4.     Notes on operation and storage.


Operation and keeping of the mask is to be performed according to the operating manual on the oxygen set POISK RUGI. RE.

Unlike previous models (Himalayas line of masks) mask POISK does not include latex and silicon, so it does not cause irritation and skin allergic reactions even within long-term use. Because of the wide inhale valve breathe resistance is reduced, it decreases the sensation of weariness, and curved shape of the chin part of the mask makes derivation of sweat from a face easier.

Exterior of the mask and its spare parts for the standard completion is represented on fig. 1.




1 – face part of mask (thermoplastic elastomer with no smell) is available in 3 sizes: S, M, L.

2 – elastomeric soft angle connector 22F 1705 connects inhalation valve and straight connector with jointed socket 6 mm;

3 - straight connector with  jointed socket 6 mm serves as coupling for a bag and a hose of oxygen supply to angle connector;

4 - flow indicator gives visual control of oxygen supply into the mask;

5 – breathing bag 801MM, capacity 0.5 litres serves for mixture of exhaled air and for the air fed from the hose;

6 – bayonet connector for attaching the hose to the oxygen reducer;

7 – controllable  elastic 4-pointed headband with an inhalation valve cap (POM-polyacetates) includes polyester-sulfones straps for head and neck;

8 - exhalation valve is made of  liquid silicone;

9 - inhalation valve is made of rubber based on ethylene, propylene and diene monomer;

10 – case with slots for valves (PA66 - polyamide).


Use only original details from the manufacturer. After/before using check, clean and disinfect the parts. Valves' disks need changing at least once a year.


    Air-tightness test: can be done two ways:

1) Close the exhale canal with your hand and breathe out softly for making extra pressure – breathing bag is expected to swell a little. On the edge of compaction of the face part of the mask there shouldn’t be any leakage.

2) Close inhalation valve with your hand and breathe in to make mask stick to face. If there is a leakage of air in this kind of testing or any other, adjust head straps and try mask of another size.

  Cleaning: use warm water and soft detergent (neutral pH 6-8). Do not use solvents (e.g. turpentine, acetone), hot water or bleach (e.g. perborate, percarbonate).

     Storage: mask should be protected from direct sunlight, grease and oil. Mask should be kept in a dry, clean place. Mask's parts can be kept not more than 5 years at the temperature from – 10 C to +30 C at the humidity no more than RH 75%.

 Operation at low temperature. During operation of mask at low temperature it is necessary to take into account the following:

1.     Accumulation of frost on the exhale valve and the protective cap of the exhale valve. Frost can be removed mechanically by tapping the exhale valve cap on a solid object: e.g. a boot, the handle of a ski pole, etc. Don’t hit the cap with a stone or a hammer – plastic become fragile at low temperature.

2.    Accumulation of frost and moisture in the breathing bag. The bag should be carefully disconnected from the straight connector and replaced by a new one (delivered in the complete set). The used bag should be properly cleaned, disinfected, dried and prepared for future use.

3.      Be careful with the inhale valve – it may cause skin frostbite. If necessary interchange the inhale valve and the angle connector: disconnect the straight connector 3 from the angle connector 2, take away the case with slots for valves 10, unroll and put it back into  the face part. The angle connector should be turned into the right position. Caution! Coupling between  the angle connector and  the case with slots for the valves can not disassembled!

4.    Remember that mask is a personal kind of equipment. Do not use other people's masks that have already been used – they may be the source of serious viruses and bacterial diseases. Every time after usage clean and disinfect your mask including connectors and breathing bag properly. During the climbing you can do it with the wet sanitary napkin. You can find the mask in a non-assemble condition in fig.2.
