All applicable requirements in Section 3, General Safety Requirements, shall apply to this section.
A second arborist, an arborist trainee, or other worker trained in emergency procedures shall be within visual or voice communication during arboricultural operations above 12 feet (3.65 m) that are not subject to the requirements of Subsection 4.3.9.
Arborists shall inspect climbing lines, worklines (line, workline), work-positioning lanyards, and other climbing equipment for damage, cuts, abrasion, and/or deterioration before each use and shall remove them from service, per manufacturers’ guidelines if applicable, if signs of excessive wear or damage are found. Climbing lines or worklines that are removed from service may be used for other noncritical purposes if deemed suitable for such use by a qualified person.
While working aloft, the climber shall have available a climbing line and at least one other means of being secured on his/her person at all times (e.g., an arborist climbing line and a workpositioning lanyard). Two means of being secured shall be used when the climber determines that it is advantageous.
The climber shall have a hand saw available while working aloft. Hand saws aloft shall either have a scabbard or be of the folding type that covers the cutting teeth when closed.
The arborist shall be secured at all times while ascending the tree, including when using climbing spurs/gaffs. The arborist shall be tied in once the work begins and shall remain tied in until the work is completed and he/she has returned to the ground. The arborist shall be secured when repositioning the climbing line. When repositioning, the arborist shall preload the new tie-in point with his/her full weight before releasing the current means of being secured.
While ascending a ladder to gain access to a tree, the arborist shall not work from or leave the ladder until he/she is tied in or secured.
Hands and feet should be placed on separate limbs, if possible, and three points of contact should be maintained with the tree while climbing.
A false crotch and/or false-crotch redirect may be used at the discretion of the arborist in lieu of a natural crotch.
The climber shall select a tie-in-point/primary suspension point that prevents lateral movement of the climbing line.
When installing the climbing line or false crotch from the ground, it should be positioned in a suitable location along the main stem/leader/lateral limb. The climber shall visually inspect the anchor point for condition from the ground and, if suitable, shall subject it to a load approximately twice the weight of the climber before climbing commences.
The tie-in point should be positioned so that the arborist will not be subjected to an uncontrolled pendulum swing.
When an arborist is working at heights greater than one-half the length of the arborist climbing line, a stopper knot shall be tied in the end of the arborist climbing line to prevent pulling the line through the climbing hitch.
Arborists working from a stem or spar without a suitable natural crotch shall select tie-in points or a tie-in method that positively prevents the climbing line from sliding down or up or off the stem during climbing operations. Placing a climbing line around a stem in an area without a lateral limb is not acceptable unless the climbing line is cinched or choked around the stem or runs through a double wrapped or adjustable false crotch, which is secured/cinched around the stem. The tie-in point selected shall be able to withstand the forces being applied during the pruning/removal operation.
If a climbing line is damaged in the course of operations, the arborist shall secure himself/herself with a work-positioning lanyard and immediately replace the damaged line.
The ground crew shall keep the climbing line free of debris and obstructions, protect it from damage, and report any damage to the arborist.
The arborist shall check his/her climbing line beneath the climbing hitch for damage while descending.
Climbing lines used in a split-tail system and split-tails shall be terminated with an eye splice or a knot that interfaces appropriately with the connecting link. When using a carabiner without a captive eye, the termination selected shall maintain loading along the major axis. The connection between carabiners and terminated rope ends shall be compatible to limit the possibility of accidental disconnection or minor axis loading of carabiners.
The arborist shall assure that arborist saddles and climbing gaffs/spurs comply with an appropriate governing standard, and shall be marked accordingly on the product, when new (e.g., arborist saddles marked ASTM F887 if manufactured after 1/1/2018).
Arborist saddles and work-positioning lanyards shall not be altered in a manner that would compromise the integrity of the equipment.
Arborist climbing lines used for moving rope systems shall have a minimum diameter of 1/2 inch (12.7 mm) and be constructed from a synthetic fiber, with a minimum breaking strength of 5,400 pounds (24.02 kilonewtons [kN]) without terminations when new. Maximum working elongation shall not exceed 7 percent at a load of 540 pounds (2.402 kN). Arborist climbing lines shall be identified by the manufacturer as suitable for tree climbing.
In arboricultural operations not subject to regulations that supersede Z133, a line of not less than 7/16 inch (11 mm) diameter may be used, provided the employer can demonstrate it does not create a safety hazard for the arborist and the arborist has been instructed in its use. The line selected shall meet or exceed the standards for arborist climbing lines and shall be identified by the manufacturer as suitable for tree climbing.
