It looks like a tool that you could use your whole life and not get hurt as long as you stay alert and stick to the rules. There aren't many bits on it that will guard you from occasional lapses in concentration!
I think the H&S culture of today is a bit silly myself. People got my with stuff like this for generations and if they got hurt it was because they were either very unlucky or stupid. These days it has to be someone's fault which bugs me a little. When I cut the end off of my finger with my bosses hedge cutter the blades weren't coming to a complete stop when I released the throttle and I suppose I could have claimed something for that. I didn't because in my opinion it was my fault for putting my finger in the blade!
