Brief summary
The study aim is to compare the user seal check and fit test between new and decontaminated N95 respirator. Institutions around the world have explored the options of decontamination and reuse of N95 respirators. Current literature has shown promising results with the use of aerosolised or vapour-phase H2O2 to decontaminate N95 masks. Although multiple studies have been done, there are only a few studies which evaluated fit testing of the decontaminated respirators. Most of these studies tested on a small sample size. We believe quantitative fit testing on a larger group of individuals is essential. This will ensure that tight seal can be maintained on healthcare workers with different facial features after H2O2 decontamination of the N95 masks.
Interventions
Using the participants best fitted N95 mask, it will be checked to ensure it is not visually damaged or soiled, and then place it in a sealed Tyvek pouch for decontamination. We will follow the instructions as per STERIS Healthcare on “Decontamination of Compatible N95 Respirators Using the STERIS Sterilization Systems".
60 individuals who have completed a successful fit test with their best-fitted mask will be invited to take part. Their best-fitted mask will be labelled with a study identific
Using the participants best fitted N95 mask, it will be checked to ensure it is not visually damaged or soiled, and then place it in a sealed Tyvek pouch for decontamination. We will follow the instructions as per STERIS Healthcare on “Decontamination of Compatible N95 Respirators Using the STERIS Sterilization Systems". 60 individuals who have completed a successful fit test with their best-fitted mask will be invited to take part. Their best-fitted mask will be labelled with a study identification number. They have to wear the mask for one hour, check it is not visually damaged or soiled, and then place it in a sealed Tyvek pouch for decontamination. The instructions as per STERIS Healthcare on “Decontamination of Compatible N95 Respirators Using the STERIS Sterilization Systems” will be followed. After completion of one cycle of decontamination, we will inspect the masks and discard the ones with obvious structural damage or deformity. They will be counted as not fit-for-purpose. Using those without any damage or deformity, the participants will then carry out a user seal check and a quantitative fit test. They will provided with, 1) their own best-fitted N95 mask which has been through one cycle of H2O2 decontamination, 2) a new N95 mask with the same brand and size. Both masks will have their study identification number labeled and placed in a plastic bag. The test will be observed throughout by personnel trained in the use of the PortaCount machine and any breach of protocol will be addressed by recommencing the test. The user seal check result and the fit factor for both new and decontaminated N95 masks will be recorded.
