The U.S. Chemical Safety Board (CSB) released its findings and a safety bulletin entitled "Key Lessons for Preventing Incidents when Preparing Process Equipment for Maintenance" resulting from a hydrocarbon release and fire that injured one worker at the Delaware City Refining Company in Delaware City, DE. CSB Chairperson Vanessa Allen Sutherland said, "More than a third of the incidents investigated by the CSB occurred during maintenance activities, ultimately resulting in 86 fatalities and 410 injuries." On November 29, 2015, alkylation unit operators at the Delaware City Refining Company, or DCRC, were preparing equipment for maintenance. Prior to performing the work, operators had to first drain and isolate a section of piping scheduled to be replaced by closing valves to block the flow of hydrocarbons into the piping. However, the operators learned that a valve on one side of the pipe isolation was leaking and therefore would not seal properly, which led...
Preliminary findings from its ongoing investigation of the toxic chemical release that occurred at the MGPI Processing plant in Atchison, Kansas, on October 21, 2016 have been released by the Chemical Safety Board. The CSB’s investigation into the release has identified several shortcomings in the design and labeling of loading stations, as well as adherence to chemical unloading procedures. The MGPI facility produces distilled spirits and specialty wheat proteins and starches. The chemical release occurred when sulfuric acid was inadvertently unloaded from a tanker truck into a fixed sodium hypochlorite tank at the plant. The two materials combined to produce chlorine gas that sent over 140 individuals, both workers and members of the public, to area hospitals and resulted in shelter-in-place and evacuation orders for thousands of local residents. Chairperson Vanessa Allen Sutherland said, “This type of accident is preventable. Our investigation demonstrates all too clearly that complacency with...
