DescriptionMSA
SSR 90 [K60]
GB 7
The device includes a chemical canister with potassium hyperoxide [KO2], which is
required for the regeneration of the exhaled air.
After starting 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.
The device is carried by a carrying strap over the shoulder.
The device is equipped with a starter for the initiation of use which is actuated when
the device is put on. The breathing bag then fills with oxygen. During the escape,
the breathing air prepared in the KO2canister is made available in the breathing
bag.
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.
After actuating the starter, the breathing bag immediately fills with oxygen and
breathing can begin.
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.

2.4 Demonstration and Training Device
The demonstration and training device can be used for demonstration and practise
of wearing and breathing without using a chemical canister. The inhalation air is tak-
en from the ambient air and the exhalation air is expelled outside.
The demonstration and training device is comparable in size, weight, external con-
struction, handling and breathing resistance to the emergency use devices.
To distinguish it from the emergency use devices, the demonstration and training
device has marked blue.

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 [Æchapter 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.
