I would like to hear your opinion about an observation that I made at a dairy plant. The way that the milk crates are moved from the refrigerated warehouse inside delivery trucks is by stacking the crates 4-5 high and then pulling them with some metal hook and dragging them on the floor and into the truck. There have been several shoulder and back injuries from this practice and I was wondering if there is a better way to do this kind of work. The floor is fairly smooth to make it easier to drag the crate stacks and it looks like this is common practice. Any thoughts/comments on how to improve the process and prevent more injuries?
