The fire hose pack roller includes a first embodiment where the device is held in place by a bracket positioned under a vehicle's tire and the weight of the vehicle secures the device for use or in a second embodiment where the device is removably mounted to the vehicle. The hose pack roller device includes a pair of collapsible arms that are unfolded and the fire hose is would around pegs mounted on the arms. The device further includes a set of rollers that squeezes air and water from the hose as it is wound. Once wound the hose is easily folded into a Gansner type pack for storage of the hose. The arms of the device may be folded closed such that the device forms a compact unit for storage. No external power supply is required.

Systems and methods are provided for aircraft fire extinguishing with heated tubing. One example is a fire extinguishing system that includes a container configured to store a fire extinguishing agent, a tube configured to transport the fire extinguishing agent from the container to a compartment of the aircraft, and a valve configured to initiate a discharge of the fire extinguishing agent from the container and through the tube. The fire extinguishing system also includes a heating element thermally coupled with the tube, and a control member in a cockpit of the aircraft configured to direct the heating element to heat the tube prior to initiating the discharge of the fire extinguishing agent via the valve.

A firefighter training unit for simulating use of a fire extinguishing system, the unit including: a reel; a user-manipulable nozzle; a hose having opposite ends attached respectively to the reel and the nozzle and being partially wound around the reel, wherein rotation of the reel in a first rotational direction allows the hose to be unwound from the reel; a motor configured to drive the reel in a second rotational direction which causes the hose to be wound onto the reel; one or more devices for providing one or more output signals corresponding to one or more simulated operating conditions of the fire extinguishing system; and a controller configured to drive the motor in response to the one or more output signals so as to apply torque to the reel in the second rotational direction to simulate forces applied to the hose during operation of the fire extinguishing system.

A hand tool for straightening a fluid line has two sections that are configured to interlock and define an elongated line straightening channel between ends of the tool. One tool section has recesses and the other tool section has projections. The hand tool is assembled by moving the two sections together and interlocking the projections and recesses to form a tubular configuration or tunnel that straightens the line.

Disclosed is a method for extinguishing a fire, comprising the following steps: a dimensionally stable hose and a reel comprising a central water connection that is rotatable relative to the reel are provided, the hose being wound on the reel; the dimensionally stable hose is designed in such a way as to have a second connection; furthermore, a transport device is provided in which the reel is rotatably mounted in order for the hose to be unwound; the hose is connected to the water supply conduit; the hose is unwound from the reel only by the length required to reach and extinguish the fire. The disclosed method dispenses with the time-consuming installing of hoses in bays and eliminates the associated risk of tripping over the hose. In the disclosed method, the wound dimensionally stable hose forms the hose supply. Moreover, the system can be filled with water and pressurized without any preparation at any time. The hose supply can remain in the bag. Also disclosed is a corresponding device, which can additionally be used as a rescue device.

A coupling includes an engagement face included in an engagement hook which is set at an angle in a range where the engagement face is still inclined at a positive angle, which is maintained when the coupling and a counterpart coupling are in a coupling state, even if a fluid leaks as a result of opening a sealing portion of the couplings, at a state where the coupling state is maintained, or even if a hose or the like fitted to the coupling bursts when high pressure is applied to the coupling, the hose, etc., while in use.
