How long does alcohol wipe disinfect work, and how to use alcohol disinfection?

What do I need to pay attention to when disinfecting with alcohol?

To use alcohol disinfection, you must first understand its characteristics, and then master the correct method to use it with confidence.

Alcohol has flammable, explosive and volatile characteristics, for our ordinary family, personal and home protection does not necessarily have to use medical alcohol, but if alcohol disinfection is used, we must pay attention to the concentration of alcohol, among them, the alcohol concentration should reach 75%, if the concentration is 95% of the alcohol, it needs to be compared to 4 to 1, 4 parts of alcohol, 1 part of water ratio to 75% alcohol.

Dangerous characteristics of alcohol: alcohol is extremely flammable, gaseous alcohol and air can form a first-class mixture, and can cause combustion when exposed to open flame and high heat energy. Gaseous alcohol is heavier than air and can spread to a considerable distance at a low level, and will ignite and ignite when exposed to an ignition source.

A fire can occur when the concentration of ethanol in the air exceeds 3%. When alcohol is used in large quantities, alcohol volatilization increases the concentration of ethanol in the indoor air and is more dangerous than directly igniting the alcohol.

Using air disinfection, the home is first ventilated, followed by ultraviolet lamps and air purifiers, and it is not recommended to disinfect with alcohol first.

As the saying goes, it is good to use it on the blade, so when this alcohol is used for disinfection, where should it be used to achieve effective personal and household protection?

Alcohol disinfection is mainly used on some hard surfaces, such as glass, porcelain blocks, glasses, mobile phone surfaces, etc., which can be sprayed with alcohol for disinfection, and let stand after spraying, without wiping. In addition, objects that require high-frequency contact can also be disinfected with alcohol.

Precautions for using alcohol for disinfection.

1.When using alcohol indoors, wipe it with a cloth cleaning tool such as a towel, and after use, wash it with plenty of water and store it tightly closed, or put it in a ventilated place to dry.

2.It is not recommended to use alcohol to spray and disinfect clothing, etc., as it may burn in case of open flames or static electricity.

3.Store alcohol cautiously, away from fire, and out of reach of children.

4.When using alcohol, pay attention to ventilation, and stay away from high-temperature objects and do not come into contact with open flames. After spraying with high concentration of alcohol, you cannot immediately cook, snort, smoke, etc.

5.Before using alcohol, the surrounding flammable and combustible materials should be cleaned up, and the power and fire sources should be turned off when disinfecting the surface of electrical appliances and stoves, and then wiped with alcohol after the electrical appliances and stoves are cooled to avoid deflagration caused by alcohol volatilization.

Use alcohol properly.

Alcohol disinfection effect time Cleaning and sterilization is essential in our lives, and there are many benefits of regular cleaning of air conditioners, such as ensuring the use effect, good health, prolonging service life, saving costs, and so on. Today, I will explain to you the method of cleaning and sterilizing the air conditioner, let's take a look!

1. The benefits of cleaning air conditioners.

1. The benefits of cleaning the air conditioner - to ensure the use effect.

In hospitals, 75% alcohol is usually used to clean and disinfect **, such as injections and infusions. Therefore, this is the most commonly used way of alcohol application, and it is rarely used to spray alcohol for disinfection in clinical practice. There are two disadvantages of spraying alcohol as follows:

1. Whether the concentration of spraying can reach an effective sterilization concentration, if it cannot be guaranteed, it still does not play an effective role;

2. There are also potential safety hazards in spraying alcohol, which may be ** or even ** after encountering a fire source.

Therefore, it is generally discouraged to spray alcohol for disinfection, mainly by wiping. If there is an object to be disinfected, it is also disinfected directly with an alcohol wipe.

Teach you the correct way to disinfect with alcohol.

Alcohol disinfection should first prepare alcohol with a concentration of 75%, wear protective gloves, pour the alcohol into the basin, and then put the rag into the alcohol to soak, and then take out the rag to wipe the items. If the area to be disinfected is small, you can also use tweezers to pick up a cotton ball and dip it in alcohol to wipe the area that needs to be disinfected.

When using alcohol disinfection, first prepare a 75% concentration of alcohol, tweezers and disinfectant cotton balls, open the cap of the alcohol, directly pour the 75% concentration of alcohol into the plastic box, and then use tweezers to pick up the cotton ball dipped in alcohol to wipe the place that needs to be disinfected, and the disinfection can be completed.

If the area that needs to be disinfected is large, you can also wear protective gloves, pour a large amount of alcohol with a concentration of 75% into the basin, and then soak the rag in the alcohol, soak it for a while, take out the rag and wring it out slightly, and then it can be used to wipe the items that need to be disinfected.

If there is no alcohol with a concentration of 75%, you can also dilute the alcohol with a concentration of 95% of the buried sail, you only need to add an appropriate proportion of water directly to it, and then use a rag dipped in alcohol to wipe the items to disinfect. Care should be taken not to use alcohol that is too strong, and to avoid contact with ignition when using alcohol, otherwise a fire may occur.

The method of alcohol disinfection is to use a cotton swab or cotton swab dipped in 75% concentration of alcohol, wipe back and forth on the affected area of the patient, generally 2 or 3 times can have the effect of eliminating microorganisms and toxins on the surface.

When disinfecting, it is necessary to wipe and disinfect repeatedly from the outside to the inside, if it is determined that there are bacteria that need to be disinfected, you can not use alcohol with too high concentration, because bacteria encounter high concentration of alcohol will form a film on the surface of bacteria, resulting in a state of bacterial suspended animation, and then it will be repeated, the main component of alcohol is ethanol, although the disinfection effect is very good, but it is also easy to volatile, and the ignition point is very low, especially easy to cause fire and **. Therefore, if you want to disinfect the items in the room, you usually choose to wipe them directly. Wipe down the items that need to be disinfected with a clean towel and alcohol, and also make sure that the room is ventilated, if the environment is too confined and it may cause danger, and it is also necessary to keep it away from fire and high temperatures.

If alcohol disinfection is used outdoors, spraying can be done directly, because the outdoor environment is not closed. However, in the process of spraying alcohol, you must stay away from open flames, and do not spray near the fire source, otherwise it will cause a fire or **, and the other is to avoid spraying too high a concentration. 75% medical alcohol can also be used to disinfect hands, usually by spraying a small amount and wiping directly if an alcohol swab is available.

If possible, it's a good idea to wash your hands by following the 7-step handwashing method, and then spray a small amount of alcohol on your hands. If you go to the hospital, you also need to disinfect your hands with alcohol after removing the mask to reduce the chance of virus infection.
