The first choice for cleaning and disinfection of the surface of environmental objects is disinfectant wipes, or wiping with a rag soaked in disinfectant solution, and spraying disinfection should not be adopted. The principle of cleaning and disinfection is to follow the principle of cleaning first and then disinfection, and adopt a wet and hygienic cleaning method. Choose the right cleaner based on the surface of the environment and the degree of contamination.
You can spray 75% alcohol on paper towels or cotton balls, wipe mobile phones and other easy-to-wear items, and air dry them naturally. When there is an open flame, do not spray alcohol. Disinfection of tableware with disinfection cupboards and boiling water are all possible.
Iodophor and iodophor alcohol compound formula products are used for skin disinfection, but alcohol cannot be used to disinfect mucous membranes.
Surface disinfection:
It is the simplest and most effective method of disinfection, which can be carried out without special equipment, and is the simplest and most effective method of disinfection, which can be carried out without special equipment. It has a good effect on killing reproductive bacteria and viruses, and has little effect on spores. The boiling time is generally 10-30 minutes.
Metal instruments, cotton fabrics, tableware, glass products, etc. can be boiled and sterilized. However, fur, woolen wool and plastic products cannot be boiled and sterilized. The boiling method is not suitable for disinfection of spore contamination.

There are four commonly used disinfectants: chlorine-containing disinfectant, alcohol-based disinfectant, phenolic disinfectant, physical disinfectant, etc. It is recommended that physical disinfectant sprays be preferred to disinfect environmental surfaces.
1.Chlorine-containing disinfectant: the main representative product is 84 disinfectant, which is mainly used for disinfection in medical and health care and public places, and the advantages are that it is cheap, not volatile, long-lasting sterilization, and has strong virus inactivation ability.
2.Alcohol disinfectant: the main representative product is ethanol, when the effective concentration is more than 75%, it can kill viruses or bacteria, and 75% alcohol is mainly used for disinfection of the surface of objects.
3.Phenolic disinfectant: The main representative product is chloro-m-xylenol, which is a broad-spectrum antifungal antibacterial agent, which has the effect of killing most bacteria and viruses, and is mostly used in the disinfection of clothing and clothing.
4.Physical disinfectant: the main representative products are material net, material net plus, mainly using physical principles to sanitize germs and pests, completely harmless to the human body and the environment, suitable for pregnant and infant families, pet families, mostly used in the disinfection of object surfaces.

1. The methods that can be used for disinfection of the surface of objects are:
spraying of chemical disinfectants;
chemical disinfectant wipes;
Ultraviolet radiation.
2. Disinfection of indoor air:The first choice is to strengthen ventilation and keep indoor air fresh;
spraying of chemical disinfectants;
Ultraviolet radiation.
Install an air sanitizer.
Precautions. The same disinfection method often has different effects on items of different natures. For the wall with smooth paint, it is not easy to stay by spraying the liquid, so it is advisable to rinse and wipe it. For rough walls, it is easy to make the liquid stay and can be sprayed for disinfection.
Ethylene oxide fumigation has a better effect on cloth and paper that are easy to absorb drugs, while it must be extended for metal surfaces.
Fecal and sputum disinfection should not be treated with coagulation protein drugs, because protein coagulation can play a protective role in pathogens, and although the high-pressure steam sterilization effect is good, it should not be used for fur, plastic and man-made fiber products.
Ethylene oxide fumigation of celluloid products, high-concentration peracetic acid or chlorine-containing disinfectants such as bleaching powder soaked cotton fabrics, and long-term soaking of latex gloves with lysosaurus liquid can cause damage. For food and tableware, it is not suitable to use toxic or foul-smelling disinfectants.

Disinfection is one of the important measures to cut off the spread of pathogens, and the disinfection products used should meet the management requirements of the national health departmentThe surface disinfection of environmental objects can be wiped with disinfectants containing chlorine (bromine), chlorine dioxide, peracetic acid, hydrogen peroxide and other disinfectants.
Indoor air disinfection can be sprayed with disinfectants such as peracetic acid, chlorine dioxide, and hydrogen peroxide. Hand disinfection is recommended to use a quick-drying hand sanitizer for wipe disinfection, and disinfectants such as iodophor and hydrogen peroxide can also be selected.
Basic principles of preventive disinfection of the public1. The family is mainly based on daily cleaning, supplemented by preventive disinfection.
2. Do not carry out large-scale disinfection of the outdoor environment, and do not carry out air disinfection of the external environment.
3. Do not directly use disinfectants to disinfect people.
4. Do not use high-concentration disinfectants for preventive disinfection.
5. Do not add disinfectants to ponds, reservoirs and other environments.
6. Strictly follow the instructions of disinfection products, and it is strictly forbidden to use beyond the range.