Arborist climbing lines used for stationary rope systems shall conform to the diameter, construction, strength, and elongation standards of Subsection 8.2.4 and shall be compatible with the components used in the stationary rope system.
Prusik loops, split-tails, doubled-hitch cords, and work-positioning lanyards used in a climbing system shall meet the minimum breaking strength of 5,400 pounds.
Hitch cords, Prusik loops, and split-tails shall be manufactured from material(s) suitably resistant to the abrasion and temperatures experienced during work and rescue scenarios.
Snap hooks (rope snaps) used as part of a climber’s work-positioning (suspension) system shall be self-closing and self-locking, with a minimum tensile strength of 5,000 pounds (22.24 kN).
Carabiners used as part of a climber’s work-positioning (suspension) system shall be self-closing and self-double locking and shall have a gate-locking mechanism that requires at least two consecutive, deliberate actions to unlock. A carabiner shall be capable of withstanding a 5,000 pound (22.24 kN) load along its major axis with the gate closed without breaking or distortion sufficient to release the gate.
Carabiners and snap hooks used as part of a climber’s fall protection (work-positioning/suspension/fall-arrest system) shall not be linked together unless designed to do so and accepted by the manufacturer.
Load-rated screw links used as part of a climber’s work-positioning (suspension) system shall have a tensile strength of 5,000 pounds (22.24 kN) and shall be securely tightened to ensure they will not unintentionally open during use.
Splicing shall be done in accordance with manufacturers’ specifications.
Equipment used to secure an arborist in a tree or to an aerial device shall not be used for anything other than its intended purpose.
An arborist’s climbing line may be used to raise and lower lightweight tools and equipment such as chain saws, hand tools, and additional lines.
Rope ends shall be finished in a manner to prevent raveling.
Ropes and climbing equipment shall be stored and transported in such a manner to prevent damage through contact with sharp tools, cutting edges, gas, oil, or chemicals.
Arborist climbing lines shall never be left in trees unattended.
Climbing spurs shall have gaffs of the type and length suitable for the tree being climbed. Manufacturers’ recommendations for inspection, maintenance, sharpening, and replacing worn gaffs shall be followed.
The non-working end of any work-positioning lanyard shall have a fixed termination such as a fixed stopper knot, eye splice, snap, carabiner, or other hardware that does not permit the non-working end of the lanyard to advance through the friction device, or it shall be securely connected to a rated connection point on the climbing saddle.
Pruning should be conducted in accordance with the ANSI A300 (Part 1) standard.
The arborist in charge shall establish a safe work plan to manage the drop zone. Communications among arborists aloft and other workers on the ground shall be established before cutting and dropping limbs. The command “stand clear” from aloft and the response “all clear” from the ground are terms that may be used for this purpose. Pre-arranged, two-way hand signals may also be used. Arborists and other workers returning to the drop zone shall be acknowledged by arborists aloft.
Pole pruners and pole saws, when hung, shall be securely positioned to prevent dislodgment. Pole pruners or pole saws shall not be hung on electrical conductors or left in a tree unattended. Pole saws and pole pruners shall be hung so that sharp edges are away from the arborist and shall be removed when the arborist leaves the tree.
Scabbards or sheaths shall be used to carry hand saws. Folding hand saws, when not in use, shall be stowed in a manner that protects the worker and others from the cutting edge.
Pole tools used in proximity to energized conductors shall be constructed with fiberglass-reinforced plastic (FRP) or wooden poles meeting the requirements of OSHA 1910.269(r)(1)(iv).
Limbs that cannot be safely controlled by hand or free-dropped shall have a separate rigging line attached to them to help control their fall. Rigging practices shall conform to the requirements in Section 8.5, Rigging, of this standard.
Dry conditions and dead palm fronds present an extreme fire hazard. When dry conditions exist, arborists and other workers shall not smoke while working in or near dead palm fronds. All chain saws used under such conditions shall have mufflers and spark arresters in good working condition.
Palm frond skirts shall be removed from the top down. Arborists performing this work while climbing shall be supported by an arborist climbing system, and when possible, positioned above the skirt. Arborists should not remove palm skirts by positioning themselves below the frond skirt or between the palm skirt and the trunk of the tree.
Cut branches, tools, and equipment shall be removed from trees upon completion of work.
Cabling should be conducted in accordance with the ANSI A300 (Part 3) standard.
