How to disinfect going out and at home during the epidemic?

During the pandemic, it is crucial to do a good job of disinfection. Scientific disinfection is an effective means to cut off the transmission route of the new crown virus.

Here is a disinfection guide compiled by the "International Finance News" reporter for you.

Which disinfectant can I choose?

First of all, we should be clear that the spread of the new crown virus is mainly transmitted through droplet transmission and aerosol transmission. Therefore, when choosing disinfection products, we must choose sanitary disinfectants that meet the medical grade, no matter which new coronavirus variant strain is inactivated, it is effective.

According to the contents of the diagnosis and treatment plan for novel coronavirus pneumonia (trial ninth edition), it is mentioned that the following effective methods or preparations are mentioned: 30 minutes at 56 ° C, ether, 75% ethanol (alcohol), chlorine-containing disinfectants (84 disinfectants), peracetic acid (acetic acid) and chloroform (chloroform (chloroform) and other lipid solvents can effectively inactivate the virus, it should be noted that chlorhexidine (chlorhexidine) can not effectively inactivate the virus.

In addition, the disinfection products purchased through formal channels mainly depend on whether the outer packaging is marked with the "disinfection product hygiene license number". Such disinfection products can achieve results by following the instructions for use.

How to use disinfectant preparations rationally?

When disinfecting, it is necessary to use disinfectants reasonably and safely, and hand disinfection can choose alcohols or quaternary ammonium salts; surface wipes and disinfection can be used directly, or chlorine-containing disinfectants, quaternary ammonium salt disinfectants, etc. can be selected. When using chemical disinfection products, personal protection is required, and when using alcohol at home, it is necessary to pay attention to the risk of fire prevention and explosion.

How to use the common drip disinfectant on the market: a bottle of cap drip disinfectant + 400ml.

In the home, 84 disinfectant and medical alcohol are the two most commonly used disinfectants in the home. 84 disinfectant is a chlorine-containing disinfectant, which is corrosive and irritating to the skin and mucous membranes, and cannot be directly touched by hand, and gloves must be worn when preparing and using.

It should be noted that 84 disinfectant cannot be mixed with other cleaning agents. 84 Disinfectant is mixed with toilet cleaner, which will generate chlorine gas and cause harm to the body. After disinfection is completed, rinse with clean water to remove the residue of disinfectant.

Medical alcohol should be stored in a cool, dry, ventilated place away from light and out of reach of children. Due to the flammability of alcohol, it is necessary to keep away from the source of fire when using, spray disinfection is prohibited indoors, and it should be disinfected by wiping method.

How to disinfect your home?

If there is no suspected or confirmed patient in the home, the home is cleaned daily and does not need to be disinfected; for families with suspected or confirmed patients, people who must stay at home for a short time need to clean and disinfect the home place every day; when suspected or confirmed patients are found, the home place should be disinfected in an all-round way.

In addition, as everyone spends more time at home, we must pay more attention to the disinfection of the home environment.

1. How to disinfect the air?

The first is air disinfection. Prefer natural ventilation, as far as possible to open the doors and windows ventilation, it is best to continue to open the window, if not possible, at least 2-3 times a day ventilation, each time not less than 30 minutes. Families with conditions can also use circulating air disinfectants, air conditioning filters, filters, should be cleaned and disinfected every month, and can be sprayed with air conditioning disinfectant until moist, acting for 30 minutes.

The question is, will the window ventilation virus enter the home?

The spread of the new crown virus is mainly through droplet transmission and aerosol transmission. Droplets generally do not travel more than two meters to spread the new coronavirus, and then fall and do not drift with the wind.

Although natural ventilation carries the risk of air cross-flow, the concentration of polluted air is often low enough to reach the concentration of conditions transmitted through aerosols.

Therefore, increasing the amount of ventilation can effectively reduce the risk of airborne transmission of infectious diseases, so the daily opening of more windows and ventilation can effectively prevent the spread of infectious diseases, if the air quality is good, the weather allows, the room should be ventilated two or three times a day, each time not less than 30 minutes, so that not only to prevent the new crown virus from entering, but also to reduce the possible concentration of viruses in the room.

