Ergonomics is the study of work in relation to the environment in which it is performed (the workplace) and those who perform it (workers).It is used to determine how the workplace can be designed or adapted to the worker in order to
prevent a variety of health problems and to increase efficiency; in other words, to make the job fit the worker, instead of forcing the worker to conform to the job. Ergonomics examines the physical capabilities of the human body and the
limitations of the human body in relation to a person’s work tasks, the tools used and the job environment. Meyers et al. (1998) has cited three general risk factors as both endemic and of highest priority throughout the agricultural industry.
They are: lifting and carrying heavy loads, sustained or repeated full body bending (stoop) and very highly repetitive hand work (clipping, cutting).
