How to use hand sanitizer? Precautions for using hand sanitizer

The epidemic has created endless business opportunities. Various hand sanitizers have begun to be promoted under the name of "defeating the epidemic, disinfecting and sterilizing", and sales have naturally increased. So, how to use hand sanitizer?

How to use hand sanitizer

Before using hand sanitizer, make sure that there are not many stains on your hands. It is best to keep them as clean as possible. Then squeeze out a coin-sized amount of hand sanitizer, and then rub your hands together until they are completely dry. It is recommended not to eat with your hands immediately after using hand sanitizer, as it may cause accidental ingestion. If there is clean water, it is recommended to rinse your hands again with clean water.

Precautions for using hand sanitizer

1. Avoid accidental ingestion

For young children, they are very curious babies. Don't underestimate their ability to explore. They may try to take a sip when their parents are not paying attention. Some babies have the habit of sucking their fingers, and if the alcohol has not completely evaporated, sucking their fingers may lead to accidental ingestion. Therefore, if you have alcohol-free hand sanitizer at home or use it on young children, you must be very careful to prevent children from accidentally ingesting it, and you must wait until the alcohol evaporates before letting them eat. In addition, the benzalkonium chloride in non-alcoholic hand sanitizer is not volatile. If a child accidentally ingests a large amount of the benzalkonium chloride remaining on his hands, it may also have adverse effects.

2. Fire prevention

When using any item containing alcohol, be sure to stay away from fire to prevent fire. Someone once conducted a ignition experiment using ordinary hand sanitizer and alcohol-based hand sanitizer. As a result, flames suddenly appeared on the hand sanitizer. Therefore, alcohol-based hand sanitizers must be kept away from fire. It is also best not to leave alcohol-based hand sanitizer in the car, because the hot summer weather will cause the temperature inside the car to rise, which may also cause a fire.

3. People with skin allergies should use with caution

Some people are allergic to benzalkonium chloride, which can cause skin allergies, contact dermatitis and other problems after use; some people are allergic to alcohol, which can cause dry and itchy skin after use, and then cause eczema, allergic dermatitis and other problems. Therefore, children and people who are prone to allergies should use hand sanitizer with caution.

4. The effectiveness of using it is greatly reduced when your hands are dirty or greasy

Hand sanitizer is used when hands are slightly dirty, and it has a good effect on some microorganisms. However, when hands are dirty or greasy, hand sanitizer may not work properly, and washing hands with water is recommended in such cases.

5. Traditional hand washing methods are irreplaceable

Using running water, soap and traditional hand sanitizer is still the most basic and effective way to clean your hands. Wash your hands correctly: Use running water, soap or hand sanitizer. Rub your hands for more than 20 seconds each time, and make sure the palms, fingers, backs of hands, between fingers, between nails, wrists, etc. are all clean. Hand sanitizer should be used when washing with water is not possible and should not be used as a daily method of hand disinfection.

6. Long-term use will irritate the skin

Hand sanitizers generally contain ethanol as an active ingredient. Doctors believe that long-term use will irritate and damage the skin barrier.
