The Spring Festival holiday has ended, and many units have gradually entered the state of returning to work, but the epidemic prevention work still cannot be relaxed! Academician Zhong Nanshan once said in an interview that the epidemic should reach its peak in a week or ten days. If everyone must return to work during this period, then the following three details must be paid attention to: 1. Masks must be worn in high-risk areas of the office, especially in elevator rooms. The air is extremely stagnant and the flow of people is the largest, which requires great attention. It is suggested that you must wear a mask when taking the elevator, and don't touch the elevator button directly. It is recommended to block the button with a tissue. Conditional units must often disinfect the elevator room, especially the button area. 2. The second highest risk: canteen/restaurant. It was time for dinner, and a large number of people crowded into the dining hall. At this time, it is the area with the largest flow of people and the highest density. It is suggested that you take off your mask at the last moment when you sit down to eat, eat at the wrong peak, avoid eating face to face, and avoid chatting while eating; Or pack it back to the station and eat it alone. 3. The third high-risk office. People come and go in the office, which is basically a fixed flow of people. Although the danger is less, it still needs attention. It is recommended to wear a mask and keep a moderate distance from the conversation; Keep the office well ventilated, and the office supplies that you often contact should be disinfected with alcohol. Wash your hands in the office as soon as possible. Wash your hands before eating. If you have been to the elevator or the high-risk area of the canteen, be sure to wash your hands when you come back; Go out and come back. Wash it now!
