A face mask is one of the key elements of PPE. It prevents the transmission of respiratory secretions between medical staff and patients. In fact, even non-medical personnel have been wearing them to reduce the transmission of Covid-19. A face mask is only effective when it is properly worn and handled. To wear a face mask properly, it must be properly secured over the middle of the nose. The face mask comes with a thin metal rod to make it simple to tighten the mask over the nose. This prevents respiratory secretions from escaping the mask. To maintain sterility, the mask should be handled only by the elastic ear bands. In addition, you should not remove or put on a face mask without sanitizing your hands. If your hands are not sanitized, they may contaminate the face mask and reduce its effectiveness. To maximize your PPE, always use it according to the instructions.
