This month we are discussing Charles Perrow’s book Normal Accidents that addresses the risks associated with complex, tightly coupled high-risk technological systems. Through analyses of numerous accidents and incidents involving nuclear power plants, petrochemical plants, aerospace and maritime systems, and others, Perrow derived a framework that showed how high-risk systems are prone to accidents if they are highly complex and the components are tightly coupled. He also argued that efforts to improve safety such as more meters and indicators can have the opposite effect of complicating the operator’s ability to control a catastrophic situation.
