1 Safety Regulations
1.1 Correct Use
The M1 Modular SCBA System – referred to hereafter also as device – is a
pressure-demand self-contained breathing apparatus (SCBA) operating
independent of the ambient air for use in firefighting and/or in atmospheres
immediately dangerous to life or health.
In combination with a certified facepiece (full face mask) the device protects the
wearer against inhalation of hazardous substances and mixtures, harmful
biological agents and oxygen deficiency.
Breathable air according to EN 12021 is supplied to the user from a compressed
air cylinder via a pressure reducer, a lung governed demand valve and a
facepiece. The exhalation air is released directly into the ambient atmosphere.
DANGER!
This device is a pure gas protection device. It is not suitable for underwater diving.
Failure to follow this warning will result in serious personal injury or death.
WARNING!
Only trained individuals should be allowed to use the device after ensuring
sufficient knowledge on donning and general use of the device.
Failure to follow this warning can result in serious personal injury or death.
WARNING!
Read this manual carefully before using the device. The device will perform as
designed only if it is used and maintained in accordance with the manufacturer's
instructions. Otherwise, it could fail to perform as designed and persons who rely
on this device for their safety could sustain serious personal injury or death.
Before use the product operability must be verified. The product must not be used
if the function test is unsuccessful, it is damaged, a competent
servicing/maintenance has not been made, genuine MSA spare parts have not
been used.
Failure to follow these warnings can result in serious personal injury or
death.
1.2 Liability Information
MSA accepts no liability in cases where the device has been used inappropriately
or not as intended. The selection and use of the device are the exclusive
responsibility of the individual operator.
Product liability claims, warranties and guarantees made by MSA with respect to
the device are voided, if it is not used, serviced or maintained in accordance with
the instructions in this manual.
1.3 Safety and Precautionary Measures
• The device is approved beyond the specifications of EN 137:2006, for the
temperature range between -40 °C and +60 °C as type 2 device
(application for fire fighting). If the certification of the breathing connection
has a different (lower) temperature range, this must be taken into account
accordingly.
• The device may be used in potentially explosive atmospheres according
to the class stated in M1 Modular SCBA operating manual.
• The ATEX class of any other equipment used together with this device
has to be regarded as well. The lowest class sets the limit.
• If the device is used in an explosive atmosphere, dissipative clothes and
footwear must be used in conjunction with dissipative grounds. When
used in explosive atmospheres there must be direct contact between the
head harness of the mask and the head. Do not use head coverings
(e.g.fire hoods) under the head harness.
• Compatibility with other types of Personal Protective Equipment (PPE)
worn during use of the device (e. g. clothing and helmets) has to be
ensured according to Directive 89/656/EC.
• Use of the device in a vicinity that generates strong electrostatic charges
in explosive atmospheres is not allowed.
• Do not expose the device to any substances that will or might attack any
part of the SCBA, causing the SCBA to not perform as designed and
approved.
Only use breathable air quality in accordance with EN 12021 and
other applicable national regulations.
2 Description
Breathable air is supplied to the user from a compressed air cylinder via a pressure
reducer, a lung governed demand valve (LGDV) according to EN 137:2006 and a
full face mask according to EN 136:1998 (see operating manuals of lung governed
demand valve and full face mask). The exhalation air is released directly into the
ambient atmosphere.
The M1 SCBA can be configured via an ATO code with SingleLine, classic
pneumatic or fixed pneumatic (see M1 Modular SCBA System operating manual).
The following overview shows all options for the SingleLine and classic
configuration:

SCOUT)
The backplate consists of an ergonomically designed plate of antistatic plastic with
handles for easy transport of the apparatus. The pressure reducer is located in the
lower section of the backplate. On the upper part of the backplate, a cylinder
support is attached with integrated hose retainer. The shoulder straps and the hip
belt are adjustable in length.
One or two compressed air cylinders can be placed on the cylinder support. The
cylinder strap is adjustable and after inserting the compressed air cylinder(s), it is
tightened and secured using the cylinder buckle.
The structure of the compressed air breathing apparatus is based on a modular
design. This allows the user to configure the compressed air breathing apparatus
from the modules available to match his specific requirements.
The M1 SCBA can be used with the G1 Facepiece, 3S and Ultra Elite full face
mask. For more information, see relevant operating manual. The M1 SCBA can be
used with the following lung governed demand valves: M1-AE LGDV M45x3, M1-
AS LGDV, M1-ESA LGDV, M1-AS-B LGDV. For more information, see LGDV
operating manual.
3 Use
3.1 Visual Inspections
Conduct a visual inspection upon receipt.
WARNING!
• Do NOT examine the SCBA before it is decontaminated, cleaned, and
disinfected if there is a risk of exposure to hazardous contaminants. Obey
the applicable decontamination procedures, clean and disinfect the SCBA
first, then examine it.
• If the SCBA shows signs of internal moisture, damage, deterioration, or
any of the conditions listed in the Visual Inspections section, remove the
SCBA from service and return it to an MSA trained and certified repair
technician.
• Never substitute, modify, add, or omit parts. Use only exact replacement
parts in the configuration as specified by MSA.
Failure to follow these warnings can result in serious personal injury or
death.
WARNING!
If the SCBA shows any of the conditions listed in the Visual Inspections section,
remove the SCBA from service. Make sure an MSA trained and certified repair
technician corrects the unsatisfactory condition before returning the SCBA to
service.
Failure to follow this warning can result in serious personal injury or death.
WARNING!
Never substitute, modify, add, or omit parts. Use only exact replacement parts in
the configuration as specified by MSA.
Failure to follow this warning can result in serious personal injury or death.
All Components
1. Inspect all components for deterioration, dirt, moisture, cracks, debris,
tears, holes, stickiness, signs of heat or chemical related damage or other
visible signs of damage.
2. Inspect all straps (shoulder straps, pull straps, hip belt, waist straps, full
face mask head harness) for tears, cuts, wear, abrasion, missing buckles
or straps.
3. Perform all component specific inspections listed below.
Cylinder
1. Check the test date on the cylinder approval sticker located on the cylinder
neck or on the cylinder label.
a.
Make sure that the cylinder in use is approved as part of the MSA M1 SCBA
system and fulfills all requirements to be in operation according to the cylinder
manual and relevant national regulations.
3.2 Functional Tests

WARNING!
• Before entering the hazardous area, the device must be put on.
• Before entering the hazardous area, check the M1 electronic devices for
mechanical damage.
• If the SCBA does not function properly as described in this section, the
SCBA must be removed from service and must be checked and corrected
for proper operation by an MSA trained or certified repair person before
using.
• The full face mask may not seal properly with your face if you have a
beard, gross sideburns or similar physical characteristics. An improper
facial seal may allow contaminants to leak into the full face mask, reducing
or eliminating respiratory protection. Do not use this device if such
conditions exist.
• The full face mask seal must be checked before each use.
• A nosecup must be installed in the full face mask.
• In order to guarantee a proper fit for those wearing glasses, a spectacle kit
must be worn since ordinary glasses cannot be worn under the full face
mask.
• Never remove the full face mask except in a safe, non-hazardous, non-
toxic atmosphere.
• Users must wear suitable protective clothing and precautions must be
taken so that the device is not exposed to atmospheres that may be
harmful to it.
Failure to follow these warnings can result in serious personal injury or
death.
