The color face of the mask is outward and the metal face is upward; fasten the rope to fix the mask, or wind the rubber band around the ears to make the mask close to the face; the disposable medical mask should completely cover the nose and chin; press the metal piece on the disposable medical mask along the bridge of the nose to make the mask close to the face. When removing the mask, try to avoid contacting the outside of the mask as this part may have been infected by bacteria. After removing the mask, put it into tape or paper bag, and then put it into the dustbin with cover.

  Most color disposable medical masks are made of chemical fiber fabrics, which have poor air permeability and chemical odor, and can cause respiratory tract damage. Qualified disposable medical masks are made of gauze and non-woven fabrics. It's unscientific to make it messy and not clean it up in time. After wearing the mask for 4-6 hours, many bacteria will accumulate and need to clean the mask every day.

  Do not wear disposable medical mask for running, because the demand for oxygen during outdoor sports is greater than usual, and the mask may cause dyspnea or even organ hypoxia, which leads to very serious consequences. After wearing the mask, it should cover most of the area below the mouth, nose and eyes. The edge of disposable medical mask should be close to the face, but please pay attention not to affect the vision.

  The plan to prevent the side leakage of face mask is a technical requirement, which aims to prevent the air from being inhaled through the gap between face mask and face without filtering. Air, like water, has less resistance. It moves first. When the shape of disposable medical mask is not close to the face, the dangerous substances in the air will leak from the position not close to the face and enter the human respiratory tract. Workers should check the tightness of masks on time. The aim is to ensure that workers choose masks of different sizes and wear them according to the correct procedures.
