District 123 is fortunate to be able to provide a custom-fitted N95 mask to our nurses and custodial staff. The masks will be used only when interacting with contaminated surfaces. To properly fit the mask, Director of Operations, Leo Cassidy fits a hood over the person’s head, without a mask. Then a bitter solution is sprayed into the hood. Once the subject can taste it the test pauses, and then they are custom fitted for an N95 mask to use.
