Stabilization System

What Is Stabilization System?

A stabilization system refers to specialized extrication hardware — including tensioned buttress struts, step chocks, hydraulic shore jacks, and wood cribbing — deployed to immobilize unstable vehicles or collapsed structures before rescue entry.

Why Stabilization System Matters on the Fireground

Attempting to cut or spread a vehicle resting on its side without stabilization causes sudden vehicle shifts that crush rescuers or worsen patient spinal injuries. Proper buttress strut stabilization creates a rigid tripod base.

Relevant NFPA Standards

• NFPA 1960: Standard for Fire Hose Connections, Spray Nozzles, Manufacturer's Design of Fire Department Ground Ladders, Fire Hose, and Powered Rescue Tools
• NFPA 2500: Standard on Organizational Capabilities for Technical Search and Rescue and Life Safety Rope and Equipment for Emergency Services

Field Procedures & Tactical Steps

1. Place wheel chocks and step chocks under vehicle frame members to capture initial suspension movement.
2. Set up tensioned buttress struts at 45 to 60 degree angles against vehicle sides.
3. Attach ratchet straps from strut bases to vehicle frame anchor points.
4. Tighten ratchet straps to lock vehicle firmly against ground and struts.
5. Re-check strut tension continuously as metal is cut or moved during extrication.

Common Context & Application

Deployed on vehicle rollover crashes, vehicles on their side/roof, building collapse scenes, and trench rescues.
