What is one reason dry bulk tanks require special care?

• A. The load can shift
• B. The tank is always pressurized
• C. The cargo never changes weight
• D. The tanks are indestructible

Answer: (A)

Dry bulk tanks need special care because the cargo inside is free-flowing and can shift during transport. When the vehicle accelerates, brakes, or corners, the material’s inertia causes it to move, producing surge forces and changing the center of gravity. That can affect stability, steering, and braking, increase the risk of spills, and, in extreme cases, lead to a rollover if the load isn’t managed properly. This is why loading limits, proper unloading procedures, and sometimes baffling or compartmentalization are used to keep movement to a minimum. The other statements aren’t accurate: the tank isn’t always pressurized; cargo weight can change during loading, unloading, or due to moisture, and the tanks aren’t indestructible.
