WVU PPE Decontamination COVID-19 Pandemic PPE Shortage Support Project
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 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.
Mask Collection • The WV National Guard collects masks from throughout the state and drops them off at WVU for decontamination
Setup • Used masks are unpacked and placed on shelves • N 95 masks are laid flat on metal wire racks • Surgical masks are hung by earloops on hangers
Decontamination Treatment • Vaporized Hydrogen Peroxide or Chlorine Dioxide gas fills the room to the desired concentration and contact time to disinfect the masks
Decon Cycle Tracking After the decon cycle is complete, the masks are marked with a dot to indicate the number of decon cycles (5 dots = 5 cycles)
Returning the masks • The masks are packed up and returned to the National Guard. • The National Guard distributes them throughout the state
