Factors that Affect the Service Life of the SCBA
CAUTION!
The service life of the SCBA is greatly reduced when the regulator bypass is used.
The following factors can affect the duration or service life of the equipment:
7.2
•
Your average degree of physical activity
•
Your general physical condition
•
The degree to which your breathing rate is increased by excitement, fear, or other emotional
factors
•
Your degree of training or experience with this or similar equipment
•
Whether the cylinder is fully charged
•
The concentration of carbon dioxide in the compressed air more than the 0.04 percent level
normally found in atmospheric air
•
Atmospheric pressure: the service life of the SCBA is based on 1 atm (101,325 Pa) of pressure. If
used in a pressurized tunnel or caisson at 2 atm (202,650 Pa), the service life of the SCBA will be
half as long as when it is used at 1 atm (101,325 Pa). At 3 atm (303,975 Pa), the service life will
be one-third as long.
•

Before going into a hazardous environment, make sure there is no water, moisture, or dampness
on or in any of the SCBA components. Any moisture on or in the SCBA components can freeze
and result in a malfunction of the SCBA. Make sure all components operate correctly.
Before going into a hazardous environment, make sure there is no water or ice on the inner
surfaces and components of the regulator, regulator buttons, and bypass valve. Make sure the
buttons and bypass valve operate correctly.
Do NOT use a regulator that has water contamination on the inner surfaces or components.
Remove the regulator from service, and dry all surfaces and components fully. Make sure all regulator components are fully dry before returning the regulator to service.
Failure to obey these warnings can result in serious personal injury or death.
7.3.1 All SCBA
•
Any water on or in the SCBA components can freeze and restrict airflow. To keep moisture from
entering the regulator, keep the regulator in the regulator keeper when it is not in use.
•
When the SCBA is away from heat, water spray can freeze on the regulator surface. Ice can build
up and bind the side buttons or the bypass valve. Before entering or re-entering a hazardous atmosphere, make sure there is no ice on the side buttons or bypass valve, and that they operate
correctly.
•
Periodically make sure there is no ice on the bypass valve.
•
Moisture can enter through the cylinder valve or coupling nut when cylinders are replaced on the
SCBA. When replacing cylinders, make sure moisture or contamination does not enter the system.
Remove any ice from these fittings.
•
Wipe the coupling nut threads and cylinder valve threads before installing a new cylinder. Water
can contaminate the system and freeze.
•
When cleaning the SCBA, make sure water does not enter the facepiece or regulator.
•
Thoroughly dry the facepiece and facepiece mounted regulator after cleaning and disinfecting.
Obey the Confidence Plus® Cleaning Solution instructions.
•
The latch can freeze when moist. Clean and dry the latch before storing the SCBA at low temperatures.
•
If moisture gets on the dove tail, the cylinder could get stuck in the dove tail if it freezes. Clean and
dry the dove tail before storing the SCBA at low temperatures.
•
Make sure that the UAC dust cap is in place before storing the SCBA.
US
Moisture can cause problems in the SCBA if it freezes. However, moisture can cause freezing problems even if the surrounding air is above freezing. Air flowing from the cylinder through the pressure
reducer and regulator decreases from cylinder pressure to close to atmospheric pressure very quickly.
This causes the air to expand and creates a cooling effect. Although the surrounding temperature may
be warmer than 32°F (0°C), the temperature inside the regulator may be lower.
Prior to storage of the SCBA at temperatures below 0°F (-18°C), verify that the alkaline battery module
has new batteries and that the rechargeable battery module is fully charged.

