Site management system for containing hazardous spills and leaks

An improved system for monitoring fuel storage and handling equipment which employs containment devices, leak detectors, storage tank level detectors, containment shrouds surrounding each mechanical device for extraction or addition of fuel from storage tanks is presented in which nonmechanical fluid sensors provide communications of the detection of fluid to a central processor which receives all sensor communications and provides a signal of the presence of fluid from the handling and storage equipment. The improvement incorporates various incidental emissions sensors placed proximate to containment devices. The incidental emissions sensors are indirectly actuated by the detection of spills and leaks and are in communication with the central processor. The system may also incorporate fail safe self diagnostic devices and differentiating sensors. In a preferred embodiment, Hall Effect sensors are used.
