Abstract

The present invention relates generally to systems and methods of disinfecting and/or decontaminating articles, and more specifically to a system and method of efficiently disinfecting and/or decontaminating articles such as pieces of mail that may have been exposed to diverse biological and/or chemical contaminants.

Claims

1. A method of decontaminating articles containing greater than 20% moisture by weight within an apparatus that includes a housing defining at least one opening, and an enclosure in flow communication with the at least one opening, at least one door configured to cover the at least one opening, respectively, and a rotatable drum in the enclosure, the rotatable drum defining a cavity, wherein the housing includes a layer of amorphous magnesium silicate fiber, the method comprising:

placing the articles in a water-based solution including a disinfectant;

placing the articles into the cavity via the at least one opening;

confirming that the at least one door is closed;

rotating the drum;

heating the air in the cavity;

providing microwave energy to the cavity;

providing ultraviolet light to the cavity from a plurality of ultraviolet light emitting apparatuses;

placing a chemical in the cavity;

opening the at least one door;

removing the articles from the cavity via the at least one opening; and

creating an electronic copy of the articles.

2. The method of claim 1, further comprising placing the articles in a holder;

and

placing the holder in the drum.

3. The method of claim 2, further comprising connecting the holder to the drum such that the holder is fixedly disposed relative to the drum.

4. The method of claim 2, further comprising separating a first portion of the holder from a second portion of the holder;

placing the articles between the first portion and the second portion; and

connecting the first portion and the second portion such that the first portion is fixedly disposed relative to the second portion.

5. The method of claim 2, further comprising placing up to about one pound of articles in the holder;

and

placing the holder in the drum.

6. The method of claim 1, further comprising placing the articles in the cavity for about 50 minutes.

7. The method of claim 1, further comprising heating the air in the cavity to about 160°
