It depends if people pull the key and carry it with them when entering the cage.
I've had coworkers open the gate and not noticed the chain to the gate sensor broke, he was doing a tool change and only saved he's ass by turning off the robot call on the lathe before the door opened.
Older story from before I worked there a different cell had the gate sensor bolted to the door not chained so the key remated when the door swing shut, then someone though the robot just errored out and pressed resume, I think it broke the maintenance guys back. The force settings was low enough it didn't push through him but those robots have the strength to do so.
Overall a robot doing this job will save a lot of backs, shoulders, wrists, and lungs as factories tend to slowly kill the people working in them.
Yeah people should practise LOTOTO with machines, but not everything is up to that standard. Also when a chain on any safety related device breaks the safety circuit should never be able to be completed. Shit happens though, and systems get bridged, leading to accidents like that.
Safety standards are written in blood. And while they may be cumbersome at times and slow down work, it beats not dying or injuring yourself or someone else.
