| Abstract: | Twenty evaluations of reported biomechanical hazards were performed by the National Institue for Occupational Safety and Health (NIOSH) at the request of industrial workers or management over an 8-year period. The evaluations were part of the Hazard Evaluation and Technical Assistance (HETA) program authorized under the Occupational Safety and Health Act of 1970. A number of these evaluations are described here. Principles drawn from the field of ergonomics were used to evaluate whether a certain work activity has caused an observed incidence of cumulative trauma to the neuro-musculo-skeletal system. Procedures for conducting these ergonomic evaluations are reviewed, and the results are summarized. Recommendations are made for implementing control procedures, and the problem of obtaining reliable follow-up information is discussed. Project results suggest an encouraging degree of success in accomplishing prevention and control of biochemical hazards in the workplaces studied. |