9.3.1 Thermal Alarm
WARNING!
Although the thermal alarm provides an indication that the temperature/time curve is exceeded,
because of variations in individuals and protective clothing, the curve may not represent the threshold
to injury accurately. Use the thermal alarm only as a reference to increasing temperature/time. Do not
use the thermal alarm as a substitute for standard operating procedures for escape from temperature/
time extremes.
Failure to obey this warning can result in serious personal injury or death.
If the option for the thermal alarm is activated, the control module monitors thermal conditions. The
thermal alarm can be set as a primary or secondary (default) alarm. If the user is exposed to more
than the preset limit of thermal load (temperature/time), the secondary alarm shows on the control
module and the power module emits a tone every 5 seconds.
The following figure shows the thermal alarm activation curve for the control module. The temperature/time limits correspond to this graph. The thermal alarm activates if the preset limit exceeds the
curve shown on the graph. Depending on the severity of conditions, the alarm will self-cancel. This
may occur even though the temperature is above the thermal curve.
US
NOTE: This chart was generated from data obtained in a laboratory setting and is for reference only.
Conditions are highly variable in an actual-use scenario. Users of the thermal alarm option should
develop procedures for the use of this feature.
9.3.2 Secondary Alarm Icons
The secondary alarm icons indicate that a thermal alarm, battery alarm, or loss of radio connection
occurred. These icons show on the primary screen until the condition is corrected (for example, the
radio connection is re-established).
The evacuate alarm can only be cleared by restarting the SCBA.

ID Tagging
WARNING!
When scanning an ID tag, make sure the ID tag touches the power module. If it does not, the PASS
device can lock up. If a lockup occurs, remove the battery module from the SCBA, wait 30 seconds,
and then install the battery module.
Failure to obey this warning can result in serious injury or death.
Before use, make sure the ID tag does not have cracks or other damage. If the ID tag is damaged,
discard it and replace it with a new ID tag.
US
9.4.1 Name ID Tag
A name ID tag (P/N 10083875) is used to assign a user's name to an SCBA. By default, the name ID
tag must be scanned into the power module at the start of each shift (every 24 hours) or before each
use. The name assigned to the SCBA shows on the MSA A2 accountability system software and the
data log within the SCBA.
For more information about ID tags, or to change the default setting so a name ID tag can be assigned
permanently to the SCBA (until a new name ID tag is scanned), refer to the Operating Manual: MSA
A2® Software, Accountability Control Software (P/N 10162374).
9.4.2 Team ID Tag
A team ID tag is used to assign a team/truck and position to an SCBA. If a team ID tag is scanned into
the power module but a name ID tag is not, the team ID will show on the MSA A2 accountability system
software. When a team ID tag is scanned into the power module, the team ID stays with the SCBA
until another team ID tag is scanned. If a team ID or name ID has not been assigned to the SCBA, the
power module serial number shows as the firefighter's ID when the SCBA is logged onto the base
station.
G1 SCBA 2018 Edition
53
Control Module
9.4.3 Base Station ID Tag
A base station ID is used to assign a specific base station ID to an SCBA. When more than one base
station is available and actively monitoring at an incident, an SCBA with an assigned base station
searches first for the preferred base station to log onto. If the SCBA does not find the assigned base
station within 20 seconds, it searches for the first available base station and logs onto it. If a base
station ID has not been assigned to the SCBA, the SCBA logs onto the first base station it finds after
being turned on. When a base station ID tag is scanned into the power module, the base station ID
stays with the SCBA until another base station ID tag is scanned.
9.4.4 During Use
The user can assign a tag to the SCBA during use.
(1)

US
NOTICE


Do NOT use a pressure washer or fire hose to clean the SCBA.
If it is a requirement of local fire department procedures to use a fire hose to do decontamination
at the fire scene before a firefighter removes the SCBA, make sure to decrease the pressure of the
fire hose to prevent damage to the equipment.
Use a ½ in. water hose connected to a water supply source.
Failure to obey these notices can cause damage to the SCBA components.
Water/moisture can cause problems in the SCBA if it freezes. Water/moisture can cause freezing
problems even if the surrounding air temperature is above 32°F (0°C). Air flowing from the cylinder
through the pressure reducer and regulator decreases from cylinder pressure to close-to-atmospheric
pressure very quickly. This causes the air to expand and creates a cooling effect. Although the
surrounding temperature may be warmer than 32°F (0°C), the temperature inside the regulator may
be lower. Any water, moisture, or dampness inside can freeze and restrict airflow.
Do the following when using a water hose to clean and disinfect the SCBA:

