April 28, 2020 - Decontamination Resource for N95 Reuse: Battelle Critical Care Decontamination System (Battelle CCDS)

Dear EMS Provider,

In order to address the current shortage of N95 filtering facepiece respirators (FFRs), the State of Arizona will soon have access to the Battelle Critical Care Decontamination System™ (Battelle CCDS™). The Battelle CCDS is designed to decontaminate N95 respirators for the novel coronavirus (SARS-CoV-2) and can decontaminate tens of thousands of N95 respirators per day. The Battelle CCDS uses low concentration, vapor-phase hydrogen peroxide to decontaminate N95s of pathogens, including SARS-CoV-2, allowing safe reuse of the same N95 up to 10 times without degraded performance.

The Battelle CCDS will be available for use by healthcare providers across Arizona free of cost beginning in early May. If your agency is interested in participating in this opportunity to utilize the Battelle CCDS to decontaminate N95s, we are requesting that you begin to prepare for this by taking the following steps:

  1.  Stop disposing of N95 masks that are free of damage (not torn or ripped) and free of visible soiling (blood, bodily fluids, or makeup).
  2. Register your agency at to receive a unique 3-digit facility code.
  3. Label each N95 mask with the Battelle-provided 3-digit facility code.
  4. Collect worn unsoiled N95s. N95s should be double bagged and boxed in preparation for shipment to the Battelle CCDS site. Please review the documents in the “Additional Resources” section for more details and instructions regarding this process.
  5. You will receive FedEx labels to ship your N95s to the Battelle site free of cost.

Upon arrival at the site of the Battelle CCDS, Battelle will log your agency’s N95s into an inventory database using barcodes. Each N95 is then assessed to ensure it is free of visible soiling (soiled masks will be rejected for disposal). Unsoiled N95s are then staged for decontamination and loaded into the decontamination chamber, where they undergo a decontamination cycle. Treated N95s are sampled to ensure complete decontamination. Finally, clean N95s are packaged and returned to the original agency via commercial carrier.
