What is the standard duration to wash hands before a service?

• A. 15 seconds
• B. At least 20 seconds
• C. 60 seconds
• D. 30 seconds

Answer: (B)

Long enough handwashing time is essential to remove microbes from hands before service. Washing for at least 20 seconds gives enough mechanical action from the soap to lift oils and microbes from all hand surfaces, including between the fingers and under the nails. Shorter durations, like 15 seconds, may leave germs behind, while longer times such as 30 or 60 seconds aren’t required by standard guidelines and can slow the workflow without adding meaningful benefit. Following the at-least-20-seconds guideline balances effectiveness with efficiency, which is why it’s the recommended duration. Remember to wet hands, lather with soap, scrub all surfaces for the full time, rinse, and dry with a disposable towel, using the towel to turn off the faucet.
