Safety Advisory: Unauthorized Cargo Tanks Used To Transport Hazardous Materials

Notice of identification of unauthorized cargo tanks.

This notice identifies unauthorized cargo tanks and removes them from service. The FMCSA has identified non-conforming cargo tanks as the result of compliance reviews assessing compliance with Hazardous Materials Regulations. This action notifies tank owners that these tanks are not authorized to transport hazardous materials, and ensures their removal from service. The FMCSA notifies the public that MC-331 cargo tank motor vehicles assembled with designs T-5314, certified 3- 10-1997 and T-5602-A, certified 9-12-1997 by Chemical Transportation Engineering Consultants, Inc., Lubbock, TX do not meet the minimum design requirements for a specification cargo tank and are no longer authorized to transport hazardous materials requiring a specification package. These tanks are no longer authorized because the rear end protection devices for these cargo tanks do not meet the minimum regulatory requirements. There is a high probability that a failure of these devices could occur during a rear end collision resulting in serious injury, death and property damage.
