An entity catastrophic security system is provided to prevent criminal, human error or major entity failures from causing major catastrophic results. The system employs entity danger signal personnel and devices to generate danger signals, a complex code scheme to assure security of signals, entity processing devices to sense the danger signals, to place the entity into a controlled, restricted state, to signal external processing devices and authorized personnel of the dangerous entity conditions, and to inform national and local authorities of the entity's condition. Even without danger signals from the entity, the external authorized personnel may deem to take over control of the entity. In either case, by way of an entity control device, the entity catastrophic security system also remotely, controllably operates the entity from the external processing device, so as to enforce safe disposition of the entity.
