DescriptionMSA
SavOx / SavOx Industry
GB 7
After starting the device by pulling out the breathing tube the device it is directly
ready for use. During the escape, the device supplies the wearer with breathable
air which is prepared in the KO2canister.
Normally the SavOx is carried at the belt. The SavOx Industry is carried over the
shoulder. Both devices can be stored on vehicles.
2.2 Function
The device supplies the wearer with oxygen which is created from the chemical po-
tassium hyperoxide [KO2]. In an emergency, the container is opened and the res-
piratory protection device is taken out.
The device has a closed breathing circuit. When in operation, the exhaled air is
transferred into the chemical canister with the potassium hyperoxide. The potassi-
um hyperoxide reacts with the humidity and the carbon dioxide of the exhaled air
and, at the same time, creates oxygen and heat. The air for inhalation prepared in
this way is fed into the breathing bag and is then inhaled again.
The amount of resulting oxygen depends on the intensity of respiration. Increased
respiration [more carbon dioxide, more humidity] increases the formation of oxygen
or vice versa.
When the device is used for breathing, the KO2canister warms up, as does the in-
halation air, gradually. This is normal and indicates the correct operation of the de-
vice.
The end of oxygen supply is indicated by increase of the inhalation resistance.
The device is equipped with a starter which starts automatically when the breathing
tube is pulled. After starting it fills additional oxygen into the breathing bag.
Warning!
The device must only be opened for use!
Otherwise humidity from the ambient air can penetrate the open device
and affect the performance.
Used or opened devices must be replaced by new devices.

4.3 Tightness Test
The tightness test of the device is carried out using the MSA tightness tester for
chemical oxygen breathing protection apparatus. Detailed descriptions of the struc-
ture, function, use and maintenance of the tightness tester can be taken from the
relevant operating manual of the tightness tester [chapter 8].
The tightness test of the device is carried out as follows:
(1) Push the device without any straps into the tightness tester in such a way that
the cover points towards the door.
(2) Close the door and lock.
(3) Set timer to 90 s.
(4) Create overpressure with the lever, i.e. push the lever downwards until it
engages and start the timer at the same time.
(5) After 30 seconds, cover the black pointer with the red pointer.
(6) After a further 60 seconds, the timer signals the end of the test period. Then
read the pressure difference between the red and the black pointers.
The device is tight if the black pointer remains in the prescribed pressure range and
if the pressure difference is no more than 5 mbar.
If the pressure drop is more than 5 mbar, the unit must be replaced.
