Disinfection is important, but to prevent

In the current global outbreak, disinfection is a daily priority, and it is always tempting to ask three questions:

“Disinfection is not thorough？？”

“If you have a baby/ pet, that's ok？”

“Does this disinfection leave any traces of the virus？”

Brothers, don't worry,  As long as you know exactly how to use disinfectants, disinfection is actually quite simple, Do not operate blindly, otherwise easy to cause poisoning, explosion and other adverse consequences oh ~~

Today I will give you a small science ~~~

Alcohol, only used in vitro elimination, the general occasion can be used.Such as hand and surface cleaning and disinfection.

However, the alcohol concentration is too high to be used for air disinfection and other purposes. Many people put alcohol in a spray bottle or humidifier to sterilize the air, which is not a good practice and can easily cause a fire. Therefore, it is not recommended to spray alcohol into the air at home for elimination.

我们The concentration of the virus in the air in our homes is unlikely to be high enough to spread,  Therefore, there is no need for air disinfection, keeping doors and Windows open regularly for ventilation can be.

Not all disinfectants can be targeted to novel Coronavirus, with disinfectant is the basis of virus prevention.Chlorine-containing disinfectants (84 disinfectants, bleach powder, etc.), 75% medical alcohol, chloroform and other fatty solvents can effectively eliminate live viruses. We mainly use 75% medical alcohol and 84 disinfectants.

Alcohol burns easily and fires occur when the concentration of ethanol in the air exceeds 3%. Ventilation should be maintained when alcohol is used in large quantities. Do not spray a large area when the human body is disinfected, wipe hands can, do not close to the source of fire, heat source before volatilization thoroughly.

The 84disinfectant should be first diluted according to the instructions and placed in a plastic container.It can be used directly on the table, on the ground, on clothes and other objects. Wear masks, rubber gloves and waterproof aprons to protect the skin, mouth, nose and eyes.

Use the 84disinfectant alone. Do not mix it with other disinfectants. Especially can not be used with clean toilet spirit, otherwise it will produce toxic chlorine gas, serious people even poisoning death.

There are also some professional medical, industrial disinfectants, it is best not to use at home.It is not recommended to make a disinfectant, general people grasp the bad proportion and chemical reaction, easy to occur dangerous.

To avoid "dead ends", there are three key points for home disinfection:

◆ The ground, table top, switch, door handle, hot water bottle, toilet, bedside table, etc. Use effective chlorine 250~500 mg/l of 84 disinfectant to wipe, after 15 minutes, scrub clean with clean water,at least 1 time a day;

◆ Towel, clothing, quilt cover and other fabrics, with effective chlorine 250~500 mg/l of 84 disinfectant immersion 1 hour;

◆Water cup, teacup, tableware and small toys can be soaked in bleach powder and potassium permanganate for 15~30 minutes, or boiled with water for 15 minutes, sterilized at any time after use, and then washed clean with running water;

◆ After receiving takeout and express delivery, throw out the package and wash your hands carefully.If you are really worried, you can spray 75% medical alcohol on the surface of the product.

According to Prof. Nan-shan Chung, novel Coronavirus can survive and transmit in stool, so it should cut fecal-oral transmission and pay attention to some little details of life:

◆ Toilets and toilets should be disinfected.Put the lid on the toilet when flushing;

◆ To the small area that sewer closes a gender not strictly, if discover backwater, leak, should strengthen the sealing sex of closestool or toilet implement,Rural areas that use dry latrines need to disinfect latrines regularly;

◆ Everyday objects such as mobile phones, keys, doorknobs, keyboards, mice, etc.Pay attention to regular disinfection, especially after going home;

◆ The family that has a child, should pay attention to ground, furniture more disinfect, lest the child touch dirty thing hind eats a hand and be infected;

◆ Eat less raw food and drink no raw water.Vegetables must be washed, cooked after consumption, eat fruits to be fully washed;

◆ It is suggested that separate meals should be carried out in the family and a pair of public chopsticks should be prepared.

Jin Xiangyu, chief science communication expert at the China Society of Textile Engineering, said the online masks can be sterilized by heating them in a microwave oven or hair dryer and rubbing them with 75% alcohol. They can be reused.None of this is desirable.

Heating with microwave oven, electric oven, hair dryer, steamer, etc., will destroy the structure of the internal filter layer. In the heating process, it is also easy to blow the attached droplet into the face, which will easily cause secondary pollution.

Moreover, the outer surface of the mask has been "water-repellent treatment", so it is difficult for the alcohol to penetrate into the mask, and it is difficult for the surface coating to sterilize the inside.On the other hand, alcohol damages the waterproof structure of the mask outer layer, which will enhance the absorption of water and accelerate the failure of the filter layer.

If the following abnormal situations occur in the process of disinfection at home, everyone should be familiar with and master the first-aid method, and treat themselves in a timely manner.

When alcohol catches fire on your body, cover the burning area with wet clothing.When burned, do not shout because Shouting can cause severe respiratory tract burns.Seek medical advice immediately after the fire is out.

酒精引燃其他物品时，用When other articles are ignited by alcohol, cover the ignition point with wet clothes and wet sheets, transfer inflammable and explosive articles in the first time, and use CO2 and dry powder fire extinguisher to extinguish fire, and use sand and soil cover to extinguish fire outside.

Remove contaminated clothing and rinse quickly with plenty of water.

Lift eyelids, flush with running water or saline, and seek medical advice immediately.

Drink a lot of milk or water,timely dial 120 emergency call to go to the hospital.

Get away from the scene quickly, move to the fresh air, and call the emergency number in time.

It is very important to do a good job of disinfection, but at the same time of disinfection at home and improving safety awareness, we should also master scientific methods to avoid adverse consequences.▲ Have you learned??
