Multiple robotic monitors are located in a hydrocarbon storage or transport facility. Each robotic monitor is communicably coupled to other robotic monitors and includes a heat sensor configured to detect heat emitted by a hydrocarbon tank of the hydrocarbon storage or transport facility. A controller is communicably coupled to the heat sensor and configured to generate a heat signature based on the heat detected by the heat sensor. A pump is communicably coupled to the controller and configured to exert pressure on a fire retardant, responsive to the generation of the heat signature by the controller. An outlet is mechanically coupled to the pump and configured to discharge the fire retardant at the hydrocarbon tank.
