Which rescue tool power source is typically powered by pumps?

The correct choice is hydraulic because hydraulic rescue tools are designed to operate using fluid power, which is typically generated by pumps. These tools, commonly referred to as "Jaws of Life," utilize hydraulic fluid under pressure to create the force needed for tasks such as cutting and spreading metal in vehicle extrication situations. The hydraulic system allows for significant mechanical advantage, enabling firefighters to perform rescues where manual or electric tools may not provide enough power or efficiency.

Electric tools, while useful, rely on electrical power sources, often limiting their operational range due to the need for outlets or powered batteries. Pneumatic tools utilize compressed air as their power source, which, while effective in some situations, cannot match the force capabilities of hydraulic systems. Manual tools require physical effort by the user, which may not be feasible in emergencies where quick and powerful action is necessary. Thus, hydraulic tools, with their pump-driven operation, are the most effective in many emergency rescue scenarios.
