During hand hygiene, what is the recommended duration for friction?

• A. 5 seconds
• B. 10 seconds
• C. 20 seconds
• D. 60 seconds

Answer: (C)

The main idea being tested is how long you should rub your hands to remove germs effectively. About 20 seconds of friction is recommended because it gives enough time to cover all surfaces of the hands—palms, backs, between the fingers, under the nails, fingertips, and wrists—and to physically loosen and rinse away dirt and microbes. Shorter durations, like 5 or 10 seconds, often miss areas and don’t remove as many microorganisms. A full 60 seconds isn’t necessary and isn’t practical in routine care. If you’re using an alcohol-based sanitizer, rub until the product is fully absorbed and the hands are dry, which is typically about 20 seconds as well.
