In principle, the mask should be replaced every 4 hours. When the mask is damp, damaged or unable to fit with the face, it should be replaced in time. After leaving the operation area, you need to change the work clothes, masks, gloves and work shoes in the dressing area (semi-polluted area). The changed work clothes, gloves and work shoes should be cleaned or disinfected every day. The masks used for the second time should be disinfected intensively and treated harmlessly.
