Abstract: On October 7, 2012 at about 6:13 AM, Employee #1 fell approximately 10 ft from a jetway passenger boarding bridge while standing on it. Employee #1 stated she was going to the ticket counter from Gate 21 via a jetway bridge. The jetway bridge is an enclosed movable walkway on the wheels, about 11 ft high above the ramp which connects to the air craft and the terminal. Employee #1 stated that it is a common practice for the employees to use the stairways attached to the jetway bridge located at Gate 21 as a short route to go to the ticket counter from the terminal. When Employee #1 was on the jetway bridge, she noticed that a coworker was driving the jetway bridge away from the aircraft. At this point, Employee #1 stood against the wall of the jetway bridge next to the roll up door. Employee #1 was attempting to inform her coworker that the bridge was not aligned correctly, and somehow her foot slipped off the jetway-bridge and she fell onto the tarmac. As a result, Employee #1 suffered serious injuries and was hospitalized for more than 24 hours with multiple fractures on left femur and left ankle.
