For how long should hands and arms be properly washed?

• A. 10 seconds
• B. 15 seconds
• C. 20 seconds
• D. 30 seconds

Answer: (C)

The recommended duration for properly washing hands and arms is 20 seconds. This time frame is crucial because it allows for a thorough cleansing that helps to remove dirt, germs, and other contaminants from the skin. The 20-second rule is supported by health guidelines that emphasize the importance of effective hand hygiene in preventing the spread of infections and illnesses. During this time, it is essential to wash all surfaces of the hands and arms, including the backs of the hands, between the fingers, and under the nails. Following this duration ensures that soap has enough time to interact with pathogens, lifting them from the skin and rinsing them away. Additionally, consistent adherence to this practice instills good hygiene habits, which are particularly important in environments like the Navy, where personnel are often in close proximity and must maintain health standards for operational readiness.
