Hoisting a heavy bag of tools via rope to a higher level at a worksite requires planning and a firm footing—qualities that are certainly not evident in this worker's method. He is leaning over the edge of a building's roof, many feet above the ground, with no fall protection gear in sight. It wouldn't take much for him to tumble over the edge, with dire consequences for himself and anyone else in his path. (WorkSafe Victoria, Australia)
