What is the recommended protocol in the proper hand washing technique?

The recommended protocol in handwashing techniques includes several key components aimed at effectively reducing the presence of bacteria and viruses on the hands. The correct choice emphasizes the importance of using warm water along with liquid antibacterial soap. This combination is effective because warm water helps to dissolve oils and dirt more readily than cold water, enhancing the cleaning process.

Lathering and scrubbing for 15 seconds is crucial because the friction created during this process helps to dislodge germs from the skin. The use of liquid antibacterial soap further ensures that harmful microorganisms are killed, thus providing a higher level of cleanliness than washing with plain soap or only water.

Moreover, employing a paper towel to turn on the water is a smart hygienic practice, as it helps to avoid re-contaminating your hands after washing. This method underscores the importance of thoroughness in handwashing, which is essential in preventing the spread of infections.

This choice demonstrates a comprehensive understanding of the best practices in hand hygiene, which is vital for estheticians and overall public health. Other options may fall short in terms of duration, the effectiveness of water temperature, or the exclusion of necessary washing steps, leading to less optimal hygiene practices.
