Pay attention!Such epidemic prevention and disinfecting are not only redundant but also dangerous!

Not long ago, in order to prevent the epidemic prevention and disinfect, the residents were issued to the residents in order to prevent the epidemic prevention and asking residents to put the tablets into the water pipeline at the same time.

So, can the disinfection tablets be put into the sewer? What kind of way should we take for disinfection?

Or produce extremely toxic chlorine gas

According to Sun Yafei, a doctor of PhD in Tsinghua University and a member of the Chinese Popular Science Writers Association, the disinfection tablets issued by the neighborhood committee for residents should be a chlorine dioxide disinfection tablets, a preparation similar to the puffing tablet. The main component of the disinfectant is sarchloric acid and citric acid. It is not prone to reaction under solid conditions. After the water is encountered, a large amount of chlorine dioxide will be released. The oxidation of chlorine elements is very strong, which can cause viruses or bacteria to lose, so it is often added to the disinfectant.

"Under most cases, the sewer does not need to disinfect. Because the new crown virus is mainly spread through the respiratory tract droplets and close contact." Zhang Yucheng, an expert of the Shanghai Disease Prevention and Control Center, said that he should not throw the disinfectant directly into the toilet or the sewer entrance because it is stranded because it is stranded. The high concentration disinfection solution in the storage bend will continue to volatilize, release toxic and harmful gases, and then affect the health of residents.

Sun Yafei said that arranging residents to put disinfection tablets together at the same time will cause excessive chlorine dioxide in the sewer. If someone uses the toilet spirit at this time, if the hydrochloric acid in the toilet spirit is in contact with the chloroate in the disinfection tablet, it will not only produce chlorine dioxide, but also produce strong toxic chlorine gas. Therefore, although theoretically, the use of chlorine dioxide disinfection tablets in water, as long as the method is proper and the concentration is appropriate, the actual danger can be ignored. However, because the collective at the same time puts a large number of disinfection tablets in the subwainer and lacks organizational coordinated arrangements, the actual risk still exists.

Family environment is supplemented by cleaning

Disinfection is one of the important measures to cut off the way to spread the new crown virus.

Jiang Lei, an associate researcher at the Northwest Plateau Institute of the Chinese Academy of Sciences, said in an interview with a reporter from the Science and Technology Daily that there are hundreds of types of disinfection agents, and the disinfection effects and the types of pathogens are also different. The epidemic prevention, control, disinfection shall follow the requirements of the ninth edition of the "New Coronatte Virus Pneumonia Diagnosis and Treatment Plan", and try to use the disinfectant recommended by this document as much as possible in order to do the most effective disinfecting of the new coronary virus. No in the national documents, it is not pointed out that the new crown virus can be used to disinfect the new coronary virus, so disinfectants are not recommended. At the same time, a large number of disinfectants are poured into the pipeline, which may corrode the PVC pipeline and cause pipeline leakage.

He introduced that the ninth edition of the "New Coronatte Pneumonic Pneumonia Diagnosis and Treatment Plan" clearly lists several disinfectants with better effects on the new coronal virus, such as ether, 75%alcohol, chlorine -containing disinfection agent, and peroxycetic acid.

In daily conditions, the family environment should be clean and disinfected, supplemented by physical disinfection, and chemical disinfection, to avoid excessive disinfection.

For example, disinfection of the ground and walls can be equipped with a concentration of 1000 mg/liter of chlorine disinfection. The disinfection time should be no less than 15 minutes; disinfection on the surface of the tables, door handles, and faucets can be prepared at 500 mg/liter of chlorine disinfectant for 30 minutes, and then wipe it clean with water.

If it is necessary to disinfect the fabric, the steam can be circulated by 100 degrees Celsius for 20 to 30 minutes, or boil it for 15 to 30 minutes, or exposure in the sun for more than 4 hours.

In daily circumstances, the dining tools in the home can be cleaned. If necessary for disinfection, the first choice for boiling and disinfection for 15 minutes, or the flow of 100 degrees Celsius in circulation of steam is 20 to 30 minutes, or disinfect it according to the instructions. It can also be soaked with 250 mg/liters to 500 mg/liter of chlorine disinfection agent for 15 minutes. Wash it with water.

Different mop and rags are used in different areas to avoid cross -pollution.

Regarding disinfection disinfection, some experts emphasize that for different disinfection objects, disinfection in accordance with the prescribed concentration, action time and disinfection method to ensure the disinfection effect. There are different methods of use of disinfectants, some are suitable for disinfection air, and some are suitable for disinfection ground and object surface. Before use, you need to be optimistic about the instructions and scientifically use it.

In addition, disinfectants have certain toxicity and irritation. Pay attention to personal protection when formulating and use. The disinfection agent has a certain corrosion. Pay attention to wipe it with water after disinfection to prevent damage to disinfection items. The disinfection should meet the requirements of relevant specifications. Disinfection supplies should be avoided by the elderly in dementia. Electric appliances should avoid spraying. Those who need to be wiped should prevent short circuits.

It is worth noting that 75%of alcohol disinfection can be used directly. When using it, pay attention to preventing light fires to avoid fire caused by alcohol combustion. When using a disinfectant, it should be ensured within the validity period.
