Description
Description
The MSA G1 - referred to hereafter as SCBA - is a pressure-demand self-contained breathing apparatus (SCBA) operating independent of the ambient air for use in atmospheres immediately
dangerous to life or health.
Breathable air is supplied to the user from a compressed air cylinder via a pressure reducer, a regulator and a facepiece. The exhalation air is released directly into the ambient atmosphere.
The integrated personal alert safety system (PASS) provides the user with the ability to monitor movement through a motion sensor. When a user remains motionless for 30 seconds, the PASS device
goes into full alarm to alert those around the user. The PASS device also monitors cylinder pressure
and battery status.
The G1 SCBA consists of the following components:
G1 Facepiece
G1 Regulator (also referred to as Demand Valve)
G1 Heads-Up Display (HUD) (part of both facepiece and regulator)
G1 Pressure Reducer with low pressure warning device
G1 Control Module
G1 Power Module

Description
2.1
G1 Facepiece
The facepiece provides breathable air from the regulator past an inhalation valve to the inside of the
lens (to minimize lens fogging) and then through the check valves into the nosecup. Exhaled air is
directed out of the exhalation valve by the nosecup directly to ambient air. The face seal provides a
snug, comfortable fit, and tight seal. The facepiece is available in 3 sizes (small, medium, large) and
the nosecup is available in 3 sizes (small, medium, large).
The facepiece is equipped with a mechanical speech diaphragm that enhances speech communication. The HUD is provided inside the facepiece through light pipes from the regulator.
When in safe atmospheres with no regulator attached, ambient air can be inhaled directly through an
opening to facilitate breathing and speaking with minimal resistance.
Facepiece Versions
The facepiece is available with different head harnesses; fabric (both SpeeD-ON and 5-point) or
rubber (5-point).
US
G1
12
Description
2.2
G1 Regulator (also known as Demand Valve)
The mask mounted G1 Regulator is a pressure-demand regulator, which maintains a positive pressure in the facepiece while the SCBA is in use. The positive pressure regulator reduces the pressure
coming from the pressure reducer further to provide breathable air to the user.
The regulator is connected to the facepiece with a fixed position Push-To-Connect (PTC) connection.
The regulator has two cover options available, purge and solid cover. The purge cover allows users
to activate the regulator manually or provide a quick burst of air during use without using the bypass
knob.
The regulator houses an electronic module which provides HUD functionality and microphone placement. The microphones are activated when the regulator is connected to the facepiece and the user
begins breathing. Inhalation noise is not amplified by the system.
The hose for the regulator is available in two options, continuous or quick connect. The continuous
hose provides an uninterrupted connection from the pressure reducer to the regulator. A quick
connect coupling is positioned on the chest between the pressure reducer and regulator to enable
regulator removal from the SCBA for testing or repair. Both types of hoses for electronic versions have
integrated wiring and hoses.
2.3
G1 Heads-Up Display (HUD)
The HUD is integrated into the regulator and projects light into the facepiece. The HUD allows users
to see the cylinder pressure and alarm status while wearing the SCBA. The HUD receives the information on the SCBA and power from the power module. The HUD consists of 7 LEDs which are separated on the left and right sides to improve visibility and clarity. A light sensor in the regulator varies
the LED intensity depending on the ambient light condition (optional setting).
G1
US
13
Description
2.4
Cylinder and Valve Assembly
The cylinder and valve assembly store high pressure air which will be reduced to provide the user
breathable air. Cylinders are available in multiple pressures and rated service times. The valve
assembly provides the user the ability to open the pressure to the rest of the system. The valve
assembly consist of a handwheel for opening and closing the valve, pressure gauge that always
provides the pressure in the cylinder, threaded CGA connection for filling and attachment, and burst
disc for over pressurization.
The SCBA can be attached to the cylinder in multiple configurations. A threaded or quick connection
is available and a threaded cylinder can easily be upgraded to a quick connect attachment. The
cylinder can be connected to the SCBA by a side connection off the cylinder valve (remote connect).
When using a remote connect cylinder, a dove tail interlocking feature is used to secure the cylinder
to the backplate of the SCBA.

