I am 34 and have been climbing for 7 years and a lic arborist through the state of Rhode Island.I was also a volunteer firefighter/emt for 11 years on a heavy rescue truck.I never thought that someday I would be the victom! I own my own tree company and employ 2 ground men(brush monkeys).All we do is climbing no bucket trucks,which I have grown to like because I have other tree and landscaping companys hire us out when real tough jobs need to be done.It all started on a day were rag weed polline was very high and my allirgies were kicked into high gear.I am reluctant not to take any allirgy meds will I am climbing.As I dawn my climbing gear which consist of hard hat,saftey glasses,leg chaps,kevlar arm gards,rubber palmed gloves and harness I start what should be a three hour job removing about ten limbs from four trees over a house. All was going to well, I just bought a new sthil pole prunner that I let a salesman talk me into.I found alot of use for it while in the tree(not having to limb walk as much).After about two and half hours the chip truck needed to be emptied,I thought that I would have had enough room too finish the job.So I told one guy to go empty the truck but it was close to cofee brake and the other guy needed to go by the bank (he didn't have a lic to drive the truck so I let them both go.I got my climbing ropes up the tree about 20 feet higher than the limb to be cut( tied of to the trunk). I only had one branch left to cut and thought I would be alright alone.Just after the left I relised I didn't have my pole prunner up there with me.So I decided to limb walk to get to the end and cut small pieces.After I was out about 12 to 15 feet I lost my balance. I fell head first and swung into the tree trunk! My hard hat was knocked of my head and I swung back into the trunk from the other direction, this time I hit without the hard hat and was knocked unconcious. The nighbors saw me hanging and called 911. some how they got me down to the ground. when I woke up in the back of the ambulance I could not feel my arms or feet!After a stay in the hospital for 4 days I walked out with nothing more than a real bad head ache and a sore back. Thanks to weiring my proper saftey equiptment I walked away with some spinal swelling and a hurt ego. That day I learned that I made a few real bad mistakes.one, I never should have been alone. and two I should have waited for the guys to come back because the dump was only 1 mile away.
