The TreeWorker A monthly resource for the professional arborist PUBLISHED BY THE TREE CARE INDUSTRY ASSOCIATION January 2008 Number 305 How to Use Spurs to Climb Removal Trees What’s this tree? Hint: little fruits are acorns See page 6. Use spurs/spikes/irons only to climb removal trees. Aerial rescue is another possible time, but we’re talking about newbies on spurs, and newbies on spurs shouldn’t be doing an aerial rescue. Before climbing the tree, make a pre-climb inspection of the work site. Look for any potential hazards to yourself or your crew. Since you’re new at this, have a supervisor show you what to look for. Things like rot, structural defects in the tree, mushrooms or other fruiting bodies on the trunk, cracks or cavities in the tree, etc. Be on the lookout for hangers, dead branches, stinging insects, and critters. Make sure you put them on right. There is a right shoe and a left shoe, and the first time (yes you’ll get them mixed up at least once before you figure them out) you get them on backwards will be the time the entire crew will see you and never let you live it down. How to Use Spurs to Climb Removal Trees Get some decent high-top leather boots with a solid heel. Spend a little money because there’s nothing worse while you’re in irons than the heel of your cheapie boots coming off the sole and falling on your groundie. Don’t wear athletic shoes or flip-flops. Actually, go ahead and try them. You’ll find out in a hurry why you need solid-soled boots. Tips for a New Crew Leader CTSP Strategies Install your climbing rope and attach yourself to it. Check the spurs for wear and tear. Make sure none of the straps have cuts or worn spots. We’ll talk about how the straps can get cut later. Check the gaffs to make sure they are secure on the irons. In This Issue... 1 3 4 5 6 7 Some pointers (ha!) on climbing with spurs/spikes/irons for the first few times. Make sure your supervisor sets you up with an escape plan in the unlikely event of a close encounter with the fauna (critters, bees, etc.) on the flora. Have a plan for the entire job from start to finish. Put the spurs on while standing at the base of the tree. The minute you try walking any distance, no matter how short, in sharp irons, you will stab yourself in the calf enough times to realize that you made an error in judgment about where to put them on. This is also a good way to cut or pierce the straps, which could be a very bad thing at 50 feet off the ground. When you walk across that parking ...continued on page 2 ® Hung-up Tree Removal OSHA Files Arborist Quiz Mr. Safety This technique works for certain situations and poses risk, which can be managed. I use this technique most often when I have to remove a tree that has broken off the stump and is hung up. It is used in situations where you can’t just fell the tree away from the trees it is hung up in. The specific case was a dead spruce tree that leaned over an expensive fence toward a house. There were adjacent trees that could be worked from, but we A notch was set up facing the felt it was less risky to pull the direction of the lean, just below tree away from the lean. In this the pull line. by Tim Walsh, CTSP case we set a rigging line (red and white) through the trees behind the dead one, using a 5to-1 mechanical advantage to lift it. The system was anchored to a Port-A-Wrap. The working end of the line ran through the top of the dead tree down the back side and was tied off with a running bowline a few feet off of the ground. I like to pull this way when there is a risk of the tree failing so we would be pulling with the entire length of the tree. (see photo on page 5) ...continued on page 5 Page 2 Spurs The TreeWorker January 2008 ...Continued from page 1 lot, it dulls the gaffs, too. You simply shouldn’t walk in them, except maybe short distances on turf. Attach your flipline/lanyard/safety line around the tree and clip in. Stick the spurs in the trunk (one at a time…no bunny hopping onto the tree), but not directly on the sides. Think about 8 and 4 on a clock face (more or less), especially on larger diameter tree. Try not to “cling” with your toes. Get the feel for standing on the spikes without your toes or ankles touching the tree so you have the correct entry angle. If the entry angle of the gaffs are off as you climb, they will likely kick out, and you get to slide down the tree until your climbing rope stops you. This is always felt most by elbows and knees. Lean your weight into the lanyard when you want to stand on the spikes. As an iron newbie, take a few moments while you’re less than 10 feet off the ground to feel what it’s like to stand on spurs on the tree. It’s wobbly and kind of painful in your feet until they get used to it. The smaller the tree diameter (the farther up you go) the more you have to pay attention to each “grab” you make. Standing on a 4-inch stem at height can be very disconcerting. Practice a little at lower altitudes before you try to take the tall skinny upright branches off. Step up on the spur, keep your upper body a little away from the trunk (don’t hug the tree), and keep your butt in line with your upper body. If the gaff kicks out, your sticking angle is off. Ask your supervisor to watch you and to tell you how to correct this. Make sure you do this under supervision the first few times. Someone has to report to the crew how