Mist shower facility and validation method thereof

Abstract

To provide mist shower facility capable of securing a predetermined chemical dust retention rate for a protective garment in a wet state.SOLUTION: A mist shower facility E1 for wetting a protective garment so as to secure a predetermined chemical dust retention ratio in a mist shower room 1, includes: hygroscopic material measuring means (filter paper moisture absorption amount measuring means 6) for measuring a moisture absorption amount of a hygroscopic material (filter paper 5) arranged in the mist shower room 1; and chemical dust retention rate calculation means 7 for calculating the chemical dust retention rate corresponding to a measured moisture absorption amount of the hygroscopic material (filter paper 5) on the basis of a function representing a relation between the moisture absorption amount of the hygroscopic material (moisture absorption amount of the filter paper) in a mist atmosphere acquired in advance and the chemical dust retention rate of the protective garment material in a wet state.SELECTED DRAWING: Figure 1
