Disinfection tips during COVID-19

Disinfection is one of the most effective ways to block the transmission of viruses. However, family protection should focus on cleaning, supplemented by disinfection.

 

1.Do not spray alcohol indoors for disinfection.

When using alcohol indoors, spraying disinfection should be avoided. Besides, to disinfect the surface of electrical appliances, turn off the power supply first and wait for the electrical appliances to cool down, otherwise the cleaning may cause explosion or fire.

 

2.Take necessary protection when using disinfectants.

When using disinfectants, avoid touching your mouth and nose. It is best to wear masks and rubber gloves to prevent ingestion of splashing liquids.

 

3.The concentration of disinfectants should not be too high or too low.

The disinfectants sold in the market should be diluted before use, and choose 75% alcohol by volume for disinfection.

 

4.Do not over disinfect.

There is no need to disinfect if the surroundings are not polluted by vomit, secretion and excreta.

 

5.Disinfectants cannot be mixed.

When two or more disinfectants are mixed, it is easy to produce a chemical reaction and may cause injury. Laundry detergent should not be mixed with disinfectants.

 

Chlorine produced by the mixture of 84-disinfectant and alcohol will damage the respiratory tract. When the concentration of chlorine reaches 3,000 mg / m3, it can cause death. The mixture of 84-disinfectant and toilet cleaners will produce a toxic gas, which will irritate the human throat, respiratory tract and lungs and cause poisoning.

 

1.Don’t carry out outdoor disinfection in rainy and snowy weather.

 

2.Don’t use glutaraldehyde for outdoor disinfection or to disinfect with spray air.

 

3.Don’t put disinfectant powder into lakes and ponds.

 

1.If there are no COVID-19 cases in the community, no visitors, and no suspected COVID-19 cases, then focus on daily cleaning without carrying out daily disinfection.

 

2.It is recommended to maintain good ventilation and a clean environment, and wash hands immediately after arriving home. Waterless hand sanitizers contain bactericidal ingredients (mainly alcohol) and have a disinfection effect. However, disinfection ingredients often cause irritation, which may lead to allergic skin reactions.

 

If possible, wash hands with running water, use soaps or hand sanitizers, and carefully clean fingertips, palms and wrists.

 

3.When using chemical disinfection products, pay attention to personal protection during dilution. 

 

4.When cleaning mobile phones and other electronic products with disinfected wipes, turn them off and wait for them to cool down completely to avoid fire or explosion caused by static electricity.

 

5.Coats should be disinfected after going to the hospital, visiting patients, or being in close contact with suspected cases. Boiling is the preferred method for disinfection. For cloth that cannot withstand high temperature, disinfectants containing chlorine can be used for immersion disinfection.

 

6.For the disinfection of tableware, boiling them for ten minutes is recommended.

 

7.Package wrappings are better not brought into the room. When it is necessary to bring them in, disinfectant wipes can be used to clean them. 

 

1.Disinfect delivery tools.

Delivery boxes for takeout should be kept clean and disinfected, and scattering of meals should be avoided.

The closed box, brake handle, handrail and other frequently contacted parts of delivery vehicles should be disinfected. These parts can be wiped with disinfectants containing chlorine (effective chlorine of 500mg / L), and then cleaned with water after 30 minutes.

 

2.Wash work clothes and cleaning supplies soon after use and disinfect them regularly.