clumsy you look so you all have something to laugh about when you get really good at it. Don’t stab each gaff into the tree multiple times like you’re trying to kill cockroaches. With the right gaffs, a firm step is all that is needed. Take a couple of steps, move your flipline up, then lean into the lanyard. Take your time. If your boss is yelling at you to hurry up, glare down at him and think of a few tasteless names to call him at a later date. As you ascend, and the trunk becomes teenier in diameter, shorten the flipline to keep your torso the right distance from the trunk. Too close is bad as you will likely kick out. Your natural inclination as a climber is to try to place your feet in branch forks. Avoid this when wearing spikes because you can get stuck or slip. This is a good way to pierce your climbing rope, your lanyard, your foot – all these things are best left un-pierced. Trust standing in the gaffs instead. Get to where you need to be, tie into your climbing line, then relax into your lanyard as you notice “sewing machine leg” take over your lower appendages. Practice, practice, practice, and soon you’ll be shimmying up trees like the monkey’s uncle you are. January 2008 The TreeWorker Excerpted from the TCIA Home Study Crew Leader Manual 3 Characteristics of Great Crew Leaders It’s important to lead by example. Since you work as part of a crew and have responsibilities, what you do often has more effect than what you say. It’s very important to set a positive example. If you say that everyone is to be punctual and ready to work at the appointed time, they will look at you to see if you are on time. If you don’t support management when they ask for things to be done, you can’t expect the crew to support you when you want things to be done. Your actions speak louder than words. What do your actions communicate to the crew? Do they communicate commitment to the job, a high level of quality, concern for customers and concern for employees? No amount of communication will make up for setting a bad example. You are setting an example at all times and in all ways. Great Crew Leaders, as with managers in all businesses, come from different backgrounds and have different levels of expertise. However, they have some common characteristics. While a top-performer may not have every one of these characteristics, the better performers have most of them. A great Crew Leader: Develops each crew member’s capabilities – Great Crew Leaders realize that the crew Page 3 is only as strong as its weakest link. While they may have a new crew member or ground worker, they work to develop them. Training doesn’t stop at just how to be a ground worker. Crew leaders don’t just develop new people, they continuously develop everyone. Delegates or assigns additional duties – We discussed this one in the December TreeWorker. The great Crew Leaders assign duties to allow each crew member to improve their competence in additional areas. Once a person gets good at one task, a Crew Leader can move them to another task, allowing them to learn more about the business and increase their capabilities. Rewards positive behavior – What gets rewarded gets repeated. A crew leader who gets the best out of his/her people is one who takes the time to notice the crew members doing something right and to compliment them. Even if they’re not doing the entire job right, the Crew Leader combines praise for the part they’re doing right with assistance and correction for the part that needs improvement. Sets high expectations – The expectations of the Crew Leader ...Continued on page 6 Page 4 The TreeWorker January 2008 ///////////////// Safety Strategies Success Story! Guidelines for the Safety Professional ///////////////// ® We would like to congratulate Crystal Kappen, CTSP and Jason Kappen, CTSP for a milestone achieved at their company: 16 years without a lost time accident in a company that presently employs 110! As a matter of fact, Kappen Tree Service of Cass City, Michigan, recently received the Michigan OSHA Consultation, Education and Training Division (MIOSHACET) Gold Award for its outstanding safety and health record. The MIOSHA program is part of the Michigan Department of Labor & Economic Growth (DLEG). MIOSHA recognizes the safety and health achievements of Michigan employers and employees through CET Awards, which are based on excellent safety and health performance. The CET Gold Award recognizes an outstanding safety record of one hundred thousand to two million continuous hours worked without days away from work, based on the employer’s size and type of business. According to Jason, the criterion applied to Kappen Tree Service was two hundred fifty thousand hours without a lost-time accident. The Kappens credit their outstanding safety record which was attributed to several areas, including significant employer commitment, an active safety and health committee, job safety analysis (JSA) to identify hazards, regular safety and health training, and a dedication to changing their safety culture. Jason related that TCIA Accreditation together with their CTSP experience helped them organize and prioritize their overall safety effort. Shortly after becoming accredited, Kappen invited a CET Safety Consultant to perform a hazard survey at the company, which is a part of the award process. They passed this audit with flying colors.

