WHAT YOU WILL PRACTICE (FMCSA SECTION 8 — TANK VEHICLES) • Inspecting tank vehicles — leaks, welds, valves, pumps, hoses, manholes, vents, emergency shut-offs • High center of gravity — why tankers roll on curves and ramps, staying off the crown • Liquid surge — forward, back, and side-to-side movement of the load • Baffles and bulkheads — what cuts surge, what does not, and smooth-bore tanks • Outage and loading — expansion room, rated capacity, never filling a tank solid • Safe driving rules — extra stopping distance, skids, downhill, railroad crossings HOW TO STUDY 1.
