Collective protection - penetration of contaminated air into facilities

The review article deals with the current issue of collective protection, including collective protection against contamination. The hypothetical threats to the national territory of contamination from toxic industrial agents from high-risk plants (HR) and radioactive materials are presented. Collective protection against toxic industrial agents was characterized, on the basis of NATO documents. The issue of isolation (sealing) of collective protection facilities was discussed. The physical basis of the penetration of hazardous substances into objects as a function of pressure and temperature changes was presented, including ways to protect objects from the penetration of contaminated air.
