Hazards of Tree Climbing?

So what happened?
 
Lotsa good stuff here fellas. No lines in the sand though OK? Were all on the same team, if we have different opinions, GREAT!

Mahk, I checked out Tree Worker Safety CD, it's pretty good-I'd recommend it for any tree company safety program. The flowchart you mentioned flows well due to it's interactive format although a little cautious- most of the final answers are "Wait! Do nothing until EMT's arrive". That's sound advice for crewmembers inexperienced with rescue but I'd like to think my groundie could do something in those first few critical moments. I know I know- don't become a second victim-most important. I've been doing alot of research and the picture I'm getting is that aerial incidents come in three sizes-benign(no injury, just stupidly stuck), extreme life threatening injury, and instant death. It's in the middle category where adequate training could help save some lives.
As for the list, I would prefer not to think of it as an entity in itself but a product of it's content. So here goes:
Hurt hands are off- I think no matter how bad froze or burnt or broken my hands are I could still get to the ground.
Beard in hitch can go under Hitch Trouble, so tophopper, how did the guy get down? I caught a glove in my hitch once so bad I had to untie it, could have been bad on a straight down rapel.
How about Chainsaw Cut by itself? I think if I was ever cut bad the first thing I'd do is get to the ground.
Electricity appears to be the worst thing plaguing our industry, even worse than falling or chipper death. Although it's usually an instant killer some people do live after electrocution, but only if they recieve treatment immediately. (got AEDs?)
Okay, I'll get off my soapbox now, over and out.
 
I was helping instruct a girl's survival course (like Outward Bound) and a girl with long hair didn't put it up like we told her...it got sucked into the biner wrap we were using at the time (standard then, pretty much verbotten now).

She was stuck about 30 feet up a rock face, ear near the biner at her waist and not too happy. Two of us rappelled down to free her. She saw me take out my Case knife in preparation to cut her hair (would have been dicey, blunt-tip scissors would have been better...good argument for EMT shears). When she saw the knife she saved me the trouble of cutting her hair. She screamed, "You're not cutting my hair!!" and pulled her head away from the biner so fast that she snatched her hair out...self-correcting.

End of story.
 
I had a trunk split lengthwise a few weeks ago on a Red Oak.
The tree was leaning away from the intended lay.
I cut and turned the tree ok but the force on the stump was great and it split and pulled one side of the stump up out of the ground about an inch above the other side.
The oak was 28"DBH, it really put a huge force on that stump causing it to split up the middle.

What does cut and turned mean?

Was it leaning 180 degrees away from the direction you meant to fell it?

Did you have a rope up high to help encourage it past the zero degree point?

Did you use wedges?

Would side kerf cuts have helped prevent the problem?

I am working through Dent's book and want to understand these things better.

Thanks.
 
For turning a tree you want more wood (holding wood) on the side of the hinge you wish to turn the tree.
Check page 99 in Dents book.
The tree in question was leaning towards the water and the guy I was working for wanted it dropped on the beach which meant I had to get the tree to swing over to the side away from the trees natural lean.
The tree turned ok but the stump really felt the strain of the tree as it was leaning towards the water but being forced in a different direction.

Does anyone else find Dent's book painful to read?

In terms of the oak splitting (I'm not sure if it was the trunk or the stump which split -- the description could have it either (both?) way) it sounds like the pie was sliced a little thick, making it too inflexible.
 
Glen, being the main part of the tree it's a trunk when you start and a stump when you're finished.
What was split with the force was the stump and you are correct in the amount of holding wood in the hinge being substantial due to the size of the tree,natural lean and the distance the tree had to turn.
 
OK Trunk splitting, Well we were clear cutting for a park in a down town area. So I was up about 20 feet in a box elder it was about 24" at that point and went to make my useual face cut and dump the raimaining 30'. Since that little argument about trunk splitting I have always wrapped my lanyard completely around the tree and hook it to my d rings then tie in with my usual rope but backed it up with my figure 8, my supervisor called it stupid because we were in the middle of winter and the tree would more than likely snap in stead of split but I didn't want to take the chance. Well I started the finall cut got about 10" of hing and it started to go surprised I tried to pull the sawout and hook it. But before I could it split A monster split!!!. From It tore about 20 ft above my head sending the butt end flying throught the air and giving a nice lovetap in the face, before sliding down my leg. Below me it split about another 10' down which in turn sucked all the slack from my lanyard sucking me into the trunk(hence the reason for hooking my lanyard to my D's, instead of the usial placemnet so I wouldn't be suffocated). I had to cut the lanyard to get down. First thing I said with a bloody lip was "is the saw Ok"

When all the was said and done just a split lip and a bruised knee. MY supervisor has spent 20 years in the tree bizz and has never seen it happen. But was glad I took the extra steps to ensure safety and I just recently seen him practicing the same on our last job. Thanks TreeBuzz!!!!!!
 
demo, did you say clear cutting, Or selective removals?
Were you in the tree because there wasn't room to fell it and you were protecting other trees? DId you guys have a tag line in the section you were cutting? GLad your OK. Sounds "freaky" Just trying to figure out why it did that.
 
I think it is kind of fun and entertaining to think about awful ways to end. I think about it all the time, its kind of interesting to see what others think about. I think it is a naturally installed defense structure that "the itelligent designer" or the great ID made so that we could steer clear of imaginated disaster scenarios.

Cutting the top out of a tree while tied in to it
brainfarting
clipping biners wrong
tying knots and not setting them or tying them wrong
not double checking
trusting somebody else to not do something stupid
or trusting that they see you.
trusting gear blindly
rushing
not creating disaster scenarios in your head

are some more things that can kill you in this work
 
Hey Demo...could you please explain how you back up your main line with a figure eight? I have some ideas about it but am not too sure as I have never seen it. Thanks
 
The tree did Have a good lean to it, and it was own of those house lot parks in the middle of the city(long and skinny), so the way it was leaning we reall couln't redirect it and the simplest thing would to sit in it and top it at that height.

Phil,

What I do is tie in like I normally would, but I leave enough slack in the line so I can attach my figure eight,with a hard lock, before my friction knot, just in case it takes all my slack from my climbing line the figure eight will take the force, instead of letting the friction not, that way I can still work with the knot Instead of it being "loaded" and unable to work with it. It seems redundant with the lanyard keeping the trunk from splitting that far but, if the lanyard failed or was cut it would come in handy, and if I can't work the figure eight, I could just disconnect it from my saddle, IT does seem very redundant. But Feeling a little more comfy in a tree during removal isn't all that bad is it?
 
This list could go on for ever. we kind of operate with the unspoken knowledge that we can be killed at any time due to some random variable in our work. But most of us accept that there is always a small percentage for death or injury , and do not dwell on it. Dwelling on it only clouds one s mind and impairs their ability. i have personally had two friends killed and two seriously injured to where he can no longer work at all.. the deaths..one electrocution ..one had a full skirt palm collapse and pin/suffocate him...
The injury..climber on a limb walk..no lanyard..branch broke..knot ran.. hard hat fell off.. climber fell head first approx thirty feet into a crotch...suffered traumatic brain injury..lost some teeth...cant balance anymore
Next injury ..climber had a twenty inch saw kick back and hit one hand.. severed a couple tendons and an artery... self rescued lost use of two fingers.. no longer climbs...
Moral of the tale...train, train , train, for everything..always work with two climbers, keep doing cpr and ariel rescue practice.. and accept that you may have a life changing experience at any time... but do not dwell on it and be blessed in your life as a climber
