Summary
Investigation of a rigger trapped between a rolling muffler and scaffold during butterfly-valve lifting. The report identifies inattention, pinch-point exposure, insufficient mounting bolts and slip bracing, with vessel movement a possible contributor. The blind lift used radio communications and signalmen; the worker sustained a hairline shoulder-blade fracture.
