First rule of fixing things that can kill you: power it off. Before you do anything, power it off. Then, check again to make sure it’s powered off. Maybe check a third time just to be ABSOLUTELY sure. Put a physical blockage on whatever you need to so it can’t be powered on while you’re working on it - zip tie the breaker open, throw the power cord over a pipe or under the machine, hit the knife-switch on the side of the machine in addition to throwing the breaker, whatever you need to.
Hell, if you need to, get your coworker to stand there and yell at anyone trying to turn the thing back on. That’s how we did it when anyone had to fix the cardboard baler at my old grocery store - power off at wall, power off at baler, and at least one, preferably two people watching to make sure nobody did anything stupid.
You’re correct if that’s the case. I re-read the linked article but didn’t see anything about carelessness on the inspector’s part.
Edit: Of course, he could have been wearing one of the company’s free T-shirts showing off their products, but…
The machine ‘thinking he was vegetables’ is stupid as the system just loads things onto another thing, it doesn’t think something is a plant or animal or anything like that. It just thinks an object nearby is a thing it is supposed to move and reads the size and shape of nearby objects to know where the arm goes.
What the person was wearing is irrelevant unless they wear a highly visible symbol or color for it to read as ‘don’t move thing with symbol or color’ and even then you wouldn’t want to have it on when fixing it if it was having sensor problems.
So he didn’t engage the safety lockouts that any heavy machinery that is being inspected should have in place and got in the way of the machinery.
This is the same as a guy being under a crane and testing whether it is holding something securely by standing underneath.
