Abstract: At noon on May 15, 2012, an employee was working for a childrens hospital landscaping firm, that provided arborist services. The employee was trimming trees at the hospital and was speaking with one of the hospital's employee. They were discussing whom to notify for herbicide spraying treatment along nearby power lines later in the summer. The landscaping vehicle was idling on a hill and the employee was going to be taken into the hospital to speak with someone from the maintenance department. As the employee and the hospital worker got close to the door, the vehicle started moving down the hill. The truck hit a picnic table, which then struck the hospital employee. The table was pinned against the employee's upper legs and lower torso. Once the vehicle was removed, hospital staff began working on the employee and he died.
