No matter what scenario is developed, or what equipment is obtained, it has weaknesses and costs. In my opinion, the best-spent money is for dependable, consciencious workers. If management does their job to develop and maintain a good program with good working conditions, you only need attentive employees that have appropriate training. That is were I would spend my money.
Over the years, I have seen many problems thwarted by attentive staff. Good staff will help you select equipment appropriate for your facility (and possibly at reduced cost). Good equipment enhances the worker, but the best equipment in the world will not stop all incidents when the users are inattentive or poorly trained. Equipment that is too high-tech and costly sometimes causes workers to lose their "ownership" of a job, thus decreasing their effectiveness.
