What is the maximum temperature for hand washing water in California?

The maximum temperature for hand washing water in California is 120 degrees Fahrenheit. This temperature is established to ensure effective cleaning while maximizing comfort and safety for the person washing their hands. Water that is too hot can cause discomfort or burns, making it less likely that individuals will thoroughly wash their hands.

By setting the limit at 120 degrees, health authorities aim to balance effective removal of pathogens through proper handwashing techniques with the need for a safe and comfortable experience. This helps to promote good hygiene practices, which are essential in preventing foodborne illnesses and maintaining public health standards.

Lower temperatures, such as 100 or 110 degrees, may not be warm enough to effectively clean hands, while temperatures above 120 degrees can pose a risk of burns. Therefore, 120 degrees Fahrenheit is a carefully considered maximum that supports both hygiene and safety.
