Hand dryers are designed to dry clean hands and optimize the subsequent disinfection effect. However, during the hand drying process, we need to prevent our hands from being contaminated, because the hand dryer itself may also become a source of contamination. Therefore, cleaning and disinfecting the hand dryer is particularly important.
In addition, the 10s timer equipped with the hand dryer is not simply the blowing time, but to ensure that the hands can be fully dried. However, experiments have shown that blowing on the hand dryer for only 10s is not enough to dry the hands. A small operational change - shaking your hands slightly after washing your hands, and then moving your hands up and down and putting them into the hand dryer can effectively improve the efficiency of hand drying. It is recommended to clearly include this operational suggestion in the operating instructions for hand washing and disinfection.
