To address approaches to the respirator approval process in the current landscape for both occupational and non-occupational use of respirators, the National Academies of Sciences, Engineering, and Medicine's Standing Committee on Personal Protective Equipment for Workplace Safety and Health convened a virtual workshop, Current Issues in the Assessment of Respiratory Protective Devices: Nontraditional Workers and Public Use on August 4-5, 2020. Additionally, the workshop considered gaps in respiratory protection for outdoor workers and the general public. This publication summarizes the presentation and discussion of the workshop.
