Abstract
To prevent medical problems associated with physical exertion required in materials handling operations, over 900 jobs in 6 plants were evaluated via medical examination and isometric strength tests obtained in several postures, to establish the relative strength requirements of each job. The major findings of the study are: the activity of lifting heavy loads, especially when done frequently, is associated with increased numbers and severity of musculoskeletal incidents; weaker workers when performing high strength requiring activities, have an increased incidence and severity of musculoskeletal and contact type injuries; strength varies greatly in the working population and is not well predicted based on gender, age, body weight, or stature, strength which relates to personal risk of later injury can be equally assessed by testing a worker in postures which are standardized or which reflect the maximum load related postures required on the job. New in-depth biomechanical and metabolic job evaluation methodologies are also employed on selected jobs which demonstrate how re-engineering could be accomplished to reduce the potential for different types of musculoskeletal injuries. Recommendations are proposed for the development of an action level to control the hazards of excessive physical exertion for weaker workers, and type of strength testing. (Contract No. 099-74-0062)