12.1 Safety Precautions for MSA SCBA Cylinders
WARNING!






To maintain NIOSH approval, cylinders must be fully charged with respirable air that meets the
requirements of CGA G-7.1, Section 2.1, Quality Verification Levels (Grades) D, or higher quality
air, with a moisture dew point not more than -65°F (-54°C) (24 ppm water vapor, normal). In fire
service applications, MSA recommends breathing air quality in accordance with NFPA 1989, Standard on Breathing Air Quality for Emergency Services Respiratory Protection.
Do NOT drop the cylinder or hit the handwheel. An unsecured cylinder can become an airborne
projectile under its own pressure if the cylinder valve is opened even slightly.
Do NOT use the handwheel to carry or move a cylinder. If a cylinder is removed from a horizontal
shelf by grasping the handwheel, the weight of the cylinder can cause the cylinder to turn downward, causing the valve to open slightly.
Use the handwheel only to open and close the cylinder valve.
Remove the cylinder from service if it shows evidence of exposure to high heat or flame, such as
paint that has turned a brown or black color, decals that are charred or missing, a melted gauge
lens, or distorted elastomeric materials.
Use this SCBA only after receiving the correct training. Use this SCBA in accordance with the MSA
instructions.

Do NOT use cylinders that are not filled to the maximum working pressure.

Do NOT alter, modify, or substitute any components without approval of the manufacturer.

Examine the cylinders frequently.

Maintain cylinders in accordance with the manufacturer's instructions.

Return cylinders to an MSA trained and certified repair technician for repair.
Failure to obey these warnings can result in serious injury or death.
Recharge SCBA cylinders fully as soon as possible after use.
US
Do NOT put cylinders that are partially charged in storage.
•
The service time of the SCBA is reduced if cylinders that are partially charged are used.
•
The pressure-relief device is only designed to protect a fully charged cylinder from the effects of a
fire.
For maximum safety, store the cylinders full or at a pressure above ambient but less than 100 psi.
Before recharging, examine the cylinders externally for evidence of high heat exposure, corrosion, or
other significant damage.
When performing external and internal inspections of the cylinders, refer to the latest edition of CGA
C-6.2, Standard for Visual Inspection and Requalification of Fiber Reinforced High Pressure Cylinders.
If there is any doubt about the suitability of the cylinder for recharge, return it to a certified hydrostatic
test facility for expert examination and testing.
Make sure the retest date is within the prescribed period and that the cylinder is correctly labeled to
indicate its gaseous service. New labels are restricted items that are not available except through
certified hydrostatic test facilities.
G1 SCBA 2018 Edition

UAC Fitting
13
UAC Fitting
The universal air connection (UAC) fitting is a male coupling for use by rapid intervention teams for
emergency filling operations. In accordance with the requirements of NFPA 1981, Standard on OpenCircuit Self-Contained Breathing Apparatus (SCBA) for Emergency Services, the SCBA is equipped
with one RIC UAC fitting located on the pressure reducer. The SCBA can be equipped with an optional
Remote Quick-Fill system that includes an additional UAC fitting. For SCBA with 2216 or 4500 psi
systems, either the RIC UAC fitting or the Remote Quick-Fill UAC fitting can be used for the filling and
transfilling operations described in this manual. SCBA with a 5500 psi operating system will not transfill.
Users are responsible for developing standard operating procedures for use of the UAC fitting.
13.1 Precautions
WARNING!




Do NOT use the UAC fitting if there is any possibility that the environment contains a CBRN
warfare agent. The UAC fitting is not approved for filling operations in atmospheres containing
CBRN warfare agents.
Do NOT use the UAC fitting as a buddy breather (two users sharing the air supplied by one
approved SCBA cylinder simultaneously). Doing so voids NIOSH approval.
Do NOT try to transfill SCBA with a 5500 psi operating system.
Only qualified, trained personnel who have carefully read and understood these instructions,
cautions, and warnings should use the UAC fitting.

Do NOT lubricate the UAC fittings.

Do NOT let oil, grease, or other contaminants have contact with the UAC fittings.

