What is the upper bound of the hot water temperature range considered acceptable for residents?

• A. 110 F
• B. 115 F
• C. 120 F
• D. 125 F

Answer: (B)

Hot water safety focuses on limiting the maximum tap temperature to reduce the risk of scalding while keeping the water still usable for everyday needs. For residents, the upper bound that balances safety with practicality is 115°F. At this temperature, the risk of burns from brief contact is much lower than at higher temperatures, giving more time to react if the skin is exposed. Temperatures like 120°F or 125°F carry a much faster burn risk and are more likely to cause injury with even a short touch, so they’re not considered acceptable upper limits. A temperature of 110°F is safe and comfortable but does not reach the upper bound of what’s considered acceptable for residents.
