STUDY OF PROBLEMS ASSOCIATED WITH BOTTOM LOADING OF FLAMMABLE LIQUIDS IN CARGO TANK MOTOR VEHICLES

A study of the problems associated with bottom loading of flammable liquids in cargo tank motor vehicles is announced. The study will review the mechanical aspects of bottom loadings with regard to the devices and procedures for removing flammable liquid products from loadinglines under tanks and the protection of those lines from underride accidents. The study will also review specifications of liquid level sensing devices with particular emphasis on the following: safety characteristics, comparison of different systems used from tank vehicles to loading terminal, construction of fail-safe features into the systems, an longevity of the systems. Based on the results of this study, recommendations will be made related to reducing the fire hazard potential from liquid lines in underride accidents, and the effectiveness will be evaluated of the liquid level sensing devices.
