Utah State University's Soaper Hero program has released detailed guidelines for effective handwashing to combat the spread of microorganisms. The protocol emphasizes a specific five-step method designed to ensure hands are thoroughly cleaned and dried without recontaminating them through contact with dirty surfaces.
The Handwashing Process
The proper handwashing process begins with wetting hands under warm, running water. Once wet, individuals should apply soap and rub their hands together to create a soapy lather. To prevent the soap from being immediately washed away by the faucet, the Soaper Hero program recommends performing the lathering process away from the running water.
Scrubbing Techniques and Timing
Effective scrubbing requires attention to detail to ensure all surfaces are cleaned. According to the program, individuals must wash the fronts and backs of their hands, the areas between the fingers, under the fingernails, and the wrists. This scrubbing process should last between 15 and 20 seconds. To keep track of the time, the guidelines suggest singing the ABC song twice or singing the Soaper Hero Song.
Rinsing and Drying Protocols
After the scrubbing phase, hands must be rinsed under warm running water. To maintain hygiene during the drying process, the program advises turning off the faucet using a clean paper towel, noting that the faucet was likely touched with dirty hands during the initial wetting stage. Once rinsed, hands should be dried thoroughly with a clean paper towel.
Preventing Recontamination
The final steps of the protocol focus on preventing recontamination when exiting the washing area. After drying the hands with a paper towel, individuals should use that same paper towel to open the bathroom exit door. Once outside, the paper towel should then be thrown away. The program notes that hand sanitizers can serve as an alternative when soap and water are unavailable, but they are not a substitute for proper handwashing. The Centers for Disease Control states that handwashing is the single most important method for preventing the spread of infection.
Environmental Factors for Germ Growth
Timing and hygiene are critical to preventing the growth of germs, as microorganisms thrive in environments that are both warm and wet. Because freshly washed hands are often warm and wet, the Soaper Hero program stresses the importance of thorough drying to prevent germ growth. The program also notes that while water temperature is important, it should be a temperature that a person can tolerate; if the water is too hot and becomes uncomfortable, the individual may not perform the washing task effectively.
Critical Times for Handwashing
The Soaper Hero program identifies several critical moments when handwashing is necessary to maintain hygiene. Key times for washing include after using the restroom, before preparing food, and after petting an animal, as animals can carry bacteria and dirt. Additionally, individuals should wash their hands after sneezing, coughing, blowing their nose, or touching a sore.
The Soaper Hero Methodologies
The Soaper Hero program uses a team of characters—Soaper Man, Water Woman, and Dry Boy—to illustrate how different elements work together to battle germs. The program emphasizes that warm water, soap, and a clean drying method are all necessary components for successful handwashing.
