1. A method of sterilizing a closed environment comprising:
- (a) generating gaseous ozone into said closed environment to a predetermined ozone concentration;
(b) after reaching said predetermined zone concentration, rapidly increasing the humidity of said closed environment to a predetermined relative humidity level of greater than 80%;
(c) after reaching said predetermined relative humidity level, depleting said ozone;
(d) when said ozone concentration is reduced to a predetermined safe level, signalling.

Abstract
A method of sterilizing a closed environment is provided in which an disinfection apparatus is placed into the closed environment; it then generates ozone to a predetermined ozone concentration, following which the humidity of the closed environment is rapidly increased. A catalytic converter then reduces the ozone concentration to safe levels. When the ozone concentration is reduced to a predetermined safe level, the disinfection apparatus signals.
