Lathes are a good example of exactly what I'm talking about! The manual might say "don't start the lathe with the chuck key still in place" but that doesn't stop people from doing it.

A much better solution is to add a physical safety interlock which prevents you from starting the lathe without removing the chuck key, which is exactly what some lathes do!

I agree the safety level of a lot of Chinese machines is very poor.
