Tree removal invoice example for Operations

this video series comes with a fully Illustrated workbook and is a certification CEU tests additional workbooks may be purchased from the ISA or naa [Music] now we're gonna look at the actual operation in working safely and efficiently we're gonna talk an awful lot about communication and we're gonna go through something we call the command and response system which is a way for the ground person and the arborist aloft to communicate we're gonna take a look at some rope handling techniques and a few knots you need to know we'll also look at chainsaw use and think a little bit about logical work sequence boy we have a lot to do we better get going sure [Music] one of the first things a ground person might do when arriving at the job site is assist the climber in getting into the tree there are a number of ways we could do this might use a ladder propped against the tree to get the climber into the tree or the climber may actually climb from the ground if the climber is going to climb from the ground he's going to be secured from the moment he leaves the ground assisting us with the climbing today is Ken Palmer a barber master training Ken glad to have you here glad to be here Peter nice nice to have you what we're going to demonstrate first is a means for Ken to body thrust into the tree using me to take slack and to give him a little bit of muscle assistance Ken if you would explain that okay I've got my Blake's hitch tied here on the climbing line and I've got a micro pulley on the climbing line itself just below the climbing hitch I've got a tethered in this case with a dog leash now so as you keep tension and actually even what you're gonna be doing is tending the slack as I climb okay down here in the lower part of the tree it's really not ideal for body thrusting in the sense that my feet won't be tightly against the tree because of the rope angle so I'm gonna be tend to swing a little bit but you can help me by the way you position yourself okay once I get into the limbs of the tree I'll start to climb the tree itself and you can continue to help me by tending the slack by keeping pressure on the climbing line okay you're the boss all right Peter let's do it climbing okay I'm going to spin around here and I've got some Deadwood here Peter stand clear while I check it to see how secure it is all clear okay I think it'll be all right you can continue to tend my slack and I'll climb okay okay very good thank you Peter the climber can sometimes use a ladder to access the tree and of course it's the ground person's responsibility to assist him with that ladder here's a good rule of thumb for setting a ladder if you place your feet at the ladders base and reach with outstretched arms your fingers should just touch the rails and the climber is ascending we want to make sure we foot that ladder and support it until he's off the ladder and then of course once the climber is in the tree we want to get the ladder out of the work area and properly stowed back on the truck another technique that the climber might use to get into a tree is called secured foot lock you can see in this case that Ken is using a prusik loop secured with a prusik hitch to his climbing line and basically with this technique the climber is going to be under his own power to get into the tree and there's very little that the ground person can do to assist with the actual climb that's right Peter I'm going to be sliding the press ik up both parts of my climbing line as I foot lock into the tree so that's gonna be securing me as I climb but in this case I want to start a little doing a little work on this lowest limb and what you can do to help me is swing me over to that limb because it's a little far for me to reach it looks like from here okay you got it okay stand clear all clear climbing okay Peter you want to swing me over there thank you excellent now that we have Ken in the tree we've gone ahead and installed a second climbing line which we call the access line the access line can be very helpful to us particularly in a huge tree like this one to get access to that tree if we have an aerial emergency when ken gets ready to start lowering some limbs we're going to pull this access line out of the work area while the climbers are getting set up in the trees there's a lot of things that we can be doing on the ground to get ready we want to get the tools off the truck and start setting up our worksite we've also taken our rescue bag off the truck the rescue bag has some climbing gear and a first-aid kit and we're going to need this to be ready in case there's any emergency we've also set up a refueling area here you can see we have a tarp and we've set it up in a mulch area we want to make sure we avoid getting any kind of fuel or oil mix on the pavement or on the lawn now with us today we have Tim art of forest applications training incorporated and he's going to tell us a little bit about refueling and maintenance before operation how you doing Tim great yeah thanks well since we have our work area all set here we also want to think a couple things as far as you never want to be smoking or have any type of a flammable item around you're fueling area and always move a fuelling area about ten feet away from your worksite if possible there as we start to look over our saws here it's a good time to make a quick check of any items that may be missing or cracked or loose screws this type of thing also we can do a quick check of our chain tension here to make sure that it's snug and ready to go for our operators and here we want it just to be snug back into the bar and move freely around with a gloved hand and here as we start to inspect we want to make sure too that our fuels and oils are in good shape and the reservoir here on the front is where your bar lubricant is applied and here on the rear is the fuel cap and opening here we can apply the foil as well as the fuel mix and then making sure there's no spills here in this area just take a quick wipe with a rag as you put the caps back in you want to make sure that they seat tightly and no chance of leak therefore the the fuel or oil once all of that is prepared we can quickly get our saws ready and this climbing saw is ready to go up the tree to the workers we can start it up and shut it back off making sure it's going to start up easily for them in the process [Music] Shirin would you send me up a pole saw please sure thing kid this is one of the other duties of a ground worker from time to time climber's going to need various tools or equipment up in the tree and the ground worker needs to be able to tie them on in this case I'm going to attach the pole saw to Ken's line using a midline clove hitch I start by making a loop and I want the standing part of the line on the inside of the loop I twist a second loop up into it such that the running part of the line is also on the inside of the loop then what I do is attach the clove hitch to the pole saw making sure to keep the line away from the blade all set Ken okay we're hauling away then I help guide the tool up into the tree now after climber detaches a tool a lot of times they'll be a bite of rope hanging down and it helps if the ground worker pulls the slack out of the line [Music] make sure your saw is firmly supported with the chain brake on before you start it when you operate a chainsaw on the ground you must wear chainsaw leg protection in addition to your normal kinky heat make sure of your footing before you start cutting avoid cutting with a bar tip especially the upper quadrant of the bar tip operate the saw away from your legs