Weird news - Woman crushed in escalator in China, manages to save child

This is the like a horror story. And yet, it just underscores how so many modern items we deal with on a regular basis can become so dangerous so quickly. And this is not an isolated accident, there have been problems with escalators over the years (why do you think a red emergency stop button was added to escalators for a quick stop of everything). It becomes even more horrifying when you think of how she died (don't watch the video in the attached article if you want to avoid seeing horrifying images). The miracle in this whole episode is how the woman was with her son, and before she died, she was able to hand over her son to 2 employees of the mall, with the son surviving the accident, but seeing his mother dying horribly in front of him.
And why did this accident happen ? Well, seems criminal. A metal plate at the top of the escalator was loose, and as the woman stepped on it, it opened and she was exposed to the machinery. The machinery did not have automatic cut-off to prevent such accidents, and it ground remorselessly on, killing the woman (link to article):

The scene can only be described as horrific: On an otherwise unremarkable morning, a woman is riding up a shopping center escalator in central China with her son. When she reaches the top and begins to disembark, she steps onto a metal footplate covering the machinery. The plate collapses, dropping the woman into the gears. She shoves her child into the arms of two mall employees, and is crushed to death. According to Xiang’s sister-in-law, Xiang apparently was unaware of any problem with the escalator until she and her son had already stepped onto the moving staircase, which was still in motion and not blocked off in any way. People questioned why the escalator was allowed to keep running or was not cordoned off if it posed a danger. Two employees, seen in the closed-circuit video circulated online, were standing at the top of the escalator, apparently trying to talk with Xiang as she and her son rode up.
