Certain methods of decontaminating medical face masks for repeated use during the COVID-19 pandemic appear to damage the masks’ integrity and protective function, according to research by a University of Massachusetts Amherst environmental health scientist.
“Some treatments for decontamination had no impact on respirator performance, while other treatments resulted in substantial damage to masks,” writes Richard Peltier, associate professor in the School of Public Health and Health Sciences and lead author of the paper published July 16 in the journal Infection Control and Hospital Epidemiology.
Peltier received a fast-track grant from the National Science Foundation in May to study the impact of various sterilization techniques authorized for emergency use by the Food and Drug Administration (FDA) in light of the shortage of medical face masks, also known as N95 respirators.
“Given the global N95 shortages, clinicians face a choice: wearing a used, and potentially infected respirator, or wearing one that was decontaminated through a process that may affect the integrity of the respirator,” says Peltier, whose co-authors include doctors and researchers at New England Baptist Hospital in Boston and UMass Memorial Medical Center in Worcester.
