System and method for protection against nuclear, biological and chemical (NBC) contamination

An NBC protection and decontamination system, comprising:

• a space delimited by an enclosure constituted of walls and surfaces, said enclosure having at least one clean air inlet port and at least one air outlet;
• a decontamination unit attached to a wall of said enclosure, said decontamination unit having at least one air inlet communicating with said air outlet from the enclosure and at least one air exhaust valve spaced apart from said air inlet;
• said decontamination unit further having normally closed access openings to the enclosed space and to the outside;
• the arrangement being such that clean air flow within the space inside said enclosure is directed from one wall to an opposite wall in which said air outlet is located and air inside said decontamination unit is directed substantially from one end of the unit to the other end, so as to produce laminar air flow through said enclosed space and said decontamination unit.
