Abstract

An enclosure for housing people in the event of a serious air quality degradation is provided. A pressurized enclosure, either permanent or temporary, includes an air supply system for filtering and subsequently supplying clean air to the interior of the enclosure. The structure will be deployable and/or activated from a remote control station or from the protective structure itself. Life support elements are stored in the enclosure for use as needed.

Claims

1. An integrated protective system for protecting the population of a particular community from air-borne toxic agents comprising:

a plurality of community protection systems located at selected sites in said community;

each of said community systems assigned its own unique site identity code and having;

(a) an enclosed structure;

(b) a community radio receiver for receiving transmissions from said master transmitter,

(c) a community computer connected to said community receiver and programmed to recognize its identity code and generate an output signal in response to said command;

(d) a community air management system capable of pressurizing said structure to a pressure higher than the ambient pressure outside of said structure with air from which toxic agents have been removed; and

(e) a community interface between said community computer and said community air management system and capable of energizing the latter upon receipt of said signal from said community computer;

whereby said station can automatically energize the air management systems associated with selected ones of said plurality of community protection systems.

2. The invention according to claim 1 wherein each said air management system comprises:

a plurality of filter sets with each set including a particulate filter medium and a gaseous filter medium connected in series;

a separate blower associated with each of said filter sets and connected to discharge air under pressure through the associated filter set into said structure; and

an electric motor drivingly connected to each blower.

3. The invention according to claim 2 and further comprising:

a plurality of sensors, each sensor being associated with one blower and assigned a blower identity code;

said plurality of sensors being connected to said interface to provide an indication that the associated blower is functioning properly;

said computer being programmed to produce a blower operation signal associated with each blower identity code in response to the output from each of said plurality of sensors;

a community radio transmitter connected to said computer for transmitting said blower signals and the associated blower identity code; and

a master radio receiver located in said master control station for receiving said blower signals and associated blower identity codes;

whereby said master station can monitor the operation of each blower in every one of the air management systems.

4. The invention according to claim 3 and further comprising:

a master speaker and a master microphone connected respectively to said master radio receiver and transmitter;

a community system speaker and a community system microphone respectively connected to said structure receiver and transmitter, whereby voice communication between the master control station and the community protection systems may be maintained.

5. The invention according to claim 4, and further comprising:

a separate detector means mounted on the exterior of each structure and connected to said community interface for the associated structure;

said detector means being capable of detecting toxic agents in the atmosphere in the vicinity of the associated structure;

each community computer being programmed to produce a detector signal associated with the site identity code for the associated structure;

each community transmitter being connected to the community computer in the associated structure to transmit the detector signal and the site identity code for the associated structure; and

a master computer in said master control station connected to said master radio receiver to receive the transmissions from all of said community transmitters.

6. The invention according to claim 5, and further comprising

a monitor connected to display the output from said master computer;

data storage means connected to said master computer for storing data regarding the geography of the community, the location of each structure and data received by said master radio receiver;

program means associated with said master computer and capable of displaying on said monitor a map of the community with the location of each structure shown thereon and indications of status at each structure.

7. The invention according to claim 1 wherein said particular community has a municipal water system and said structure has a plumbing system for distribution of water therein, and further comprising:

a tank for holding potable water; and

valve means having an activated position in which said plumbing system is isolated from said municipal water system while permitting communication between the latter and said tank, whereby the structure will have an available supply of potable water free from toxic agents.

8. The invention according to claim 7 wherein said valve means is moved to said activated position in response to receipt by said computer of said energizing command.

9. The invention according to claim 8 wherein said tank includes means for precluding the ingress of toxic agents into said tank while permitting water in said tank to flow freely into said plumbing system.

10. The invention according to claim 9, wherein said means for precluding comprises a vent pipe communicating between said tank and the interior of said structure so that only air from which toxic agents have been removed is pulled into said tank as water is drained out.

11. The invention according to claim 10, wherein each structure further comprises:

an air lock through which individuals may enter the structure;

shower means connected to said tank and located within said air lock for neutralizing toxic agents to which the individuals may have been exposed prior to entry; and

collection means for collecting and storing the waste water from said shower means to prevent the spread of toxic agents through the community sewer system.

12. The invention according to claim 1, and further comprising:

a building;

an enclosed space within said building;

a building command center in said space assigned its own center identity code and having;

(a) a center radio receiver for receiving transmissions from said master transmitter;

(b) a center computer connected to said center receiver and programmed to recognize its own center identify code and generate an output signal in response to said command;

(d) a center air management system capable of pressurizing said space to a pressure higher than the ambient pressure outside of said space with air from which toxic agents have been removed; and

(e) a center interface between said center computer and said center air management system and capable of energizing the latter upon receipt of said signal from said computer;

whereby said station can automatically energize said center air management system.

13. The invention according to claim 12, further comprising:

a plurality of building protection systems installed inside of said building, each of said building systems assigned its own building identity code and having;

(a) an enclosed tent collapsible to a stowed position and deployable to a shelter position; and

(b) a tent air management system capable of pressurizing said tent to a pressure higher than the ambient pressure outside of said tent with air from which toxic agents have been removed and in doing so urging said tent to assume said shelter position;

said center computer being programmed to recognize the building identity codes associated with each building protection system within said building and generate an associated output signal; and

said center interface also connected between said center computer and each of said tent air management systems and capable of energizing the latter in response receipt of said associated output signal.

14. The invention according to claim 1, and further comprising:

an enclosed wheeled vehicle moveable to a selected location and having sealable entry and exit doors;

means for decontaminating individuals entering through said entry door;

a vehicle air management system for supplying the interior of said vehicle with air under pressure free from toxic agents; and

a control room in said vehicle and having a vehicle radio transceiver for communication with said master control station;
