1、 Remember three words
1. Wear and remove. Do "wear for a while, pick for a while". Do not wear the mask for a long time in hot environment. When conditions permit, you can wear it for a while and pick it for a while. Wear it when there are many people, and take it off when no one is around; put it on indoors, and take it off outdoors; put it on when people talk, and take it off when they leave.
2. Wear and sun. Do "wear one, bask in the sun". Masks should be clean and dry. This "sun", not in the sun, is hanging in the shade.
3. Wear and belt. Do "wear one, take one". Wear a mask in summer. It is easy to lose, wet or damage. Take a spare one.
2、 Keep three
1. Keep facing and always turn out.
2. Keep the mask dry all the time.
3. Keep throat moist all the time.
3、 Master seven key points
1. Check the inner and outer layers before wearing. Don't wear the wrong direction, and don't turn it upside down. Hold the bridge of the nose and cheek. The air tightness of the valve body must be checked for the mask with valve;
2. Try to speak less or not when wearing masks;
3. Face to face avoid people who do not wear or remove masks;
4. Take off the mask in an open and well ventilated place outdoors, and do deep breathing and chest expansion exercise;
5. Drink more water to prevent heatstroke. A small number of times can be taken. Remember not to wait until you are thirsty to think of drinking water;
6. Save the mask and replace it. Disposable respirators do not have to be replaced at one time. In general, it can be reused. However, when it is found that the outer layer is fluffy, the inner layer is stained, and the cover body is soft and damp, it can no longer be used. Masks worn continuously for one day must be replaced. Family members should pay attention to the special use of masks. The mask worn when going to the hospital or high-risk area cannot be worn repeatedly. It must be sealed and disinfected before being discarded as required.
7. Apply appropriate amount of Vaseline to the back of ear and bridge of nose to prevent wearing and wearing the skin for a long time. After taking off the mask, wash your hands and massage your nose, ears and cheeks. You can also apply prickly ash powder.
8. Take heatstroke prevention drugs (ren Dan, cool oil, etc.) with you.
