Function
The device supplies the wearer with oxygen which is created from the chemical potassium hyperoxide
[KO
2
]. In an emergency, the container is opened and the respiratory 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 potassium 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 KO
2
canister warms up, as does the inhalation air, gradu-
ally. This is normal and indicates the correct operation of the device.
The end of oxygen supply is indicated by increase of the inhalation resistance.

Marking/Certification
The devices are classified according to EN 13794 and marked with the type [code letter] and nominal
duration [minutes]. The type, nominal duration and referenced standard are marked on the device.
The device is marked as follows:

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 taken from the ambient air and the
exhalation air is expelled outside.
The demonstration and training device is comparable in size, weight, external construction, 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.
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.