For transfilling air from a secondary air supply, the hose assemblies and fittings are designed to be
used with CGA G-7.1, Section 2.1, Quality Verification Levels (Grades) D, or higher quality air. In
fire service applications, MSA recommends breathing air quality in accordance with NFPA 1989,
Standard on Breathing Air Quality for Emergency Services Respiratory Protection.
Failure to obey these warnings can result in serious injury or death.
US
The UAC fitting can only be used to fill approved SCBA cylinders.
The user is responsible for the air supply, which must meet the requirements of CGA G-7.1,
Section 2.1, Quality Verification Levels (Grades) D, or higher quality, with a moisture dew point not
more than -65°F (-54°C) (24 ppm water vapor, normal). In fire service applications, MSA recommends
breathing air quality in accordance with NFPA 1989, Standard on Breathing Air Quality for Emergency
Services Respiratory Protection.
Pressures at the inlet of the Quick-Fill hose must not exceed that of the SCBA (2216 psi, 4500 psi,
5500 psi).
The user is responsible for connecting the Quick-Fill hose to an appropriate secondary air supply.
Examine the cylinder for damage before charging.
When topping off the cylinder pressure using the UAC fitting, MSA recommends waiting until the
cylinder has cooled from the initial fill to a temperature of 70°F (21°C) to provide the maximum service
time.
To make sure the SCBA is in a configuration approved by NIOSH 42 CFR Part 84, use only MSAapproved hose assemblies during transfilling procedures.

13.2 Filling Instructions
WARNING!
Do NOT connect a high-pressure SCBA to a secondary air supply with a pressure more than the operating system of the primary SCBA.
Failure to obey this warning can result in serious injury or death.
A secondary air supply provides compressed breathing air when it is needed to refill SCBA air cylinders. For filling operations, the pressure of the secondary air supply must be more than the SCBA
cylinder pressure. Examples of air supplies include cascade air cylinder refilling systems, high-pressure compressor systems with a fixed reservoir, and portable air systems such as the RescueAire® II
System.
NOTE: Rapid intervention teams should use a separate air supply such as MSA's RescueAire II
Portable Air-Supply System (P/N 10100095) to fill the SCBA cylinders in atmospheres that are IDLH.
(1)
Connect the Quick-Fill hose to the secondary air supply.
(2)
Turn the air supply on.
NOTICE
If there is leakage from either female fitting or along the Quick-Fill hose, depressurize the hose and
correct the problem. Such leakage can result in increased fill time.
(3)
US
Attach the Quick-Fill hose to the UAC fitting:
a) Remove the rubber dust cap from the male inlet fitting on
the UAC fitting. Make sure the cylinder valve is fully
open.
b) Remove the rubber dust cap from the female fitting on
the Quick-Fill hose.
c) Push the female fitting of the Quick-Fill hose onto the
male fitting of the UAC until the hose clicks into position.
d) Pull on the Quick-Fill hose to make sure the connection
is secure.
When the female fitting of the Quick-Fill hose fully engages
with the UAC fitting, filling starts immediately.
After approximately 60 seconds, the pressure between the
secondary air supply and the SCBA cylinder will be equal.
G1 SCBA 2018 Edition
73
UAC Fitting
NOTE: If the secondary air supply does not have a sufficient volume of air, the SCBA cylinder will not
reach full service pressure.
(4)

(7)
Immediately install the rubber dust cap on the UAC fitting.
(8)
If the needle on the cylinder pressure gauge is in the appropriate color band, the SCBA cylinder
is ready for service.
13.3 Transfilling between SCBAs
WARNING!


Do NOT try to transfill SCBA with a 5500 psi operating system.
Do NOT do transfilling between SCBAs if the donor's primary low-pressure warning device is in
alarm or the HUD/control module lights are flashing red.
Failure to obey this warning can result in a shorter escape time to return to fresh air, causing
serious personal injury or death.
Do transfilling between SCBAs ONLY during life-threatening emergencies or simulated training exercises.
US
The SCBA with the higher pressure reading is the donor. The SCBA with the lower pressure reading
is the receiver. Both donor and receiver must return to fresh air immediately following the transfilling
procedure.
If the donor's primary low-pressure warning device goes into alarm or the HUD/control module lights
start to flash red during transfilling to indicate that pressure in the cylinder has been reduced to
35 percent of its rated working pressure, the donor should disconnect and use the remaining service
time to escape to fresh air.
If the donor's primary low-pressure warning device is not in alarm, the HUD/control module lights are
not flashing, and there is sufficient air to transfill to a receiver (more than 1000 psi for 2216 psi SCBAs
and more than 2000 psi for 4500 psi SCBAs), do the following:
G1 SCBA 2018 Edition




