First please read this earlier post where I noted how Hydrotherapy equipment for my physical therapy after a foot surgery had “scalding” temperatures set to 120°F (Figure 1).
Figure 1 Hydrotherapy equipment with scalding water temperature is 120oF and beyond.
Then see this more recent post and be prepared for a shock.
The post on Inside Edition describes how a man was killed after being exposed to a water shower where the hot water temperature was 150 degrees Fahrenheit (150°F). This was way, way higher than the scalding threshold of 120°F mentioned in the earlier EDN post.
No mention was made, but I rather suspect, that the man who was killed may have let the hot water run for a while before stepping into the shower to avoid being chilled by cold water and that he did not test the shower water by hand first. Had he checked, he would have avoided the scalding.
