Abstract: There is provided a system for protection/isolation against infections or disease-bearing persons including an enclosure defining at least two chambers, an isolation chamber having at least one entering and exiting closable opening, at least one ambient air inlet and at least one air outlet connectable to a blower/filter, and an airlock chamber juxtaposed the opening having an access and egress closable aperture, means for forming under-pressure in the isolation chamber and airlock chamber, and at least one biological filter operationally connected to the means for forming under-pressure. A method for protecting/isolating against infection or disease-bearing persons, is also provided.

Abstract: There is provided an NBC protection and decontamination system, including an enclosure, an airlock, an airlock compartment, having a ceiling, and including a back-flow collector, an air filtration unit, a compartment inlet valve communicating with the air outlet of the enclosure, an exit valve being provided in the compartment and spaced apart from the compartment inlet valve, and an opening providing controllable passage between the enclosure and the airlock, and an opening providing controllable passage between the airlock and the outside, wherein the airlock compartment is swept by two different airflows, a first airflow originating in the enclosure and a second airflow produced by the filtration unit.