G1 Pressure Reducer with Primary Low Pressure Warning Device
US
The pressure reducer reduces the cylinder pressure to an intermediate pressure, which is in turn
further reduced by the regulator to a pressure that is respirable by the user. The pressure reducer
incorporates a fail safe design which ensures air flow to the user in the event of a malfunction within
the pressure reducer.
The pressure reducer incorporates an intermediate pressure relief valve, and a cylinder connector
with a sintered filter to capture particulates that may be in the air stream.
Universal Air Connection (UAC)
All NFPA approved SCBA are equipped with a UAC fitting (Universal Rescue Connection). The UAC
fitting is a male fitting inlet for use by Rapid Intervention Teams for emergency filling of the SCBA or
during transfill operations.
G1
14
Description
Primary Low Pressure Warning Device (Bell)
The primary low pressure warning device alarms when there is approximately 35 % of the SCBA’s
rated service time remaining and when the cylinder valve is first opened, providing an audible indication that the alarm is working properly. NIOSH regulation states that the primary low pressure warning
device must alert the user at 35%  2%. MSA sets all low pressure warning signals to the mean of
the requirement, hence 35 %.

G1 PASS Device
The PASS device on the G1 SCBA is made up of three components: battery module, power module,
and control module. The PASS device provides the user the ability to monitor movement through a
motion sensor. When a user remains motionless for 30 seconds, the PASS device goes into full alarm
to alert those around the user. The PASS device also monitors cylinder pressure and battery status.
G1 Control Module
US
The G1 control module is the user’s interface with the SCBA and PASS device.
The control module is assembled to the high pressure air source and to the power module by a pneumatics and electronic hose assembly. It is equipped with an analog gauge as well as a graphical
display to provide vital information: numeric cylinder pressure, battery status, alarms and time
remaining (optional).
G1
15
Description
When the control module is being read by the user, no buddy lights on the control module will flash
and a white gauge light will illuminate, to enable the user to read the gauge and display. If the SCBA
is equipped with the optional telemetry module, the radio link status and evacuation alarms are
displayed. The integrated PASS motion sensor is housed within the control module. The ALARM
button of the control module activates the full PASS alarm with or without air pressure.
G1 Power Module
The power module serves as the power supply and provides all of the information for the control
module, regulator and speaker module.
The power module is connected to the backplate. It connects to the battery module, emits audible
PASS alarms and pre-alarms and has 4 buddy lights.
The battery module is equipped with six C-cell batteries. The system notifies the user when the
batteries need to be replaced by emitting an audible tone from the power module, displaying an empty
battery icon on the display of the control module, and by a flashing yellow LED on the HUD.
The power module is also equipped with a RIT light, which activates when low pressure alarm (configurable to medium pressure alarm) occurs, to make it easier to see the UAC in the dark.
The power module has a data logging feature that records information about the SCBA while the
control module is turned on. This data log memory can be accessed using the MSA A2 Software.
The power module contains an internal real time clock. This clock can be reset using the
MSA A2 Software. By default, the internal clock is set to Eastern Standard Time.

G1 Harness and Carrier Assembly
The harness and carrier assembly consists of:
Backplate (houses the power module, battery module, and pressure reducer)
Cylinder band with latch to hold the cylinder
Shoulder pads
Adjustable pull straps
Lumbar pad
Waist belt
Regulator Keeper
Chest strap (optional)
Shoulder Straps
The shoulder pads are available in two options; standard and serviceable. The standard shoulder
pads provide weight distribution across the shoulder, friction pad to prevent slippage of the straps,
increased visibility with retroreflection material, and steel buckles for a secure fit. The serviceable
shoulder pads provide the same features as the standard shoulder pad but allow the user to easily
access the hoses without having to disconnect them from the SCBA. The tunnels on these pads are
released using snap buttons to ease in swapping or repair of components. The inside and outside of
the shoulder straps are identifiable by print/stitching. A facepiece clip can also be attached to either
shoulder strap.
The control module, regulator, and speaker module can be positioned either on the left or right
shoulder pad. Typically the regulator and speaker module are placed on the left shoulder and the
control module is placed on the right shoulder. The regulator keeper can be positioned in multiple locations including the waist belt and chest strap.The regulator and the regulator keeper must be on the
same side of the user.
Lumbar Pad
The lumbar pad is available in three versions:
Adjustable Lumbar Pad - The adjustable lumbar pad provides the user three positions for ideal
comfort. The lumbar pad can be adjusted by one-hand and can be adjusted while worn. The
lumbar pad also has a swivel feature to allow it to move with the user.
Fixed Position Lumbar Pad - The fixed position lumbar pad provides the user with the middle position of the adjustable lumbar pad position and is not adjustable. The lumbar pad also has a swivel
feature to allow it to move with the user.
Basic Lumbar Pad - The basic lumbar pad is a fixed position, non-swivel unit that provides a low
profile, light weight lumbar option for the user.

