When using an alcohol-based hand gel to disinfect your hands, what is one important step?
Answer:
Using alcohol-based hand gel (hand sanitizer) effectively is crucial for ensuring proper disinfection and preventing the spread of germs. One important step, among several, stands out to maximize effectiveness:
Rub Your Hands Together Until Dry
1. Apply Enough Hand Gel:
- Squeeze a sufficient amount of hand sanitizer into the palm of one hand, typically about the size of a quarter (3 to 5 milliliters).
2. Cover All Surfaces of Your Hands and Fingers:
- Rub your hands together, ensuring that the gel covers all surfaces of your hands, including between your fingers, under your nails, and the back of your hands.
3. Rub Until Hands Are Completely Dry:
-
Continue to rub your hands together until they feel completely dry. This step is crucial as it typically takes around 20 to 30 seconds. Not drying your hands thoroughly can reduce the effectiveness of the sanitizer.
-
During this process, alcohol in the gel acts to kill microorganisms on the skin. If you stop rubbing before the gel has dried, you may not get the full disinfecting benefits.
Reason for Rubbing Until Dry:
Rubbing your hands together until they are dry ensures that the sanitizer has enough contact time to kill germs effectively. If your hands are still wet with sanitizer, it means the alcohol hasn’t fully evaporated and, therefore, hasn’t had ample time to disinfect your skin completely.
Final Answer:
The most crucial step when using an alcohol-based hand gel is to rub your hands together until they are completely dry. This ensures that the sanitizer has fully disinfected your hands, providing the maximum protection against germs and viruses.
