Hydraulic Rescue Tools

What Is Hydraulic Rescue Tools?

Hydraulic rescue tools (commonly known as the Hurst 'Jaws of Life') are specialized extrication instruments — classified as spreaders, cutters, rams, and combo tools — powered by gas, electric, or battery-operated hydraulic pumps generating 10,000+ PSI.

Why Hydraulic Rescue Tools Matters on the Fireground

Vehicle extrication requires precise application of immense force. Spreaders push crushed metal apart, cutters sever roof posts, and rams push collapsed dashboards off trapped limbs, transforming an impossible rescue into a controlled 10-minute extraction.

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 1930: Standard on Fire and Emergency Service Use of Thermal Imagers, Two-Way Portable RF Voice Communication Devices, Ground Ladders, Rescue Tools, Fire Hose, and Fire Hose Appliances

Field Procedures & Tactical Steps

1. Connect hydraulic lines from power unit to tool (or verify battery charge on eDRAULIC battery-powered tools).
2. Select the proper tool for the task: spreader for door opening/popping, cutter for post severing, ram for dash displacement.
3. Position tool tips at a 90-degree angle to the target surface to prevent tool slippage under load.
4. Operate deadman control valve smoothly, watching metal reaction and monitoring patient protection shields.
5. Retract tool arms completely before returning unit to apparatus mounting brackets.

Common Context & Application

Carried on rescue trucks, squad units, and ladder apparatus for vehicle extrication, USAR, and heavy machinery rescue.
