Abstract: At approximately 9:38 a.m. on May 11, 2021, Employee #1, a groundsman and tree climber apprentice, was cutting a tree limb from a pear tree at a residential property using a Stihl 020 chainsaw. While standing on a ladder approximately 4 feet above the ground, the ladder shifted, causing Employee #1 to lose balance. As Employee #1 attempted to regain balance, his left arm came into contact with the running blade of the chainsaw, resulting in a severe laceration to his left wrist. The injury caused damage to muscles, tendons, and bone. The employee was hospitalized for more than two days and underwent two surgeries. The employer was cited for failure to ensure the chainsaw was operated in accordance with the manufacturer's instructions.
