Addition of shelters SN.
If your house does not have a special protective room, you can improvise by accommodating one of the basements under the shelter.
Vaults must be enclosed spaces with the possibility of hermetic insulation. Vaults should be equipped so that they can be used both in normal conditions and in emergency or catastrophic situations.
Vaults must provide protection
- From the falling debris of buildings,
- Against radioactive radiation,
- Against the threat of fire and chemicals.
The room should be suitable for a long stay.
Near the shelter, there should not be dangerous devices (for example, systems that can be associated with fire and explosion hazard, as well as systems in which toxic gases and vapors may form). Asylum should, if possible, be located in the corner of the building and not have external openings. The area should not be more than 30 m 2 . The basement windows should be walled up to the full thickness of the wall, the mines to fall asleep. In the houses of the private building should provide for the possibility of a break in the wall to a neighbor, the size of about 60 x 80 cm (rescue exit). The inner height of the shelter must be at least 1.95 m. There should be no combustible elements in the vicinity of the door and access to it. Chimneys should not pass through the shelter. Gas and heating pipes, other pipelines that can cause danger, should not, if possible, pass through shelters. If necessary, it is necessary to install a stop valve directly on the enclosing walls of the living quarters.
Qualified masonry and plastering of internal walls can be left. The ceiling of the shelter and the floors above should be at least 15 cm thick, including screeds. It must also be ensured that, in case of possible fire hazard, the fire load in the premises above the shelter will be low, and if there is a danger of radioactive contamination, the windows and doors in the neighboring rooms will be closed. External walls below ground level should have a minimum weight of 350 kg per m 2 , and walls above ground level of 1000 kg per m 2 .
If there are openings in the outer walls of the basements adjacent to the shelter, the weight of a square meter of the inner wall of the shelter must be at least 750 kg.
For the possibility of a long stay in the shelter and the cleaning of the polluted air, forced ventilation is necessary. This will ensure the filtration of outdoor air through the NBC filter system and protective ventilation. For this purpose we offer a gas cleaning system BS40.
Gas cleaning system BS40
Gas filters separate all known chemical and biological agents (OB) that appear in the form of gases, aerosols or suspended particles.
The task of the HEPA filter is to separate small solids, especially chemical and biological OM. A filter of activated carbon by absorption, chemisorption and catalytic oxidation removes even smaller molecules of toxic gases from the air.
