Current Capacity and Customers • HSC EH&S team is collaborating with the West Virginia National Guard to help alleviate the PPE shortages within the state healthcare systems. • We are currently disinfecting (decon), on average, 1000 N 95 and surgical masks each week from various aspects of the state healthcare system including: • • Nursing homes EMS County Homeland Security departments National Guard units. • In the near future, we will be supporting WVU Health Sciences faculty, staff, and students who need masks for clinical and research purposes.

Disinfection Process • The masks are disinfected using either chlorine dioxide gas or vaporized

Disinfection Process • The masks are disinfected using either chlorine dioxide gas or vaporized hydrogen peroxide (VHP). • Both methods have been validated for use with N 95 masks; ensuring the masks are properly disinfected, without compromising the integrity or function of the mask. • Disinfection provides a 6 log reduction (10^6 or 1 million) of microorganisms present. • Under normal usage, N 95 masks would not have that level of biological contamination, therefore would be free of harmful pathogens for future usage. • The masks can be decontaminated 15 times, as long as the mask is not visually discolored, broken/frayed straps, or has noticeable wear.
