What is the recommended temperature limit for hot water to prevent burns?

The recommended temperature limit for hot water to prevent burns is 120°F. This recommendation is based on the fact that water heated to this temperature can cause serious burns within a matter of minutes, especially in vulnerable populations such as children and the elderly. At 120°F, the risk of scalding still exists, but it is significantly lower compared to hotter temperatures.

Water temperatures above this threshold increase the likelihood of burns; for instance, water at 130°F can cause burns within 30 seconds, while water at 140°F can lead to burns in just five seconds. Staying at or below the recommended limit of 120°F helps ensure safety while still providing adequate heat for sanitation purposes.
