Definitions
- the invention relates to methods and apparatus for controlling hazardous and/or flammable materials and the effects of such materials.
- Flammable and otherwise hazardous materials play an important role in the everyday lives of most people. Most people encounter flammable materials, such as gasoline, engine oil, and natural gas, and other hazardous materials, such as battery acid and concentrated detergents, without danger. Because the unsafe materials are contained, they typically present no problem for those that are nearby.
- the materials can injure or kill, such as when the container is damaged and the material escapes.
- hundreds of thousands of vehicular accidents occur each year on American highways.
- Many accident-related fire events occur when the region of the vehicle containing the fuel tank is impacted in an accident, spilling the fuel contents from the tank in the form of a spray, stream, and eventual pool around the vehicle.
- the highly ignitable spray mist generated upon impact may be exposed to ignition energy from sparks generated from vehicle deformation on impact for only a fraction of a second. This duration, however, may be long enough to ignite the fuel mist into a possible explosion, or more likely a fireball that ignites a developing pool of fuel surrounding the vehicle and create a more serious threat.
- a hazard control system comprises a housing configured to contain a control material and deliver the control material to neutralize a hazard in response to a trigger event.
- the control material is an extinguishant for retarding fire.
- the housing contains the extinguishant and includes at least one surface configured to rupture in response to a trigger event, such as an impact.
- the housing may also include a surface configured to substantially mate with a surface of a vehicle, such as a fuel tank surface.

- the housing 102 is suitably configured such that when the fuel pump 1510 is impacted sufficiently (such as in an accident) to break off or partially disconnect the fuel pump 1510 from the engine, facilitating the discharge of its flammable fluid contents and its subsequent ignition, the housing 102 should also break apart due to the same impact, releasing a cloud of suppressant around the region of fluid discharge to mitigate ignition and any resultant fires.
- the hazard control system 100 may be similarly adapted for other reservoirs and components, including superchargers and turbochargers, power steering pumps, vapor canisters, brake master cylinders, oil pumps, washer fluid reservoirs, fuel pressure reduction valves, and other valves attached to fluid vessels such as those on compressed natural gas (CNG) tanks, liquefied petroleum gas tanks (LPG), hydrogen tanks, and other alternate fueled vehicles.
- CNG compressed natural gas
- LPG liquefied petroleum gas tanks
- hydrogen tanks and other alternate fueled vehicles.
- the hazard control system 100 may also be adapted to fluid lines and connectors to control hazards in the event of the trigger event.
- the hazard control system 100 is configured for a connection point of a fluid line 1612 to a fluid reservoir 1614.
- the hazard confrol system 100 suitably includes a housing 102 in the form of a ring 1610 or similar shape that covers the attachment point of the fluid line 1612 and reservoir 1614 and attached to the surrounding face of the reservoir 1614.
- the ring 1610 has sufficient internal volume to contain enough control material 104 for a particular hazard, such as a dry chemical suppressant to prevent the ignition of any fluids released by the separation of line 1612 and reservoir 1614, for example due to an accident.
- the present embodiment also suitably includes a washer 1616 attached to the fluid line 1612.
- scored fracture lines 1618 may also be added to the outer faces of the ring 1610. If an event occurs that results in the pulling of the fluid line 1612 sufficiently as to separate it from the reservoir 1614 (such as due to a collision), then the washer 1616 (attached to the fluid line 1612) pulls through the ring 1610, rupturing the ring 1610 and dispersing the control material 104 around the surrounding area to suppress the hazard, such as ignition of fluid discharging from the disconnected line in the local area.
- the hazard control system 100 may be further configured for controlling hazards at the coupling of two fluid lines 1706.
- the housing 102 comprises two disks 1708A-B that are attached to each other, such as by use of an adhesive 1710.
- the outer surfaces of the disks form cavity 1712 to accommodate a coupling 1714 connecting together two fluid lines 1706.
- a flange 1716 may be attached to each fuel line 1706, outside of the coupling 1714 but captured within the disks 1708A-B when they are attached together.
- the outer faces of the disks 1708A-B may also have their surfaces scored radially from their fuel line openings to assist in panel breakup.
- the flange 1716 of either fluid line 1706 pulls through the panel disks 1708A-B and shatters them and the control material 104 is released at the same time to inhibit the relevant hazard, such as the ignition of any fluids discharged from the disconnecting lines.
- the adhesive force between the faces of the disks 1708A-B is designed to be stronger than the force required to fracture either disk 1708A-B by a flange 1716 on either line, to assure that disk fracturing occurs.
- the hazard control system 100 may be adapted for controlling a hazard in the event of damage to an oil pan.
