Final answer:
Hand sanitizer is not required at hand washing sinks; the essential items are soap, paper towels, clean running water, and a trash can. Soap and water are more effective than hand sanitizer at preventing the spread of diseases like COVID-19.
Step-by-step explanation:
The item not required at hand washing sinks is hand sanitizer. Required items typically include soap, paper towels, clean running water, and a way to dry hands such as hot air blowers or paper towels that can also be used to turn off the faucet and open doors after washing. Proper disposal of used materials is also important, thus a trash can is necessary. It is important to note that hand washing is the best method to prevent the spread of diseases like COVID-19, and while hand sanitizer can be used when soap and water are not available, it is not a substitute for proper hand washing techniques outlined by the CDC. The benefits of using soap and water include the mechanical action of handwashing, which helps remove soils and microbes from the skin, particularly when done correctly - which includes using clean running water, lathering with soap, scrubbing for at least 20 seconds, rinsing thoroughly, and drying with a clean towel.
