. What are the consequences of inadvertently overfilling a storage tank? The hazards of overfilling a storage tank will vary with the nature of the product, and could cause a fire. In addition to the loss of product, overfilling a storage tank ts likely to result in environ- mental damage and require costly clean-up measures.. What information on shipping documents must a driver check before transporting a load of hazardous materials in a tank vehicle? It is a violation of the regulations for a carrier to accept hazmat that ts not properly described on the shipping papers. Since the driver is the carrier's “agent” at the loading site, the driver must check informa- tion (on shipping documents) such as: U_N. identification number, proper commodity description, hazard classifications — flamumable liquid, corrosive, etc., — packing group, and total quantity by weight or volume and the number and type of packages/drums.. What must be done with the hazardous materials placards ona cargo tank after its HM cargo has been unloaded?f The placards must be left in place until the vehicle is purged to remove all HM residues.. What special checks of a tank vehicle transporting HM must be made as a part of the driver's pre-trip inspection? ‘The driver must be sure that all valves and unloading lines are securely closed and that manholes are closed to prevent the loss of cargo. ‘The driver should also check for any signs of leakage elsewhere on the vehicle.. Why ts it particularly important to avoid any sudden steering maneuvers When driving a cargo tank vehicle? Sudden turning movements cause “liquid surge.” As the contents of the cargo tank move from side to side, they can develop sufficient force to cause the vehicle to overturn.. Why is speed control on curves and turns especially important when driving any cargo tank vehicle? On curves and turns, the sideways movement of the liquid cargo to the outside of the turn ts added to the normal centrifugal force exerted on the vehicle which increases the possibility of the cargo tank vehicle overturning.
