I hope that during the investigation Cargill retains all of the machinery involved. In a pump or pipe failed then that has to be investigated. Who manufactured the pump? Was it done correctly? Did they use inferior metals that gave way to the heat. There are a ton of standards that must be met in manufacturing these types of systems. If those standards weren't met then due to some company trying to cut costs, then someone needs to be held responsible for these workers' injuries.
