Feature, Barrier Face Coverings for Workers.
Lisa M BrosseauJeffrey StullPublished in: New solutions : a journal of environmental and occupational health policy : NS (2022)
Face coverings have been recommended for the public and workers to prevent person-to-person transmission of COVID-19. Throughout 2020, guidelines for face coverings recommended multiple layers worn tightly against the face with straps or ear loops. This article briefly describes a new ASTM 3502 Standard Specification for Barrier Face Coverings (BFCs) and the development of performance criteria for workplace BFCs ahead of the Occupational Safety and Health Administration (OSHA) COVID-19 Emergency Temporary Standards (ETS). We also describe a method for comparing the effect on the time to receipt of an infectious dose (ID) of BFCs with varying degrees of inward leakage (personal protection) and outward leakage (source control). The role of BFCs in workplace settings during the pandemic and for exposure to infectious respiratory organisms after the pandemic remains in question. It will be important for occupational health and safety professionals to recognize their limitations in contrast with respiratory protection.
