Hazardous Materials Accident Report - Hazardous Materials Release Following the Derailment of Baltimore and Ohio Railroad Company Train No. SLFR, Miamisburg, Ohio, July 8, 1986

摘要

The National Transportation Safety Board determines that the probable cause of the uncontrollable release of phosphorus was the failure of the unprotected bottom brake support attachment during the derailment resulting in the tearing of the tank shell. Contributing to the rupture of the tank was the Federal Railroad Administration's failure to require retroactively that reinforcement pads be installed between tank shells and welded attachments.
