This walkthrough the enclosure is designed for personnel decontamination, one person at a time.

The portable system is equipped with sanitizer and soap dispenser. The decontamination is made using a foot pedal at the entry.

On entering the chamber, an electrically operated pump creates a disinfectant mist of hypo sodium chloride for disinfecting.
