On the morning of February 2, 2016, a 44-year-old elevator repair technician working for Slade Elevator was accidentally killed inside an elevator shaft of Tower II while doing scheduled monthly maintenance on that elevator. The worker became entangled between the elevator door and the upper portion of the elevator car and was dragged upwards. He was pronounced dead at the scene. While Occupational Safety and Health Administration embarked on an investigation to determine the worker's official cause of death, the building's management stated publicly that while there was no indication that this was caused by an elevator malfunction, the elevators would be operated entirely by attendants, and their automatic functions suspended, until their safety could be verified through inspection.
