Description
Summary:Objectives: The study objective was to characterize work methods, hazards and annual hazard exposure hours of three silage storage methods. Methods: A telephone questionnaire was designed and administered to 24 Wisconsin dairy managers. The exposure durations reported were scaled to a standard-sized dairy herd with equal dry matter tons of silage stored and fed each year. Results: Managers reported no silo gas hazards with either bunker or bag silos. Compared to tower silos, managers reported reduced fall hazards with bunker silos and no fall hazards with bag silos although both introduced front end loader operation injury hazards. Compared to bunkers, managers who used bag silos reported no exposure to tractor overturns. Conclusions: Although some hazards are clearly present using any ensling method, dairy farms that adopt silage bag technology can reduce many of the hazards traditionally associated with silage work.
