece nozzle cover. When the air cylinder valve is 

opened, the HUD will activate automatically, and indicate the 

pressure available in the air cylinder. The display consists of 

four green LED’s indicating from right to left, Full, ¾, ½, and 

¼. A cylinder at 4500 psi will illuminate all 4 green LED’s. As 

the pressure in the air cylinder decreases, the LED’s turn off 

one at a time for each ¼ (25%) drop in air cylinder pressure. 

When the pressure drops below 50% of air cylinder capacity, 

the LED representing ½ cylinder capacity starts to blink. The 

blinking will continue for approximately 20 seconds before 

returning to constant illumination.

HEADS-UP DISPLAY (HUD) 

When the pressure drops below 25% of air cylinder capacity, 

the LED representing ¼ cylinder capacity changes color to 

red and starts to blink. A corresponding red LED on the front 

of the HUD will blink warning others of the users low air 

supply. When the pressure drops to 10% of air cylinder 

capacity, the LED representing ¼ cylinder capacity blinks 

noticeably faster. The LED on the front will also increase is 

blinking rate. The increased rate of blinking will continue until 

air cylinder pressure drops below 200 psi at which time the 

HUD will shut-off. 

A photodiode on the top of the HUD adjusts the green LED 

intensity so they are not a distraction to the user.

FACEPIECE 

The Warrior SCBA 20/20 facepiece is made of butyl 

rubber which enables it to pass the CBRN 

certification test. It has a wide lip sealing surface 

and four point adjustable head net harness. The 

poly-carbonate lens is treated t with an abrasion 

resistant coating on the outside, and an anti–fog 

solution on the inside. 

Breathing air from the second stage regulator enters 

the facepiece and is directed onto the polycarbonate 

lens. The cool air allows the lens to 

withstand the heat and flame impingement tests 

required for NFPA compliance. The integrated nose 

cup allows fresh air to enter the nose and mouth 

while capturing exhaled air and routing it through the 

exhalation valve, minimizing CO2 retention in the 

facepiece and reducing lens fogging. The nose cup 

also houses the speaking diaphragm and 

microphone for the Voice Projection Unit. 

The air klic port is threaded into the housing by a ratchet mechanism to prevent leakage and provide a secure 

mount for the second stage regulator. 

The 20/20 facepiece should not be stored in direct sunlight. Sunlight has a degrading effect on butyl 

rubber and nomex materials.

VOICE PROJECTION UNIT (VPU) 

The Voice Projection Unit is designed to facilitate verbal 

communication while wearing a facepiece. The unit provides 

the wearer a choice of brief or constant voice amplification by 

pushing the power button on top of the VPU. One depression 

of the power button activates the VPU for two seconds. Two 

consecutive pushes of the power button activates the VPU for 

continuous use. 

A red LED light is visible to the user on the right side of the 

facepiece to indicate the unit is on. An amber LED light will 

blink to warn the user of a low battery. The VPU is powered 

by three AAA batteries and 

The VPU is powered by three AAA batteries and can be 

changed in the field by opening the battery compartment door 

at the front of the housing. 

Two more consecutive pushes of the power button will turn 

the VPU off. The VPU attaches to the right side of the 

facepiece using an alignment tab and a threaded knurled 

knob. Electrical contacts connect the VPU to the microphone 

located within the facepiece. The amplifier’s low attachment 

location minimizes obstruction of the wearer’s vision, and its 

ergonomic controls allow operation with a gloved hand.

INFORMATION LIGHTING 

A LED informational lighting component has been added to the 

Warrior SCBA to allow the user and surrounding crew members to 

assess each unit’s status. All lighting on the backpack assembly 

are located on the right and left side of the air cylinder. Lighting on 

the front of the SCBA is located on the second-stage regulator and 

PASS device. 

Amber LED’s on the upper right rear of the backpack and the front 

PASS device blink once every 10 seconds to indicate a usable 

battery condition. Blinking every two seconds indicates a low 

battery condition. If a low battery condition occurs during use, an 

amber LED on the HUD will blink every second. The SCBA may 

continue to be used and the batteries shall be replaced before the 

next usage.