Summary. 1. The ground should be wet mopping, sprayed with 1000mg l chlorine disinfectant or peracetic acid for 30 minutes, and then mopped, 2 times a day. Disinfect at any time in case of contamination.
1. Wet mopping should be done on the floor of Douyin, and 1000mg l chlorine-containing disinfectant or peracetic acid should be sprayed for 30 minutes before mopping, 2 times a day. In case of contamination, Sun pretends to be disinfected at any time.
2. Tables, chairs, chains with window sills, cabinets, doors (handles), bedheads, cars, etc., should be wiped and disinfected with 1000mg L chlorine-containing disinfectant, twice a day. In case of failure, it means that the contamination is disinfected at any time.
3. Disinfection of other items: auscultation of Lu Zen device, sphygmomanometer, thermometer and other items, one person with one disinfection, the thermometer is soaked in 75% alcohol for 30 minutes and then taken out to dry the morning sun dust for later use, and the stethoscope and sphygmomanometer are wiped twice with 1000mg L chlorine-containing disinfectant. Disinfect at any time in case of contamination.
2. Indoor air disinfection method: open windows for ventilation at least twice a day, and irradiate ultraviolet lamps twice for one hour each time.
3. Medical waste disinfection methods: medical waste generated in ordinary fever clinics, pre-inspection and triage polluted areas, before leaving the polluted area, the surface of the packaging bag should be sprayed and disinfected with 1000mg l of chlorine-containing disinfectant (pay attention to spraying evenly) or add a layer of medical waste packaging bags outside it, and the medical waste should be stored in a separate area for temporary storage, and the sail should be handed over to the medical waste disposal unit for disposal as soon as possible. Disinfect the floor of the clinical waste temporary storage site with 1000mg l of chlorine-containing disinfectant, twice a day in the morning. Clean and disinfect the delivery tools with 1000mg l of chlorine disinfectant at the end of each day.

The division of the working area of the disinfection center generally includes the following areas:
1. Receiving area: It mainly refers to the area where the center receives raw materials, instruments and equipment, which needs to be kept clean and tidy to avoid pollution.
2. Washing area: It is mainly the area for cleaning and disinfection of instruments, and corresponding equipment and tools need to be set up to ensure that the instruments can be thoroughly cleaned and disinfected.
3. Packaging area: The first gear is mainly the area for packaging and sealing the sterilized equipment, which needs to ensure the hygiene and stability of the packaging materials and avoid secondary pollution.
4. Storage area: It is mainly the area where sterilized instruments and materials are stored, which needs to be classified and stored according to different categories to ensure the dryness, ventilation and safety of the storage environment.
5. Management area: It is mainly used to manage and record the relevant information of the disinfection center sock key, which needs to be equipped with corresponding office equipment and tools, so that the management personnel can view and update the relevant data at any time.
The clean area and the clean area are two important areas inside the disinfection center, and their specific areas are as follows:
1. Clean area: It is mainly an area for instrument disinfection, which needs to maintain a high hygiene standard, usually including a cleaning area, a disinfection area and a packaging area.
2. Cleaning area: It is mainly used for pretreatment preparations before cleaning and disinfection of instruments, which needs to be kept relatively clean and tidy, usually including receiving area and cleaning area.
In the workflow of the disinfection center, the clean area and the clean area are two key links. Only the efficiency and standardization of these two areas can ensure the quality and safety of instrument disinfection.

The main alcohol disinfectants on the market The advantages of alcohol disinfectants make them easy to use, safe, fast and volatile, but the disadvantage is the high cost of use, and the disadvantage is the high cost of use. The main products are ethanol, hexanhydrol, etc., which are mainly used in food processing, disinfection of process utensils, instruments, hands and other surfaces in the medical industry.
4. Alcohol disinfectant
What conditions should an ideal chemical disinfectant have The ideal chemical disinfectant should have the following conditions: sterilization and broad-spectrum; Low concentration of use; Fast rate of action; Stable in nature; Soluble in water; Can be used at low temperatures; It is not susceptible to the influence of organic matter, acid, alkali and other physical and chemical factors; No corrosion to items; It is colorless and odorless, and it is easy to remove residual drugs after disinfection.
Non-toxic or low toxicity, not easy to burn**, non-dangerous to use; **Inexpensive; It is easy to transport and can be supplied in large quantities. A disinfectant that meets all the requirements has not yet been found, and chlorine dioxide is the most desirable disinfectant comparatively.
Compared with solids and liquids, liquids have a prominent macroscopic characteristic that they do not have a certain shape and have fluidity. However, it has a certain volume and is not easy to compress, which is relatively close to solid in this regard. From a microscopic point of view, the molecules inside the liquid are also densely packed, the molecular spacing is small, and the intermolecular interaction force is large. >>>More
