What warning sign must be displayed for tap water temperatures exceeding a specific degree?

In situations where tap water temperatures exceed a certain threshold, displaying a prominent warning sign is crucial for safety. This serves as a key alert to all users about the potential risks of using hot water, such as burns or scalding, particularly for vulnerable populations like young children or the elderly. The sign effectively communicates the hazard and helps prevent accidents by making everyone aware of the situation before they come into contact with the water.

Having a visible temperature gauge alone might not ensure that users are consistently aware of the water temperature, as they may not check it each time. A daily inspection notice or a user manual does not serve the immediate purpose of alerting users to a current condition, and hence, may not be effective in preventing incidents related to hot water exposure. Thus, the requirement for a clear and accessible warning sign stands out as the most effective method for ensuring user safety.
