To prevent secondary fire by surely protecting facility equipment in a hydrogen station from fire heat against a fire in the vicinity of the hydrogen station.

In disaster prevention facilities of a hydrogen station 1 supplying hydrogen by storing liquefied hydrogen or compressed hydrogen, the disaster prevention facilities includes a hydrogen detection device 25 for detecting leakage of a hydrogen gas and a fire detection device 26 for detecting fire in the periphery, an injection head 18 arranged toward the facility equipment of the hydrogen station 1 and the circumference and injecting an injection liquid pressurized and supplied by a pump 11 from an injection liquid tank 9 via injection liquid piping 14, and control device 19 for protecting the facility equipment from fire heat by injecting the injection liquid from the injection head 18 by controlling an operation of the pump 11 when a hydrogen detection signal or a fire detection signal is entered.
