Description
BATTERY SPILL CONTAINMENT SYSTEM AND METHOD OF MAKING THE
SAME
FIELD
The present disclosure relates generally to spill containment systems and methods for containing a hazardous substance spilled from at least one device and, more particularly, to battery spill containment assemblies and methods for containing spills from battery storage racks.
BACKGROUND
In our industrial society, devices often contain substances that may leak or spill undesirably onto other devices, persons, or the environment. For example, batteries may be stored on battery racks, cabinets, relay racks, a combination of one or more of these structures, or any other suitable structure. These batteries may serve as a backup power supply for data communication centers, telecommunication equipment, utility substations, broadband equipment, cable equipment, and/or computers. These batteries may contain acidic or alkaline substances that may leak or spill onto other batteries, cables, equipment, and other devices as well as personnel, thereby posing a hazard to people and property. Sulfuric acid, commonly found in batteries, is an extremely hazardous material regulated by federal, state and local governments. With respect to the storage of batteries, Article 64 of the Uniform Fire Code requires a four-inch high containment barrier with an acid neutralization capability to a pH of 7-9. Additionally, state and city requirements are often more stringent than National Fire Protection Association ("NFPA") guidelines. In many cases, Valve Regulated Lead Acid (VRLA) batteries, as well as other batteries and devices other than batteries, are required by Date Recue/Date Received 2020-08-13 city or county ordinances to have spill containment devices or other control devices.
Additionally, in many cases, insurance carriers require spill containment or control devices to be used when storing batteries or other devices that contain hazardous materials. Other devices that may use spill containment systems include, but are not limited to, air conditioning .. units that may drip water from condensation or leak Freon, and water heaters that may leak water.
Accordingly, it is desirable to contain leaks and spills from hazardous devices such as batteries. While spill containment systems exist, the existing systems need to be improved and are cost prohibitive in many cases. Conventional spill containment systems are attached to the .. floor by a larger number of fasteners that penetrate concrete, wood, or tile flooring.
Accordingly, installing conventional spill containment systems is very costly, labor intensive, and involves defacing or damaging the floor or substrate. Additionally, many floors in older facilities have asbestos tile and therefore drilling into the floor poses a health hazard due to the release asbestos fibers into the air. Additionally, storage space for battery backup systems is .. limited and precious. As companies become increasingly dependent on computers, their need for storing a greater number of batteries increases. Real estate, battery cabinets, and relay rack space are at a premium. Thus, companies utilizing battery backup systems would like to be able to store as many batteries as they can in their space, such as a warehouse or basement or other rooms. Some of the rooms may have structures that obstruct the floor space (such as .. columns); others may have non-rectangular areas. Battery spill containment systems should be able to be installed in virtually any of these diverse rooms. The systems should also be able to be installed quickly and easily in a given space at a low cost, and with minimal effort and time. Additionally, rails of the spill containment systems should provide a reinforced and secure environment around the perimeter of the batteries, but yet have the ability to be removed to allow for maintenance or battery change out as the batteries reach the end of their lives.
Accordingly, it is desirable to have improved designs of a battery spill containment system that permits a greater number of batteries to be stored in a given space (e.g., on relay racks or in cabinets) with easy access to the batteries, increased safety, and modularity of .. designs that incorporate spill containment.

DETAILED DESCRIPTION
The present disclosure relates to spill containment assemblies and methods of installing the spill containment assemblies onto both new and existing support structures. The
-5-, spill containment assemblies of the present disclosure are configured to contain leaks and spills from a variety of devices, such as batteries which may leak hazardous materials (e.g., sulfuric acid), air conditioning units which may leak Freon, and hot water heaters which may leak water. Additionally, the spill containment assemblies of the present disclosure are configured to be coupled to the structure which supports the devices, rather than a floor or substrate on which the spill containment assembly rests, thereby reducing installation time, eliminating the risk of drilling into older floors, which typically contain asbestos, and minimizing damage to the floor. Moreover, the spill containment assemblies of the present disclosure are configured to retrofit existing support structures, such as existing battery racks (e.g., the spill containment assemblies are configured to be installed on an existing support structure in situ). The spill containment assemblies of the present disclosure are also configured to be installed during the installation of a new support structure.
Furthermore, the spill containment assemblies of the present disclosure are configured to be readily detached from the support structure (e.g., battery rack), such as to facilitate maintenance or replacement of the devices (e.g., batteries) supported on the support structure.
With reference now to FIGs. 1 and 2A, a spill containment assembly 100 according to one embodiment of the present disclosure is illustrated attached to, and installed below, a battery storage rack 101. In FIG. 1, the spill containment assembly 100 is illustrated installed below a non-seismic battery storage rack 101. In FIG. 2, the spill containment assembly 100 is illustrated installed below a seismic-rated battery storage rack 101 configured to meet or exceed seismic shake testing per International Building Code ("IBC") 2009, IBC
2012, and Institute of Electrical and Electronics Engineers ("IEEE") 693. It will be appreciated, however, that the spill containment assembles 100 of the present disclosure may be installed below any other suitable structure in order to contain leaks and spills, such as, for instance air conditioning units or hot water heaters. In the illustrated embodiment, the battery storage racks 101 include a plurality of front and rear support stanchions 102, 103, respectively. Although the front and rear support stanchions 102, 103 in the illustrated embodiment are vertical, in one or more alternate embodiments, the front and rear support stanchions 102, 103 may have any other suitable orientation and configuration. The battery storage racks 101 also include a plurality of horizontal support braces 104 extending between and interconnecting

