4.1 Prerequisites for use
4.1.1 General information
– The protective clothing and head protection that also
needs to be worn during the incident has been clarified.
Dissipative protective clothing should be worn for use in
explosion-hazard areas.
– The leak and functional test on the closed-circuit breathing
apparatus showed no faults (see "Testing the closed-
circuit breathing apparatus", page 22).
– The requirements, as described in chapter 4.1.2 and
4.1.3, have been met.
4.1.2 Compressed oxygen cylinder
WARNING
Risk of fire!
Contact between high-pressure oxygen and oils, greases,
organic materials or similar contamination may cause a fire.
This can lead to serious physical injuries or death.
► Make sure connections are kept clean and free of dirt.
– The filling pressure of the compressed oxygen cylinder
should be no less than 180 bar in order to be able to
achieve the maximum period of use possible.
– The compressed oxygen cylinder may only be filled with
oxygen that meets the following quality requirements:
– Purity: ≥ 99.5 Vol% oxygen
– Water content: ≤ 0.05 mg/L oxygen
– Tasteless and odourless
– National regulations apply for the maximum
permissible contaminants, in Germany for example:
Inert gases (Ar and all other inert gases): 5000 ppm
Carbon monoxide (CO): 5 ppm
Carbon dioxide (CO
2): 300 ppm
Oil: ≤ 2.5 mg/m

4.1.3 CO2 absorber
Refill absorber
– The refill absorber was filled before use and within the last
6 months. The soda lime used must meet the
requirements specified in chapter 5.2.7.3.
– The expiration date of the CO
2 absorber has not yet
expired when scheduled to be used.
– As soon as the refill absorber is installed in the closed-
circuit breathing apparatus, the CO
2 absorber can be
stored for 6 months. The apparatus must have
successfully passed the leak test and be sealed with the
protective cap.
– The air-tight shrink-wrapped or installed CO
2 absorber
was not transported on a vehicle further than 750 km.
Disposable absorber
– The barrier bag is completely sealed and intact until the
disposable absorber is installed.
– The expiration date of the CO
2 absorber has not yet
expired when scheduled to be used.
– Once the disposable absorber is installed in the closed-
circuit breathing apparatus, the storage time of the CO
2
absorber is 6 months, even if the soda lime could be used
for a longer period, the breathing bag, breathing hose and
medium-pressure hose are connected and the connecting
piece is sealed with a protective cap.
– The air-tight shrink-wrapped or installed CO
2 absorber
was not transported on a vehicle further than 1500 km.
