Abstract: At approximately 7:00 a.m. on July 22, 2013, Employee #1, a rail clerk with Total Terminal International, began her work with a headache. She was working alone in the terminal's rail yard, where she documented containers entering and leaving the terminal by rail. As the day continued, Employee #1's headache worsened, until she could not continue to work. Employee #1 informed her supervisor that she could not continue to work because of her headache and that she thought the headache might be caused by her high blood pressure. Employee #1"s supervisor notified paramedics that an employee might possibly be suffering from a stroke, and paramedics transported Employee #1 to the hospital, where Employee #1 was hospitalized. At the hospital, Employee #1 was diagnosed with bacterial meningitis. In a subsequent investigation, it was determined that the cause of the illness was not work-related, and the investigation involving Total Terminal International was closed.
