Slosh Characteristics of Intermediate Bulk Containers (IBCs)

The objective of this project was to determine the slosh characteristics of intermediate bulk carriers (IBCs) with a combined capacity of up to 1,000 gallons through engineering modeling and road testing. An IBC can hold 119–884 gallons of liquid. The results from the engineering modeling and road testing were used to determine if the slosh characteristics of IBCs aggregated to 1,000 gallons are similar to a single or compartmented cargo tank of the same capacity. In the final rule on commercial driver’s license (CDL) testing and commercial learner’s permit standards published on May 9, 2011, the Federal Motor Carrier Safety Administration (FMCSA) revised the definition of “tank vehicle” to include any commercial vehicle transporting tanks (to include IBCs) of liquids or gases with an aggregate of 1,000 gallons or more. The revision of the definition of “tank vehicle” implies that a person driving a commercial vehicle carrying an aggregate of 1,000 gallons or more of liquids or gases in IBCs must hold a CDL with a tank vehicle (N) endorsement. Previously, drivers of such vehicles were not subject to this requirement. Engineering modeling and road testing were undertaken to ascertain whether the slosh characteristics of IBCs aggregated to 1,000 gallons or more are similar to a single or compartmented cargo tank of the same capacity. The results of this testing were considered in determining whether there was a need to revise the existing rule on tank vehicle endorsements.
