most modern people have a high awareness of health and safety, and they also pay great attention to the cleanliness of their homes. All kinds of disinfectants are very popular among the masses. Some people always feel that nothing is clean enough, and they always want to use disinfectant to clean it completely before they feel that it really meets the hygiene standards. But is this true? Then, what harm will excessive disinfection of disinfectant cause? What are the precautions for disinfection with disinfectant?

1. Harm of excessive disinfection

Actually, if the disinfectant is not completely removed, the human body will ingest the residual disinfectant through respiratory inhalation, oral ingestion 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.

Family environmental hygiene is mainly based on cleanliness, and the 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 a possibility of infection. At this time, disinfectants can be used for disinfection to prevent the spread of diseases.

the blind area of household cleaning

1. The rubber sealing strip of kitchen refrigerator and the handle of kitchen utensils, including pots, shovels and spoons. 2. The washbasin, bath pool, faucet, various handles, floor, toilet seat cushion, foot pad, trash can, toilet utensils, etc. 3. Remote control of TV in living room and bedroom, filter of air conditioner, etc.

Common hygienic misunderstandings

1. Towels are hung in the bathroom. It is best not to hang towels in the bathroom. After use, wring them out in time and dry them in a ventilated and dry place to avoid bacteria breeding caused by humidity.

2. Habitually placing a wastebasket next to the toilet will only increase the chances of bacterial reproduction. For sanitary articles that are difficult to be washed 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, change clothes and disinfectant in the bathroom. In fact, high-temperature and humid environment is the most vulnerable to pathogenic bacteria, and commonly used sanitary products are best placed at any time, or in a ventilated special storage cabinet.

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 disinfected by high-temperature steam or boiled in boiling water for 21 ~ 31 minutes. Daily necessities can be disinfected by ultraviolet radiation from the sun.

2. Pay attention to the use of disinfectant

1. Under normal circumstances, families only need to be clean and hygienic, and there is no need for disinfection; Disinfection is necessary when there are patients at home, especially those with infectious diseases, or after outsiders visit.

2. For ordinary families, physical disinfection methods, such as cooking and sun exposure, should be chosen as far as possible when choosing disinfection methods. Boiling disinfection or disinfection cabinet should be preferred for tableware disinfection. Clothing and bedding are mainly exposed in 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 running water.

3. Disinfect the surfaces of frequently contacted objects, such as door handles, stair handrails, foot pads, faucets and other key parts. Do not spray disinfectants all over the house.

4. For washbasins and toilets, it is only necessary to spray a proper amount of disinfection on the surfaces, and then rinse them with a large amount of tap water, otherwise it will corrode the pipe network; Floor drains and sewers should not be specially disinfected with disinfectant, because disinfection of floor drains or sewers usually fails to achieve the purpose of disinfection and disease prevention, and will also corrode the pipe network and bring future troubles.

5. Don't neglect the disinfection of key items, such as dish cloths. Because of frequent use, they are often in a wet state, and there are many organic substances such as food, which is very conducive to the growth of bacteria. Therefore, they should be exposed to the sun and boiled frequently for disinfection.

6. The pet's nest should be disinfected frequently.

Usage principle of household disinfectant:

1. Reasonable concentration: Chemical disinfectant can only achieve disinfection effect if it reaches a certain concentration. If the concentration is too low, it can't eliminate pathogenic microorganisms. If the concentration is too high, it may have obvious destructive effect on disinfection objects and may bring harm to human health. The higher the concentration of disinfectant, the better.

2. Strictly stipulate the time: Disinfectants can only have disinfection effect if they act for a certain time. Some disinfectants can sterilize quickly, while others can sterilize slowly. Different disinfectants and different disinfection objects may need different action time. To ensure effective disinfection, disinfectants and disinfection objects must act for a certain time.

3. Ensure safe use: At present, most chemical disinfectants on the market are harmful to people and articles, so attention should be paid to safety when using them. Avoid direct contact of disinfectant with human body. If it accidentally spills into eyes, it should be washed immediately with clear water. For the sake of safety, 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 object to be disinfected should be cleaned as much as possible, and it is best to clean tableware and furniture before disinfection. Because the moisture on the disinfected articles may reduce the concentration of disinfectant, the disinfected object should be relatively dry during disinfection.

5. Chemical disinfectants are now used: most chemical disinfectants are unstable, especially after being diluted with water, they are easier to decompose, so they must be used now and cannot be reused; Repeated use will cause disinfection solution pollution and reduce disinfection effect.

6. Scientific disinfection: Different disinfectants have different effects on killing pathogenic microorganisms, and different microorganisms have different resistance to disinfectants. General household disinfectants only kill some common microorganisms, but may not have disinfection effect on some microorganisms with strong resistance. Therefore, if there are infectious patients in the family, disinfection measures should be taken according to the doctor's advice and the requirements of the local disease prevention and control department.

Precautions for using household disinfectant:

1. If there are infants, pregnant women, the elderly and other immunocompromised people or patients in the family, use disinfectant with caution. If there are no patients with infectious diseases, it is best not to disinfect with disinfectant.

2. Avoid using disinfectant in wine bottles and beverage bottles to avoid misuse. Don't replace the bottle with a beverage bottle to prevent adults or children from being poisoned by drinking it by mistake. If you use other bottles, be sure to indicate the word "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 operate in strict accordance with the concentration, dosage and disinfection time of disinfectant.

4. Take certain protection (gloves, glasses, etc.) during application, and do not touch the stock solution directly with your hands. Everything that has been soaked with disinfectant must finally be cleaned to remove the residue.

5. Generally, window ventilation can be used for air disinfection. If there are special requirements, disinfectant spray or ultraviolet rays must be used for direct irradiation, 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 should not enter until the smell is exhausted.

7. If skin or other parts of the body are allergic to disinfectants and have allergic symptoms during disinfection, you should stop using this disinfectant and use antiallergic drugs as appropriate under the guidance of doctors.

The above is the introduction of the usage and precautions of disinfectant. I hope that through the introduction of this article, everyone will have a certain understanding of the usage of disinfectant and some unnecessary safety common sense, and safe and reasonable disinfection can bring health to their families.
