Abstract : Sealing protective structures against chemical agents is an issue of primary concern. Without chemical protection, the integrity of protective structures may not be complete. Although structural elements, such as concrete walls, blast doors, blast valves, and revetments, afford protection against shock, blast, and fragmentation, they cannot provide the required protection against chemical agents. Proper pressurization and sealing of the living area within a protective structure must be ensured. This section addresses the different types of seals which may already exist, or which may possibly be used in future structures. It includes various information on these seals, including sealing materials, seal application, and current and previous seal designs. Each type of seal is examined individually. Guidelines, which can help in the design of seals for protective structures and minimize the risk of exposure to chemical agents, are provided
