Abstract
The National Institute for Occupational Safety and Health (NIOSH) responded to a health hazard evaluation (HHE) request from the U.S. Department of the Interior. The request pertained to cases of musculoskeletal disorders of the upper and lower extremities and back among workers who build and maintain the back country trails of Yosemite National Park. NIOSH investigators reviewed available accident and injury records for the years 1995-97, interviewed workers, and evaluated the trail construction projects for ergonomic risk factors. The ergonomics evaluation included analyzing videotape and still photo records of workers performing their jobs, and applied forces required to maneuver rocks with a lever bar. NIOSH investigators concluded that the job tasks associated with building and maintaining hiking trails at Yosemite National Park include many ergonomic stress factors that can lead to musculoskeletal disorders of the back and upper and lower extremities.
