A vehicle-mounted fire control system for safe transport and management of a flammable liquid transported by a vehicle. The system includes a liquid storage vessel having an outer protective wall, a buffer space, and an interior wall. The outer protective wall encloses the buffer space and the interior wall. A rollover sensor measures a roll angle of the liquid storage vessel. An impact sensor measures impact acceleration of the liquid storage vessel. A smoke detector is located inside the buffer space. A fire extinguisher having a plurality of nozzles sprays fire suppressant at least onto one of the outer wall or the interior wall upon command. Electrically actuated solenoids, each one in communication with the nozzles, are configured to automatically open and spray fire suppressant upon the command. A processor programmed to issue the command upon detection of a hazard.
