What strategy helps prevent hot-water scald injuries in preschoolers?

• A. Set water heater to 120°F (49°C) or lower; test bath water; supervise baths; use anti-scald devices.
• B. Set water heater to 140°F (60°C) or higher.
• C. Let child run the bath unsupervised.
• D. Do not use anti-scald devices.

Answer: (A)

Preventing hot-water scald injuries in preschoolers hinges on controlling bathwater temperature and maintaining vigilant supervision, with an added safety net through anti-scald devices. Setting the water heater to 120°F (49°C) or lower reduces the risk of severe burns because young children have thinner skin and can be burned quickly, even with brief exposure. Always test the bath water with your wrist or inner forearm before a child gets in to confirm it isn’t hotter than intended, accounting for any fluctuations in the heater or other taps. Active supervision during baths is essential, since a quick slip or a curious splash can lead to scalding if the water is too hot. Anti-scald devices or thermostatic mixing valves limit the maximum temperature of the water reaching the child, providing an extra layer of protection even if other controls are imperfect. Higher temperatures dramatically raise burn risk, and letting a child bathe without supervision or skipping anti-scald measures leaves avoidable danger. This combined approach offers the best protection against scald injuries in preschoolers.
