The invention also relates to a system (20) having a vehicle (2) of this type, as well as a corresponding method.

The invention pertains to an unmanned vehicle (2) for initiating a fire extinguishing action, wherein the vehicle comprises: a vehicle sensor unit (6) for detecting a fire parameter KF of a vehicle monitoring region (8), a vehicle communication unit (10) for receiving an instruction signal SI representing a detected fire, a target location (16) and/or a target region (137), and a navigation control unit (18) for navigating the vehicle (2) to the target location (16) based on the instruction signal SI, wherein the vehicle (2) is configured for detecting the fire parameter KF in the form of a verification fire parameter KV of the fire detector monitoring region (12) at the target location (16) by means of the vehicle sensor unit (6), wherein the vehicle (2) is configured for determining a verification fire status ZV by evaluating the verification fire parameter KV, and wherein the vehicle (2) is designed and/or configured for initiating a fire extinguishing action if the verification fire status ZV was determined. The invention also pertains to a system (20) with such a vehicle (2), as well as to a corresponding method.

A roadway conduit system includes a roadway conduit section that includes a floor portion with roadway surface configured to receive traveling vehicles, a ceiling portion, and at least one sidewall portion coupled to the floor portion and the ceiling portion such that the floor, ceiling, and at least one sidewall portions define a roadway conduit volume through which the traveling vehicles traverse the roadway conduit section. The roadway conduit section includes at least two fixedly connected preformed segments. The roadway conduit system also includes a roadway conduit ingress coupled to a first location of the roadway conduit section; a roadway conduit egress coupled to a second location of the roadway conduit section; and at least one air mover configured to circulate an airflow in the roadway conduit volume in a direction of at least one of the traveling vehicles.

1. Technical effect Increasing the quick action, efficiency and reliability of currently available explosion protection systems. 2. Essence of application The proposed explosion protection system contains an explosion detector and a shock wave damping agent discharge device. The detector consists of overpressure and flame sensors, an identification module and an electromagnetic signal wireless transmitter. The discharge device contains a container filled with damping agent. 3. Field of use Protection of infrastructural and industrial facilities from non-authorized and, terrorist explosions; localization of methane explosion energy in coal mines.

Disclosed is an assembly for discharging hydrated super absorbent polymer into a confined space for protection of a lineman or firefighter from a flash fire and fire suppression. A pressurized tank is filled with hydrated super absorbent polymer and connected to a conduit that is constructed and arranged to interchange various nozzles for personnel protection and fire suppression. The hydrated super absorbent polymer is discharged through a solenoid valve which can be operated by the individual operating within the space with a switch, an individual operating the control panel mounted in a utility truck or activated by a heat sensor in the confined space.

A transport facility includes a guide rail which is disposed along a travel path extending in a travel direction through an opening of a wall and which is configured to guide traveling of a transport vehicle, and a fire door configured to open and close the opening. The fire door is configured to, in closing the opening, move toward a first side in an arrangement direction from an open position to a closed position. The fire door includes a notch penetrating the fire door in the travel direction and open on the first side to prevent the fire door from coming into contact with the first rail body and the second rail body while the fire door is moving from the open position to the closed position.

Rock dust is applied to a mine wall for mine fire suppression in combination with a chemical foam, by generating the foam from air and a foamable liquid in a mixing chamber, and delivering the foam through one flexible conduit and air-entrained rock dust through another flexible conduit to a portable assembly composed of a Y-joint and a delivery nozzle for combining the foam and rock dust and applying the combination directly to a mine wall.
