Formosa Plastics Industrial Explosion


Industrial Fires and Explosions

Industrial fires and explosions are usually determined to be accidents.  When an incident occurs in industry the investigation and analysis are done by some of the best and brightest engineers in the world. One of the many cases I have worked on involved an industrial explosion with 5 fatalities in Illiopolis, Ill.  This case ties into poor management decisions as a root cause and therefore has the most relevance to this management information systems class.  Attached below are summary points from the Investigation of the U.S. Chemical Safety and Hazard Board (CSB).
 

      The U.S. Chemical Safety and Hazard Investigation   Board (CSB)   INVESTIGATION REPORT
 
       REPORT NO. 2004-10-I-IL

       MARCH 2007

       VINYL CHLORIDE MONOMER EXPLOSION

                     (5 Dead, 3 Injured, and Community Evacuated)

        On April 23, 2004, an explosion and fire at the Formosa Plastics Corporation, Illiopolis, Illinois, (Formosa-IL) polyvinyl chloride (PVC) manufacturing facility killed five and severely injured three workers.
        The explosion and fire destroyed most of the reactor facility and adjacent warehouse and ignited PVC resins stored in the warehouse.
        Vinyl chloride monomer (VCM), a highly flammable chemical and known carcinogen and the primary raw material in the PVC manufacturing process, was the fuel for the explosion and initial fire.
        Formosa-IL, a wholly owned subsidiary of Formosa Plastics
        Corporation, USA (FPC USA), bought the Illiopolis facility from Borden Chemical and operated it for approximately two years before the incident.
        The U.S. Chemical Safety and Hazard Investigation Board (CSB) determined that this incident occurred when an operator drained a full, heated, and pressurized PVC reactor. The CSB believes that the operator cleaning a nearby reactor likely opened the bottom valve on an operating reactor, releasing its highly flammable contents.
        Opening the bottom valve on the operating reactor required bypassing a pressure interlock. The safeguards to prevent bypassing the interlock were insufficient for the high risk associated with this activity.
        Two similar incidents at FPC USA PVC manufacturing facilities highlight problems with safeguards designed to prevent inadvertent discharge of an operating reactor.
        Two operators working with the shift supervisor attempted to manage the release, did not evacuate, and subsequently died.
        The CSB determined that facility emergency procedures for evacuation were ambiguous and that facility staff had not conducted a large release emergency drill in more than 10 years.
        When FPC USA bought the Borden facility in 2002, management reorganized and reduced staff.
        Interviews and documents obtained by the CSB investigators indicate that when considering what changes to make, FPC USA compared similar Formosa plant sites and Formosa operating philosophy, but conducted no formal managerial or human resource analysis of the staffing changes. These changes occurred on the day Formosa-IL took ownership of the plant.
        Borden Chemical had assigned operators and a group leader (a working supervisor) for each area (such as PVC1).
         The group leader was an hourly employee responsible for supporting the operators in his/her area.
        Employees interviewed indicated that the group leader, a respected position at the Illiopolis facility, had an elevated level of responsibility.
        FPC USA management eliminated the group leaders when it bought the facility.
