Keep water temperature in your day care facility set at 120? Fahrenheit to avoid accidental scalding. Hot water scalds can be prevented by replacing existing taps with "scald resistant" taps that have built in temperature valves. The thermostat for the valve can be adjusted to varying degrees. Install scald resistant taps in those sinks that children use and remember to set the valve at or below 120? F. Tap water burns are a leading cause of nonfatal burns in North America. As a rule of thumb, turn off hot water taps before the cold.
