You can use alcohol-based disinfection products to clean your hands. Coronaviruses are resistant to acids and alkalis, and are sensitive to organic solvents and disinfectants. 75% of alcohol can inactivate the virus, so a certain concentration of alcohol-containing disinfection products can be used as a substitute for soap and running water.
8. How to choose a mask?
Option 1: Choose a disposable medical mask when going out normally and replace it for 4 hours continuously. Replace immediately after pollution or humidity;
Option two: N95 medical protective masks can be used in the hospital or in crowded places. Replace them for 4 hours. Replace immediately after pollution or humidity.
Cotton masks and sponge masks are not recommended.
9.Use masks properly
How to use medical masks.
① The mask is dark in color on the front side, and the front side should be outward, and there is a metal clip on the nosepiece on the medical mask.
② The face opposite to the face should be the opposite side of the medical mask, that is, the side with a lighter color. In addition, pay attention to the part with the metal strip above the mask, do not wear it upside down.
③ After clearly distinguishing the front, back, upper, and lower ends of the mask, wash your hands, and hang the ropes on the ears.
④ Finally, press the metal strips on both sides of the bridge of the nose with your hands to make the upper end of the mask close to the bridge of the nose, and then stretch the mask downward so that the mask does not leave folds and covers the nose and mouth.
10.How to wear masks for special people
① Pregnant women wear protective masks and should pay attention to their own conditions and choose products with good comfort.
② The elderly and patients with chronic diseases with cardiopulmonary diseases will cause discomfort after wearing, and even exacerbate the original condition, and you should seek professional guidance from a doctor.
③Children are at the stage of growth and development, and their faces are small. Children’s protective masks should be selected.
In the special period of combating SARS, WHO temporarily recommends medical staff to use the US NIOSH-certified N95 mask (for occupational dust protection), without surface moisture resistance and blood blocking ability.
N95 masks only indicate the use of N95 filter media. The filtration efficiency of the masks meets the N95 requirements, but it is not a medical protective mask.
Medical protective masks stipulate that the filtering effect of masks must meet the N95 requirement (the filtration efficiency of non-oily 0.3μm particles is greater than 95%), and it must also have medical protection requirements such as surface moisture resistance and blood barrier.
Are masks N95 enough?
The protective effect of the mask is not only related to the filtering efficiency of the mask material but also highly related to the tightness (leakage rate) of the human face. The closeness of the respiratory protective equipment to the human face directly affects the protective effect.
According to the principle of fluid mechanics, the airflow first flows to a place with low resistance. If the mask is not tightly attached to the human face, the breathing air first passes through the mask to directly contact the human face without passing through the filter material. Without the filtering effect, the overall protective effect of the mask is difficult to guarantee, and even a 1mm gap around the mask will cause a significant reduction in protective efficiency.
Therefore, only when the filtering material has high filtering efficiency, and the tightness of the combination of the mask structure design and the human face is good, can there be a good protective effect.
Manufacturers use standard headforms when producing and testing products, but in real life, each person’s face shape is different. There is no one-size-fits-all design that can fit everyone’s face type. You need to choose a suitable mask according to your face type.
Masks are generally divided into headband and earband types according to the fixing method. When wearing, refer to the instructions on the package. Generally, check the integrity of the mask, the tightness of the headband (earband) and the connection part, and then wear the mask and adjust it—nose clip.
How to wear a mask correctly?
When wearing disposable medical masks, fully unfold the folded surface, completely cover the mouth, nose, and jaw, and then press the nose clip to make the mask fit the face completely (because the N95 mask is out of stock, Xiaobian bought ordinary masks, Photo demonstration is for reference only).
1. First, open the mask to distinguish its front and back sides. Generally, the darker side is the front side, and the smooth side feels the reverse side.
When wearing a mask, make sure that the reverse side of the mask is close to your skin inward, and the front side of the mask is outward. Don’t bring it wrong.
2. After distinguishing the front and back of the mask, hang the two ropes of the mask on the ears, and pull the mask down with your hands to cover the mouth and chin.
3. Let your fingertips press the bridge of your nose from the inside to the outside, and move it to the sides along the shape of the bridge so that the upper end of the mask is tightly pressed against your bridge of the nose so that the mask cannot easily fall down, making it fully cover the nose and nose Close your face so that you can achieve the effects of dust and haze.
