Abstract
A germicidal irradiation approach to killing germs on conveyors and other check out surfaces in stores, such as grocery stores, which sell articles such as food items where possible contamination from leaks and the like is a concern. An adaptable, portable ultraviolet light apparatus is provided to irradiate surfaces such as conveyor belts.
Claims10
A portable ultraviolet (UV) germicidal irradiation method comprising:
- mounting a portable germicidal irradiation system to a checkout surface to be irradiated utilizing a releasable attachment mechanism;
- irradiating the checkout surface with a source of UV germicidal irradiation;
- supporting and shielding the source with a housing;
- utilizing a conveyor belt motion control detector to detect conveyor belt motion;
- and
- controlling the timing of turning on and off the source by a processor whereby the source is turned on when conveyor belt motion is detected and the source is turned off when conveyor belt motion is not detected.
