What temperature must hot water reach in resident areas to ensure safety?

To ensure safety in resident areas, hot water must reach a temperature that effectively prevents both scalding and minimizes the risk of legionella bacteria growth. The temperature range of 95°F to 120°F is considered appropriate because it is warm enough to be comfortable for bathing and personal hygiene without presenting a significant risk of burns.

Hot water at temperatures exceeding 120°F can lead to scalding injuries, particularly in populations such as the elderly or those with sensitive skin. Conversely, temperatures below 95°F may not provide adequate warmth for residents' comfort during activities like bathing.

Therefore, maintaining water within the specified temperature range strikes a balance between safety and comfort, making it the ideal standard for assisted living facilities.
