rope placement while blocking down a trunk

Re: Dangerous Technique Alert!!!

Good to see you back ContractClimber.

Hope everything is going well for you.

That is the best post in this whole thread by a long way, you have hit the nail right on the head with the duty of care aspect of this technique.

Your absolutely right, try explaining that one to a judge!

"Yeah your honour, I taught the new guy to cut a notch in the stem that he was still tied into!!!

"WHAT!!!"

"No! honestly your honour, its a tried and tested technique!!!"

"We've been doing it for years!!!"

Even with expert witnesses/expert climbers giving evidence this ain't gonna fly in court of law.

Great post contract, don't be stranger now ye'hear!
 
Re: Dangerous Technique Alert!!!

Back to the original question. This is only my opinion:
Tie in ABOVE your rig. Use a steel core flip line with climbing line as a backup/escape

Climbing lines, lanyards, etc. should not contact any lowering line under load. A 1/2" line can be burned through to failure point in an instant.
 
Re: Dangerous Technique Alert!!!

The techinque that is being discussed is to make the face cut...THEN...take your rope down before making the back cut. If a climber makes the mistake and cuts the top while they're still attached it isn't part of the technique. You're not making a logical arguement. Is someone is taught to drive but has an accident does the driving instructor go to jail? Come on...make a point logically.

One of my friends shared a great tip with me about this technique. When he sets his hight TIP and lowers down to make the face cut he has one of his groundies stand below with the tail of his rope in his hand. This makes the groundie part of his climbing system. The groundie is instructed to stay away from the drop zone and to shout, whistle and shake the climber's rope if the back cut is ever started. Very good advice since this technique has lead to injuries and accidents.
 
Re: Dangerous Technique Alert!!!

I don't want to derail the thread but Tom has made an excellent point generally about envolving groundies in the climbers work, and I just want to highlight it. All of us who climb and cut know full well that you can get into the mind set that those guys in the ground are there to do our bidding, move the brush clear the rope etc.. But we also know that the ground crew often have a much better view of the tree as a whole and of our position in the tree re other parts; if I make my cut here what will happen to the limb out there... Envolving groundies in the climbing process as equals (obviously depending on everyones capabilities) is essential to creating an effective team on the job. Each and everyone of us looking out for the other, so when Tim my groundie shouts to stop me descending telling me to bet the hanger and stub I've forgotten we just look at each other and laugh, had I got to the ground and had to climb back up...noone laughing. Toms' point, using the groundie on the line is a good one, helps to keep everyone focus on the task at hand, reduces the chances of mistakes.

Tom

The logic is the sequence of events that I believe would follow should one of your workers get hurt in such an incident.

A driving instructer teaches us to pull out when we think it is safe, if we want to continue in our journey we have to pull out. We do not have to tie into sections that we are cutting off if we wish to continue felling the tree. That is the principle of Risk Assessment, over here you wouldn't have a leg to stand on! groundsmen responsibility wouldn't even come into it. Dont take/promote 'unnecessary' risks!

In my opinion the drawbacks of this technique outweight the benefits. What are the benefits by the way, a little less fatigue? Have a rest and a drink if thats the case, surely thats the safest solution!

For what its worth at this stage I have the climbing line tight under the block with the flipline above the block.

I have tried to make my point logically, and that is you are opening yourself up to a cycle of events which may not exist doing it another way.

My concern is the climber leaving the rope in the section to be felled.

Grover's concern is being tied to a piece you are cutting into and weakening.

Isn't that what this is all about? Doing it a safer way. Taking preference to the safer way and encouraging that as better practice? Sure there may be instances where an overhead tie helps on a leaner for cutting the notch but then consider this....
....

With plant operating near energized lines we are compelled to have a watchman with whistle that in the event of the plant coming within 1m of the energized lines or above them, the watcher blows the whistle to alert the operator. That is rule. And this rule exists all because of POSSIBILITY.

So it could be written into ANSI that where a climber decides to cut into (notch) a piece of timber that he is supported from (high point)that it may only be done so within eye contact of an observer whose sole task is to ensure the climber retrieves his highline and reties below the cutting point prior to making the back cut.

That's an idea. An idea that's looking for safer work practices from the industry that kills and mames itself the most.

Mind as well just use a blanket statement of use common sence. Like CC said it has been young guys he has hurd things go wrong. Most likely they were thinking with their ego and not common sence. Though I haven't use this technique I do see how it can be useful. This just like anything else in tree work. If you do not feel comfortable doing something well then don't do it. I don't even see this as an issue of rish management. Cutting a notch 1/3 through a 2' diameter log leaves a whole lot of holding wood. Seems even less dangerous then guys crawling into a notch or getting their face at notch level, when on the ground, to eye up the drop area. And personally everytime I have done it I never think the tree is gonna fail and fall on me.

Everybody has a differing perception of common sense, there is no standard for it.

I can imagine the electrical workers safety booklet .... use common sense and you wont be electrocuted. Save a lot of paper wouldn't it?

This industry may be already too far trusting on common sense. Also from my personal experience some of the most intellectually challenged work in it.

There has not been a construction or building site fatality in 2 years here in Australia in the middle of a building boom.

Imagine that.

Wow, they must have hired a stack of people with common sense and to think for all those years they didn't do that.

Now there's a lot less tree workers than in the building game and hmmmm, what's that, 6 dead in 6 months in NSW alone. Gee, we should hand them the 3 wise words "use common sense".

Climber020, yes I am being antagonistic, what it's about is better and safer practices, just like the two tie in rule. Be open minded about things. And if it takes a little longer then so be it.

Re: Dangerous Technique Alert!!!

