1, the hazards of excessive disinfection
In fact, if the disinfectant is not completely removed, the human body will ingest the residual disinfectant through respiratory inhalation, oral administration and skin contact, which is harmful to health. Long-term abuse of disinfectants will also cause drug resistance of pathogenic microorganisms in the environment, promote the growth of pathogenic bacteria and reduce the disinfection effect of disinfectants. Different chemical reagents have different disinfection principles, and chemical reactions may occur after mixing, which may cause danger in serious cases.
Household environmental sanitation is mainly based on cleanliness, and routine use of disinfectants is not recommended. If there are patients with infectious diseases such as hepatitis living at home, or there are articles and floors contaminated by blood, body fluids, secretions and excreta of patients with infectious diseases, there is the possibility of infection. At this time, disinfectants can be used for disinfection to prevent the spread of diseases.
Blind spot of home cleaning
1. Rubber sealing strip of kitchen refrigerator and handles of kitchen utensils, including pots, shovels and spoons. 2. Washballs, baths, faucets, various handles, floors, toilet cushions, foot pads, trash cans, toilet utensils, etc. 3. TV remote control in living room and bedroom, air conditioning filtering, etc.
Common health misunderstandings
1. The towel is hanging in the bathroom. It is best not to hang towels in the bathroom. After use, wring it out in time and put it in a ventilated and dry place to dry, so as to avoid moisture breeding bacteria.
2. Habitually putting a wastepaper basket next to the toilet will only increase the chances of bacterial reproduction. For sanitary products that are difficult to wash away with water, you can bring your own small convenient bag and take it out of the bathroom at any time to throw it away.
3. Use the bathroom as a storage room, and put the mop, washbasin, clothes and disinfectant in the bathroom. In fact, high-temperature and humid environment is the easiest place to breed pathogenic bacteria. It is best to keep common sanitary products at any time, or put them in ventilated special lockers.
To keep the indoor environment clean, it is necessary to clean it frequently, leaving no dead ends and keeping it clean. Open more windows for ventilation to keep indoor air circulation. Tableware can be sterilized by high-temperature steam or boiled in boiling water for 20 ~ 30 minutes. Daily necessities can be disinfected by ultraviolet radiation from the sun.
2. Pay attention to the use of disinfectants
1, in general, as long as the family is clean and hygienic, there is no need for disinfection; Disinfection is necessary after there are patients at home, especially those with infectious diseases, or after outsiders visit.
2. For ordinary families, when choosing disinfection methods, we should try our best to choose physical disinfection methods, such as cooking and exposure. Tableware disinfection should first be boiled disinfection or disinfection cabinet disinfection. Clothing and bedding are mainly exposed to the sun. Indoor air disinfection mainly adopts regular window ventilation. When washing your hands, if you don't touch the patient, just use ordinary soap and tap water.
3. Disinfect key parts such as door handles, stair handrails, foot pads and faucets. Don't spray disinfectant on a large area of the whole house.
4. For washbasins and toilets, just spray a proper amount of disinfectant on the surface, and then rinse with a large amount of tap water, otherwise it will corrode the pipe network; Floor drains and sewers should not be specially disinfected with disinfectants, because the disinfection of floor drains or sewers usually fails to achieve the purpose of disinfection and disease prevention, and it will also corrode the pipe network and bring future troubles.
5, don't miss the disinfection of key items, such as rags, because of frequent use, often in a humid state, and more contact with food and other organic substances, which is very conducive to the growth of bacteria, so often expose to the sun and boil for disinfection.
6. The pet's nest should be disinfected frequently.

Principles for using household disinfectants:
1. reasonable concentration: chemical disinfectants can only achieve disinfection effect if they reach a certain concentration. If the concentration is too low, pathogenic microorganisms cannot be eliminated. If the concentration is too high, it may have obvious destructive effect on the disinfected object and may bring harm to human health. The higher the concentration of disinfectant, the better.
2. Strictly specify the time: Disinfectants only have disinfection effect after a certain period of time. Some disinfectants have a quick sterilization effect, while others have a slow sterilization effect. Different disinfectants and different disinfection objects may need different action time. In order to ensure effective disinfection, the disinfectant must act with the disinfection object for a certain period of time.
3. Ensure safe use: At present, most chemical disinfectants on the market are harmful to human body and articles, so attention should be paid to safety when using them. Avoid direct contact between disinfectant and human body. If it accidentally spills into eyes, it should be washed with clear water immediately. For safety reasons, gloves and glasses should be worn when preparing disinfectant to avoid the presence of children.
4. Reduce the influencing factors: the disinfection effect is related to the nature of the disinfection object, and articles containing organic matter may affect the disinfection effect. Before disinfection, the disinfected objects should be cleaned as much as possible, and it is best to clean tableware and furniture before disinfection. Because the moisture on the disinfected object may reduce the concentration of disinfectant, the disinfected object should be relatively dry during disinfection.
5. Now chemical disinfectants are ready-to-use: most chemical disinfectants are unstable, especially after being diluted with water, they are easier to decompose, so they must be used immediately and cannot be reused; Repeated use will cause disinfection solution pollution and reduce disinfection effect.
6. Scientific disinfection: Different disinfectants have different killing effects on pathogenic microorganisms, and different microorganisms have different resistance to disinfectants. General household disinfectants only kill some common microorganisms, and may have no disinfection effect on some highly resistant microorganisms. Therefore, if there are infectious patients at home, disinfection measures should be taken according to the doctor's advice and the requirements of local disease prevention and control departments.

Matters needing attention in the use of household disinfectants:
1, if there are infants, pregnant women, the elderly and other immunocompromised people or patients at home, use disinfectants with caution. If there are no patients with infectious diseases, it is best not to disinfect with disinfectant.
2. Avoid using disinfectants in wine bottles and beverage bottles to avoid misuse. Do not use beverage bottles instead of milk bottles to prevent adults or children from being poisoned by accidental drinking. If you use other bottles, be sure to mark "disinfectant". Disinfectants stored at home should be kept out of the reach of children or locked.
3. Choose and use chemical disinfectants correctly according to the instructions, read the product instructions carefully before use, and use them in strict accordance with the concentration, dosage and disinfection time of disinfectants.
4, in the process of pesticide application should have certain protection (gloves, glasses, etc. ) Don't touch the stock solution directly with your hands. Everything that has been soaked with disinfectant should be cleaned to remove the residue.
5. Air disinfection can generally choose to open the window for ventilation. If there are special requirements, it must be sprayed with disinfectant or directly irradiated by ultraviolet rays, and it must be carried out indoors without people, so as to reduce the harm to human body.
6. When using chemical disinfectants for spray disinfection, in order to ensure the disinfection effect, the doors and windows should be closed during disinfection, and the doors and windows should be opened for ventilation after disinfection, and the family can enter again after the smell is removed.
7. In the process of disinfection, if the skin or other parts of the body are allergic to the disinfectant and have allergic symptoms, you should stop using the disinfectant and use antiallergic drugs as appropriate under the guidance of a doctor.
The above is the introduction of the use method and matters needing attention of disinfectant. I hope that through the introduction of this article, we can have a certain understanding of the use of disinfectant and some unnecessary safety common sense. Safe and reasonable disinfection can bring health to our families.
