Today a climber, who is new to my crew, walked out on a limb to cut the end off of it. He was lanyarded to the (skinny)limb above him. He tried to cut the end off of it with a pole saw, he dropped the scabbard accidentally. I walked up and saw him struggling to make the pole saw cut and suggested he make the cut with a chainsaw, within arms reach, he responded positively and began positioning himself to switch instruments. I walked away around the corner of the house to check in with another coworker. The climber hung his pole saw from the limb his lanyard was on. With the blade facing him. Started the saw and shifted his weight and the pole saw popped off the limb, fell and cut the back of his right hand, it required 5 internal stiches for the muscle and I think 7 for the skin. He became light headed, but before I could get my gear together from the climb I had just finished, he descended the tree himself. we had the first aid kit there and 911 was just waiting for send. The bleeding looked under control, we wrapped it and another employee drove him to the urgent care center.
I tried to write just the facts up there so hopefully I can get some input from the community about the scenario, rather than my viewpoint of it. It was not a terrible accident, but it could have been worse and I believe it was totally avoidable. We lost time and someone got hurt which I don't like happening on my crew. I'm trying to learn as much as I can from the small accidents so I can avoid making one of those curs-ed pyramids I always see in safety seminars.
This post is long, sorry.
