A two-door, ultraviolet (UV) or germicidal lamp pass-through cabinet and control system were developed for use in an Anthonomus grandis Boheman mass-rearing facility. The unit allows passage of materials between rooms, or between rooms and the outside, with better contamination control than is possible by using ordinary doorway passages. Tests showed that microbial organisms which were suspended in air or spread in thin layers on filter paper were destroyed when exposed to the radiation produced by the lamps in the unit. The control system was designed and installed so that only one door of the cabinet could be opened at one time. When either door was opened and then closed, both doors were locked and the UV lamps were activated and remained on for a preset length of time before either door could be opened. The UV lamps could not be operative when either door was open. Lamp fixtures were mounted in the cabinet so that any packages or containers placed in the cabinet were surrounded by germicidal lamp rays.
