A total flood fire suppression system is provided for transportation tunnels and other human-occupied environments, which employs a selective gas delivery method for supplying a breathable fire-extinguishing agent to a location closest to a fire site. The agent is produced from ambient air at site and stored in high-pressure containers communicating with an addressed gas delivery hose installed throughout a tunnel.
