IT consists of four main components — cutters, spreaders, rams, and the power source. Before the tool was invented, first responders generally used saws to cut open car frames after they crashed. These were known to create sparks on occasion, which increased the risk of fires and even explosions.
What is the specification of jaws of Life?

What are the different types of jaws of Life?
There are specifically four jaws of life. They are; spreaders, rams, cutters, and combination tools. These hydraulic rescue tools play different roles to achieve one purpose – to rescue stuck accident victims from badly crushed vehicles.
What will make the jaws of life work?
The Jaws of Life tool uses a piston system, similar to a car engine. A gasoline or electrical power source pushes hydraulic fluid into the first piston, which then pushes down the second piston and applies immense pressure into the tool quickly.
What do firefighters call the Jaws of Life?
Cutters. The cutter is a pair of hydraulically powered shears that is designed to cut through metal. It is often called the jaws of life, owing to the shape and configuration of its blades.
What fluid does the jaws of Life use and why?
Oil can be used in many types of hydraulic equipment, but because oil is extremely flammable, the Jaws of Life typically use phosphate ester fluid, which is both non-flammable and does not conduct electricity.

An early prototype of the HURST Power Tool (aka Jaws of Life) is demonstrated at HURST Headquarters in Warrington, Pennsylvania. George HURST is pictured on the left.
How does a hydraulic work?
Hydraulic fluid creates fluid power by pumping the fluid through the hydraulic system. The fluid flows to the cylinder through the valve, and the hydraulic energy converts it back to mechanical energy. The valves aid to direct the flow of the fluid and the pressure can be relieved if needed.
