A readily portable hydraulic power source for supplying hydraulic fluid pressure to emergency hydraulic tools is foot-operated such that the operator's hands are left free to use the hydraulic tools and both the tools and power source may be operated by a single person. The power source includes a generally planar base member, a hydraulic pump fixedly mounted at one end of the base member, a foot-engaging planar member in generally overlying relation to the base member, a hinge connecting ends of the base member and the planar member for movement of the planar member relative to the base, and a resilient spring between the base and planar members to urge the members pivotally apart upon release of pressure from the operator's foot. The operator's foot is retained by straps and a heel retaining portion attached to the planar member, with the heel portion having an arm operatively connected to a hydraulic piston of the pump. Fluid conduits are provided from the hydraulic pump for connection to an emergency tool and from a hydraulic fluid reservoir, which is strapable about the operator's torso, to supply fluid to the hydraulic pump.