Do NOT connect the ExtendAire II system if there is any possibility that the environment contains
a CBRN warfare agent. The ExtendAire II system is not approved for connection in atmospheres
containing CBRN warfare agents.
The ExtendAire II system has UEBSS quick-connect fittings. Do not try to connect Snap-tite quickconnect fittings to UEBSS quick-connect fittings. Snap-tite and UEBSS quick-connect fittings will
not operate correctly together.
Do NOT install or try to use any hose assembly or fitting other than those supplied by MSA for the
ExtendAire II system with UEBSS fittings.
In accordance with NFPA 1981-2018, the MSA G1 SCBA has UEBSS fittings that make it possible
to connect to a UEBSS on other manufacturers’ SCBAs. Approval under the NFPA 1981-2018
standard does not require testing with other manufacturers’ devices. When the UEBSS fittings are
used to connect the MSA G1 SCBA with another manufacturer’s device, MSA does not guarantee
or warrant the performance of either the MSA G1 SCBA or the other manufacturer’s SCBA.
Users must be trained in the operation of ExtendAire II system in accordance with a training
program conforming to NFPA 1404, Standard for Fire Service Respiratory Protection Training, and
NFPA 1500, Standard on Fire Department Occupational Safety and Health Program, before any
attempt to use such equipment in an emergency situation.
Users are responsible for developing standard operating procedures for use of the ExtendAire II
system.
Use this emergency escape breathing system only for life-threatening emergencies and simulated
training exercises. Consider all other adequate means of escape before using this device.
Use of the ExtendAire II system in either donor or receiver mode changes the use of the SCBA to
Escape Only. The donor and receiver must immediately return to fresh air.
During use, the air supply and consequentially the remaining service time are decreased by
approximately half. Before connecting two users, make sure the donor’s air supply is sufficient for
both users to escape. Otherwise, do not use the system.
US
Do NOT use the system if the donor's low-pressure warning device is in alarm. Use of the system
at this time can result in insufficient air for both users during escape.
Before disconnecting the EBSS, make sure that the cylinder valves for both the donor and receiver
are open.
Use extreme care while the air masks are connected. Mobility and range of motion are limited
when donor and receiver air masks are connected.
Keep slack in the air lines. Do NOT pull on the hoses. Pulling on the rescue hose to the intermediate pressure hose can cause the hoses to separate from the fittings and result in air leaks.
If users cannot follow the previous instructions, or to provide increased escape protection, use the
Quick-Fill system. Use of the Quick-Fill system maintains approval during transfilling procedures
and has fewer safety risks.
Failure to obey these warnings can result in serious personal injury or death.
The ExtendAire II system lets two users connect and share intermediate-pressure air. The
ExtendAire II system includes a manifold, hose assembly, and pouch. In accordance with the requirements of NFPA 1981, Standard on Open-Circuit Self-Contained Breathing Apparatus (SCBA) for

Flow Test and Overhaul Requirements
15
Flow Test and Overhaul Requirements
The regulator and primary low-pressure warning device must be flow tested at specific time intervals
by a certified repair technician or at an MSA service center. Contact your MSA sales representative
or call the MSA Customer Service Center at 1-877-MSA-3473 for more information about this requirement.
Annual flow tests are a requirement of NFPA 1852, Standard on Selection, Care, and Maintenance of
Open-Circuit Self-Contained Breathing Apparatus (SCBA), 2019 edition. Although this standard
relates to SCBA used in the fire service, MSA requires that a flow test be done at least annually on all
SCBA and combination respirators that use a regulator.
MSA recommends the routine inspection of all elastomeric materials including, but not limited to,
those given in Section 4 "Visual Inspections" and Section 5 "Functional Tests".
A decision to remove apparatus from service permanently should be based on the SCBA's performance data and whether that data meets the specified level of performance defined in the MSA CARE
manuals.
MSA recommends overhauling the SCBA after every 600 hours of on-air usage. The SCBA service
mode provides the status of on-air usage. Only trained personnel are authorized to use service mode.
15.1 Overhaul Reminder
The G1 SCBA can be configured to show an overhaul alarm on the control module after 600 hours of

