Safety Regulations

M1 Modular SCBA System

1 Safety Regulations

1.1 Correct Use

The MSA M1 - 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 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 defi-

ciency.

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.

When fitted with twin cylinders, the breathing apparatus might exceed the weight limit specified in

EN 137:2006.

DANGER!

This device is a pure gas protection device. It is not suitable for underwater diving.

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.

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.

Safety Regulations

M1 Modular SCBA System

1.3 Safety and Precautionary Measures

• Approved for use at temperatures between -40 °C and +60 °C depending on facepiece certifi-

cation. For detailed information, see chapter 10.

• The device may be used in potentially explosive atmospheres according to the class stated in

chapter 10.1.

• 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 cover-

ings (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 atmo-

spheres 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 approve

1.4 Contact Information

In the event of a product concern, contact the local MSA authorized repair center or distributor,

they will provide the necessary information to MSA for issue resolution. To report any serious

concerns or to inquire about the products, go to MSAsafety.com for information on the local MSA

authorized repair center or distributor.

Only use breathable air quality in accordance with EN 12021 and other applicable

national regulations.

Description

M1 Modular SCBA System

2 Description

The M1 SCBA is a pressure-demand self-contained open circuit 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

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. The fixed pneumatic does not include an integrated medium pressure coupling to

easily disconnect the LGDV from the pressure reducer. The following overview shows all options

for the SingleLine and classic configuration:

Fig. 1 Overview of SingleLine configuration (left) and classic configuration (right)

Mirroring of displayed options is possible. A maximum of three medium pressure couplings is

allowed.

Description

M1 Modular SCBA System

The backplate consists of an anatomically 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.

2.1 Full Face Mask

The M1 SCBA can be used with the G1 Facepiece, 3S and Ultra Elite full face mask. For more

2.2 Pneumatics

2.2.1 Pressure Reducer

The pressure reducer reduces the cylinder pressure to medium pressure, which will be further

reduced by the LGDV to a pressure that is respirable by the user. The pressure reducer incorpo-

rates 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 a medium pressure relief valve, and a cylinder connector with

a sinter filter to capture particulates that may be in the air stream.

The pressure reducer is marked with a serial number, a material number, a QR code, the CE

marking and the month and year of manufacture (MM/YY).

For the non-electronic configuration, the pressure reducer can be connected to a manifold

containing a pressure gauge (showing the cylinder pressure), a warning whistle for low pressure

alarm and a connector for the LGDV (SL configuration). The pressure reducer can also be

connected to a high pressure hose with standard pressure gauge and a separate medium pres-

sure hose with LGDV (classic configuration). The warning whistle for low pressure alarm can be

directly connected at the pressure reducer or equipped with a hose to the upper end of the back-

plate.

For the electronic configuration, the pressure reducer is connected to the SingleLine SCOUT.

Fig. 5 Pressure reducer

Primary Low Pressure Warning Device

The primary low pressure warning device is an acoustic warning device (signal whistle). It triggers

a continuous warning signal when the cylinder pressure drops below 55 5 bar.

Depending on pneumatics, the low pressure warning device can be located at the M1 pressure

reducer next to the cylinder, connected to a hose on the upper back of the user (Fig. 6) or within

a SingleLine (SL) manifold (Fig. 7).
