PPE information to help keep you safe in the fight against COVID-19

Standard infection control practice usually requires disposal of masks and respirators after each patient interaction. Particles that may contain viruses, bacteria, etc. get captured on the N95 respirator filter fibers during use and remain on the fibers after use. Handling or storing the respirator after use against particles containing viruses, bacteria, etc. might contribute to result in contact transmission of the disease.

We recognize the existing CDC guidelines recommending respirator reuse: When supplies of N95 respirators are depleted, a combination of approaches can be utilized to conserve supplies while safeguarding health care workers (see full CDC document here).

There is no way of determining the maximum possible number of safe reuses for an N95 respirator. Safe N95 reuse is affected by a number of variables that impact respirator function and contamination over time.

The decision to implement policies that permit extended use or limited reuse of N95 respirators should be made by the professionals who manage the institution’s respiratory protection program.

CDC provided guidance for used respirator storage: Hang used respirators in a designated storage area or keep them in a clean, breathable container such as a paper bag between uses.

To minimize potential cross-contamination, store respirators so that they do not touch each other and the person using the respirator is clearly identified. Storage containers should be disposed of or cleaned regularly.
