Battelle has announced an [emergency use authorization](https://www.fda.gov/media/136529/download?ref=fdaweb.com) for its Critical Care Decontamination System for decontaminating respirator masks. It says each device system is capable of decontaminating up to 80,000 respirator masks per day using concentrated, vapor phase hydrogen peroxide. The masks are exposed to the validated concentration level for 2.5 hours to decontaminate biological contaminates, including caronavirus, according to the company. Battelle says the system can decontaminate the same respirator mask up to 20 times without degrading the mask’s performance.
