What must be displayed for taps delivering water at 125 degrees F or above?

A warning sign must be displayed for taps delivering water at 125 degrees Fahrenheit or above to alert residents and staff to the potential risk of scalding or burns. This requirement is rooted in safety regulations, which aim to protect individuals from dangerous water temperatures that can lead to serious injuries, particularly for vulnerable populations such as the elderly or those with disabilities, who may have impaired sensitivity to heat.

Having a visible warning helps ensure that anyone using the water is aware of the risk before they come into contact with it, allowing them to take necessary precautions. The placement of such signs is a common standard in facilities to promote safety and awareness.

In contrast, the other options do not provide the same direct and clear alert to individuals regarding temperature risks. While protective covers, emergency shut-off switches, and caution notices can enhance safety in various ways, they do not serve the specific purpose of immediately informing about the hazard associated with high-temperature water.
