What are spacing blocks, boards, or mats that separate cargo from its restraints called?

• A. Support beams
• B. Dunnage
• C. Straps
• D. Binders

Answer: (B)

The term that describes the spacing blocks, boards, or mats used to separate cargo from its restraints is known as dunnage. Dunnage is crucial in securing loads during transportation, preventing damage to the cargo by providing support and cushioning. By using dunnage, the space between the cargo and the restraints is effectively filled, ensuring that movement is minimized and that the cargo remains stable during transit.

Support beams are typically structural components used in the construction of warehouses or storage facilities, while straps and binders refer to the securing devices used to hold cargo in place. These elements can be important for securing loads, but they do not serve the function of separating cargo from restraints like dunnage does. Thus, the correct identification of dunnage underscores its essential role in cargo security and protection during transport.
