Shower hot water shall not exceed what temperature?

Shower hot water shall not exceed what temperature?

• A. 120 Degrees Fahrenheit
• B. 140 Degrees Fahrenheit
• C. 100 Degrees Fahrenheit
• D. 110 Degrees Fahrenheit

Answer: (A)

Shower safety hinges on preventing scald injuries, so the temperature is limited to a level that feels usable but is not dangerously hot. The maximum allowed is 120°F. This temperature reduces the risk of burns if skin comes into contact with hot water, while still providing a comfortable shower for most people. Higher temperatures, like 140°F, can cause burns in a very short time, whereas cooler temps around 100–110°F may be uncomfortable and don’t address the same burn risk. In facilities such as jails, anti-scald devices or thermostatic controls are often used to keep the water at or below this limit.
