People get used to industrial machinery too. Reminds me of the old saying, that a carpenter loses their finger when they stop respecting the saw.

In a professional setting, you have at least two forces ensuring your safety. Your own survival instinct is one. The other one is your boss being liable for accidents at work. Even if you feel super comfortable with your practice, there are other people who'll try to prevent you from doing something stupid - and they have power over you, because as your bosses, they can deny you the access to the workshop.

With a solo op, that second force is missing.
