The National Transportation Safety Board makes the following

safety recommendations to the Pipeline and Hazardous

Materials Safety Administration:

 

Require that all newly manufactured and existing general

service tank cars authorized for transportation of denatured

fuel ethanol and crude oil in Packing Groups I and II have

enhanced tank head and shell puncture resistance systems and

top fittings protection that exceeds existing design

requirements for DOT-111 tank cars. (R-12-5)

 

Require that all bottom outlet valves used on newly

manufactured and existing non-pressure tank cars are

designed to remain closed during accidents in which the

valve and operating handle are subjected to impact forces.

(R-12-6)

 

Require that all newly manufactured and existing tank cars

authorized for transportation of hazardous materials have

center sill or draft sill attachment designs that conform to

the revised Association of American Railroads' design

requirements adopted as a result of Safety Recommendation R-

12-9. (R-12-7)

 

Inform pipeline operators about the circumstances of the

accident and advise them of the need to inspect pipeline

facilities after notification of accidents occurring in

railroad rights-of-way. (R-12-8)

 

The National Transportation Safety Board reiterates the

following previously issued safety recommendation to the

Pipeline and Hazardous Materials Safety Administration:

 

With the assistance of the Federal Railroad Administration,

require that railroads immediately provide to emergency

responders accurate, real-time information regarding the

identity and location of all hazardous materials on a train.