Arborists and other workers on the ground shall not stand in the drop zone when a cabling system is being installed.
Tools used for cabling shall be carried in a bag, placed on a belt designed to hold such tools, or securely attached to a lanyard (tool lanyard) to prevent the tools from falling.
When installing or replacing a support system, the load shall be released onto the new support system in a slow and controlled manner to help prevent sudden or dynamic loading.
When a previously installed support system is to be removed or replaced, it shall not be removed until a new support system is installed to take the weight off of the previously installed system, or until a temporary support system has been installed to slacken the previously installed system.
Arborists performing rigging operations shall inspect trees for their integrity to determine whether the trees have any visible defect that could affect the operation. If it is determined that the tree poses a risk of failure due to the forces and strains that will be created by the design of the rigging operation, an alternate plan shall be used.
Rigging points shall be assessed for their structural integrity by a qualified arborist. The work plan and the tree shall be considered relative to the forces being applied to any part of the tree, including branch attachments and anchoring roots, before a rigging point is chosen and established.
Arborists performing rigging operations shall be trained to estimate the potential forces at any point in the rigging system being used. The system components shall comply with working-load limits relative to the operation and the maximum potential forces.
Careful consideration shall be given to the potential for additional forces resulting from the influences of rigging design, rope angles, and the number of lines and/or line parts that will act on any rigging or anchor point.
A qualified arborist shall ensure that load ratings shown on the rigging equipment or provided by the manufacturer for all ropes, connecting links, and rigging equipment are observed in all rigging operations. Rigging equipment shall be chosen for the specific task based on working-load limits and design specifications. If a carabiner is used in a rigging system, loading of the gate and/or the minor axis of the carabiner shall be prevented.
The number of connecting links used for connecting components of a rigging system shall be minimized when possible. Arborists shall ensure that shackles, screw links, and other connecting links interface properly and are in compliance with manufacturers’ recommendations.
All equipment used for rigging operations shall be in good working condition. Rigging equipment and its connecting links shall be inspected immediately before use and removed from service if found to be defective, damaged, or overloaded.
When the potential exists for rigging equipment to be confused with climbing equipment, the equipment shall be clearly marked to indicate its different purposes.
When establishing a rigging point horizontally distant from the parent limb or main tree stem, the arborist should consider the need to provide additional support to help disperse the force of the proposed rigged load.
Options may include:
Workers aloft (either climbing the tree or from an aerial device) shall establish a communication system with arborists and other workers on the ground.
A method of verbal, audible, or visual communication shall be discussed and established during the job briefing prior to the start of removal or rigging operations. The verbal, audible, or visual communication system shall use an established command-and-response system (see example) or pre-arranged, two-way hand signals. The communication method shall be clearly understood and used during all rigging operations.
or
A drop zone shall be established prior to the start of rigging operations. Workers shall stay out of the drop zone until it has been communicated by a qualified arborist, a qualified arborist trainee, or the worker aloft directly involved in the rigging operation that it is safe to enter.
Only qualified arborists or qualified arborist trainees directly involved in the operation shall be permitted in the drop zone when a load is being suspended by the rigging system.
Taglines (line, tagline) or other means may be used to help control and handle suspended loads.
Ground workers involved in handling rigging lines shall not be underneath moving or suspended loads and should be out of the drop zone when practical.
Workers aloft shall position themselves above or to the side of the piece being rigged and out of the path of movement of the piece and attached rigging when the piece has been cut. Climbers shall have a retreat/escape plan prepared.
Climbers and their climbing systems shall not make contact with moving or swinging parts of the rigging system when making a release cut or when the load is moving. Rigging systems shall not compromise any part of the climbing system.
Steps shall be taken to prevent spars from splitting or tearing during the rigging operation, and climbers shall take steps to avoid trapping, pinning, or entangling themselves in the system should the tree split or the rigging fail. Load binders are one possible means of preventing splitting.
A hand saw shall be with a worker aloft to make or finish cuts.
Before beginning any tree removal operation, the chain saw operator and/or crew leader shall carefully consider relevant factors pertaining to the tree and site and shall take appropriate actions to ensure a safe removal operation. Factors to include may be, but are not limited to, tree decay, tree lean, and wind (see Annex C.3, Manual Tree Felling Procedure, for a more inclusive list).
