Beginning in March 2020, many hospitals and other healthcare employers have turned to decontaminating single-use N95 respirators to be reused multiple times, given reports of PPE shortages. Several states have now begun reopening but have not taken substantial action to increase PPE production. Instead states and employers are relying on potentially dangerous decontamination methods. NNU has evaluated the available evidence on decontamination methods and determined NO METHOD IS BOTH SAFE AND EFFECTIVE.
