Southwest Research Institute (SwRI) has helped determine the viability of pressure relief valves for liquid natural gas tanks in the event of a train derailment for the Federal Rail Administration (FRA). The report from the FRA shows that a study conducted by SwRI demonstrates that the pressure relief valves work as designed to prevent overpressurization and explosion if a derailment occurs.
