A 7/7 CDRH Webinar covered decontamination systems for respirators, including specific methods for decontamination, evidence of potential effectiveness, and best practices and common challenges in emergency use authorization request submissions. The [Webinar](https://www.fda.gov/media/140219/download?ref=fdaweb.com) focused on N95 respirators, the disposable facepiece filtering respirators that cover a user’s airways or nose and mouth and offer protection from particulate material and an N95 filtration efficiency level.

CDRHer **Binita Ashar** said a decontaminated respirator should only be used when there are insufficient supplies of newly approved cleared or authorized respirators. She said FDA has authorized nine decontamination systems for high-level, tier-one decontamination,

CDRH assistant director for the reprocessing and personal protection team **Captain Elizabeth Claverie-Williams** said a recent agency guidance “was developed to communicate a recommended framework to our stakeholders who are developing microbicidal processes intended to make respirators safe for subsequent uses.” The guidance gives recommendations for submissions of an evidence-based approach to decontamination and bioburden reduction systems.
