And move to the point of fire. When the fire reaches the fire point, the discharge of the fire-extinguishing water mixed with the foam liquid from the water discharge nozzle 3 toward the fire source is started. During this time, the driver can extinguish the fire while checking the outside state captured by the infrared camera 12 on the monitor 13. Further, in order to prevent oxygen deficiency in the vehicle 1, oxygen is appropriately supplied from the oxygen cylinder 14 into the vehicle 1. Furthermore, in order to protect the vehicle 1 from heat from a fire source, the self-cooling nozzle 9 is used to extinguish fire while spraying water toward the vehicle 1. If a person to be rescued is found at the site, the person is to be secured in a rescue space (not shown). At this time, although not shown, if a ladder or the like is provided, it is possible to rescue a person even when the vehicle 1 is located at a high place.
