If the worker at the bottom of this photo seems to be straining as he hoists a heavy bucket full of material, imagine the strain on the worker above him who is trying to haul it to the top of this platform. Any number of things could go badly here. The worker taking the load could lose his grip and drop it on his co-worker. Worse, he could lose his balance and he and the load could crash down on the other worker. At the least, the elevated worker’s poor lifting position could easily leave him with a back injury. Any way you look at it, it’s not a pretty picture. (Elcosh)
