In accordance with DBN B.2.2-5, protective or protective-sealed doors that are resistant to excessive shock wave pressure should be used in vaults. Also:
- The width of the opening of internal doors in the premises should be at least 0.9 m.

- shutters should have sufficient load-bearing capacity (including pivot mechanisms and locking structure) to withstand the load from the blast wave overpressure of at least 100 kPa;
- a reliable presser around the entire perimeter;
- use tempered, shockproof or laminated glass;
- the bottom of windows is recommended to be located at a distance of 1.8 m from the floor level.