and feet use natural barriers such as limbs between you and your saw running a chainsaw in a tangle of brush introduces kickback hazards trip hazards and struck by hazards from limbs under tension trees segments of trees limbs or saplings bent under tension have to be cut with caution try to find the direction of force acting upon the piece and cut in a way that won't bind or pinch the saw bar or change or create kickback dear Tim uses a notch and undercut to lower the trunk to the ground plastic or soft metal wedges can be used to prevent binding when cutting large pieces block logs with pieces of wood or other suitable material to keep them from rolling when more than one worker is living or bucking a tree each needs to be aware of the others location and activity out here on a tree crew takes a lot of coordination and communication between the people aloft and the people on the ground as a ground person you need to know when it's safe to enter the drop zone under a tree and when it might not be and the climber obviously needs to know where we are on the ground at all times so we use a verbal command and response system to communicate we use commands such as stand clear from the climber all clear from the ground person to indicate when it's safe to get in under the tree and when it's not there are some instances where we can't use a verbal command and we have to use hand signals but the principle is the same all right stand clear all clear a good tree crew plans its work so that it can be carried out efficiently the work you do on the ground must be coordinated with what's happening in the air depending on the site it may be safe and efficient for you to prune what you can on nearby trees while the climber is still getting into position so long as you can make proper pruning cuts this increases the overall efficiency of the job once the work is underway your goal on the ground is to try to keep pace with the work in the tree for pruning this means keeping the area under the tree relatively clear of debris but staying out of the landing zone when limbs are being cut for a rigging operation this means trying to keep the landing zone clear of large entanglements keeping the climbers line clear of brush and sending up and handling lines the climber or bucket operator typically prefers to remove large pieces to speed the job along that means that on the ground you will have to clear brush cut up wood and reduce large pieces for the chipper think about a logical work sequence when you are inspecting the site and developing a work plan [Music] ready for the block and rigging line all right in order to send the block up to Ken I'm first going to thread the rigging line through the block so that I can send them up together after I thread it through I'm going to put a slipknot in the end so that line can't pull back through I make a loop pull a bite through the loop tighten it down that stops the line from going through now to attach the block to Ken's climbing line I'm going to use a sheet Bend that's probably the most common knot used for sending a line up to a climber once again I make a loop thread the other line up through the loop around the standing part back down through the loop dress and set the nut blocks on Ken okay hauling away stand clear all clear Sharon has already sent the ring up to Ken that he's going to need in the top of the tree in order to lower out these big dead limbs while he's busy doing that we're gonna set rigging at the base of this tree so that we can handle the lines properly we're going to be fixing a friction device on the base of the tree this device here now there are a number of different ways we could do that the way we're going to choose on this tree because of the size of the tree the girth of the tree combined with the length of our dead eye or fixed eye sling is what's called a timber hitch fashion a timber hitch we're basically going to create a bite in the rope and a minimum of five tucks to hold that bite which Bob is doing now there are alternatives for fixing something on the base of the tree another good alternative is something called a cow hitch a cow hitch requires that you double over the sling and therefore would require either a much larger sling or a much smaller tree we also want to make sure that we have these tucks going in the right direction we're going to be pulling on this line off to your right therefore we want the tucks going to the left that way we can pull against the bite in the rope pulling in to the bite of the rope would have a tendency to loosen this attachment another useful knot for creating an anchor point on a tree is called a cow hitch a cow hitch might be used with a block by the climber up in the top of the tree or by us ground people down at the base of the tree with a friction device to tie a cow hitch you start out with a bite in the rope long enough to reach around the trunk you want to tie it on the bike goes around the block in the tail go through that bite and then you want to cinch the block up tight to the tree now if this were a larger diameter trunk I would have to walk my rope around the tree in this fashion create the bike come around feed the tail again through that bite now regardless of how I tied it at the end of this I have to secure this hitch with a half hitch around the splice in the rope and then I'd want to neaten it up by taking my tail and making a couple tucks on the back side of the tree on the ground we lower limbs using friction and it's nice to be able to manage that friction in this instance we're using a friction device at the base of the tree there are several advantages of using a friction device over taking wraps around the tree sometimes called spiral wraps those advantages include less wear and tear on the rope easier setup and dismantle you can get from one set to the next set much more quickly and the ability to add and subtract friction to suit our needs line handlers have to communicate well and coordinate their actions to protect people and property as well as to put the limbs where they want them it is a very good idea to wear gloves for this operation Ken's getting set up for his next cut and I want to get the lowering line back up to him he's about 20 feet below the block so I want to tie a slipknot in his lowering line so that won't run through the block I'm going to measure out about 20 feet tie a slipknot that should give him enough rope to work with now when Ken's ready he just gives a little tug on that line and that Slipknot comes right out as you gain a little bit more experience you'll become a valuable second pair of eyes for the climber sometimes the ground man can see things up in the tree that the climber can't spot so it helps out to point out certain branches that need to be trimmed or to make sure tools aren't left in the tree all right sure do you see anything else in this area before I move on this section looks pretty good you got one more out that way and two on the backside stand clear oh Clark by reviewing this video and workbook chapter 4 you should know the proper way to raise and lower set and stow a ladder be able to demonstrate proper chainsaw fuelling and field maintenance understand the proper techniques for lemming and cutting limbs under tension be able to use the command and response system to communicate with workers aloft understand how to handle lines in simple routing situations and be able to assist the climber or aerial lift operator as you can see there's a lot to learn about tree care operations and coordinating work with the arborist a lot on behalf of the NAA and the ISA please work safely [Music] you