Moreover, the straight wall segments 109a, 109b, the corner wall segments 110, the clips 111, and the base plate 112 together define a spill containment chamber or cavity 113 disposed below the battery storage rack 101 and configured to contain any spills or leaks from the batteries 115 stored on the battery storage rack 101.
In the illustrated embodiment, the spill containment assembly 100 includes two straight wall segments 109a along each of the longer sides of the spill containment assembly 100, one straight wall segment 109b along each of the shorter sides of the spill containment assembly 100, and four comer wall segments 110. It will be appreciated, however, that the spill containment assembly 100 may have any other suitable shape and configuration, such as, for example, circular or square, depending upon the configuration of the structure under which the spill containment assembly 100 is installed (e.g., a battery storage rack, an air conditioning unit, or a hot water heater). Additionally, the spill containment assembly 100 may have any other suitable number of straight wall segments 109a, 109b and comer wall segments 110. For
-7-instance, in one embodiment, the longer sides and the shorter sides of the spill containment assembly 100 may each include only one straight wall segment 109a, 109b.
With reference now to the embodiment illustrated in FIG. 2B, the straight wall segments 109a, 109b each include a vertical flange 120 having an upper end 121 and a lower end 122 opposite the upper end 121 and a horizontal flange 123 projecting inward from the lower end 122 of the vertical flange 120. The horizontal flange 123 includes an outer end 124 interconnected to the lower end 122 of the vertical flange 120 and an inner end 125 opposite the outer end 124.

In the illustrated embodiment, the first and second vertical flanges 126, 127 of the corner wall segments 110 define an angle a of approximately 90 degrees, although it will be appreciated that the first and second vertical flanges 126, 127 may define any other suitable angle depending upon the configuration of the spill containment assembly 100. In an alternate embodiment, the straight wall segments 109a, 109b and the corner wall segments 110 may be provided without the horizontal flanges 123, 132, 133.
Additionally, although the straight wall segments 109a, 109b and the corner wall segments 110 have been described above as having vertical flanges 120 and 126, 127, respectively, in one or more alternate embodiments, the flanges 120, 126, 127 may be non-vertical (e.g., the flanges 120, 126, 127 may be canted at any suitable angle, such as, for instance, approximately five degrees to approximately forty-five degrees relative to an imaginary vertical plane).
Moreover, in one or more alternate embodiments, the vertical flanges 120, 126, 127 of the wall segments 109a, 109b, 110 may be non-planar (e.g., curved).
With reference now to the embodiment illustrated in FIG. 2B, the straight wall segments 109a, 109b each include a vertical flange 120 having an upper end 121 and a lower end 122 opposite the upper end 121 and a horizontal flange 123 projecting inward from the lower end 122 of the vertical flange 120. The horizontal flange 123 includes an outer end 124 interconnected to the lower end 122 of the vertical flange 120 and an inner end 125 opposite the outer end 124.

