On October 30, 2024, an employee was participating in a pack test (a physical fitness test for employment designed to test the capacity of the employee for arduous work, consisting of a timed 3-mile hike with a 45-pound pack over level terrain). He was about 40 minutes into the test when he felt severe back pain and cramps in his legs and became unconscious. The employee sustained a compression fracture of the T12 vertebra.