The operator had been moving carts containing seedling trees from an outside location to inside a greenhouse. He was using the skid-steer loader for several hours before he was noticed missing. The operator was discovered in a seated position in the operator’s cage of the skid steer with a severe head injury. His left arm was behind him as if to support himself while leaning forward. It was raining on the day of the fatality, and despite the availability of rain gear, the operator had placed his coat tightly across his lap to prevent his pants from getting wet. A pocket of the coat had caught on the skid-steer’s operational hand controls. The controls were probably activated as the victim leaned forward, causing the skid steer to move suddenly. The jolt apparently caused his head to forcefully strike the left-front roll bar. The operator may have been in an awkward position for the sudden jolt, because he was either leaning forward out of his seat to secure the load from inside the cab, or was preparing to exit the skid-steer without shutting off the power. A few additional details from the OR-OSHA investigation point to the second explanation. The operator had just returned from a break, and the greenhouse door was shut when he approached with a new load. The weather was very rainy and windy. He may have decided to jump out quickly to open the door without shutting off the power. The operator may have started to exit the loader, without turning off the power, but when he moved, the coat caught the still-active controls and the machine jolted forward as he exited his seat. No one witnessed the actual events. The victim was pronounced dead at the scene from traumatic injury to the brain. The nursery foreman reportedly had experienced this same sudden movement himself while operating the skid steer in the past, and had also struck his head against the frame but without injury. Recommendations/Discussion Do not operate equipment with loose clothing, a tool belt, or other items that could interfere with or entangle the operator controls. Never exit or lean out of the protective operator’s cage of mobile machinery without first shutting down and turning off the power completely. Maintain the machine in safe operating condition. Employers should consider a formal training process for operators of mobile machinery, including written documentation, and regular evaluation and feedback Hung Up Tree Removal After pulling the tree back to near vertical, a hinge was set up that would direct the tree back into the trees behind it. The dead tree could not be pulled through the trees, so the plan was modified. The mechanical advantage system was taken off, the tree was still anchored so it couldn’t fall back toward the fence, so the tree could be lowered using the Port-A-Wrap. The butt of the tree was pulled off of the stump, parallel with the fence causing the tree to lean to the right (if you were looking at it with you back to the fence. A pull line (blue) was attached to the stem, a few feet from the base. A notch was set up facing the direction of the lean, just below the pull line. (see diagram) The tree was pulled backward using the blue line causing both the top and butt pieces to ...Continued from page 1 come together allowing the top to be lowered to the ground parallel to the fence. The lowering line was still attached to insure that the tree could not fall in the wrong direction. This system is safe as the tree is secured from falling the wrong direction and minimizes the amount of time the workers have to spend underneath the tree. Editor’s note: the basics of this advanced tree removal scenario can be found in the Ground Operations Specialist Manual of the Tree Care Academy and in the Safe Tree Felling Pocket Guide, both from TCIA. I like to pull this way when there is a risk of the tree falling so we would be pulling with the entire length of the tree. Do not operate equipment with loose clothing, a tool belt, or other items that could interfere with or entangle the operator controls. Page 6 January 2008 The TreeWorker What Tree Is This?...continued from page 1 Quercus virginiana - live oak Weight in lbs per ft3 = 76 Common names of Quercus virginiana in different parts of the country are: live oak, Virginia oak, southern live oak, sand live oak, scrub live oak, or Texas live oak. 1400 year-old Angel Oak, located in Johns Island, South Carolina. Photo taken by J. Allen Brack. Depending on the growing conditions, live oaks vary from shrubby to large and spreading: typical open-grown trees reach 50 feet (15 meters) in height, but may span nearly 160 feet (50 meters). Their lower limbs often sweep down toward the ground before curving up again. They can grow at severe angles, and Native Americans used to bend saplings over so that they would grow at extreme angles, to serve as trail markers. They drop their leaves, and grow new ones, within a few weeks in spring. The bark is fur- rowed longitudinally, and the acorns are small, but long and tapered. Live oaks frequently have rounded clumps of ball moss or thick drapings of Spanish moss, and mistletoe is often found on them. Live oak wood is hard, heavy and difficult to work, but very strong. In the days of wooden ships, live oaks were the preferred source of the framework timbers of the ship, using the natural trunk and branch angles for their strength. Southern live oak is long-lived. Trees in excess of 500 years were once common, and one, the Angel Oak on Johns Island, South Carolina, is estimated at 1400 years of age; it is 20 m tall, 2.47 m diameter, and with a maximum spread (longest branch) of 27 m; the crown covers an area of 1,580 m2. It is threatened by nearby development. Crew Leader...continued from page 3 affect the expectations of the crew. A Crew Leader who has high expectations tends to pass that trait on to crew members. As a result of the high expectations, the crew members tend to live up to them. Addresses performance problems – Great Crew Leaders and managers are not satisfied with crew members simply not making mistakes. They strive to elevate each person’s level of performance consistently. If a person is not performing up to their potential or to the level expected of a person in that position, they will quickly address the issue. Doesn’t play favorites – While crew members can’t be treated the same, they can be treated fairly and objectively. The minute a leader begins to show favoritism, it becomes difficult to get top performance out of everyone. Great Crew Leaders are not only objective, they make sure there is not even the perception of favoritism. They explain the reasons for decisions so they’re understood. Is friendly but not too familiar – A great Crew Leader is friendly and approachable, but does not let friendship compromise judgment or actions and affect the crew’s productivity or quality of work. The Crew Leader understands there is a line that should not be crossed. This is especially difficult in small crews and when the Crew Leader and crew members may be about the same age and seniority within the company. Demonstrates integrity – Employees need to trust their Crew Leader. Your integrity and honesty will determine their level of trust and confidence. Those who can be counted on to do the right thing will creat loyalty and commitment. Those who make decisions for themselves at the expense of the crew will find trust and confidence disappearing. Follows policy and procedures – The effective Crew Leader sets examples by following policy and procedures, especially those involving the safety and wellbeing of the crew. Nothing erodes respect and trust like having a double standard, expecting more from others than you expect from yourself. Is candid and honest in communication – Especially in regard to performance feedback or personnel decisions, it’s critical to be candid and honest. Top Crew Leaders and managers separate the employee from their actions and performance and give positive, constructive critique to correct performance and problems. As a Crew Leader, you will be guiding and directing the work of crew members each day. The skills and attitudes you use will make or break the crew. As the crew goes, so goes the success and profits of the company. It’s important that you learn the leadership and management skills required for being effective and use them diligently.
