Hi Jim, I am writing because my coworkers and I think we may be able to help develop an ozone-based system for decontamination of PPE and equipment. We are subcontractors to a DOE lab that operates the Nevada National Security Site and have experience with science and engineering related to detection or radiation and effluence. We are interested in knowing whether you received input from Dr. Fauci or others regarding sterilization of PPE. In your March 19th letter, you state that "testing is needed to verify that ozone does not damage the masks, length of time required to inactivate the Sars-CoV-2 virus, whether there are limits on how many times a disposable mask might be sterilized, and the length of time required for sterilization. Some N95 masks contain activated charcoal to remove odors or volatile compounds. Activated charcoal is used in the SoClean machines to inactivate the ozone; guidelines are needed to specify which masks types are compatible." All of these are extremely relevant requirements and solutions to this problem were needed weeks/months ago, so the more we can approach this as a team with those who may be testing the effectiveness of ozone to kill COVID-19 the better.
