Trees require regular maintenance to ensure their health and safety. Dead or diseased trees must be cut down in order to prevent injuries to people or damage to nearby structures. Maintaining trees through trimming is a dangerous task, even for experienced professionals. Unfortunately, accidents do occur. The three most common types of serious accidents experienced by tree trimmers are falls, electrocution, and being struck by falling objects.

Falls

Falls are a common accident for tree trimmers. They can occur by slipping off of a ladder, falling from a roof, or falling out of a tree. The typical fall victim is unsecured or not properly secured. Using proper personal protective equipment is essential in preventing falls.

Electrocution

The risk of electrocution is very high when working around power lines. Some trees are planted near overhead power lines and there is a risk of electrocution to anyone trimming branches. The worker may accidentally touch the wires, or a falling branch could knock down the wires resulting in a tree trimmer touching the lines. The most common type of victim violates minimum approach distances and makes contact with the power lines through a conductive tool/object such as pruning shears. Training employees on minimum approach distances and proper trimming techniques when working around power lines can help prevent electrocution.

Falling Objects

According to the Centers for Disease Control, being struck by a falling object is the most reported tree trimming accident. A falling object is typically an entire tree or its branches/limbs, but it could also be loose equipment like a chain saw. Most victims are struck by a tree or tree limb after it falls in an unexpected direction; however, careless accidents do occur in specified drop zones. Communication between employees in the tree and on the ground is imperative to ensure the safety of all.

Tree trimming professionals face dangerous hazards on a daily basis and it is extremely important to take precautionary safety measures to make sure that they are doing everything they can to reduce risk. Safety training materials for tree trimmers are available through the Risk Management Center.
