Entrances used in peacetime and equipped with protective and gastight doors should be filled with doors taking into account the requirements of building and construction design standards and fire safety standards. This means that if a protective and hermetic door is installed in the doorway (provided by the project), but there is a need for a fire door, a separate fire door should be installed (provided by the project) next to the fire door. It will be a mistake to try to make the ZD fireproof, because this will lead, firstly, to an increase in its cost by two or three times, and secondly, to an increase in its overall dimensions.
