What term describes solid wood or plastic blocks used to stabilize structures during extrication?

• A. A-post
• B. Chassis
• C. Cribbing
• D. Extension Rams

Answer: (C)

Cribbing is the technique of using solid blocks to create a stable, load-distributing footing during vehicle extrication. These blocks, made from wood or high-strength plastic, are stacked in an interlocking pattern to form a rigid support under contact points like frame rails or axles. The interlocking arrangement distributes the vehicle’s weight across a broad area, helping prevent movement or collapse as hydraulic tools or wedges are applied. Proper cribbing is dry, in good condition, and placed on solid ground with a base wide enough to resist tipping. The goal is a stable, adjustable base that maintains the vehicle’s position while rescuers work. The other terms refer to parts of the vehicle or to different tools, not to stabilization blocks used in this way.
