How to disinfect hotel rooms?

(1) disinfection methods for tea sets and wine sets:

① Physical disinfection method:

A. high-temperature disinfection:

High temperature disinfection can be divided into boiling disinfection and steam disinfection. The principle is that at high temperature, protein in bacteria will condense, leading to its death. .

Boiling disinfection is a disinfection method in which the washed tea set is boiled in boiling water at 100 degree for 15~30 minutes. This method is suitable for porcelain, but not for glassware.

Steam disinfection is a disinfection method in which washed tea sets or wine sets are put into an air box and steamed for 15 minutes. This method is suitable for disinfection of various tea sets, wine sets and tableware.

B. dry baking method:

Dry baking is a disinfection method that destroys the protoplasm of microbial cells by oxidation and makes them die. At present, the disinfection cabinets commonly used in guest rooms are mostly of this type, and infrared radiation sterilization is used for disinfection. Put the washed tea set into the disinfection cabinet, then adjust the temperature to 120 degrees and dry bake for 30 minutes.

② Chemical disinfection method:

Chemical disinfection can denature protein in microorganisms, interfere with their metabolism, inhibit their rapid reproduction and dissolve bacteria. The commonly used chemical disinfection method is immersion disinfection, which must be dissolved first and prepared in strict proportion to be effective. If the concentration is too high, it is easy to leave toxic substances, which is harmful to human body; If the concentration is too low, the purpose of disinfection will not be achieved. The operation method is: soak the washed cups in disinfectant for 5 minutes in batches, then rinse them with clear water and dry them.

Commonly used chemical disinfectant solutions are as follows:

A. chloramine t sodium. It is suitable for disinfection of various cups and utensils in guest rooms, and has fading and corrosive effects on metal utensils.

B. bleaching powder. The concentration of the preparation is 3%, and it can be used after being stirred evenly. Suitable for cups, fruits and cotton products.

Disinfect.

C. potassium permanganate. The configuration concentration is 0.5%. , can be used for disinfection of various cups and fruits, and the soaking time is at least 5 minutes.

D "84" disinfectant: a disinfectant with high efficiency, non-toxicity and strong decontamination ability. Can quickly kill hepatitis A, hepatitis B virus, AIDS virus, etc. The concentration is 0.2% or 0.5%, which is suitable for disinfection of tea sets, wine sets, furniture and fruits.

(2) room disinfection:

① Wipe the equipment and furniture in the guest room with drug aqueous solution to achieve the purpose of disinfection. Chemical disinfectant can be used for wiping and disinfection.

② Ventilation can not only change the indoor air environment, but also prevent the breeding of germs and mites. Therefore, attention should be paid to improving the ventilation and air conditioning effect of the room to maintain a good air environment. Pay attention to changing the filter membrane of air conditioner regularly.

③ Outdoor sunlight disinfection: ultraviolet rays in sunlight can kill some germs. Therefore, turning over mattresses, bedspreads and quilts regularly can not only disinfect, but also make them soft and comfortable.

(3) toilet disinfection:

① Spray disinfection method. Chemical disinfectant can be used for disinfection, such as spraying bleaching powder clarification solution or phenol solution with the concentration of 1%~5% in the dead corner of the bathroom or bathroom. However, it should be noted that bleaching powder and acid cleaner should not be used at the same time to avoid chlorine poisoning. It is best to spray a quick-drying disinfectant.

② Ultraviolet disinfection method. This method can be used for air disinfection in toilets as long as an ultraviolet lamp with a power of 30 watts is installed.

A tube, the lamp is about 2.5m from the ground, and each time it is irradiated for 2 hours, the microorganisms in the air can be reduced by 50%-75%, sometimes exceeding 90%.
