The CSB issues safety recommendations to prevent the recurrence or reduce the likelihood or consequences of similar incidents or hazards in the future. Recommendations are issued to a variety of parties, including government entities, safety organizations, trade unions, trade associations, corporations, emergency response organizations, educational institutions, and public interest groups. Recommendations are published in CSB reports and are closed only by vote of the Board. The CSB tracks all recommendations and communicates regularly with recommendations recipients to ensure that the recommended corrective actions are implemented.

Emergency Shutdown Systems for Chlorine Transfer (1 Recommendations)
Department of Transportation (DOT) (1 Recommendations)
Open: 0% | Closed: 100%

Final Report Released On: June 14, 2007


Expand the scope of DOT regulatory coverage to include chlorine railcar unloading operations. Ensure the regulations specifically require remotely operated emergency isolation devices that will quickly isolate a leak in any of the flexible hoses (or piping components) used to unload a chlorine railcar. The shutdown system must be capable of stopping a chlorine release from both the railcar and the facility chlorine receiving equipment. Require the emergency isolation system be periodically maintained and operationally tested to ensure it will function in the event of an unloading system chlorine leak.

Status: Closed - No Longer Applicable