- the hazard control system 100 includes a housing 102 over an oil pan 1810, suitably formed as a tightly fitting housing 102 which has been molded from liquid plastic or formed from double wall material, a rectangular formation of flat double- wall panels in the general shape of the oil pan 1810, or other suitable configuration.
- the housing 102 is attached to the oil pan 1810 by any appropriate mechanism and contains an appropriate confrol material 104.
- the housing 102 may extend over the lower engine block as well, in the event of engine failure in other areas.
- the housing 102 may also be placed as a sheet or curved panel some distance away from the oil pan 1810, but within proximity of the oil pan 1810 sufficient to assure its rupture from the discharged engine components. If the engine to which the oil pan 1810 is attached breaks a connecting rod 1812 and propels it through the oil pan 1810, discharging oil and fuel, the housing 102 also tends to break and discharge the control material 104, for example as a cloud of fire suppressant to prevent the ignition of the released oil and fuel near the exhaust manifold or other ignition sources.
- the hazard control system 100 may be configured for controlling hazards in an engine compartment.
- the hazard control system 100 is suitably configured to diminish a hazard in the event the engine compartment is damaged or another trigger event occurs.
- the hazard control system 100 may be configured to inhibit fire in the event the engine compartment of a convention automobile is damaged, such as in a front-end collision.
- an exemplary hazard control system 100 includes a housing 102 attached to or integrated into the hood of a car, truck, or other vehicle.
- the hood is configured to bend near their center point in the event of a front-end impact to dissipate energy and to prevent its disconnection at the hinges, which might possibly drive the hood toward the occupants.
- the vehicle hood 1914 is configured to deform as normally designed, forming a crease 1916 along a pre-set failure line.
- the housing 102 comprises a hood liner 1918 containing the control material 104, such as a fire extinguishing chemical, for example a dry chemical powder, and formed to the general shape of the underside of the hood 1914.
- the liner 1918 may have surface coverings to feature sound dampening, or have special sound dampening material added between the liner 1918 and the hood 1914.
- the liner 1918 When the hood 1914 deforms in a collision, the liner 1918 also deforms until it fractures.
- the liner 1918 may also include scored lines formed on the surface of the liner 1918 to assist in the breakup of the liner 1918.
- the control material 104 within the liner 1918 is discharged down onto the engine compartment to prevent any fires or other relevant hazard that might result from the discharge of flammable or otherwise hazardous materials.
- the hazard confrol system 100 is configured to respond to a thermal trigger event.
- the trigger event may comprise any appropriate thermal trigger event, such as a sudden rise in temperature or a temperature above a selected threshold.
- the thermal event may be generated by a fire 2010 underneath a fluid reservoir, such as a fuel tank 2012.
- the fuel tank 2012 has a housing 102 adjacent or integrated into the tank containing a control material 104.
- the housing 102 may be configured in any suitable manner, such as a series of flat panels containing control material 104 placed on the outer surfaces of the fuel tank 2012, a pre-formed and molded shape that conforms to the outer shape of the fuel tank 2012, or actually molded into the outer surface of the tank 2012 itself.
- the housing 102 when a pool fire 2014 occurs underneath the fuel tank 2012, the housing 102 cracks and breaks up, for example due to the resultant thermal loading, and discharges its contents of confrol material 104, for example to extinguish or mitigate the pool fire or otherwise confrol a hazard.
- the housing 102 is configured to crack and fracture upon exposure to thermal stresses above a selected threshold, such as from a pool fire 2014 a few inches from it.
- the housing 102 suitably includes a bottom face sheet facing the ground constrained by a rigid frame on its perimeter.
- the face sheet suitably has a higher thermal rate of expansion than the frame, such that when the housing 102 is exposed to heat above a selected threshold, the frame restrains the thermal expansion of the bottom face sheet, thus causing sfress within the panel to cause its cracking and rupture. Stress can be applied via pre-loading the panels in the frame or by other heat treatments such that minimal additional thermal stresses are required to achieve the fracture condition.
- the face sheet may melt, peel back, or otherwise move aside upon exposure to heat above a selected threshold.
- the confrol material 104 may be configured to swell upon exposure to heat above the selected threshold to cause or supplement the cracking and rupture of the face sheet.
- the face sheet to rupture may be pre-loaded by controlling of the forming and post-heating processes.
- Such techniques may be applied to plastic tanks that are molded and are in abundant use today, but which may be particularly vulnerable to failure when exposed to pool fires established underneath them.
- the hazard control system 100 may also be adapted for use in conjunction with nonflammable hazards, such as an enclosure that houses batteries that may be used on an electric vehicle. If such a container is ruptured, such as due to a collision, and the enclosure is ruptured as well as the batteries, caustic and corrosive battery acids can be released to the environment. Such acids pose a hazard to the vehicle occupants, the environment, rescue personnel, and those hired to inspect the wreckage and transport it to a safe area.
