摘要: In response to the large number of unintentional releases of hazardous materials from railroad tank cars for which accidents were not the cause, the Federal Railroad Administration (FRA) initiated this study to (1) recommend procedures to ensure that tank car appurtenances are properly maintained and secured, (2) develop and recommend cost effective procedures for monitoring and controlling tank car corrosion, and (3) investigate the issue of 'excess flow valves on propane cars not operating properly when the valve above it is sheared off. Leaks due to frangible disk failure were not included in the scope of this study. The study included review of all relevant literature, analysis of FRA Hazardous Material Inspector's reports, analysis of the Hazardous Materials Information System (HMIS) database maintained by the Research and Special Programs Administration (RSPA), and visits to tank car loading/unloading facilities and repair facilities. In addition, the University of New Brunswick conducted tests of Emergency Shut-off Valve (ESV) equipped propane cars.
