Habits die hard.
Not electrical but out of 'pipes'. Sometimes in my youth I trained "Young Officers" from a middle east country. Once part way through their course; we had to instruct in rifle range safety and practice. Issue each trainee with rifle, take to training ground, fire off a few rounds, inspect all rifles unloaded and bring men plus rifles back on truck.
As my normal practice, I physically had trainees in a line at practice end and have every rifle unbolted and open and stuck my little finger in chamber to ensure no rounds loaded before they got on truck (I had learned!). But you do not look behind you!
Guys climb onto truck at back end, part way through them climbing aboard , a Bang! Hole about 1 cm above drivers head [N1] in cab. (or roughly less than a thumb width). Getting into truck a guy hit rifle on truck edge & pulled his trigger.
Found out, in their country, it was a major criminal offence in their army to carry an unloaded weapon. They all had a spare round in their breast pockets they loaded into their rifle chamber after I had inspected rifles were empty and collected all 'issued' rounds.
I changed to having rifles issued at firing range by my native UK troops and returned to to my native UK troops after firing practice.
However I found the [N1] driver would never drive me thereafter. Strange.
Habits and culture can ruin any written procedure for safety.
As I worked internationally thereafter, it was a good lesson for my surviving, but with an awful reputation as "he lets the trainees kill one another". "He likes putting his fingers in holes" (without an explanation).
