The spillage of liquids in bulk quantities during transportation is examined from the viewpoint of the risk reduction which will result from improved vehicle roll stability. Roll stability limits were first computed for conventional vehicles used currently by the Rohm and Haas Company to transport chemical waste products. The vehicles in question included tractor-semitrailer combinations having both van- and tank-type trailer configurations. The stability level of individual vehicles was related to a national rate of rollover risk, expressed in rollovers per million miles of travel. The risk projections were based upon an evaluation of accident and exposure information generated through a detailed survey program undertaken previously. Improvements in suspension selection, height of the payload center of gravity, and tractor axle width were also examined by means of the stability analysis. When used in combination, such improvements were seen to reduce the rollover risk by as much as 35% relative to Rohm and Haas' current equipment. The problem of fluid slosh occurring when a bulk tanker is underfilled was also considered by reference to existing literature.
