Abstract
A pass box configured to accommodate and decontaminate an article by concentrating a mist of decontamination agent on an article's surface and to reduce a duration of aeration operations. The box includes a decontamination chamber, an aeration chamber in which residue of the decontamination agent is removed from the article's surface, a decontamination agent supply device, a decontamination agent control device, a moving device configured to reposition the article, and an air supply and exhaust device. The decontamination agent supply device converts a chemical into the mist and supplies it into the decontamination chamber. The decontamination agent control device includes vibration boards that are adjacent to internal wall surfaces of the decontamination chamber and that are ultrasonically vibrated to generate sound flows in the vertical direction thereby pressing the mist with acoustic radiation to concentrate the mist on the external surfaces of the article.
