Ah pole saw might just be the one then….
The dangers are various
1) jamming, which is the one even pros fear, where the weight shifts of the tree onto the blade and stops it, Generally pros wont have this happen as they read the tree but its always possible and when it happens the energy has to go somewhere.
2) not being stable and your weight shifting whist operating the tool, wheres it going to go now?...
3) working at height with all the normal associated difficulties
But mainly the most dangerous tool is the one operating the tool
When you say saw do you mean a bow saw or a normal wood saw. You want a bow saw for that type of work, but points above still apply, they are damn sharp as well to human flesh, but they wont remove a limb/head with misuse

I bought this one. I'm sure at a cheaper price. It's worked fantastically. I have a long 30m external weatherproof extension reel so I don't care that it's wired as I use that for all my powered outdoor things as it is so i prefer to save money and buy corded which tends to be cheaper and significantly more powerful than cordless variants (bar petrol powered).
You do need chain oil. Which is oil that lubricates the chain. So it eats quite a lot of chain oil as it needs constant lubrication. it does this by itself. It has and oil tank you will up and it should last 20-30 mins before a refill but depends on how hard you are running it i suppose.
it's designed for lopping off high branches but like i said i have actually cut down 7 trees with it, it did take a bit of work but much easier than a hand saw and literally went through branches like a hot knife through butter. it's more than powerful enough for minor domestic use. obviously if you are a lumberjack you would get a proper chainsaw but i'll likely keep on using this as i have 4 more trees to cut down and it's still going strong.
slip with it and head towards your leg... yes very!
Kevlar all the way AFAIK with chainsaws
What about a smaller polesaw?
Well, the pole is adjustable. Not everything has to be cut at 2.7mthe aforementioned pole saw is nonetheless 4.7KG ... so, maybe 4KG you are waving around at 2.7M distance,
over the weight would you have precision to cut cleanly without splintering, or catching the blade -
so how useful is the pole component.

To be honest I think a chainsaw is only as dangerous as the person using it.
I personally think that one of the most dangerous tools is a table saw
a spoon is dangerous if your dumb enough to stick it in a toaster.
A bit of a myth that, when I used to test toasters at Russell Hobbs one of our tests was placing a metal rod on the element to both test the heat and earth.
There should be no bare wires in a toaster so you won't have a problem.
The same test was done on electric cookers where again you place the same metal rod onto their elements testing the same thing.
If you were lazy you just put your hand on it until you had to remove it 2 seconds later.
