摘要

The following is my opinion of the events that led to this explosion as testified to in open court. Others may have different opinions.rnA few years ago, there was an explosion in a reactor at the XYZ Chemical Company that resulted in the death of two workers. The reactor was a block copolymerization reactor where butadiene and styrene monomers were added in a semi-batch manner. The heat of reaction was removed by means of a refrigeration system. The incident occurred when the reactants were not added in the sequence or quantity desired. The resulting runaway reaction overpressurized the reactor system and caused an expansion joint to rupture. The hydrocarbons released formed a vapor cloud that exploded, causing the death of two workers, serious injury to three others and significant damage to the facility.rnThe contributing causes of the incident included most of the Process Safety Management (PSM) elements developed by the Center for Chemical Process Safety of the American Institute of Chemical Engineers in 1989 and codified by OSHA in 1992 in the Process Safety Management Regulation in 1992: lack of information about the hazards of the chemicals in the process; lack of information about the equipment in the process and inadequate equipment; inadequate or no PHA; inadequate training; confusing operating procedures; failure to use management of change procedures; failure to perform a pre-startup safety review; failure to have an adequate contractor safety program and failure to investigate previous near misses and incidents and take corrective actions. The root cause was that the XYZ Chemical Company chose to have an inadequate PSM program; they chose to do no more than they needed to do to appear to be in compliance with OSHA's PSM regulation.
