SAFETY REGULATIONS MSA
4 BD 96 SL
GB
1. Safety Regulations
1.1. Correct Use
The MSA BD96 SL (referred to hereafter as compressed air breathing apparatus)
is a self-contained breathing apparatus operating independent of the ambient air.
Breathable air is supplied to the user from compressed air cylinder(s) via a
pressure reducer, a demand controlled dosage assembly (see Instruction Manual
for the Lung Governed Demand Valve) and a face piece (see Instruction Manual
for the Face piece). The exhalation air is released directly into the ambient
atmosphere.
It is imperative that this operating manual be read and observed when using the
compressed air breathing apparatus. In particular, the safety instructions, as well
as the information for the use and operation of the apparatus, must be carefully
read and observed. Furthermore, the national regulations applicable in the user's
country must be taken into account for a safe use.
Alternative use, or use outside this specification will be considered as non-
compliance. This also applies especially to unauthorised alterations to the
apparatus and to commissioning work that has not been carried out by MSA or
authorised persons.
Danger!
This product is supporting life and health. Inappropriate use, mainte-
nance or servicing may affect the function of the device and thereby
seriously compromise the user’s life.
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.
Danger!
This compressed air breathing apparatus is a pure gas protection
device. It is not suitable for underwater diving.
1.2. Liability information
MSA accepts no liability in cases where the product has been used
inappropriately or not as intended. The selection and use of the product are the
exclusive responsibility of the individual operator.
Product liability claims, warranties also as guarantees made by MSA with respect
to the product are voided, if it is not used, serviced or maintained in accordance
with the instructions in this manual.

2.1. Standard Model (BD 96 SL)
The carrying assembly consists of an anatomically designed backplate of
antistatic plastic with carrying slots for easy handling. On the lower part of the
carrying assembly are the supports for the pressure reducer and an elastic bump
protector. On the upper part of the assembly, a cylinder support is attached with
integrated line guide.
The carrying belts and the hip belt are adjustable in length.
One or two compressed air cylinders can be placed in the cylinder support. The
cylinder strap is freely adjustable and after inserting the compressed air
cylinder(s), it is tied down tightly and secured with the tension clamp.

3 Quick-Fill coupling (not for standard model)
4 Lead seal
The pressure reducer (see Fig. 2) is mounted in the lower area of the carrying
plate. On the pressure reducer, there is a safety valve and the multi-channel line
for connecting the combo pressure gauge. The pressure reducer reduces the
cylinder pressure to approx. 7 bar and the safety valve activates on non-permitted
pressure rise to prevent damage insuring the continued supply of breathable air.

4 Second connection
The combo pressure gauge (see Fig. 3) is connected at the end of the multi-
channel line. It consists of the pressure gauge (1) itself, the coupling for the lung
governed demand valve (2) as well as an acoustic warning device (3) (signal
whistle). It triggers a continuous warning signal when the cylinder pressure drops
below 55±5 bar. The second connection (4) connects a second lung governed
demand valve (e.g. backup set).

2.2. Model with Quick-Fill Coupling (BD 96 SL-Q)
Besides the standard unit fittings, this model also comes with a high pressure
safety coupling (see Pos. 3 in Fig. 2).It is then possible to fill 300 bar compressed
air cylinder(s) whilst the compressed air breathing apparatus is in use.
Warning!
In compressed air breathing apparatus with Quick-Fill couplings the use
of 200 bar compressed air cylinders is not permitted.

3. Using the Compressed Air Breathing Apparatus
Warning!
The compressed air breathing apparatus may only be put into use in a
fully maintained and tested condition. If malfunctions or defects are
noticed prior to use, do not use the compressed air breathing apparatus
under any circumstances.
Get the apparatus checked and repaired by an authorised service
centre.
3.1. Connecting one Compressed Air Cylinder
Fig. 4 Compressed air breathing apparatus with one compressed air cylinder
(1) Place compressed air breathing apparatus horizontally so that the back face
is uppermost (see Fig. 1).
(2) Bring cylinder separator (5) into a horizontal position opposite the tension
clamp (2) until it catches.
(3) Check gasket on pressure reducer (10) for proper condition.
(4) Open tension clamp on cylinder retaining strap (3) and extend strap
(see Fig. 7).
(5) Push compressed air cylinder through the cylinder strap (3) with the cylinder
valve toward the pressure reducer, so that it lies on the central support (4).
(6) Screw cylinder valve onto pressure reducer, if necessary, bring the
compressed air breathing apparatus with valve up into a vertical position.
(7) Fasten cylinder strap, do not over tighten.
(8) Check position of compressed air cylinder, retighten if necessary.

uppermost (see Fig. 1).
(2) Hinge cylinder separator (5) into a vertical position until it catches.
(3) If there is no T-piece connected to the pressure reducer (10), check gaskets
on pressure reducer and T-piece and screw in T-piece loosely.
(4) Open tension clamp on cylinder retaining strap (3) and extend strap
(see Fig. 7).
(5) Push one compressed air cylinder through the cylinder retaining strap so
that the cylinder valve points to the T-piece, and lies on one of the outer
supports.

With right-angled T-piece, align the compressed air cylinders by hinging
the pressure reducer and pulling the cylinders together (see Instruction
Manual for T-pieces).
(9) Tighten all three high pressure connection handwheels.
(10) Briefly open cylinder valves and check for escaping air, retighten if
necessary.

necessary.
3.3. Donning the Compressed Air Breathing Apparatus
(1) Check all components of the compressed air breathing apparatus for
defects and malfunctions.
(2) Don breathing apparatus with shoulder straps fully extended.
(3) Close hip belt and tighten loose ends.
(4) Tighten shoulder straps until the back plate fits comfortably.
(5) Adjust shoulder straps to achieve a comfortable weight distribution between
shoulder straps and hip belt.
(6) If required, connect lung governed demand valve to medium pressure
coupling (see Instruction Manual for Lung Governed Demand Valve).
3.4. Condensed Prior to Use Check
(1) Open cylinder valve(s) and check pressure on the combo pressure gauge.
The pressure values must read:
for 300 bar c
y
linders minimum 270 ba
r
for 200 bar c
y
linders minimum 180 ba
r
(2) Close cylinder valve(s) and observe pressure gauge.
•The pressure must not drop more than 10 bar in 60 s.
(3) Carefully activate flushing mode of the lung governed demand valve, closing
exit port as much as possible.
(4) Observe pressure gauge.
•The warning signal must sound at 55±5 bar.
