Trapped-key interlocking
Trapped-key interlocking is like a special kind of lock that keeps people safe around machines that can be dangerous. Imagine you have a toy box that's really heavy and can hurt you if it falls on you. Trapped-key interlocking is like a special lock that makes sure you can't open the toy box until you do something safely first.
To unlock the toy box, you might need to turn a wheel or press a button in a special order that makes sure you're doing it safely. This would release a key that you can use to open the toy box safely. If you forget the safe order or try to cheat and open the toy box without doing it safely, the key will get stuck and you won't be able to unlock the toy box.
Now imagine the toy box is actually a really big machine that can hurt lots of people if it's not used safely. Trapped-key interlocking is like a special kind of lock that makes sure the machine can only be used safely by people who know how to use it. The lock makes sure people are doing things in the right order and taking all the safety steps before they can start using the machine. This helps keep everyone safe and makes sure the machine is used the right way.
