Safety mechanisms are often inherently unsafe, because they are safer than the alternative, so you don't want people playing with them.
e.g. You cat cut yourself on the glass of a fire alarm, or break an ankle on an emergency exit slide.
Safety mechanisms are not inherently unsafe. A very small minority that leverage fast-deploying mechanics are, however the majority of safety is neutral. Life vests, eye protection, fall harness, emergency brake, electrical gloves, etc don't actively harm the person.
