Final answer:
The proper temperature for hot water at a handwashing station should be 100°F (38°C), which is warm enough to assist in the proper lathering of soap and removal of microbes while being safe enough to prevent burns. Option B is correct.
Step-by-step explanation:
The hot water at a handwashing station should ideally be at a comfortable temperature that is not too hot to prevent burns and not too cold as to be uncomfortable or ineffective in removing oils and microbes. The options listed are 80°F (27°C), 100°F (38°C), 120°F (49°C), and 140°F (60°C).
According to the CDC handwashing recommendations, hot water temperature is not specified, but it's important that it be warm enough to aid in lathering soap effectively for proper handwashing without causing scalding or discomfort.
Thus, a temperature of 100°F (38°C) is often considered adequate and comfortable for most people. It is warm enough to help with the cleaning process while being safe to avoid burns, making it the best choice among the given options.
The hot water at a handwashing station should reach a temperature between 100°F (38°C) and 120°F (49°C) for effective hand hygiene. This temperature range helps to kill bacteria and viruses on the hands. Water that is too hot can cause burns, while water that is too cold may not effectively remove germs.
