Restrictions on the use of Personal Protective Equipment
The breathing apparatus supply a gas mixture for breathing for approximately 2 hours and isolates the

The use of the breathing apparatus is allowed only under the following conditions:
•
the user has passed special training and is allowed to work using the breathing apparatus according
to medical indications as established;
•
the oxygen cylinder is fully filled with oxygen (with a minimum degree of purification of 99.5 %
by volume);
•
the absorption cartridge is filled with an absorber;
•
the breathing apparatus is regularly serviced and checked in accordance with this Manual;
•
the user has no beard and the mask fits tightly to the skin of the face.
NOTE!
Actual NWD for a particular user may differ from the nominal NWD due to the impact of various factors.
The actual NWD may be affected by:
•
physical fitness of the user (increased oxygen consumption);
•
the nature of work performed (active oxygen consumption);
•
emotional state of the user (an anxious or excited user can consume more oxygen);
•
the condition of breathing apparatus (poorly serviced or badly adjusted breathing apparatuses may
have a leak);
•
improperly filled absorption cartridge;
•
cylinder pressure before use (if cylinder is not filled completely).
DANGER!
In some cases, the actual NWD of the breathing apparatus may be less than 2 hours. Users who are
unfit, stressed-out, with a large build, who work in difficult conditions, as well as uninformed users or
users who do not keep the breathing apparatus in a good condition, will spend oxygen much faster.
