Final answer:
When using soap and water for handwashing between procedures or duties, you should wash your hands for at least 20 seconds. This includes cleaning under the fingernails and ensuring that all parts of the hands are thoroughly washed. The CDC provides specific steps for effective handwashing to prevent the spread of diseases.
Step-by-step explanation:
When washing your hands between procedures or duties, if using soap and water, you should take at least 20 seconds to ensure proper hand hygiene. This time frame allows for the thorough cleaning of various parts of the hand that are commonly missed, such as the thumb, wrist, areas between the fingers, and skin under the fingernails. Ideally, to remove any debris or microorganisms, you should also use a nail brush underneath the fingernails.
According to the CDC handwashing recommendations, the proper procedure involves wetting the hands with clean running water, applying about 5 mL of soap, and lathering all over the hands, including the backs of the hands, between the fingers, and under the nails. Make sure to rinse thoroughly from the wrist to the fingertips and dry hands with a clean towel or air blower. It is recommended to use a towel to turn off the faucet and open the bathroom door to prevent recontamination of hands.
Handwashing is a critical and straightforward practice for maintaining public health and preventing the spread of diseases. For health-care workers, regular and thorough handwashing is even more important, as it helps to prevent the transmission of pathogens between patients.
