Since 2015, the federal government spent $9.8 million on two projects to prevent a mask shortage but abandoned both projects before completion. [81] A second BARDA contract was signed with Applied Research Associates (ARA) of Albuquerque, to design an N95-rated mask that could be reused in emergencies without reduced effectiveness.
Sanitisation is not always simple. Alcohol disrupts N95 mask microfibres' static charge. [89] Chlorine fumes may be harmful. [89] A Singaporean study found no contamination on masks after brief care of COVID-19 patients, suggesting masks could be reused for multiple patients. [90]
Do N95 masks work better than surgical masks? A draft proposal from the CDC suggests the two are equivalent in certain hospital settings.
Just a single face mask, according to a study in Environmental Advances, can release as many as 173,000 microfibers per day into the seas. And a recent National Geographic report cites a far ...
In early March, the country had about twelve million N95 masks and thirty million surgical masks in the Strategic National Stockpile (SNS), but the DHS estimated the stockpile had only 1.2 percent of the roughly 3.5 billion masks that would be needed if COVID-19 were to become a "full-blown" pandemic.
