Occupational ergonomics: theory and applications. Bhattacharya A, McGlothlin JD, eds. New York: Marcel Dekker, 1996 Apr; :259-277
Ergonomic job analysis was discussed in this chapter. Steps involved in performing an ergonomic job analysis depend partly on the purpose and scope of the study, but in general included identifying the potential hazards, preparing for the field study, conducting the field study, and interpreting the results. Potential hazards may be identified by reviewing injury data, and reviewing processes and job activities. When preparing for a job analysis it is necessary to gather the equipment needed in the field. It is also important to identify a strategy that will be used so that sufficient information is gathered to allow the analyst to completely describe the job as it is currently begin performed. During the conducting of the field study it is necessary to observe work processes, interview supervisors and employees, and take measurements. Interpreting the results calls for examining each of the tasks in terms of the following dimensions: forces needed to perform the task, postures assumed during the task, frequency of muscle activation, duration of work and recovery periods, and exposure to vibration and cold. In developing solutions, it is important to provide documentation of the suggestions. A job analysis example was provided.
