What I was looking for here was, how can we make Industrial Machine's safer and more "user friendly"....

EDUCATE the worker that the guards are there for his/her safety and that the output of the machine is NOT the most important thing about operating that machine. Rather, they being there runing the machine day-in-and-day-out in safe and productive manner.

Until we speak this and walk this line, employees will ALWAYS attempt to defeat the very features we have spent $$$ to protect them!
