AI Technical Summary
Existing space decontamination methods using high concentrations of decontamination agents like hydrogen peroxide and peracetic acid pose safety risks and are less effective in areas with difficult air circulation.
A method and device that use a solution containing hydrogen peroxide at 1 w/v% to 6 w/v% and acetic acid at 1 w/v% to 10 w/v%, without peracetic acid, which is sprayed or vaporized to generate a decontamination gas, maintaining humidity between 60%RH and 85%RH, and controlled by a system to manage concentrations of acetic acid and hydrogen peroxide between 5 ppm and 100 ppm.
The method and device achieve high decontamination efficacy with enhanced safety by suppressing peracetic acid and hydrogen peroxide concentrations, ensuring effective decontamination even in areas with difficult air circulation, and allowing safe handling and storage of the solution.
