A modular transportable collective protection system for the decontamination and containment of personnel in a toxic free area. A contamination containment area is provided through which personnel are decontaminated prior to entering the toxic free area. The migration of contaminants is prevented by causing a purge of clean filtered air from the toxic free area to the contamination control area and to the exterior environment. A blower and filter unit provides air to the toxic free area to maintain an over pressure therein, ensuring that all entry to the toxic free area is through a flow of clean air.

1. A transportable collective protection system comprising a plurality of sealed enclosures, a first sealed enclosure connected to a source of filtered air under pressure, a second sealed enclosure connected to the first sealed enclosure by a sealed connection, said second sealed enclosure having an entrance distal said first sealed enclosure, said sealed connection being adapted to permit the passage of personnel into said first sealed enclosure, and to permit air flow from said first to said second sealed enclosure, whereby contaminated personnel may enter said second sealed enclosure, be decontaminated in said second sealed enclosure before entering said first sealed enclosure, and vapor contamination of said first sealed enclosure is prevented, said first sealed enclosure being a toxic free area (TFA), and second sealed enclosure being a contamination containment area (CCA), each of said enclosures being formed of a resilient material formed of a multi-layer thermoplastic composite, comprising a woven layer of high density polyethylene, laminated to a barrier film, and coated on both sides with a film of low density polyethylene.