INFORMATION LIGHTING 

A red LED above the battery status light will blink went the 

user’s remaining air supply has reached ¼. This will occur 

approximately at the same time the audible low air alarm is 

activating. A corresponding red LED on the front of the HUD 

will blink warning others of the users low air supply. 

Two LED’s, one on each side of the air cylinder act as a 

visual reference to the PASS device operation. During 

normal operation, alternating green LED’s will blink once 

every second. The LED lights will alternate blinking green 

and red as the PASS device begins its staged operation. At 

full alert, the red LED’s will blink once every second.

UNIVERSAL AIR CONNECTION (UAC) 

The Warrior SCBA comes equipped with the Rapid 

Intervention Crew / Universal Air Connection (RIC UAC). 

Located on the lower left side of the backpack, the UAC 

has a dust cover that must be used at all times. 

Connection to the UAC via the mating fill coupling allows a 

one direction flow of air into the user’s air cylinder. A 

directional flow control piston is located in the quick 

disconnect coupling to prevent accidental air loss. A relief 

valve is designed to vent air to atmosphere if the fill 

pressure exceeds the air cylinder service pressure. 

The UAC is intended for refilling of an air cylinder under an emergency situation. It must never be 

used as a Buddy Breathing device, for SCBA to SCBA filling, or as a continuous air supply.

EMERGENCY BREATHING 

SAFETY SYSTEM (EBSS) 

The Emergency Breathing Safety System is 

designed to allow connection to a supplied air 

line or another EBSS. It is intended to supply 

EMERGENCY AIR to a fire fighter who has 

become lost, trapped, or disoriented in an IDLH 

environment. The EBSS is located in a storage 

pouch on the wearers left hip and consists of a 

39 inch intermediate pressure hose and a “Y” 

block with a male and female quick connect. 

When two SCBA’s are connected using the Emergency Breathing Safety System there is no transfer of air. 

The SCBA with the higher intermediate pressure will automatically supply both SCBA’s until that air is 

exhausted. At that point air in the SCBA that had the lower intermediate pressure will supply air both SCBA’s. 

The users will have no way of knowing which air cylinder will be supplying the air initially unless they are 

monitoring theIr air cylinder pressure gauges. g 

The acceptable range for setting intermediate pressure is 80 to 150 psi. This is set by the manufacturer and 

can only be adjusted by repair personnel. This pressure range is more than capable of maintaining positive 

pressure to the facepieces of both fire fighters.

WARRIOR SELF-CONTAINED BREATHING APPARATUS 

INSPECTION, TESTING, CLEANING AND SANITIZING 

DAILY INSPECTION: Warrior SCBA’s shall be visually inspected at the beginning of each duty day and after 

each use. After completing the inspection, initial and note the air cylinder pressure on the appropriate Form-20 

BACKPACK HARNESS AND FRAME: Assure that air cylinder is properly secured and that stainless air cylinder 

strap and latching mechanism are working properly. Inspect the backpack frame for bends, breaks and cracks. 

Check the harness assembly for discoloration, excessive wear or fraying, cuts, or damaged stitching. Check all 

buckles for damage or corrosion. All straps should be stored fully extended to allow rapid donning. Check battery 

condition by observing blinking amber LED. 

AIR CYLINDERS: Check air cylinder pressure; change the air cylinder if the pressure is below 4000 PSI. Inspect 

the exterior of the cylinder for dents, gouges, or cuts which have penetrated and caused separation of the 

composite over-wrap. Check for evidence of exposure to high temperature, such as darkened or blistered paint, 

or charred composite over-wrap. The cylinder valve should also be examined for obvious external damage. 

FIRST STAGE REGULATOR CONNECTION: Check hand wheel for a snug connection to the air cylinder valve. 

The high pressure hose should show no signs of separation. 

PRESSURE HOSES: Inspect all rubber hoses for cracking, obvious physical damage, and separation at the 

connections. Check hoses for secure attachment to the frame at the top of the backpack. Inspect the braided 

stainless air line for separation at the couplings, fraying, and kinks. The quick connect fitting on the intermediate 

pressure hose should be properly connected.