The crew leader shall assess the number of workers necessary for the tree removal operations, develop a tree removal work plan, and communicate the work plan and job task assignments in a job briefing with the crew prior to beginning the tree removal work. In addition, a method of verbal, audible, or visual communication as set forth in Subsection 8.5.11 shall be discussed and established during the job briefing prior to the start of tree removal operations.
A drop zone shall be established prior to the start of piecing-down tree removal operations. Workers shall stay out of the drop zone until it has been communicated by a qualified arborist, a qualified arborist trainee, or the worker aloft directly involved in the piecing-down tree removal operation that it is safe to enter.
In manual tree felling operations, non-involved workers shall be positioned at a distance from the tree at least two (2.0) times the height of the tree or trunk being removed until the chain saw operator and/or crew leader communicates that it is safe to approach more closely. Involved workers other than the chain saw operator, including but not limited to those who handle ropes/taglines, come-alongs/winches, etc., shall be positioned at a distance from the tree at least one-and-one-half (1.5) times the height of the tree or trunk being removed until the chain saw operator and/or crew leader communicates that it is safe to approach more closely.
A planned retreat/escape path for all workers involved in the tree removal operation shall be prepared before piecing down tree parts or manual tree felling.
During manual tree felling, the preferred retreat/escape path for the chain saw operator is 45 degrees on either side of a line drawn opposite the intended direction of the fall.
To the extent practical, the retreat/escape path shall be cleared of obstructions and objects that would hinder retreat.
The chain saw operator shall use this path for egress once the felling cuts have been completed or the tree begins to fall.
Other involved workers shall have and use retreat/escape paths that do not hinder other retreating workers or expose any involved workers to increased hazard.
When it is necessary to use rigging to shorten or remove branches or to block down pieces of the tree, the qualified arborist shall consider whether the tree can withstand the strain of the lowering procedures. If the qualified arborist determines that the tree cannot withstand the strain of the lowering procedures, other means of removing the tree shall be implemented.
A rope should be attached to all trees and stems greater than 5 inches (12.7 cm) in diameter at breast height (dbh) being felled to provide stabilization and/or directional pull where assisted directional felling is required.
When there is a risk of damage to property from a tree piece or tree falling in an unintended direction, rope(s), block and tackle, come-alongs/winches, wire cable (except where an electrical hazard exists), or other appropriate devices shall be used to control the direction of fall.
Loaders, skid steers, or other heavy equipment shall not be used to push over trees that are being manually felled while any worker is within 1-1/2 times the height of the tree being felled. The heavy equipment being utilized shall be of the appropriate size for the task and shall offer appropriate protection for the operator.
Wedges should be used when determined to be necessary to prevent binding of the guide bar or chain when felling trees or stems. Wedges may be used as an aid in directional tree felling.
All equipment used for tree removal operations shall be in good working condition. Tree removal equipment and its connecting links shall be inspected immediately before use and removed from service if found to be defective, damaged, or overloaded.
Tree limbs shall be removed to a height and width sufficient to allow the tree parts or tree to fall clear of hazards, such as utility wires and/or other objects in the vicinity.
During manual tree felling operations, notches shall be used on all trees and trunks greater than 5 inches (12.7 cm) dbh.
When manually felling trees, notches and back cuts shall be made at a height that enables the chain saw operator to safely begin the cut, control the tree or trunk, and have freedom of movement toward a retreat/escape path.
The two cuts that form the notch shall meet at a point called the apex and shall not cross that point or go beyond the point where they meet.
The notch cut used shall be an open-face notch, a conventional notch, or a Humboldt notch.
Notches shall be 45 degrees or greater and wide enough to guide the fall of the tree or trunk.
Notch depth should not exceed one-third the diameter of the tree.
Saw cuts made to form the notch and back cut shall leave suitable hinge wood to adequately control the fall of the tree.
With an open-face notch (greater than 70 degrees), the back cut should be at the same level as the apex of the notch. With a conventional notch or Humboldt notch, the back cut shall be 1 to 2 inches (2.5 to 5 cm) above the apex of the notch to provide an adequate platform to reduce kickback potential of the tree or trunk.
The hazard of barber chair should be considered when cutting trees under tension. Steps to prevent the sudden splitting of trunk wood should be taken. Preventive steps may include, but are not limited to, various back cut methods; wrapping a ratchet strap, rope, or chain around the tree above the notch and back cut area; or relieving the tension in or on the tree by slackening pull ropes or removing upper parts of the tree prior to felling.
