20-Year-Old Man Killed When Struck By Tree Falling from Tree-Cutting Machine
On February 9, 2004, a 20-year-old male landscaping worker was killed when he was struck by a falling tree. The victim worked for his father, the owner of a small landscaping business in New Jersey. On the day of the incident, the victim and several other workers were assigned to clear a plot of land that included many large pine trees. The victim’s job was to mark and clean already felled trees, which included cutting branches and reducing the size of the logs (bucking). While the victim was cutting the branches with a chainsaw, a tree-cutting machine was being used approximately 60 feet away to cut and clear the standing trees on the plot. This tree-cutting machine, similar to a front-end loader, was fitted with a specialized attachment referred to as a feller-buncher. The feller-buncher clasps the tree in hydraulic jaws, cuts the tree at its base, and enables the cut tree to then be transported. The fatal injury occurred when a cut pine tree came loose from the tree-cutting machine and fell, striking the victim. NJ FACE investigators recommend following these safety guidelines to prevent similar incidents:
On February 9, 2004, a federal OSHA compliance officer notified NJ FACE staff of a 20-year-old man who was killed in a tree-clearing accident. A FACE investigator conferred with the compliance officer and arranged to conduct a concurrent investigation, which took place on March 9, 2004. During the visit, FACE investigators were permitted to participate in the OSHA witness interviews and to examine both the tree-cutting machine and the scene of the accident (which had been cleared of all equipment and tree remnants). The area was photographed. Additional information was obtained from the police report, the medical examiner’s report, the OSHA investigation file, and the Arborist Association.
The victim’s employer is a family-owned landscaping and excavating business for which the victim worked at for several years. The victim, the owner’s son, was to soon take over several aspects of the business. The company employed ten workers, and five were present at the time of the incident, including the owner. Employee training was entirely on-the-job.

The incident occurred at a wooded site in a rural area in New Jersey. The site was a 100 foot x 100 foot plot of land (see Figure 1), that was to be clear-cut by the family-owned landscaping business. A construction company purchased the plot in April 2003, and hired the landscaping company to clear the trees to prepare the area for development. The landscaping company was to clear all trees within the 1000-square-foot area that was demarcated with yellow stakes. According to the owner, it was to take approximately two days to clear the lot. The majority of the clear cutting would take place on the first day. Work on the second day would entail using a chainsaw to cut the felled trees into approximately 17 foot logs and removing all branches, which would be chipped onsite.
The tree-cutting machine was a four-wheeled, diesel-powered tractor, similar to a front-end loader, with a specialized tree-cutting device, a feller-buncher, mounted on the front (see Figures 2 and 3). The specialized device, which was hydraulically operated, consisted of a large, rotating circular saw at the base (see Figure 4). Directly above the saw was a series of interlocking arms that could be opened and closed (see Figure 5). The tree-cutting machine was operated as follows: the operator positioned the feller-buncher at the tree, the saw blade was engaged, and the tree was cut and collected by the interlocking arms. The cutting and grasping were essentially two simultaneous actions. The feller-buncher was also fitted with a thick, forked extension (see Figure 6) above the interlocking arms that served to maintain a cut tree in an upright position and acted to prevent a cut tree from falling directly backward onto the cab.
The incident occurred on Monday, February 9, 2004 at about 10:00 AM. It was a mostly clear, cool day with a weather forecast that predicted gusts of wind. The tree-cutting machine operator arrived at the lot and began to cut and stack felled pine trees. The operator was well into the job when the remainder of the crew arrived. Hoping to get a head start on the clearing and cutting of the felled trees, the victim began bucking a felled tree approximately 60 ft from the tree-cutting machine. The machine operator approached a 70-foot tall pine tree with the tree-cutting machine, cut it and attempted to close the “claws” around the tree. However, according to the operator, a gust of wind caught the “twisted” top of the pine, which caused it to become free of the jaws. The cut tree fell uncontrolled at about a 45-degree angle back behind the cab of the machine, striking the victim in the back of the head. The other workers (including the victim’s younger brother, also an employee) attempted to provide assistance, and one worker called 911. Police and rescue workers responded. The victim was pronounced dead at the scene by telemetry.

Recommendation #1: All ground crew should always maintain a safe distance of at least twice the height of the felled tree from its cut point. If not feasible, consider staggering job shifts.
Discussion: According to OSHA logging Regulation 29 CFR 1910.266, all ground work should be done at a distance of least two tree lengths of the tallest tree being felled. This is critically important in any logging operation, such as the use of a tree-cutting machine. In this case, since the lot was only 100 feet by 100 feet, and the tree that fell was about 70 feet tall, a safe distance did not exist in the work area. In this case, an alternative solution would be to stagger the job shifts such that all bucking takes place either after all trees are felled, or only while the machine is not running.

Staff members of the New Jersey Department of Health and Senior Services, Occupational Health Service, perform FACE investigations when there is a report of a targeted work-related fatal injury. The goal of FACE is to prevent fatal work injuries by studying the work environment, the worker, the task and tools the worker was using, the energy exchange resulting in the fatal injury, and the role of management in controlling how these factors interact. FACE gathers information from multiple sources that may include interviews of employers, workers, and other investigators; examination of the fatality site and related equipment; and reviewing OSHA, police, and medical examiner reports, employer safety procedures, and training plans. The FACE program does not determine fault or place blame on employers or individual workers. Findings are summarized in narrative investigation reports that include recommendations for preventing similar events. All names and other identifiers are removed from FACE reports and other data to protect the confidentiality of those who participate in the program.
NIOSH-funded state-based FACE Programs include: Alaska, California, Iowa, Kentucky, Massachusetts, Michigan, Minnesota, Nebraska, New Jersey, New York, Oklahoma, Oregon, Washington, West Virginia, and Wisconsin.
