Modifications
A fairly widespread version is the GDZK-U kit.
Supports protection against gaseous toxins generated by the combustion of various substances. You can also insure yourself against:
- organic poisons boiling at temperatures over 65 degrees;
- inorganic toxins (chlorine and hydrogen sulfide);
- acidic synthesized poisons (sulfur dioxide and hydrogen fluoride);
- chemical warfare agents such as phosgene and cyanogen chloride;
- ammonia;
- carbon monoxide;
- toxic nitrogen oxides;
- dust suspensions;
- smoke and fog.
You can also use the device GDZK-EN. This protective modification will help save not only the respiratory system and eyes, but also the scalp and neck. The product differs from the previous version in that it is designed for children aged 10 years. Likewise, use is guaranteed by people with beards and long hair. The only negative property is disposable character. However, this is a generic feature of all such models.
Device and application
The professional self-rescuer GDZK (or gas and smoke protection kit) is designed to cover the respiratory tract and eyes during evacuation from fires. The device can be used in private houses, high-rise buildings, industrial enterprises, the subway system and other underground communications. In addition to protecting against fire, GDZK is allowed to be used to eliminate the consequences of industrial accidents with the release of toxic substances.
The manufacturer of the GDZK is the Pozhbezopasnost-Yug company. The fire-resistant hood is connected to a filter-absorbing box and valves responsible for inhalation and exhalation. The glass is dimensioned to guarantee maximum visibility.
The design is designed for use:
- adults and adolescents from 12 years old;
- glasses wearers;
- people with long hair, mustaches and beards.
Specifications
The gas and smoke protection kit fully lives up to its name. Even in direct contact with an open flame, durability is guaranteed for at least 5 seconds. But provided that the temperature does not exceed 850 degrees. At the same time, protection against toxic combustion products and harmful substances, even heated to high temperatures, is maintained. If the GDZK self-rescuer is exposed to temperatures up to 200 degrees, then it will retain its protective capabilities for 50 seconds.
Successful isolation of the human body from corrosive smoke and other substances that pose a threat to life and health in a fire is guaranteed. Among other things, exposure is prevented:
- ammonia;
- organic fluorine compounds;
- hydrogen chloride;
- pure chlorine;
- benzene;
- a number of other toxic compounds.
The bottom of the mask is supplemented with a cuff of increased elasticity. It fits snugly to the body. The hood hides a rubber half mask, inside which the filter cartridge is fixed. This cartridge is supplemented with an air inlet valve. The presence of a negotiation system is provided. The headband is adjustable to individual sizes.
Useful properties are maintained in the entire temperature range from -30 to +50 degrees for ½ hour. Based on the results of testing, the following operating and protection times were declared:
- from carbon monoxide and hydrogen chloride - at least 30 minutes;
- from hydrogen cyanide and acrolein - 30 minutes;
- from cyanogen chloride (concentration 5 mg per 1 cubic meter) - 15 minutes;
- from hydrogen cyanide at a concentration of 0.44 mg per 1 cu. dm - 15 minutes;
- from organophosphorus toxic substances at a concentration of up to 0.05 mg per 1 cu. dm - also at least 15 minutes.
In addition, protection is guaranteed for 15 minutes at low concentrations:
- chlorine;
- hydrogen sulfide;
- sulfur dioxide;
- ammonia;
- isobutane;
- nitric oxide;
- mercury vapor.
Terms of use
A self-rescuer must be installed in any building above 5 floors. Such devices should be available in all hotel rooms, but it is useful to use them at home as well. If an extreme situation arises, you need to quickly (but carefully) remove the mask from the package. Hands are inserted into the inner cavity of the mask, and then stretched and put on the head.
It is imperative to check that the filtration unit is exactly opposite the nose. Hair needs to be tucked into the collar. They also check the tightness of the hood. If necessary, adjust the position of the mask using belts or an elastic band
It is important to remember that it is categorically impossible to stay in the room beyond the time allotted for safe evacuation. Any delay can be fatal
The device has a shelf life of 5 years. But it is guaranteed only with proper observance of storage standards. Only dry rooms are suitable for him, the temperature in which does not fall below 0 and does not rise above 30 degrees. If the mask is mechanically damaged, it cannot be used, it can only be disposed of. Otherwise, it is sufficient to follow the current manufacturer's instructions.
