What is the temperature range that must be maintained for water at point of use?

The correct answer is centered around the guidelines for maintaining water temperature at the point of use, particularly in residential and healthcare settings. The temperature range of 100 to 120 degrees Fahrenheit is often recommended to ensure that water is hot enough to be effective for purposes such as washing hands or bathing while minimizing the risk of scalding injuries.

Water at temperatures below 100 degrees Fahrenheit may not be sufficiently effective in sanitizing and cleaning, particularly in environments where hygiene is critical, such as healthcare facilities. On the other hand, exceeding 120 degrees Fahrenheit increases the risk of burns and injuries, especially for vulnerable populations such as children and the elderly.

The chosen range effectively balances these needs, providing a safer environment while ensuring that the water is warm enough to encourage proper use and hygiene practices. Therefore, maintaining water temperature within this specific range is key for a variety of health and safety considerations.