Why watch day time soap operas on T.V. when I can read the TreeBuzz? :)

Several posters have mentioned the legality of promoting what could be seen as dangerous methods or techniques in certain aspects of tree removals.

When referring to the law, it is best to have a clear understanding of what it is you are saying.

Contract Climber said:
<font color="red"> "Lets say you send one of your crews out and the climber fells a section that he’s tied into with the worst outcome. Before we even consider the obvious moral issues/responsibilities, what are you going to say to the judge? We encourage our workers to tie into the same sections that their cutting off! [Judge] – is this necessary considering the potential fatal consequences? [Tree man] - Er-no but its comfortable. [Judge] – Your defense is based on an assumption that everyone has the same foresight and level of awareness, therefore you have been both negligent and to some extent reckless in the message that you are sending out, Go to jail Mr Treeman!"
</font>

While not an expert on the law, or even a layman for that matter, I have heard of what in the legal profession is called a,

'sophisticated user' defense.

For example: A mechanic at a shop sticks his hand into the path of a rotating cooling fan on a car engine. His fingers are cut off. He attempts to sue the shop owner because the owner did not clearly state (or have documentation of) the inherent dangers of sticking your hand into a moving fan.
Also prehaps the manufacturer of the car did not place warning stickers on the fan shroud.
Can the mechanic prevail in an injury lawsuit?

To use the example being presented here on TreeBuzz, can the climber (or heaven forbid, the survivors) prevail in a lawsuit directed at the owner of a tree company where the climber neglected to remove his/her overhead tie in before completing the cut?

Under the 'sophisticated user' defense, the climber in their capacity as a professional, is EXPECTED to understand the inherent dangers of their profession, and have the sophistication skill &amp; training, to be able to navigate through the dangers of the job safely.

So the answer is no. The climber would not have a basis for an injury lawsuit.
In my opinion, if the climber is up in a tree doing that type of removal, they are sophisticated operators.


Some members of TreeBuzz have referred to ways in which to assess tree decay.
Resistograph, hammering on the bark plates, or even using the 'feel' of your spurs or noticing how the wood chips look and feel when you are cutting or even how the wood hinges when you make a cut. How a tree sways or moves provides valuable information. Even pulling off a little epicormic sucker with your hand can give insights on the tree's health.
These are some of the techniques that give essential information to a skilled climber. The information gives readings on the amount of decay in the tree and it's overall health and stability, or even if it tastes good :).
However, as we all know, a tree can (and usually does at some point), fail. Even with the best information and skill brought to the job.

My take on this thread/on-line argument is that their are many ways to accomplish the job of removing a tree. To steadfastly promote one technique, and one technique only, may have disasterous consequences for everyone involved.




On a final note,
To those of you who say they can out climb/ out work other climbers. It is a virtual impossibilty to actually meet each other and determine this outcome personally.
So why not just leave those types of comments to yourselves? It sounds like a couple of dogs on opposite sides of town barking at each other.
Tottally useless and just annoying.

- I can't disagree with you more there Frans . If someone is talking as much crap as Grover , I'd like to see him put up or shut up . How virtually impossible is it to get a plane ticket ? I'm sure there'S a tree job near an airport. I find your final note useless and annoying . Let the dogs go if their barking , ones gonna have the bite , the other is gonna run .

Here is my final note , here is a few words you don't want to hear when a tree is being removed.
" oh no "
"I knew I shouldn't have done that"
" I think "
" is everything ok "
" CALL 911"
" MOMMY"
 
Re: Dangerous Technique Alert!!!

Fair points Frans, although I don’t believe your comparison between the mechanic and tree scenario is fair. The mechanic’s would be sheer negligence, this particular treeworker scenario in is a little greyer. Car ‘models’ are also identical to one another, we have access to manuals/technology that will predict there exact behavior, with trees we do not!

When a student arborist becomes qualified or certified after a year or so’s study, do they then qualify a ‘sophisticated user’? Or do they have to attain x amount of years out in the field to attain this status, then consider different characteristics and learning abilities of individuals. How do you quantify this status? Its not as black and white as the qualified mechanic chopping his fingers off that’s for sure.

I believe, at present, and although I’m no expert either, such a case would have come down to the discretion of a judge taking into account all of the fact’s circumstances and individuals involved.

If that is the predictable likelihood, my advise would be to cover your back from the offset whereby practical, take as many risks out of the equation as possible. I don’t believe that it would be such an impractical/unreasonable sacrifice to ask your workers to refrain from using this particular technique.

That’s all I’m saying, prevention always better than the cure. That’s me out. Thanks. Reg

Riggs,

I don't see much benefit in using the overhead tie in technique to cut a notch.

There is a risk albeit a small one that you could cut through the only good wood at that point in the stem leaving only decay or a cavity leading to stem failure.

There is also an increased risk of cutting through your climbing line using this technique as opposed to the regular two tie ins below the notch.

There is also the possibilty of forgetting to remove your climbing line before you make the back cut.

Any benefits of using this technique are quickly superceded by the disadvantages.

It really shows a lack of ability as a climber to have to resort to using the overhead tie in to improve your work position when making the notch.

When I see someone do this during a takedown I'm thinking, "jeez! whats up with him, can't even make a decent notch without the top tie in"

I'm talking crap am I?

Lets just leave it at that then.

Otherwise I'll be bringing Big Burd, Kermit and Elmo across to PA to kick yo azz.

It's only 'WACK' cause you can't comprehend what we are all talking about,
but at least I know you would never use this technique right?

Cause you don't use SRT off any description.

You just lanyard and spike down the stem as normal, right, nice one MB.
