Security and resilience — Hardened protective shelters — Part 2: Requirements for shelter protective equipment

Scope

This document describes the functional requirements and methods for verification of performance for protective equipment and systems necessary to guarantee a desired protection level of a hardened protective shelter.

It covers six functional categories of protective equipment needed in a hardened protective shelter:

– Blast protection;
– Gas tightness;
– Tightness of penetrations;
– Ground shock isolation;
– CBRN (Chemical, Biological, Radiological, Nuclear) protection and
– Carbon dioxide (CO2) removal and oxygen (O2) addition.

This document does not cover any other structural parts or auxiliary systems of a shelter, such as

– Shell (walls, roof and floor) of a shelter;
– Heating, ventilation and air conditioning systems;
– Safety and security systems (e.g. locks or fire extinguishing) and
– Other electrical or electronic systems (e.g. lighting and communication).

This document is intended for use by architects and engineers designing hardened protective shelters, industry producing the targeted equipment and procurement organisations in construction industry sourcing such equipment.
