I will not argue that running a chainsaw is not dangerous. It can be. There is a lot of potential for serious injury. However, with proper training, all dangerous activities can be made safer. No amount of safety gear, for any occupation, activity, etc actually makes the activity safer. It can however prevent injury in the event of a mishap. Wearing a motorcycle helmet does not make you a better rider nor does wearing chaps make you a professional sawyer. I personally am uncomfortable working in a lot of PPE. I am however comfortable using a top handle with one hand.