- nonflammable hazards such as an enclosure that houses batteries that may be used on an electric vehicle. If such a container is ruptured, such as due to a collision, and the enclosure is ruptured as well as the batteries, caustic and corrosive battery acids can be released to the environment. Such acids pose a hazard to the vehicle occupants, the environment, rescue personnel, and those hired to inspect the wreckage and transport it to a safe area.
- a hazard control system 100 may be configured for any application where a caustic, corrosive, toxic, or otherwise harmful chemical may be unintentionally released, such as due to a vehicle collision or accident, including tractor-trailers and other transport vehicles that haul such caustic and dangerous chemicals in large quantities.
- the hazard control system 100 may employ a housing 102 covering or adjacent to the single battery used on virtually all vehicles to inhibit excessive damage resulting from a potential leakage or spray of battery acid within the engine compartment, or toward operators if the battery is damaged in a collision or explodes due to other damage to the battery.
- the housing 102 comprises one or more protective panels 2110 adjacent a battery enclosure 2112, such as on the exterior and/or in the interior of the battery enclosure 2112. If the enclosure 2112 is damaged, such as in a collision, the battery enclosure 2112 may rupture 2114 and permit the spillage of acid 2120 from the damaged batteries 2116.
- the protective panels 2110 are also configured to rupture in the event of damage to the enclosure 2112, which facilitates discharge of the control material 104, such as a neutralizing chemical 2118, to confrol or mitigate the hazard presented by the released acid.
- the neutralizing chemical may be any appropriate material, such as sodium bicarbonate.
- the various components of the hazard control system 100 may be formed according to any appropriate technique or method.
- the housing 102 and the core 112 may be cut, cast, extruded, machined, stamped, molded, or otherwise formed to configure to the desired shapes.
- the housing 102 is suitably vacuum molded, injection molded, or blow molded to form a desired configuration, such as to conform the housing 102 to a particular shape like the exterior of a particular vehicle fuel tank.
- the face sheets 106 may be molded so that one exterior surface conforms to the external surface of the fuel tank and the second exterior surface fits within the fuel tank compartment.
- the face sheets 106 are suitably vacuum molded.
- the housing 102 is suitably blow molded.
- a core 112 may be formed, for example by extrusion.
- the compartments, channels 610, or other interior structure of the housing 102 may be generated by forming the interior surface of one or more face sheets 106, for example during the molding of the face sheets 106.
- the face sheets 106 may then be joined to form the housing 102, suitably surrounding the core 112, if desired. If the ends are sealed using end caps, the end caps may be attached, for example after insertion of the control material 104.
- the housing 102 is suitably formed of a plastic or other material that may exhibit a grain, or a tendency to more easily crack or shatter in a particular direction.
- the interior structure of the housing 102 such as the core 112, the channel partitions, rows of compartments, or the like, may be configured to extend perpendicularly to the grain. Because the interior structure may tend to support the integrity of the housing 102, extending the interior structure perpendicular to the grain of the housing 102 material may facilitate easier and/or more extensive shattering of the housing 102. Orienting the grain perpendicular to the channels promotes opening of multiple channels or compartments to discharge more control material, as the cracks tend to propagate along the grain across multiple channels or compartments.
- the confrol material 104 may be added in any suitable manner, such as before joining the housing 102 components or after assembly of the housing 102.
- the confrol material 104 may be added by standing the housing 102 upright and resting on one end and pouring the control material 104 into the upper end of the housing 102.
- the confrol material 104 may be added to the individual compartments or channels 610 in any other appropriate manner, such as by inserting the control material 104 directly into each channel or compartment, for example if the compartments or channels 610 are not interconnected.
- the confrol material 104 can be poured, injected under pressure, or otherwise inserted into the channels 610.
- the access openings for adding the control material 104 are then suitably closed. If the housing 102 uses end caps, the end cap 810 can be snapped into position, substantially sealing the housing 102. Any ' other relevant system for maintaining the control material 104 within the housing 102 may be implemented, such as sealing the openings with caulk, putty, plugs, membranes, tape, or other mechanism.
- the hazard control system 100 may then be attached to the relevant hazard source.
- the particular implementations shown and described are illustrative of the invention and its best mode and are not intended to otherwise limit the scope of the present invention in any way. Indeed, for the sake of brevity, conventional manufacturing, connection, preparation, and other functional aspects of the system may not be described in detail.
- the connecting lines shown in the various figures are intended to represent exemplary functional relationships and/or physical couplings between the various elements. Many alternative or additional functional relationships or physical connections may be present in a practical system.
