Last issue, we discussed whether it was hazards or is it hazardous energy. The conclusion (although fairly straightforward) is that it’s really hazardous or potentially hazardous energy… which can move. People can also move, which means that eyes and mind on task are very important, which means that human error is important – primary in fact – whenever people are moving or things around them are moving.
So, if we acknowledge that human error is important, the next question is “who?” Whose error caused the incident? Is it always the other person or is it mostly us? And what about when there’s no human error, just mechanical or electrical failure?