Telemetry Module
17
Telemetry Module
The telemetry module is designed to let the SCBA to communicate with a remote base station while
in use. SCBAs with a telemetry module transmit statistics such as cylinder pressure, thermal alarm (if
enabled), service time remaining, and PASS alarm to the base station. The base station can send an
evacuation command to the SCBA. The telemetry module uses a special version of the power module.
Except for the following differences, the operation of SCBAs with a telemetry module is the same as
for SCBAs without a telemetry module:
•
Turning the control module on: When the control module is activated in the presence of a remote
base station, the SCBA automatically starts to log onto that base station. When the SCBA is
successfully logged onto the base station, a radio link indicator shows on the display of the control
module.
•
Evacuation signal: After it has been successfully logged onto the base station, the SCBA can
receive an evacuation signal from the remote base station. When the base station sends an evacuation signal, the running man icon flashes on the display of control module and the power module
emits a unique audible alarm. The user must push the green RESET button twice within approximately 1 second to confirm the evacuation signal. When the evacuation signal is confirmed, the
running man icon stops flashing and shows steady on the display until the control module is turned
off.
•
PASS alarm: When the SCBA emits a full PASS alarm, a signal is automatically sent to the base
station to alert Incident Command.
•
Thermal alarm: When the SCBA is exposed to temperature conditions that activate a thermal
alarm (if enabled), a signal is automatically sent to the base station to alert Incident Command.
•
Low battery: When the power module gets to a low battery condition, a signal is automatically sent
to the base station to alert Incident Command.
•
Data log: The data logging feature of the control module logs the status of the radio link to the base
station as well as any evacuation signals the SCBA receives.
•
Radio link indicator: The control module has a radio link indicator on the secondary screen.
When this icon shows, the SCBA is logged onto a base station and within range. A red radio link
indicator means the radio contact has been lost or interrupted. A grey radio link indicator means
the radio contact was never established.
•
Turning the control module off: To turn the control module off, push the green RESET button
twice within approximately 1 second. If the SCBA is logged onto the base station, there is a slight
delay between the two pushes of the RESET button and the actual shutdown of the device while
the base station removes the SCBA from its registry.
G1 SCBA 2018 Edition

(1)
To activate the control module, open the cylinder valve or push and hold the ALARM button. An
icon representing the SCBA user shows on the computer screen of the base station.
(2)
When the base station makes contact with the SCBA and all initial information has been
obtained, the radio link indicator shows in the upper left corner of the control module display.
(3)
Monitor the status of the radio link indicator on the display of the control module. If the indicator
is yellow, the SCBA is out of range from the base station. When the SCBA is within range of the
base station, the radio link indicator is green.
17.1.2 Logging Off of the Base Station
When the user returns to fresh air, the control module can be turned off.
(1)
Turn the handwheel clockwise to close the cylinder valve.
(2)
Turn the regulator bypass knob counterclockwise to open the regulator bypass valve, or if
equipped, push the purge button, to release all pressure from the SCBA.
(3)
When the pressure decreases below 200 psi, push the RESET button twice in approximately
1 second to turn the control module off (sleep mode). If the SCBA is logged onto a base station,
there is a slight delay between the two pushes of the RESET button and the actual shutdown of
the device while the base station removes the SCBA from its registry.
US
17.2 Evacuation Signal
If the SCBA is logged on to a base station, Incident Command can send an evacuation signal to the
SCBA. When the base station sends an evacuation signal, the running man icon flashes on the display
of control module and the power module emits a unique audible alarm. The user must push the green
RESET button twice within approximately 1 second to confirm the evacuation signal. When the evacuation signal is confirmed, the running man icon stops flashing and shows steady on the display until
