1. Baffles in a tank are ________.
✓ Bulkheads with holes that let liquid flow through while slowing surge
Baffles are bulkheads with holes that allow the liquid to flow through but slow its front-to-back movement, reducing surge. They divide the tank's length but aren't solid. They make a tank handle more predictably than a smooth-bore one.
2. The most important driving rule for a tanker is to ________.
✓ Drive smoothly and avoid sudden steering, braking, or acceleration
Because of the high center of gravity and liquid surge, the key rule is to drive smoothly - gentle steering, early braking, and gradual acceleration - and avoid any sudden moves. Smoothness prevents both rollover and loss of control. It is the heart of safe tanker operation.
3. Liquid tankers are especially prone to rollover because they have:
✓ A high center of gravity
Much of a liquid tanker's weight sits high in the tank, giving it a high center of gravity that makes it tip and roll over easily, especially in curves. This is one of the biggest dangers of tank vehicles. Slow down for turns and steer gently to stay upright.
4. Tank vehicles have special inspection items that include ________.
✓ Leaks, manhole covers and gaskets, vents, valves, pipes, and hoses
Beyond the normal inspection, a tank vehicle requires checking for leaks; the condition of manhole covers and their gaskets; vapor vents; the intake, discharge, and cutoff valves; pipes and connections; hoses; and any special equipment. A defect in any of these can cause a leak or pressure problem. Inspect them all before driving.
5. Liquid surge is ________.
✓ The movement of liquid back and forth or side to side in a partly filled tank
Liquid surge is the wave-like movement of the liquid in a partially filled tank as the vehicle speeds up, slows down, or turns. This moving weight can strongly affect handling. Anticipating surge is a key tanker skill.