Before making the back cut, there shall be a command such as “stand clear” from the arborist operating the chain saw and a response such as “clear” from the workers supporting the removal operation. Pre-arranged, two-way hand signals or two-way audible devices such as air horn or whistle signals may also be used. Only designated persons shall give such signals.
During manual tree felling operations, involved workers shall keep visual contact with the tree or trunk until it is on the ground.
When the tree or trunk begins to fall, the worker at the base of the tree shall immediately move a safe distance away from the tree or trunk using the retreat/escape path.
Workers shall not approach closer than manufacturers’ or employers’ specified distances to mechanical operations, such as a rotary or flail mower, or boom-mounted saws, until all cutting has halted and the equipment operator has acknowledged that it is safe to do so.
Prior to the start of chipping operations, vehicular and pedestrian traffic control around the work zone shall be established in accordance with applicable local, state, or federal requirements. See Section 3.5, Traffic Control.
Brush and logs shall be placed in such a way that does not create hazards in the worksite.

Only persons authorized by the employer shall perform maintenance (see Annex C, General Safety Procedures That Apply to All Tree Work).
During chipping operations, hands, feet, or other parts of the body shall not pass beyond the plane of the infeed hopper. Leaning into or pushing material into infeed hoppers with feet is prohibited.
When hand-feeding a chipper, brush and logs shall be fed into chippers from the side of the feed table center line. Brush and logs should be fed butt or cut end first, and the operator shall immediately turn and step away from the feed table when the brush is taken into the rotor or feed rollers.
When hand-feeding a chipper during roadside operations, the operator should work from the curb or shoulder side whenever practical to prevent himself/herself from stepping into traffic or being pushed into traffic by the material that is being fed into the chipper.
Brush chipper discharge chutes shall not be removed nor shall the cutter housing cover be opened or raised while any part of the chipper is turning or moving. Chippers shall not be used unless a discharge chute of sufficient length or design is provided that prevents personal contact with the blades (see Annex C, General Safety Procedures That Apply to All Tree Work).
Material, such as stones, nails, or sweepings shall not be fed into chippers.
Limbs, logs, brush, and other woody material should be cut/prepared prior to feeding into the chipper.
Small vegetation shall be fed into chippers with longer branches or pushed with a longer branch, push paddle, or suitable non-metallic tool.
During chipping operations, operators shall be aware of potential pinch hazards between the machine and materials being chipped, and within the material itself.
When using a winch in chipper operations, the winch line and/or winch line hook shall never pass beyond the plane of the infeed hopper. Once the material is controlled by the feeder wheels, the feeding process shall be stopped and the winch line and/or hook shall be properly stowed before proceeding.
Should the chipper become clogged, procedures for the Control of Hazardous Energy (Annex C.2) shall be referenced and followed as appropriate.
Due to the hazards of step and touch potential, if the distance between the aerial device and energized conductor(s) is unintentionally less than the required minimum approach distance (MAD), workers on the ground shall move away and remain clear of the aerial-device vehicle and attached equipment (e.g., chipper) until the required MAD is reestablished.
Refer to Section 5.3, Brush Chippers, for additional information.
Specialized material handling equipment, such as but not limited to skid-steers or mini-loaders (whether wheeled or tracked), when used in chipping operations, shall not create a hazard for other workers.
Work plans for limbing and bucking operations shall be communicated to all workers in a job briefing before work begins.
When more than one worker is involved in limbing, bucking, and moving debris from a tree, each shall be positioned and their duties organized so that the actions of one worker will not create a hazard for any other worker. Only one worker shall be cutting a single tree or single tree part during the limbing and bucking process.
Before bucking or limbing wind-thrown trees, precautions shall be taken to prevent the root ball or butt log from striking a worker.
Chain saws should be operated away from the vicinity of the legs and feet. Natural barriers, such as limbs between the saw and the body, should be employed where possible. While operating a chain saw, the preferred working position is on the uphill side of the work.
The worker shall ensure firm footing before and during limbing and bucking. The worker shall not stand on loose debris or logs that may roll when the log being bucked is cut.
Trees, limbs, or saplings under tension shall be considered hazardous. Appropriate cutting techniques and precautions shall be followed.
When necessary to prevent rolling, logs shall be blocked with wood or other suitable material.
Wedges should be used as necessary to prevent binding of the guide bar or chain when bucking.
Cant hooks or peaveys should be used as an aid in rolling large or irregular logs.
If mechanized equipment is used, the equipment operator shall establish an effective means of communication with other workers (see Subsection 8.5.11).
