Abstract
A modulator 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.
Claims1
A method of maintaining a toxic free area comprising:
- sealing said area from contaminants,
- providing a source of filtered pressurized air,
- pressurizing said area with pressurized air from said source at a pressure above atmospheric,
- allowing access to said area only through a contamination control area, and
- flowing air from said toxic free area to said contamination control area.
Dependencies are inferred from the claim text.
