What are the common disinfection methods?
2. Soaking method: Soak the sterilized items in disinfectant, which is often used for household appliances that cannot or are inconvenient to cook. The soaking time varies with the nature of the article and solution. For example, it takes 1%-3% bleach solution to soak tableware and toilet 1 hour, 0.5% "84" disinfectant for 15 minutes, and 0.02% high-efficiency disinfectant for only 5 minutes to achieve the goal. If vomit and excrement are soaked, not only the concentration of disinfectant should be doubled, but also the soaking time should be doubled.
3. Fumigation method: use the gas generated by disinfectant to disinfect. It is often used to disinfect the air and the indoor surfaces of rooms where infectious diseases live. Formalin (formaldehyde)+potassium permanganate: 25-40ml of formalin and 0/5-30g of potassium permanganate/kloc are added to each cubic meter, and the two drugs are put together to generate gas, which can achieve the purpose of disinfection. Doors and windows must be closed during disinfection 12-24 hours, and ventilation should be turned on after disinfection. This method is effective for all kinds of infectious diseases caused by bacteria and viruses. Vinegar: 3- 10 ml of vinegar per cubic meter, 2-3 times of water for heating fumigation, used for indoor air disinfection, effective for preventing respiratory infectious diseases such as influenza.
