The single most critical part of any chainsaw PPE, modern or vintage, resides between the ears of the operator.
If you are confident, proficient and capable of doing your bit, chainsaws are relatively safe.
If you are out of your league and intimidated by the power of the saw, then you are unsafe.
I have seen a lot of idiots dressed in the best available PPE have some ugly near misses or injuries due to operator error, doing stupid things, not applying a bit of thought to tension and compression, wrong tool for the job- or just sheer gung-ho attitude from lack of experience, but a tonne of enthusiasm.
Just use the least utilised app in the box nowadays - common sense.
