? We all know that New Coronavirus is a more difficult infectious virus. It can survive in the air for a long time. Therefore, we must do a good job of disinfection and protection, and we should clean up regularly and reduce the infection of virus. Can New Coronavirus sterilize it with alcohol? Let’s take a look at the relevant knowledge of alcohol disinfection New Coronavirus.
Can New Coronavirus disinfect with alcohol?
experts pointed out that 75% of alcohol can effectively inactivate the virus. But at the same time, it should also be noted that alcohol is flammable and explosive. Now we store and use it in large quantities. We must pay attention to the potential fire hazards caused by alcohol.
Note:
75% concentration is the best. Do not spray a large amount of alcohol on infants and adults to prevent alcohol allergy. Pay attention to open fire to prevent fire. Not only can alcohol kill the virus at a concentration of 22200015%, but also alcohol can kill the virus.
if the alcohol concentration is too high (e.g. 90%), it needs to be diluted to about 75% before use, otherwise it cannot effectively kill the virus.
operation method:
direct use. It can be used to disinfect mobile phones, remote controls, computer keyboards and various electrical switches and buttons.
Precautions for alcohol disinfection
1. Before using alcohol, clean the surrounding inflammables and combustibles, and do not spray directly in the air. Alcohol has a low ignition point and is prone to spontaneous combustion in case of fire and heat. When using it, do not get close to the heat source and avoid open fire. Disinfect the surface of electrical appliances. Turn off the power supply first and wait until the electrical appliances are cooled. If you wipe the kitchen stove with alcohol, turn off the fire source first to avoid deflagration caused by alcohol volatilization. When in use, the upper cover of the container must be closed immediately after each use, and it is strictly prohibited to place it open.
2. When using alcohol, it is necessary to ensure indoor ventilation. Used towels and other cloth cleaning tools shall be cleaned with a large amount of water and stored in a closed manner, or put in a ventilated place to dry.
3. It is not suitable to store a large amount of alcohol at home. You can buy small bottles of alcohol to be enough, so as not to leave potential fire safety hazards.
4. Store away from light to prevent dumping and damage. Containers using alcohol must be reliably sealed. Uncovered containers are strictly prohibited. Avoid storing in glass bottles to prevent falling and damage. The alcohol left at home should not be placed in the heat source environment such as balcony and stove, or near the power socket, wall and table corner to prevent accidental collision and dumping. It can be stored in a cool place such as a cabinet away from light. When storing, the cover shall be tightly covered and labeled 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 children, teach children not to play with alcohol, let alone ignite it with fire.
New Coronavirus is afraid of 5 things:
1 and New Coronavirus are afraid of high temperature
. Scientists have been racing against each other for several seconds, and found that New Coronavirus can not withstand high temperatures. They survive well at low temperature, but once the temperature reaches more than 56 degrees, they will not have infectious activity. In this high temperature, they will completely kill the virus as long as 30 minutes. So if you want to prevent it, you must remember to cook the food thoroughly before eating.
, New Coronavirus is most afraid of high concentration of alcohol
New Coronavirus over 75% alcohol, and chlorine containing disinfectant will soon lose its activity, will no longer infect people.
, New Coronavirus is afraid of ultraviolet
. We all know that ultraviolet radiation can achieve certain disinfection and bactericidal effect. This method is also applicable to New Coronavirus, which can be cleaned up by ultraviolet irradiation for 10 minutes.
, New Coronavirus is afraid to leave the host
New Coronavirus can only survive in the host. If it leaves the host, it will only survive for about 2 hours in the air, and it will take much less time to survive in the air for 24 hours compared with that of the H1N1.
, New Coronavirus is afraid of powerful immunity.
of the new infections, there are more middle-aged and elderly people over 40 years old. In the case of death, there are many people with large immunity and chronic medical records. As long as we improve our immunity, the virus will be driven out under your powerful immune system.
How to prevent New Coronavirus
from doing quarantine work well:
, this is the measures put forward by academician Zhong Nanshan after studying the characteristics of New Coronavirus. Facts have proved that this is a very effective method. Especially don’t go to crowded places. At present, most people have been isolated at home for a period of time. If they stick to it for a period of time, they will receive good results.
if you have to go out, must wear masks , especially in hospitals, stations and other densely populated places. Masks can effectively isolate viruses in the air.
do a good job in disinfection:
we should disinfect the key parts of the home and office, such as door handles, remote controls and other tools, bathrooms, toilets and other places. Under normal circumstances, wipe or spray with 75% medical alcohol. 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 under ultraviolet lamp.
in addition, must pay attention to improving their immunity. what’s more, New Coronavirus is infected with it. Why do some people have mild symptoms while others are critical or even death? The main reason lies in the level of immunity.
