1. A closed loop vapor decontamination system for decontaminating a defined region, said system comprising:

  • a chamber defining a region;

    a first fluid flow path connected at both ends to said chamber to define a first closed loop path through said chamber;

    a second fluid flow path connected at both ends to said chamber to define a second closed loop path through said chamber;

    a means for conveying a carrier gas simultaneously along said first and said second fluid flow paths;

    a generator for generating vaporized hydrogen peroxide disposed along said first fluid flow path for introducing vaporized hydrogen peroxide into said carrier gas as it circulates through said first fluid flow path;

    a destroyer for converting said vaporized hydrogen peroxide into water and oxygen disposed along said second fluid flow path for breaking down said vaporized hydrogen peroxide in said carrier gas as it circulates through said second fluid flow path; and

    a controller controlling the amount of said carrier gas flowing along said first and second fluid flow paths.
