How to use 84 disinfectant and alcohol?
Right now, the "war" against the new crown pneumonia virus is not over yet. Many families stock some disinfection supplies at any time, such as 84 disinfectant and alcohol.
Different disinfection products have different usage methods, scopes and storage methods. How should citizens use them correctly? In this regard, the director of the Department of Infection Management of Hangzhou People's Hospital explained in detail.
Alcohol kills do not spray
The new crown pneumonia virus is sensitive to heat, and lipid solvents such as ether, 75% ethanol, chlorine disinfectant, peracetic acid and chloroform can effectively inactivate the virus.
According to the safety tips for home use disinfection products during the epidemic prevention and control period issued by the Hangzhou Emergency Management Bureau, disinfection products that are not subject to special controls such as 75% alcohol, chlorine-containing disinfectants, and peracetic acid can effectively inactivate viruses, but they also have Dangerous characteristics such as flammability, poisoning and corrosion. If used and stored improperly, it is very easy to cause safety accidents such as fire, poisoning and burns.
Then why alcohol can be sterilized? The director introduced alcohol (ethanol), one of the most commonly used disinfectants in medicine, and the most widely used disinfectant. It is most commonly used for the disinfection of non-damaged skin and the surface cleaning and disinfection of objects.
Alcohol is soluble in water and has a certain degree of fat solubility. The mechanism of alcohol sterilization and virus killing is: the fat solubility of alcohol can destroy the biomembrane composed of bimolecular phospholipids, causing the structure and dysfunction of biomembrane to cause death. Higher concentrations of alcohol can destroy the "order" of the membrane structure, thereby destroying the function of the membrane, and leading to the death of "membrane" microorganisms.
The director said that the new type of coronavirus belongs to the new type of coronavirus of the genus β and has an envelope, so it can be killed by alcohol. Alcohol acts and destroys its lipid molecular envelope, which can quickly kill the virus. Therefore, alcohol can be used to eliminate the current novel coronavirus epidemic prevention and control.
Which details should be paid attention to when using alcohol at home? The director said that alcohol is a highly flammable substance, 75% ethanol alcohol is about 22 degrees Celsius lightning, and the fire hazard belongs to Class A. Therefore, in the process of using 75% ethanol for disinfection, spray disinfection is prohibited indoors. Wipe should be used for disinfection and leakage should be avoided during the disinfection process. The concentration in the air should not exceed 3% to prevent fires. Keep it for a period of time after disinfection. ventilation.
Second, when using 75% alcohol for disinfection, avoid heat sources such as cigarette butts, open flames, and electric irons. When disinfecting facilities and equipment, power-on equipment must be de-energized before disinfection. After disinfection, leave it for more than ten minutes for power-on use. If alcohol catches fire during use, use dry powder, carbon dioxide and sand to cover. Because 75% alcohol is flammable and explosive, it is not allowed to be carried on subway travel, high-speed rail and other occasions.
84 disinfectant should be prepared with cold water
In addition to alcohol, 84 disinfectant is a common household disinfection product for residents, so what are the precautions for residents to use 84 disinfectant during the epidemic? Can 84 disinfectant disinfect everything? What should I pay attention when mixing 84 disinfectant?
The director told the author that 84 Disinfectant is a colorless or light yellow liquid. It is an effective disinfectant with an effective chlorine content of 5.5% to 6.5%. It is widely used in hotels, tourism, hospitals, food processing industries, households, For the sanitation and disinfection of kindergartens, the main disinfection methods are wiping, spraying and mopping.
In his opinion, 84 disinfectant is irritating and corrosive to a certain extent and must be diluted before use. Generally, the dilution concentration is 1:500 and 1:200, and the immersion time is 10-30 minutes. All items to be disinfected should be immersed in water. After disinfection, they should be rinsed with clean water before use.
84 disinfectant has strong bleaching effect and corrosiveness. It is best not to disinfect clothes and iron items. It must be used at a low concentration and not soaked too long. 84 disinfectant is a chlorine-containing disinfectant, and chlorine is a volatile gas, so the container containing the disinfectant must be covered, otherwise the disinfection effect will not be achieved.
He suggested not to mix 84 disinfectant with other detergents or disinfectants, because this will increase the concentration of chlorine in the air and cause chlorine poisoning. 84 disinfectant should be placed out of the reach of children to avoid accidental ingestion.
The validity period of 84 disinfectant is generally 1 year. Pay attention to the production date when purchasing and using it. If it is placed too long, the effective chlorine content will decrease and affect the disinfection effect. 84 disinfectant is irritating to the skin. Wear gloves when using it to avoid contact with the skin. 84 disinfectant should be prepared with cold water for one-time use. Do not dilute with hot water above 50 degrees. Keep it under 25 degrees and avoid light. In addition, the items after disinfection and cleaning should be dried directly, and they should not touch other containers again.
How to configure 84 disinfectant? In this regard, the director said that according to the preparation ratio, according to the number of disinfected items, mark the arrival of disinfection water on the disinfection bucket. Clean the items to be disinfected for later use, wear gloves, use a disinfectant bucket to receive cold water to the designated mark, pour a good amount of 84 disinfectant into the bucket, stir gently by hand, and complete the disinfectant preparation. Place the cleaned items in the prepared disinfectant, cover and soak for 30 minutes, take out the disinfected items one by one after 30 minutes, rinse them under clean water, and dry them in the designated place. The remaining solution containing 84 disinfectant can be used to soak rags, clean the floor and bathroom, etc., take off the gloves, complete the disinfection, and make a disinfection record.
