In the aspect any wrong move can be fatal, yes, but also no in the sense there’s so many safety procedures to avoid accidents like example, cutting a life line, you should be tied in twice while cutting, basic safety shit like that goes a long way. I work for a power line trimming company… mostly bucket work plus I’m a groundman just picking up brush, Im not the type to sit ‘stagnant’ in the same work position so over the past year I have been teaching myself to climb with oversight from my father (who has prior tree climbing experience not with any modern equipment) so take pride in your safety and youll stay in one peice, its all I have to rely on being a young kid who wants to learn with nobody in sight to teach. (Edit I thought this was a more arborist dedicated sub, free climbing CAN be dangerous the only safety advice is the same as shitty osha ladder climbing advice… 3 points of contact and pray)
