Field jobs (harvesting,weeding, irrigating, cultural practices, etc.) remain demanding physical tasks, involving stooped postures, lifting and carrying, and repetitive hand work.Meyers et al. (1996) suggested these three priority risk ergonomic factors as of general concern in California agricultural work. Research has shown that many important risk factors can be successfully addressed in agricultural work using ergonomic approaches (Lundqvist 1992; Lundqvist et al. 1992; Wick
1992; Miles and Steinke 1993; Meyers and Miles 1996, 1997).
