Novel coronavirus is a relatively difficult infectious virus, which can survive in the air for a long time. Therefore, we must do a good job of disinfection and protection. We should clean up regularly and reduce the infection of virus. Can novel coronavirus be sterilized with alcohol? Let's novel coronavirus related to alcohol disinfection.
Can novel coronavirus be sterilized with alcohol?
Some experts pointed out that 75% alcohol can effectively inactivate the virus. But at the same time, it should be noted that alcohol belongs to flammable and explosive materials. Now we store and use a large number of alcohol. We must pay attention to the fire hazards caused by alcohol.
be careful:
75% concentration is the best. Do not spray large amounts of alcohol on infants and adults to prevent alcohol allergy. Pay attention to open fire to prevent fire.
75% concentration of alcohol cotton or alcohol, not only can kill the virus, but also cheap.
If the alcohol concentration is too high (for example, 90%), it needs to be diluted to about 75% before use, otherwise the virus can not be effectively killed.
Operation method:
Direct use. Mobile phones, remote controls, computer keyboards and various electrical switches, buttons can be used to disinfect.
Precautions for alcohol disinfection
1. Before using alcohol, clean the surrounding flammable materials, and do not spray directly in the air. Alcohol has a low ignition point and is easy to ignite in case of fire and heat. Do not close to the heat source and avoid open fire when using. To disinfect the surface of electrical appliances, turn off the power supply first and wait for the appliances to cool down. If you wipe the kitchen stove with alcohol, turn off the fire source first, so as to avoid deflagration caused by alcohol volatilization. When using, the upper cover of the container must be closed immediately after each use, and it is strictly forbidden to open it.
2. When using alcohol, it is necessary to ensure indoor ventilation. The used towel and other cloth cleaning tools should be cleaned with a large amount of water and stored in airtight condition, or put in a ventilated place to dry.
3. It is not suitable to store a large amount of alcohol at home, but to buy small bottles of alcohol, so as to avoid fire safety risks.
4. It should be stored away from light to prevent dumping and damage. Containers using alcohol must be sealed reliably. Containers without covers are strictly prohibited. The glass should be kept away from falling. The remaining alcohol in the home should not be placed in the balcony, stove and other heat source environment, and should not be placed near the power socket, wall edge, table corner, etc., to prevent accidental collision and dumping. It can be stored in a cool place such as cabinet, cover tightly when storing, and label well to avoid volatilization.
5. Alcohol should be kept out of the reach of children. For older children, parents can explain the characteristics of alcohol to their children and teach them not to play with alcohol, let alone ignite it with fire.
Novel coronavirus is afraid of 5 things
1. Novel coronavirus is afraid of high temperature
The novel coronavirus can not withstand high temperatures after scientists have been racing against time to seize the clock. They survive well at low temperatures, but once the temperature is above 56 degrees, they are not infectious. At this high temperature, it takes only 30 minutes to kill the virus completely. Therefore, to prevent it, we must remember that the food should be cooked before eating.
2. Novel coronavirus is most afraid of high concentration alcohol
The novel coronavirus will lose its activity in over 75% of alcohol and chlorine containing disinfectants, and will no longer infect human beings.
3. Novel coronavirus is afraid of ultraviolet rays
At ordinary times, we all know that the use of ultraviolet rays can achieve certain disinfection and sterilization effect. This method is also novel coronavirus, which can be cleaned up by ultraviolet rays for 10 minutes.
4. Novel coronavirus is afraid of leaving the host
The novel coronavirus can survive only within the host. If it leaves the host, it can only survive for about 2 hours in the air. It will take much less time to survive in the air for 24 hours compared with the flu.
5. Novel coronavirus is afraid of powerful immunity
Among the patients with new infection, there are more middle-aged and elderly people over 40 years old. Among the death cases, there are many people with old age, poor immunity and chronic medical records. As long as we improve the body's immunity, under your strong immune system, the virus will be driven out.
How to prevent novel coronavirus
Take isolation measures:
This is the novel coronavirus Zhong Nanshan's measures after the characteristics of the new coronavirus. This has proved to be a very effective approach. Especially don't go to crowded places. At present, most people have been isolated at home for a period of time, and only for a period of time, they will receive good results.
If you must go out, you must wear a good mask, especially to the hospital, station and other places with dense personnel. The mask can effectively isolate the virus in the air.
Do a good job in disinfection:
We need to disinfect the key parts of the home and office, such as door handle, remote control and other tools, bathroom, toilet and other places. In general, 75% medical alcohol is used for wiping or spraying. Wash your hands when you go out and go home, and then disinfect with alcohol. It is better to spray alcohol on the coat, or irradiate it with ultraviolet lamp.
In addition, we must pay attention to improve their immunity. Novel coronavirus is also infected. What are some people's symptoms rather mild, and others are critical or even death? The main reason is that immunity is high or low.
