Hazardous Materials: Notice of Updated Rail Tank Car Thermal Protection Systems List

Notice and request for comments.

The Pipeline and Hazardous Materials Safety Administration (PHMSA) issues this notice in coordination with the Federal Railroad Administration (FRA) to notify the public of four systems that have been added to the thermal protection systems list since its most recent publication, as well as to solicit comments or updates to information on the current list. The thermal protection systems included on the list are compliant and are acceptable for use, without further test verification, on U.S. Department of Transportation (DOT) specification tank cars. DOT manages the list through the PHMSA Records Center and periodically publishes an updated list in the Federal Register for public awareness.
