Implementation Guide to Support Use of Elastomeric Half Mask Respirators in Healthcare

Implementation Guide to Support Use of Elastomeric Half Mask Respirators in Healthcare Authors Hines, Stella; THURMAN, PAUL; McDiarmid, Melissa A. Publication Date 2021-02-03 Abstract Elastomeric half mask respirators (EHMRs) provide similar or higher level of protection as do N95 filtering facepiece respirators (N95 FFRs) and are designed to be reused. Supply chain shortages of respirators at the onset of COVID-19 surge prompted...
