The proposed technical solution relates to fire prevention equipment and can be used in industrial and civilian properties, including with an increased risk of fire, for locating hot spots, and also for efficiently extinguishing fires in facilities using automatic fire-extinguishing systems. The technical problem addressed by the claimed invention is to produce a fire-extinguishing device which does not have the drawbacks mentioned and has increased reliability, efficiency and manufacturability. The technical result of the claimed invention consists in elimination of the drawbacks of the prior art, in an increase in the reliability and manufacturability of a fire-extinguishing device and thus in an increase in the fire-extinguishing efficiency overall.
Pump operation panel simulator
A pump panel training device is provided and includes a plurality of simulated gages operable to imitate gages upon a fire truck pump panel, a plurality of simulated controls operable to imitate controls upon the fire truck pump panel, and a simulated water hose operable to imitate one of water temperature changes, water temperature pressure, and water hose vibration for the fire truck pump panel.
FIRE-FIGHTING FOAM CONCENTRATE
A method of fighting a fire, the method includes aerating a firefighting foam composition to form an areated firefighting foam; administering the aerated firefighting foam to a fire or applying the aerated firefighting foam to a surface of a volatile flammable liquid; wherein: the firefighting foam composition includes a sugar component comprising a monosaccharide sugar, a sugar alcohol, or a combination thereof; a polysaccharide thickener; a surfactant component comprising an anionic surfactant, a zwitterionic surfactant or a mixture of any two or more thereof; a water-miscible organic solvent; and at least about 30 wt. % water.
LOW NOISE DISCHARGE NOZZLE
A nozzle assembly for a fire suppression system includes a body having an inlet end for receiving a flow of fire extinguishing agent from the fire suppression system at an inlet pressure and a nozzle portion extending from the body. The nozzle portion includes an interior cavity having an outlet end, a center body arranged within the interior cavity adjacent the outlet end, and a plurality of exit orifices formed in an outer wall of the nozzle portion, in communication with the interior cavity, for vectoring the flow of fire extinguishing agent exiting therefrom and to reduce a noise level of the nozzle assembly. At least one perforated filter member is positioned upstream from the plurality of exit orifices formed in the nozzle portion, for reducing the inlet pressure of the flow of fire extinguishing agent.
Phosphorous-Nitrogen Alternative to PFC Foam
An alternative to aqueous film forming foams containing fluorine for firefighting foams for flammable liquid fires is a mist of aqueous ethyleneamine polyphosphate solution or fumed silica doped ethyleneamine polyphosphate solution. The method consists of spraying a mist of such solutions into a flammable liquid fire to suppress the flames and cool the fire. The mist approach also suppresses flames of wood fires. An alternate approach is to add ethyleneamine polyphosphate or fumed silica doped ethyleneamine polyphosphate to a fluorine free foam to form a flame retarded foam that is able to smother a flammable liquid fire.
STORAGE SYSTEMS AND METHODS
A storage system is disclosed where goods can be stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of rails (e.g., tracks) on which load handling devices can run. To take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked. The framework may be provided with one or more of the following exemplary services: power, power control, heating, lighting, cooling, sensors, and data logging devices. The provision of these services within the framework rather than across the system as a whole, can allow for flexibility in storage whilst reducing cost and inefficiency.
Hazard detection and containment
Multiple robotic monitors are located in a hydrocarbon storage or transport facility. Each robotic monitor is communicably coupled to other robotic monitors and includes a heat sensor configured to detect heat emitted by a hydrocarbon tank of the hydrocarbon storage or transport facility. A controller is communicably coupled to the heat sensor and configured to generate a heat signature based on the heat detected by the heat sensor. A pump is communicably coupled to the controller and configured to exert pressure on a fire retardant, responsive to the generation of the heat signature by the controller. An outlet is mechanically coupled to the pump and configured to discharge the fire retardant at the hydrocarbon tank.
CATIONIC SURFACTANT FOAM STABILIZING COMPOSITION
A foam stabilizing composition is disclosed. The composition comprises (A) a siloxane cationic surfactant comprising a cationic moiety having the formula Z.sup.1-D.sup.1-N(Y).sub.a(R).sub.2−a, wherein Z.sup.1 is a siloxane moiety, D.sup.1 is a divalent linking group, R is H or an unsubstituted hydrocarbyl group having from 1 to 4 carbon atoms, subscript a is 1 or 2, and each Y has formula -D-NR.sup.1.sub.3+, where D is a divalent linking group and each R.sup.1 is independently an unsubstituted hydrocarbyl group having from 1 to 4 carbon atoms. The composition also comprises (B) an organic cationic surfactant comprising a cationic moiety having the formula Z.sup.2-D.sup.2-N(Y).sub.b(R).sub.2−b, wherein Z.sup.2 is an unsubstituted hydrocarbyl group, D.sup.2 is a covalent bond or a divalent linking group, subscript b is 1 or 2, and R, Y, and subscript a, are defined above. An aqueous film-forming foam comprising the composition and method of using the same are also disclosed
SYSTEM AND METHOD FOR CALLING ATTENTION
A system for calling attention according to the present disclosure includes: at least one sensor configured to detect environmental information; a storage device in which condition data representing a condition under which a specific incident occurs is stored; determination means for determining a possibility of an occurrence of the specific incident based on a result of the detection by the sensor and the condition data stored in the storage device; and calling attention means for calling attention to a fact that there is the possibility of the occurrence of the specific incident, in which when the determination means determines that there is the possibility of the occurrence of the specific incident, the calling attention means calls attention to the fact that there is the possibility of the occurrence of the specific incident.