It should be noted that residents of the same building as the confirmed case should also pay attention to the ventilation of the corridor.

2. How to disinfect the large and small items at home?

In fact, most of the items in the home do not need to be disinfected, but for frequent use and contact with the surface can be disinfected. Small items such as mobile phones, mice, door handles, faucets, various buttons, etc., can be wiped and disinfected with 60-80% alcohol cotton balls or disinfectant wipes; large areas such as desktops, the ground, can be sprayed, wiped or dragged disinfectant containing effective chlorine (bromine) 500 mg /L; clothing, bedding and other fabrics generally do not need special disinfection, but to change and wash frequently, dry frequently, can be exposed to the sun for 4-6 hours; dining utensils are generally cleaned with "detergent + running water", if not assured, Boiling or using a disinfection cabinet is also a good choice.

It is worth noting that home disinfection should also avoid excessive, do not let "disinfection" become "poisoning". The concentration of disinfectant is not as high as possible, and excessive disinfection will not only not increase the disinfection effect, but will bring negative effects to our health.

How to disinfect when going out and going home?

1. Can I take the elevator when I go out?

The space in the elevator is small and closed, and many elevators can only supply air through the top air volume fan, and the ventilation effect is poor, and it is very easy to deposit viruses and bacteria. Moreover, the buttons of the elevator belong to the high-contact surface, and if the buttons with viruses are touched, it is possible to cause infection due to eating, touching the nasal cavity, and the conjunctiva of the eyes.

Elevators are indeed a high incidence of contact transmission areas, if used by new crown pneumonia patients, the surface may indeed be stained with new coronavirus, but this is not to say that we can not take the elevator, but to wear a mask, stagger the peak, to avoid touching the various surfaces inside the elevator.

If you must touch, it is best to isolate with tissues and gloves, do not let your hands touch directly, do not touch your eyes, nose and mouth with your hands in the elevator, and wash your hands immediately after returning home.

If you can take the elevator alone, it is best, if you can't, it is best to stand facing the wall in the elevator to reduce the transmission. But don't forget that you can also take the stairs.

2. How to disinfect when going out and going home?

The new crown virus is mainly transmitted by droplets and aerosols, so the virus in the air falls on the ground.

If you go out to do nucleic acid or take a courier, you can choose to put on a shoe cover or a plastic bag, and then disinfect the shoe cover plastic bag after returning home.

3. How to disinfect the courier or materials?

About courier disinfection. Express delivery as far as possible in the outdoors to dismantle, the outer packaging should not be taken home, according to the classification of domestic garbage.

When going to express delivery or supplies, you can choose disposable gloves, put disinfectant water at the door, and the hand-held part is easy to carry the virus, so it is necessary to disinfect it thoroughly.

After spraying the outer packaging, leave it outdoors for 5-10 minutes to disinfect, and food with independent packaging should also disinfect it. (Try to buy melons and fruits with skins, fruits such as strawberries or grapes that are directly imported are not easy to disinfect)

Before entering the door, the sole or shoe cover should be disinfected, and the clothes worn outside can be dried on the balcony.

If you need to take it home and dismantle it, you can wear a mask and disposable gloves, use disinfectant wipes to completely wipe the surface of the outer packaging to disinfect, let the disinfection factor work for half an hour, and disinfect the hands after processing the courier.

4. Is it infected to go out and throw away garbage?

It is true that the garbage used or discarded by patients may carry the new coronavirus, but the probability of transmission to others is unlikely. In the community where the diagnosis occurs, the staff who handle the garbage and remove the garbage will generally wear protective clothing and take protective measures, and others will generally not be directly exposed to it, and the risk is very small.

When throwing garbage, wear a mask at the same time, do not directly touch the garbage can, it is best to wear disposable gloves to lift the lid of the garbage can, and wash your hands thoroughly after returning home.
