What is the primary purpose of cribbing in stabilization operations?

• A. To decorate the scene.
• B. To speed up the crew's movement.
• C. To distribute load and provide stable support.
• D. To increase the color variety of wood.

Answer: (C)

Cribbing is used to distribute the load and create a stable support base for stabilization operations. By stacking interlocking blocks to form a solid platform, the weight of the supported object is carried by multiple contact points, spreading the load and reducing pressure at any single point. This prevents sinking into soft ground or shifting under load and provides a rigid base that stays stable as jacks or wedges are applied, enabling safe lifting and stabilization. It also allows adjustment to uneven surfaces by adding or removing blocks to achieve level contact. It is not for decoration, speeding crew movement, or changing the color of the wood.
