There has been an increase in the number of claims resulting from carpal tunnel syndrome and from musculoskeletal and tissue diseases, which are caused by repetitive trauma that usually affect workers' shoulders and upper extremities. The third portion of Table 6 shows the part of the body affected by the injury event. The back remains the most frequent body part injured. The final portion of the table shows the object that directly caused the injuries or diseases. Floors, walks, and the ground are usually the sources of injury in falls, although workers also fall onto other items.
Containers are most often the sources of injury in overexertion claims.
In four percent of the cases, another person is the direct cause of the injury. This type of claim excludes temporary disability suffered during the first three calendar days after the employee leaves work as a result of the injury or disease, unless the worker is a hospital inpatient or dies. If the employee leaves work the day of the injury, that day is considered the first day of the three- day period. The claims rate is the number of accepted disabling claims per 100 workers. The fatality rate is the number of accepted fatality claims per 100,000 workers.
