Abstract:
1. Fire prevention equipment comprising: fire-extinguishing agent supplying equipment for pressurizing and supplying a water-based fire-extinguishing agent via a pipe; an electrification spray head for electrifying jetted particles of the fire-extinguishing agent pressurized and supplied by the fire-extinguishing agent supplying equipment and spraying the particles, the head being installed in a protection section; and a voltage application unit for applying an electrification voltage to the electrification spray head, wherein the electrification spray head is provided with and wherein the voltage application unit charges the jetted particles by applying an external electric field generated by applying a voltage between the induction electrode unit and the water-side electrode unit of the electrification spray head to the water-based fire-extinguishing agent in a jetting process from the injection nozzle.
