Abstract

A method for efficiently decontaminating surfaces is provided comprising applying an indicator to a surface wherein the indicator provides an observable or machine readable response when a contamination is present on the surface, wherein the response is located relative to a location of the contamination; and decontaminating the location of the contamination, and optionally rechecking the location of the initial contamination post decontamination to ensure that the surface is free of contamination.

First claim

The invention claimed is:

1. A method for removing chemical warfare agents (CWA) from potentially CWA contaminated surfaces, the method comprising:
applying a CWA indicator to a surface;
chemically reacting the CWA indicator with a CWA associated with one or more discrete portions of the surface to provide an observable or machine readable response in commensurate scope with the discrete portions of a CWA contamination; and
selectively decontaminating the discrete portions of the surface using decontaminant.

2. The method of claim 1 , wherein the surface is a surface of equipment.

3. The method of claim 2 , wherein the equipment is personal protective equipment.

4. The method of claim 2 , wherein the equipment is emergency response equipment.

5. The method of claim 2 , wherein the CWA indicator is applied to a section of the surface of the equipment.

6. The method of claim 1 , wherein the CWA indicator is aqueous based.

7. The method of claim 1 , wherein the response is at least one of a colorimetric change, a temperature change, a thickening, a thinning, a fluorescence change, an absorption change, an infrared intensity or wavelength change, and/or an ultraviolet intensity or wavelength change.

8. The method of claim 1 , wherein the response is machine readable.

9. The method of claim 8 , further comprising sending the machine readable response to a computer.

10. The method of claim 9 , further comprising providing a computer analysis of the reading.

11. The method of claim 10 , wherein the computer analysis comprises determining a location of the response.

12. The method of claim 10 , further comprising transmitting said analysis to a decontaminating process unit.

13. The method of claim 12 , wherein the selectively decontaminating comprises using the decontaminating process unit to decontaminate the discrete portions, wherein the selectively decontaminating is an automatic process comprising applying a decontaminating solution to the discrete portions, scrubbing the discrete portions, and rinsing the discrete portions.

14. The method of claim 1 , further comprising using at least one robotic arm to apply the CWA indicator.

15. The method of claim 1 , wherein the surface is a surface of at least one of a floor, a wall, a ceiling, a vehicle, a glove, a protective suit, an article of clothing, skin, a window, a door, a shelf, a table, a counter, a computer, a tank, a helicopter, a plane, a motorcycle, a bicycle, glassware, glasses, a helmet, a paper, a weapon, vegetation, soil, carpet, and/or military equipment.

16. The method of claim 1 , wherein the CWA indicator is enzyme based.

17. The method of claim 1 , wherein the response is machine readable by one more of a Raman detector, a camera, a spectrometer, a thermal camera, a Joint Chemical Agent Detector (JCAD), an improved Chemical Agent Monitor (ICAM), an Avalon standoff Raman spectrometer, a hyperspectral imager, an identiFINDER instrument, and/or a night vision device.

18. The method of claim 1 , wherein the CWA indicator is a first CWA indicator, the method further comprising applying a second CWA indicator following the decontaminating to determine whether the decontaminating was successful.

19. The method of claim 18 , wherein the second CWA indicator is a different indicator from the first CWA indicator.

20. The method of claim 1 , further comprising ceasing the decontaminating when no readable response is present.
