Information about hot water scald burns
Every year, thousands of people suffer serious thermal shock and/or scalding injuries in their shower or tub/shower fixtures. The tender skin of very young children and the slow reaction time of the elderly and the handicapped make them most vulnerable to serious hot water burns. Scalding injuries are tremendously painful, and the effects can last for years. Scalding occurs for a variety of reasons. In some cases, water heater thermostats are faulty, or set too high. In others, temperature regulating valves at the domestic hot water source are either malfunctioning or missing altogether. Water heaters are normally set to temperatures above 131°F (55°C) to prevent development of harmful bacteria, such as Legionella, in the water supply. However, at a temperature of 131°F (55°C), a child can be scalded in less than 4 seconds.
The goal of this web-site is to teach you, the public, about safe practices for water heaters and temperature regulating valves to best prevent hot water scald burns.
