After three years of trials from the epidemic, everyone has a certain understanding of cleaning and disinfecting the home environment, but there are also many questions in when using disinfectants. Have you encountered the following problems during the home disinfection process?
Q
When you are in contact with many people and things outside, do you need to spray and disinfect your whole body before going home?
Never spray disinfectant on the human body! The possibility of the human body and outerwear carrying the new coronavirus is very small, and even a small amount of pollution is not enough to cause transmission. Disinfectants are harmful to the human body and can be inhaled into the lungs during spraying, causing lung damage. By spraying, it is difficult to achieve disinfection concentration and the disinfection effect cannot be achieved.
Q
The new coronavirus can be transmitted through aerosol . Can it be sprayed with a large amount of disinfectant indoors for disinfection?
Don't spray a lot of disinfectant in the room at will. Chemical disinfectant cannot be air-disinfected when there are people indoors. Especially spraying alcohol can easily cause fires. The best way to disinfect the air is to open the windows and ventilate naturally. It is recommended to open the windows at least twice a day for more than 30 minutes each time.
Q
Disin your home every day, and as a result, the furniture and floor are corroded and oxidized by disinfectants. What should I do?
People who do not have suspicious symptoms of new crown or other infectious diseases in the family, or when the surrounding areas are in a low epidemic state, just do daily cleaning, and there is no need for preventive disinfection of . In most cases, cleaning is enough to reduce the risk.
Q
Always worried that disinfection is not done enough. Can you use multiple disinfectants in one overlay?
Unless required by the product instructions, do not mix disinfectants at will with , otherwise will cause harm to the human body. Use regular disinfection products, use them according to the instructions, and use one disinfectant at a time.
Q
I wore gloves when I went out. Can I stop washing my hands when I come back?
Wearing gloves cannot replace hand hygiene. Wearing gloves can reduce contact contamination, but after returning, you still need to use running water and soap, or use hand sanitizer to clean and disinfect your hands. Can all wet wipes be used for disinfection?
First of all, you need to pay attention to the ingredients of the wet wipes. If contains alcohol , effective chlorine, hydrogen peroxide and other disinfection ingredients , it can be used as disinfection. If it is a wet wipe that mainly consists of purified water , it will only have a cleaning effect.
Q
How to protect special groups when using disinfectants?
For families with alcohol allergies people with , try to avoid using alcohol disinfection as much as possible, otherwise it may cause allergic reactions. For asthma patients with , disinfectants may cause asthma attacks. When using disinfection products, try to stay away and open windows for ventilation. Keep the disinfectant away from infants and young children , so you don’t need to ask the children to participate in family disinfection work together.
Q
When using disinfectant effervescent tablets to configure disinfectant, you have coughing and can't open your eyes. What should you do?
Disinfection effervescent tablets are low-priced and can be used to disinfect the surface of large-area environmental objects. There will be some irritation when configuring, so you should pay attention to choosing to configure in a well-ventilated environment, wear a mask and gloves, and try to avoid irritation to the respiratory tract and eyes. In addition, I would like to remind everyone that as the disinfectant evaporates, the concentration will gradually decrease, so you should use it and dispense it immediately; according to the different disinfection needs, configure it according to the ratio of the instructions; do not use hot water to configure it quickly, as it will not reach the concentration required for disinfection; if necessary, after the disinfectant is fully effective, you can wipe it with a clean water rag to remove the residual disinfectant.
Q
I heard that sewers can also spread virus . Can disinfection tablets be thrown directly into the sewers?
If there are positive people in the building, we also need to pay attention to the sewer entrances in the bathroom, kitchen, balcony, etc. of our home.For those with U-type tube , ensuring sufficient water storage for U-type tubes and forming a U-type tube water seal can effectively prevent the aerosol from spreading . For bath tub drains that are not often used or floor drains without water seals, you can use tape to completely seal them, or use sealed plastic bags to fill them tightly and seal them. Never throw disinfection tablets directly into the sewer, as high concentration of disinfectant will corrode the sewer.
Q
The long-awaited takeaway or express delivery has finally arrived. How to collect it safely?
Takeout or express delivery has passed many hands before delivery. Please suppress your excitement first and use disinfectant wipes to wipe the outer packaging of , especially the position of the hand. Try to unpack the takeaway or express delivery at your doorstep, and don’t take the outer packaging back home. After disinfection, your hands must be cleaned again.
