Don't you think there are enough rules?....
There should be free training programs offered, some rescue outfits may already do just that.. Maybe they could be listed if they exist.
I did do a chainsaw training course in the NZ'd Army Engineers many years ago and still use my knowledge in the correct use and maintenance or saws today,,, Notice I did not mention safety... The safety that was taught on this course wasn't PPE but how to use a saw correctly..... Needless to say I use a Chainsaw without PPE all the time, where people can get awfully unstuck is not knowing HOW to use a saw, in those cases you should use PPE if you want to survive, I choose not to as it is bulky/expensive and often not on hand at the time, also where I often cut PPE can get in the way in scrub and as long as you know how to control saw and you always maintain a safe saw you will be safe.....
If we are careful we will turn into robots not unlike the support staff I have to deal with in the subcontinent where to do anything you need doco rather than common sense....
How about just legislate "Common Bloody Sense"
