Disinfection is one of the effective ways to block the spread of viruses, but unreasonable disinfection methods not only fail to kill the virus, but may instead cause harm to the body or the environment. Therefore, in the process of using disinfectants at home, there are some misunderstandings, please pay attention.

No.01 Excessive disinfection and neglect of daily cleaning

Home protection should be based on cleaning, supplemented by disinfection, and do not over-disinfect due to panic. If there are no new crown cases in the community, no outsiders visit at home, and no self-isolated suspected symptoms, then there is no need to disinfect every day. It is recommended to keep the home ventilated and the environment clean, and wash hands as soon as possible after going out. When the environment outside the community is not clearly contaminated by vomit, secretions or excreta, disinfection is not required in principle. The exterior of vehicles entering and leaving the community does not need to be disinfected.

No.02 Disinfectant concentration is too high or too low

Some people think that the higher the concentration of disinfectant, the better the effect of disinfection and sterilization, but this is not the case. Strong disinfectants are generally very irritating, and if the concentration is too high, they may irritate people's mouth, respiratory tract, lungs, etc., and even risk organ and tissue damage. Commercially available disinfectants should be diluted according to the instructions and labels before use, and alcohol should be used for disinfection at a concentration of 75%.

No.03 Mixed use of different types of disinfectants

Mixed use of two or more disinfectants can easily cause chemical reactions and may cause harm. 84 The chlorine gas produced by mixing disinfectant and alcohol will stimulate and damage the respiratory tract. When the concentration reaches 3000 mg/m3, it can cause death. 84 Disinfectant mixed with toilet cleaning agent will produce toxic gas, which will stimulate the throat, respiratory tract and lungs of the human body and cause poisoning. Laundry detergent should also not be mixed with disinfectants.

No.04 Necessary protection when using disinfectants

Disinfectants are generally highly irritating and may cause respiratory and skin damage. In the process of using disinfectant, pay attention to avoid the nose and mouth, and it is best to wear a mask and rubber gloves to prevent liquid splashing.

No.05 Indoor spraying alcohol for disinfection

When using alcohol indoors, avoid spray disinfection. To disinfect the surface of electrical appliances, turn off the power first and wait for the electrical appliances to cool before proceeding, otherwise it may cause deflagration.

No.06 Use hand sanitizer instead of running water to wash hands

The hand sanitizer contains bactericidal ingredients (mainly alcohol), which has a certain disinfection effect. However, the disinfectant ingredients are often irritating and may cause allergic skin reactions. Therefore, if possible, wash your hands with running water as much as possible, use soap or hand sanitizer, and carefully clean all parts of your fingertips, palms, and wrists.

No.07 No follow-up cleaning after items are disinfected

Disinfectants have a corrosive effect on items, especially metals, and are also irritating to the human body. After using the disinfectant for half an hour, clean the environmental surface with clean water.

No.08 Unreasonable storage of disinfectants

Most chemical disinfectants are flammable, explosive, and corrosive items, and attention should be paid to safety during storage and use. Do not buy too much disinfectant each time. Containers for disinfectant must have closed lids. A single bottle should not exceed 500 ml. It should be placed in a cool place protected from light and heat to ensure that it is not easy for children to reach. The rags or other items used for disinfection should be washed with plenty of water after use, and then air-dried in a ventilated place.