Optional Components
ExtendAire II
he ExtendAire II is a pneumatic manifold that allows two users to connect and share intermediate
pressure air. Each manifold contains both a male and female Quick Connect for ease of connection.
The manifold is attached to three feet of usable hose. A pouch is attached to the user’s left side to
store and protect the manifold and hose assembly.
Quick-Fill Pouch
The Quick-Fill Pouch is a storage pouch attached to the user’s right side. It is similar to the ExtendAire
II pouch, but is used to hold a Quick-Fill line. The pouch is held securely closed by a combination of
hook and loop fasteners and snaps, but can be opened using one hand.
Telemetry Module
The telemetry module provides the firefighter with two-way communication with Incident Command.
The firefighter's vital statistics such as cylinder pressure, approximate service time remaining, PASS
alarm, low battery alarm, and thermal alarm are transmitted back to Incident Command. Also, the firefighter has the ability to be evacuated remotely by Incident Command. The radio transmitter is located
inside of the power module. The telemetry module is only available for SCBAs with integrated PASS
devices. For details see Chapter 18.

Size Selection
Size Selection
Regardless of facial dimensions and respirator sizing charts, an actual respirator fit test, either qualitative or quantitative must be performed to ensure the correct respirator size selection.
(1)
Fit test the respirator size relative to your facial features and dimensions. The safety administrator or program manager might assist in selecting the initial size to try.
(2)
Carefully don the mask and conduct a negative pressure seal test. See donning instructions for
procedure.
(3)
If the facepiece does not pass the negative pressure seal test or feels uncomfortable, try the next
nearest size relative to your face.
Passing the negative pressure seal test does not verify the size is correct. The size selected must be
verified by successfully passing a Respirator Fit Test, either qualitative or quantitative. If the respirator
passes a negative pressure seal test but DOES NOT pass a Respirator Fit Test, try the next nearest
size.
Once the proper size is selected, the respirator must pass a negative pressure seal test every time
the facepiece is donned to ensure proper fit before using the respirator.
If other than facial seal leakage is detected, the condition must be investigated and corrected before
another test is made.
The facepiece must also pass the negative pressure seal test before the user attempts to enter a toxic
atmosphere.
The facepiece will not furnish protection unless all inhaled air is drawn through the SCBA.

Respirator Fit Test
WARNING
The user must perform a respirator fit test (Quantitative Test or Qualitative Test) and follow all warnings and limitations specified. Failure to do so can result in serious personal injury or death.
A qualitative or quantitative respirator fit test must be carried out routinely for each wearer of this respirator to determine or confirm the amount of protection that the respirator provides.
Quantitative Test
If a quantitative fit test is used, a fit factor of at least 500, based on ambient aerosol fit test methods
or equivalent, is required before any type of respirator is assigned to an individual.
Qualitative Test
If a qualitative fit test is used, only validated protocols are acceptable. The individual must pass a test
designed to assess a fit factor of at least 500.
NOTE: When this facepiece is used for CBRN APR, a fit factor of at least 2000 is required for quantitative or qualitative test. Refer to User Instructions (P/N 10158743) for more information regarding
CBRN APR use.
Use Quik Chek Kit (P/N 805078) to perform fit testing and following instructions provided with the kit.
The fit test kit includes an adapter and instructions. Canister sold separately. Be sure the probe does
not contact the face during fit testing. Failure to do so can result in false protection factor readings.
