  1. Rail Car 101

  2. Objective • Upon the completion of this module, participants will be able to describe rail transport of hazardous materials, focusing on denatured fuel ethanol.

  3. General Railroad Statistics Hundreds of operating railroads in the U.S. Tens of millions of railcar shipments each year Over a hundred thousand miles of track in U.S. Over a million railcars in service Over a hundred thousand employees

  4. Railroad Statistics for Hazmat Over a million loads of hazardous materials are shipped via rail Ethanol is over a quarter of total number of hazmat shipments About three-quarters of the transportation of ethanol is conducted via rail Ethanol is over one percent of all railroad shipments

  5. Initial Noticeable Characteristics http://www.phmsa.dot.gov/staticfiles/PHMSA/DownloadableFiles/Files/Hazmat/ERG2012.pdf

  6. Tank Car Body Stencil

  7. Tank Car End Stencil

  8. Bottom Outlet Stencil

  9. Placard Example Key characteristics: Placard color Hazard class UN number

  10. Ethanol Placarding

  11. Brakes • Hand • Holds the car in place • Prevents the tank car from moving and possibly causing further damage at incident site or harm to a responder • Air • If there is an incident, potential for a rapid release of air causing the hose and fittings to strike a responder

  12. Hand Brake

  13. Air Brake

  14. Brake Cylinder

  15. Double-Shelf Couplers

  16. Coupler

  17. Tank Car Wheels Separated from Tank Car

  18. Valves

  19. Vacuum Relief

  20. Top Operated Bottom Outlet Valve

  21. Bottom Outlet Valve

  22. Butterfly

  23. Manway

  24. Top Ethanol NAR Causes/Issues • Manway • Loose bolts • Gasket deteriorated/wrong type • Gasket misaligned • Gasket missing • Bottom outlet valve • Cap loose – Valve open • Cap loose – Valve closed

  25. Manway – Without Bolts

  26. Manway – Loose Bolts
