COVID-19 pandemic has created unforeseen public health challenges including the disruption of a steady supply of personal protective equipment (PPE) for health care workers (HCWs). Several approaches have been evaluated for safe disinfection of used PPEs to allow their selective reuse. We have recently shown that Vaporized Hydrogen Peroxide (VHP) is a safe, easy-to-scale up, economical and environment friendly method to disinfect PPE (coveralls, N-95 masks and face-shields) without compromising their quality and integrity even after repeated cycles of disinfection (Saini et al., 2020). Based on this method, we have operationalized a PPE disinfection research facility at All India Institute of Medical Sciences (AIIMS), New Delhi, a tertiary care medical centre in India. Considering the immense potential of this approach, we have been repeatedly approached by various hospitals to provide a detailed standard operating guideline to run such a facility. Herein, we present a step-by-step illustrative guide that we believe would be helpful to operationalize a PPE disinfection facility at health care settings. This guide incorporates elements and steps of biosafety necessary to handle used PPE during COVID-19 settings and can be adapted for various methods of PPE disinfection, and various pathogens.