SECOND STAGE REGULATOR: Fully depress the shutoff button on the second stage regulator and check that 

the red bypass knob is in the closed position. Inspect for cracks or damage to the regulator housing. Check for dirt 

or debris in the air outlet port and cracks in the screen and grill. Dirt and debris can be cleared by opening the air 

cylinder valve and the bypass valve with the outlet port facing down. Check both gray release buttons for proper 

operation and good spring tension. Assure HUD display lights are fully visible. 

GAUGE: Inspect the gauge lens for cracks, the gauge pressure indicator should point to the red empty area with 

the air cylinder valve off. 

FACEPIECE: Inspect the lens for scratches and abrasions that significantly impair visibility. Any evidence of heat 

deformity to the lens is cause for immediate removal form service and inspection by the SCBA Repair Shops. 

Check the facepiece body, sealing skirt, and five point head net for nicks, tears, pliability, and damage from age, 

heat, or contamination. The five point head net should be stored fully extended to allow rapid donning. Inspect 

the air inlet port for damage and dirt. 

VOICE PROJECTION UNIT: Inspect the Voice Projection Unit (VPU) for cracks or damage. Ensure that the unit 

is securely attached to the facepiece. Turn on the VPU and visually check the red LED light for operation, a 

flashing amber light indicates low battery power, replace the three AAA batteries. Place the facepiece to your face 

and speak to check amplification function. The Voice Projection Unit shall be turned off for storage. 

PASS DEVICE: Inspect the PASS Device for cracks or damage. Ensure that the unit is securely attached to the 

dual quick connect fitting. Manually activate the PASS, note the ascending tone and green flashing LED lights. 

Allow the PASS to cycle to full alert; the LED lights should flash green and red as the alert tone increases in 

volume. At full alert the LED lights should flash red. Turn off PASS device.



The weekly tests shall comprise all requirements of the daily inspection and include: 

Facepiece Leak Test 

1. Don and adjust the facepiece. 

2. Block the air klic opening with the palm of your hand. 

3. Inhale gently and your breath hold for 3 seconds, the facepiece should collapse slightly without leaking 

4. Keeping the air klic opening covered, exhale gently. 

5. The exhalation valve should open freely without sticking or fluttering.




SCBA Leak, Visual and Audible Alarm Test 

1. Insure the shut-off button and the bypass valve on the second stage regulator is in the off position. 

2. Open the air cylinder valve to fully pressurize the hoses and regulators. The PASS device should 

automatically activate, note the ascending tone and green flashing LED lights on the PASS and 

backpack. The low air whistle should sound briefly as the system pressurizes. 

3. Close the air cylinder valve. 

4. Observe the gauge/alarm for 10 seconds. 

5. Significant needle movement from air pressure loss indicates a system leak. The SCBA shall be sent for 

repairs. 

6. Slightly open the bypass valve and allow the system pressure to bleed down stopping at ¾, ½ and ¼. 

The indicator lights on the HUD take a few seconds to respond. At approximately the ¼ full mark on the 

pressure gauge, the audible low air whistle should sound and the red low air warning lights on the second 

stage regulator and backpack should blink. The audible whistle alarm should continue until the air is 

almost depleted. 

7. Bleed all residual air in the system and close the bypass valve. 

8. Allow the PASS to cycle to full alert, the LED lights should flash green and red as the alert tone increases 

in volume. At full alert the LED lights should flash red. The LED lights on the backpack should flash at 

the same rate and color as the PASS. 

9. Manually click the on/off button twice to turn the PASS device off.




SCBA Function Test 

1. Insure the shut-off button has been depressed and the bypass valve on the second stage regulator is 

turned to the off position. 

2. Open the air cylinder valve and check that the cylinder valve gauge and gauge on the PASS device both 

indicate a pressure of 4000 psi or more. 

3. Don facepiece and check for a proper seal. 

4. Attach the second stage regulator to the facepiece and inhale. The regulator should activate 

automatically delivering an acceptable airflow without excessive breathing effort, free flow, or fluttering. 

