DRDO designs Personnel Sanitisation Chamber and Full Face Masks

Tezpur: The DRDO has designed a full body disinfection chamber called as Personnel Sanitisation Enclosure (PSE) and a ‘Full Face Mask’ (FFM).

Personnel Sanitisation Enclosure (PSE)

Designed by the Vehicle Research Development Establishment (VRDE), Ahmednagar, a Defence Research and Development Organisation (DRDO) laboratory, this walk-through enclosure PSE is designed for personnel decontamination, one person at a time. This is a portable system equipped with sanitizer and soap dispenser. The decontamination is started using a foot pedal at the entry.

On entering the chamber, electrically operated pump creates a disinfectant mist of hypo sodium chloride for disinfecting. The mist spray is calibrated for an operation of 25 seconds and stops automatically indicating completion of operation. As per procedure, personnel undergoing disinfection will need to keep their eyes closed while inside the chamber.

The system has see-through glass panels on side walls for monitoring purpose and is fitted with lights for illumination during night time operations. A separate operator cabin is provided to monitor overall operations.

Full Face Mask (FFM)

The Research Centre Imarat (RCI), Hyderabad and Terminal Ballistics Research Laboratory (TBRL), Chandigarh, have developed face protection mask for health care professionals handling COVID-19 patients. Its light weight construction makes it convenient for comfortable wear for long duration. This design uses commonly available A4 size Over-Head Projection (OHP) film for face protection.
