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

What is claimed is:

1. A method for efficiently decontaminating discrete surfaces of military equipment while in the field, the method comprising:
applying a chemical warfare agent (CWA) indicator to a surface of military equipment;
chemically reacting the CWA indicator with a CWA associated with a discrete portion of the surface of the military equipment to provide an observable or machine readable response in commensurate scope with the discrete portion of the contamination; and
precisely decontaminating the discrete portion of the surface of the military equipment using decontaminant without exposing other surface portions exhibiting no response to the decontaminant.

2. The method of claim 1 wherein said indicator is an aqueous based sensor.

3. The method of claim 1 wherein said response is read by a machine.

4. The method of claim 1 wherein said response is colorimetric.

5. The method of claim 1 further comprising ceasing the decontamination when no readable response is observed.

6. The method of claim 1 further comprising:
using a machine to read the response;
sending the reading to a computer;
providing a computer analysis of the reading where said computer determines a location of the discrete portion of the surface of the military equipment associated with the contaminant;
transmitting said analysis to a decontaminating process unit; and
if a response is present, applying further decontamination; and
if no response is present, the decontamination method is determined to be effective.

7. The method of claim 6 further comprising using at least one robotic arm to apply the indicator.

8. The method of claim 6 wherein said decontamination processing unit comprises:
at least one robotic spray arm; and
one or more robotic scrubbing arms in communication with said robotic spray arm.

9. The method of claim 1 further comprising using automated processes to perform the method.
