1. SAFETY REGULATIONS
1.1. Correct Use
This Self-contained Breathing Apparatus - referred to hereafter as SCBA - is self-
contained open-circuit compressed air apparatus operating independent of the
ambient air.
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 full-face mask
(Refer to Instruction Booklet Full-Face Mask). The exhalation air is released directly
into the ambient atmosphere.
It is imperative that this instruction booklet be read and observed when using the
product. In particular, the safety instructions, as well as the information for the use
and operation of the product, must be carefully read and observed.
Furthermore, the applicable national regulations applicable in the user’s country

2. THE SCBA ARRANGEMENTS
2.1. Schematic
The equipment consists of:
•A cylinder containing air under pressure
•A harness to mount the cylinders on the back of the person
•A respiratory system which has a means to reduce the pressure of air from the
cylinder and of supplying the wearer with air on demand
•A facemask attached to a demand valve which maintains a positive pressure
inside the mask at all times

2.2. Workings of the SCBA
2.2.1. The cylinders contain about 1240 litres of compressed air at 300 bar. This gives the
wearer around 30 minutes of air supply for full usage or about 20 minutes for working
conditions (person breathes heavily during work hence there is more consumption of air
and that is why the time is lesser).
2.2.2. The reducing valve reduces the pressure by about 4 bars which is further reduced by the
demand valve which is attached to the mask.
2.2.3. The demand valve is the one that supplies the air to the wearer when inhaling.
2.2.4. The exhalation valve releases the air from the facemask.
2.2.5. When the air left inside the apparatus will last about 10 minutes (50-55 bar pressure), a
warning whistle is sounded continuously till the cylinder gets emptied. The start of this
whistle is an indication for the wearer to move out of the space he’s in to fight fire or
whatever purpose it is used for.
2.2.6. The face mask is of soft moulded nature rubber and five adjustable head straps
and a neck strap. It has a foam filled or air cushion seal and a full vision visor.
For correct positioning of the mask, the straps should be tightened in the
sequence where the first two lower (chin) straps then the middle pair (cheek
straps) and finally the head strap is tightened. Care should be taken to not over
tighten them causing discomfort to the wearer. The mask is made of rubber and
plastic with a shatterproof visor. It has an exhalation port with a speech
diaphragm and a nose guard.
2.2.7. The wearer should have a good, clear field of vision through the visor.
2.2.8. A gauge is provided, clipped or attached to the harness that carries the cylinder
and it monitors the pressure within the cylinder. It is positioned to be visible to the
wearer.
2.2.9. Spare cylinders must be provided for each set of breathing apparatus.
2.2.10. In case that the facemask is dislodged in a toxic atmosphere, the wearer should
hold his breath and position the mask correctly. Any inlet of such toxic air can be
highly dangerous.

2.3. Air Consumption
Approximate consumption by a person is as follows:
Degrees of work
Air consumption
(litres/minute)
Duration of cylinder in
minutes (1200 litres
capacity in minutes)
Duration of cylinder in
minutes (1800 litres
capacity in minutes)
Resting
8-12
150-100
225-150
Light Work
12-20
100-60
150-90
Moderate Work
20-40
60-30
90-45
Heavy Work
40-60
30-20
45-30
Nominal Working Duration =
(Fully Charge Cylinder Capacity) –10
40
We subtract 10 as 10 minutes is when the alarm starts ringing and it is a safe
period which must be taken into account. So, a 1200 litres cylinder will last for
1200/40 = 30 minutes minus the 10 = 20 minutes.
Nervousness and excitement can cause an increased demand of oxygen and a
proportionate increase of respiration rate.

The reducer is mounted in the lower area of the back plate. It reduces pressure of
the high-pressure air from the cylinder to mid pressure at about 7 bar. The air is
delivered through medium pressure hose to demand valve, reduce the pressure
again and then used by the user. Turn the hand wheel and connect the cylinder
connector with the cylinder. Once the cylinder valve is opened, the user can view
the pressure indication from the pressure gauge as which is connected to the high-
pressure hose. A pressure alarm device is equipped in the reducer. When the
pressure of the cylinder is lowered to 55 ± 5 bar, it will give off audible alarm signal
≥ 90 dB. The alarm device will not be dependent on the ambient air when alarm
device gives an alarm, so the alarm device will not lose its function even if in high
humid atmosphere or under sprinkle water, or even in very low temperature. In
addition, the air consumed for the alarm device’s alarm is ≤ 5 L/min.
There is also a safety release valve, which is set to about 11 bar, in case there is
anything wrong and the medium pressure rises, the valve will be opened, release
the over pressure to guarantee the performance of the demand valve.
2.6. The Demand Valve
The demand valve is a lung governed demand valve for a compressed air breathing
apparatus. It is connected between compressed air supply and full-face mask and
controls the inhaled and exhaled air. The demand is not an independent breathing
apparatus. It must be used exclusively mounted on a full-face mask. The demand is
not suitable for underwater diving.

2. Exhaust Button
4. Operating Button
Don’t push operating button and exhaust button at the same time. Don’t press
down the red and black button during the use, because pushing both buttons
can disconnect the demand valve from the mask.
The outer housing of the demand valve is made of high strength engineering plastic
to endure possible collision. The demand valve must be used with full mask.
2.7. Medium Pressure Hose
The explosion pressure for medium pressure hose is not less than four times of the
reducer output pressure. Connection of the medium pressure hose with the demand

valve is flexible and swivelling, which can automatically fit head movement of the
operator.
2.8. High Pressure Hose
A high-pressure gauge is connected with the high-pressure hose. The pressure
gauge surface is luminescent, so the pressure display can be viewed clearly even
in the dark. Connection of the pressure gauge and the high-pressure hose is
swivelling and canturn in 360°, this makes easy for the operator to view the pressure
gauge at any position.
There is a small hole in the high-pressure hose, which is safety hole. In case there
is leak from the high-pressure hose, air will be released from the small safety hole,
thus to avoid the high-pressure hose from exploding.
3. USE
The device can be used only after fully maintained and tested. If malfunctions or
defects were found before using, do not use the device. Prevent the respirator
from sharp objects and prevent it from collision with any objects during the use.
The device shall be checked and repaired by MSA authorized service centre.
