Materials Regulations, 1s one that is permanently athxed to the Specification Cargo Tank vehicle and shows such things as the specification number, name of the tank manufacturer, tank manufacturer's serial number, dates of manufacture and test, and shell materials. The information on the plate varies according to type of tank vehicle. Of what value is the Specification Plate to the driverf The driver must check the Specification Plate to make certain that the tank is the type authorized to hold that specific HM to be loaded. If an incompatible material is loaded into a cargo tank, a hazardous situation may result. What is required with respect to “bonding” tank trucks? The Hazardous Materials Regulations require that an electrical bond wire be used during the filling/loading of a tank truck because the bond wire effectively grounds the vehicle during filling to prevent the build-up of static charges. A “drag chain” is not classified as an effective grounding device for this purpose. When transporting flammables, what type of emergency signal is forbidden to be used by the tank truck driver? A tank truck driver is forbidden to use any flame producing emergency signal when transporting flammables. What checks should the driver of a cargo tank vehicle make before starting to unload? In addition to all normal checks before unloading, the driver should be certain that the unloading line on the tank truck vehicle is connected to the proper fill-pipe of the particular storage tank to be filled. The driver should also be sure that the storage tank has sufficient capacity to accept the quantity of cargo to be unloaded. What are the hazards associated with unloading HM into the wrong storage tank? An inadvertent mixture of incompatible materials may result in the release of toxic fumes, and/or a possible increase in the danger of fire or explosion. A spill could result if the tank over- flows. 93
