Evaluate, with the assistance of FRA, AAR, and the Railway Progress Institute, the deterioration of pressure relief devices through normal service and then develop inspection criteria to ensure that the pressure relief devices remain functional between regular inspection intervals. Incorporate these inspection criteria into the U.S. DOT Hazardous Materials Regulations.

original
NTSB letter

In cooperation with the Occupational Safety and Health Administration and the Environmental Protection Agency, develop regulations that require safe operating procedures to be established before hazardous materials are heated in a railroad tank car for unloading; at a minimum, the procedures should include the monitoring of internal tank pressure and cargo temperature.

"Periodic
inspection &
testing of rail
tank cars"
original
NTSB Letter
12/31/92
|
Develop and promulgate, with
FRA, requirements for the
periodic testing and inspection of
rail tank cars that help to ensure
the detection of cracks before
they propagate to critical length
by establishing inspection
intervals that are based on the
defect size detectable by the
inspection method used, the
stress level, and the crack
propagation characteristics of the
structural component
(requirements based on a
damage-tolerance approach). |
Research by FRA and industry
is on-going. |
