COVID-19: Cleaning & Disinfecting of PPE for Effective Reuse Webinar

About the Webinar

Originally presented April 29, 2021

Watch the Webinar

The COVID-19 pandemic has caused unprecedented disruption in supply chains across multiple sectors including the shortage of critical personal protective equipment (PPE). In addition to hand washing and surface disinfection, various PPE items are used to prevent contact with the virus via droplet/aerosol transmission, thereby reducing potential exposure to SARS-CoV-2, the virus that causes COVID-19. Effective, low-technology, disinfection methods for certain specialized-use items, such as filtering-facepiece respirators, medical-use masks, face shields, and body coveralls, as well as non-specialized items, like procedural masks, face coverings, clothing, and shoes, are limited outside of healthcare setting applications.

EPA researchers are undertaking research evaluating the effectiveness of selected disinfection/cleaning technologies and commercial off-the-shelf products for these specialized and non-specialized PPE items for potential reuse during the pandemic. The evaluation includes disinfection efficacy tests coupled with wear cycles and integrity tests on the PPE materials after exposure to disinfectants to reflect real-world use of such items and to help determine whether it impacts the wearer. During this webinar, researchers will discuss their evaluation of disinfection techniques and cleaning protocols that can be used for the disinfection of disposable and reusable PPE contaminated with viruses. This information will help responders and the general public understand what type of low-tech disinfection/cleaning is most effective without the loss of integrity and relieve pressure on the supply chain which has struggled to keep up with demand of PPE.
