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

Ethanol Placarding
Ethanol Concentration Preferred Proper Shipping Name
E1 to E10 Gasohol, UN 1203 or Gasoline, UN 1203
E11 to E94 Ethanol and Gasoline mixture, UN 3475
E95 to E99 Denatured Alcohol, NA 1987 or Alcohols n.o.s., UN 1987
E100 Ethanol, UN 1170 or Ethyl Alcohol, UN 1170

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
