Summary
A 2.3 kg chain assembly fell 10 m during lowering, grazing a worker’s helmet without injury. Wind displaced a soft sling, whose fibres prevented the hook latch from locking. The flash highlights unsafe positioning, poor visibility and absent communication, recommending correct rigging placement, clear lifting areas and supervision.
