Abstract: A system and a kit for microbial control within an enclosure comprising an electronic component are provided. The enclosure includes an access cover configured to move to enable access to an interior of the enclosure with the electronic component at least partially positioned within the interior of the enclosure. An oxidant generator is configured to generate an oxidizing agent in a gaseous state and distribute the oxidizing agent in the gaseous state within the interior of the enclosure. The oxidant generator may be positioned within the interior of the enclosure, or the oxidant generator may be in fluid communication with the interior of the enclosure. The oxidant generator may be an ozone generator, such as an ultraviolet (UV) light source or an electrical discharge source, and the oxidizing agent may be ozone. Alternatively, the oxidant generator may be a chlorine dioxide generator, and the oxidizing agent may be chlorine dioxide.