5. Slowly open the bypass valve. A steady flow of air should enter the facepiece. 

6. Close the bypass valve and depress the shut-off button on the second stage regulator. Airflow should 

stop. 

7. Push the manual override button. A small burst of air should enter the facepiece and the regulator should 

activate. 

8. Depress the shut-off button and remove the facepiece. Close the cylinder valve and bleed all residual air 

from the system using the bypass valve. Manually click the on/off button twice to turn the PASS device 

off.



CLEANING AND SANITIZING 

**All SCBA’s shall be cleaned and sanitized after each use. 

**Always remove the Voice Projection Unit and Second Stage Regulator prior to rinsing or immersing the 

facepiece in water, cleaning solution, or disinfecting solution. 

Facepiece Cleaning and Sanitizing 

1. Make a cleaning solution of warm (110 degrees F maximum) water and mild soap or Simple Green D. 

Industrial cleaners like Zep, Hilite Suds, or any cleaner containing ammonia will remove the antifog 

coating and shall not be used. 

2. Immerse the facepiece top first in the solution until the exhalation valve is covered. Agitate the facepiece 

and gently clean with a soft brush if necessary. 

3. Thoroughly rinse the facepiece in fresh water, paying particular attention to removal of all soap residue 

from the exhalation valve. If possible, direct running water onto the exhalation valve. 

4. Make a hypochlorite disinfecting solution of 2 tablespoons of chlorine bleach per gallon of warm (110 

degrees F maximum) water. 

5. Immerse the facepiece top first in the solution until the exhalation valve is covered. Soak the facepiece 

for 2 to 3 minutes. 

6. Thoroughly rinse the facepiece in fresh water, paying particular attention to removal of all soap residue 

from the exhalation valve. If possible, direct running water onto the exhalation valve. 

7. Allow the facepiece to drip dry. A clean lint free cloth may be used to dry exterior surfaces. Do not use 

compressed air at any time. 

8. Once the facepiece is completely dry, hold the facepiece firmly against your face. Cover the air klic 

opening with the palm of your hand and exhale several times to ensure that the exhalation valve functions 

smoothly.







Second Stage Regulator Cleaning 

1. Always hold the regulator with the outlet tube facing downward and the protective cleaning cap installed 

during washing and rinsing. Dirt or soap residue could degrade regulator performance. Do not allow water 

to enter the breathing air opening on the regulator. Do not submerge regulator in water or cleaning 

solution. Do not allow water to enter the intermediate pressure hose at the male quick connect 

fitting. 

2. Make a cleaning solution of warm (110 degrees F maximum) water and a mild soap. 

3. Install the red second stage regulator cleaning cap. 

4. With the regulator facing downward, scrub the exterior surfaces with the cleaning solution and a soft brush. 

5. Immediately rinse the exterior surfaces with fresh water, again holding the regulator facing downward. 

6. Thoroughly rinse all excess soap and dirt from the regulator. 

7. Remove the second stage regulator cleaning cap. If water entered the second stage regulator while 

8. cleaning, flow the regulator and bypass to expel all moisture. 

9. Using a damp, lint-free cloth, clean the interior of the outlet tube. Dry the exterior with a clean cloth or let 

air dry.







Backpack Harness Assembly Cleaning 

1. The backpack harness assembly is comprised of the aluminum frame and internal components, 

hoses, shoulder and waist strapping, pressure gauge/PASS g assembly, air fitting/HUD connection, 

and the air cylinder. 

2. When possible all components should be cleaned using only a damp cloth. 

3. If more extensive cleaning is required, make a cleaning solution of warm (110 degrees F maximum) 

water and a mild soap. Industrial cleaners like Zep, Hilite Suds, or any cleaner containing 

chlorine bleach will damage the Nomex/Kevlar harness and shall not be used. 

4. Clean all components using a soft brush and cleaning solution. Always have the air cylinder 

attached to the high pressure connection during cleaning to keep water or cleaning solution from 

entering the system. 

5. Rinse thoroughly and air dry or wipe with a clean cloth.
