One goal of the regulatory approach to tap water scald prevention is the installation of hot water heaters at thermostat settings considered safe. In this strategy, it is assumed that consumers will not change preset thermostat settings, an assumption evaluated in a study of 62 families. It was found that 60% of the sample did not change their preset thermostats. Surprisingly, some of those families (27%) who did not increase their settings still had unsafe (> 54 degrees C) water temperatures.
监管方法预防自来水烫伤的一个目标是将热水器安装在被认为安全的恒温器设置上。在这个策略中,假定消费者不会改变预设的恒温器设置,这一假定在一项针对62个家庭的研究中得到了评估。结果发现,60%的样本没有改变他们预设的恒温器设置。令人惊讶的是,一些没有提高设置的家庭(27%)水温仍然不安全(>54摄氏度)。
