Final answer:
The hand rub can be completed in under 2 minutes by following the CDC's five-step handwashing recommendations: wet hands, apply soap, lather, scrub for 20 seconds, rinse, and dry thoroughly.
Step-by-step explanation:
Completing a hand rub can be done effectively in less than 2 minutes, adhering to the CDC handwashing recommendations for the general public.
Initially, wet your hands and apply soap, covering all surfaces, which should take about 20 seconds. The scrubbing process involves lathering the backs of the hands, between your fingers, and under your nails for another 20 seconds.
A practical tip is to hum the "Happy Birthday" song twice as a timer. After scrubbing, the rinse should be thorough, with water flowing from the wrist to the fingertips, followed by a complete drying with a towel or air blower.
The surgical scrubbing may require more time and extends up beyond the elbows for health professions, but in standard situations, adhering to a concise and effective handwashing technique is sufficient to remove germs and prevent colds and flu.
It's a simple survival skill with a procedure that takes considerably less than 2 minutes to complete if done efficiently.