In the embodiment illustrated in FIG. 2C, the corner wall segments 110 each include first and second vertical flanges 126, 127 having upper ends 128, 129, respectively, and lower ends 130, 131, respectively. The corner wall segments 110 each also include first and second horizontal flanges 132, 133 projecting inward from the lower ends 130, 131 of the first and second vertical flanges 126, 127, respectively. The first and second horizontal flanges 132, 133 include outer ends 134, 135 interconnected to the lower ends 130, 131 of the first and second vertical flanges 126, 127, respectively, and inner ends 136, 137 opposite the respective outer ends 134, 135. In the illustrated embodiment, the first and second vertical flanges 126, 127 of the corner wall segments 110 define an angle a of approximately 90 degrees, although it will be appreciated that the first and second vertical flanges 126, 127 may define any other suitable angle depending upon the configuration of the spill containment assembly 100. In an alternate embodiment, the straight wall segments 109a, 109b and the corner wall segments 110 may be provided without the horizontal flanges 123, 132, 133.
Additionally, although the straight wall segments 109a, 109b and the corner wall segments 110 have been described above as having vertical flanges 120 and 126, 127, respectively, in one or more alternate embodiments, the flanges 120, 126, 127 may be non-vertical (e.g., the flanges 120, 126, 127 may be canted at any suitable angle, such as, for instance, approximately five degrees to approximately forty-five degrees relative to an imaginary vertical plane).
Moreover, in one or more alternate embodiments, the vertical flanges 120, 126, 127 of the wall segments 109a, 109b, 110 may be non-planar (e.g., curved).
-8-With reference again to the embodiment illustrated in FIGs. 1 and 2A, the straight wall segments 109b on the shorter sides of the spill containment assembly 100 overlap a portion of the corner wall segments 110 (i.e., lap joints 138 are defined between the straight wall segments 109b on each of the shorter sides of the spill containment assembly 100 and the corner wall segments 110). Accordingly, two lap joints 138 are defined along each of the shorter sides of the spill containment assembly 100. The overlapping portions of the straight wall segments 109b and the corner wall segments 110 may be coupled together by any suitable means, such as, for example, mechanical fastening, welding, bonding, or adhering.
The two straight wall segments 109a on each of the longer sides of the spill containment assembly 100 abut each other and abut the corner wall segments 110 (i.e., butt joints 139 are defined between the two straight wall segments 109a on each of the longer sides of the spill containment assembly 100 and between the straight wall segments 109a and the corner wall segments 110). Accordingly, three butt joints 139 are defined along each of the longer sides of the spill containment assembly 100.
As described in detail below, the plurality of clips 111 are configured to overlap the butt joints 139, thereby coupling together the two straight wall segments 109a along each of the two longer sides of the spill containment assembly 100 and coupling the two straight wall segments 109a to the corner wall segments 110. Additionally, in one embodiment, the clips 111 may be configured to maintain a fluid-tight seal around the butt joints 139 (i.e., the clips 111 may be configured to join the straight wall segments 109a and the corner wall segments 110 together to ensure a fluid-tight fit). It will be appreciated, however, that the clips 111 do not need to maintain a fluid-tight seal around the butt joints 139 as the spill containment assembly 100 includes a liner 114, described in detail below, which is configured to prevent spilled or leaked fluid (e.g., sulfuric acid from batteries) from escaping the spill containment chamber 113 and thereby contaminating surrounding areas. In an alternate embodiment, the straight wall segments 109b on the shorter sides of the spill containment assembly 100 may abut, rather than underlap, the corner wall segments 110 (i.e., butt joints may be defined along the shorter sides of the spill containment assembly 100, similar to the butt joints 139 defined along each of the longer sides of the spill containment assembly 100) and clips 111 may be
The two straight wall segments 109a on each of the longer sides of the spill containment assembly 100 abut each other and abut the corner wall segments 110 (i.e., butt joints 139 are defined between the two straight wall segments 109a on each of the longer sides of the spill containment assembly 100 and between the straight wall segments 109a and the corner wall segments 110). Accordingly, three butt joints 139 are defined along each of the longer sides of the spill containment assembly 100.

In an alternate embodiment, the straight wall segments 109b on the shorter sides of the spill containment assembly 100 may abut, rather than underlap, the corner wall segments 110 (i.e., butt joints may be defined along the shorter sides of the spill containment assembly 100, similar to the butt joints 139 defined along each of the longer sides of the spill containment assembly 100) and clips 111 may be
-9-provided to couple the straight wall segments 109b on the shorter sides of the spill containment assembly 100 to the corner wall segments 110.
With reference now to the embodiment illustrated in FIG. 3, the adjustable clip 111 will now be described in more detail.

In one embodiment, the upper flange 143 may be generally horizontal. The upper flange 143 includes an inner end 144 interconnected to the upper end 142 of the inner vertical flange 140 and an outer end 145 opposite the inner end 144. In the illustrated embodiment, the upper flange 143 is arcuate, although it will be appreciated that the upper flange 143 may be straight (e.g., planar) and still fall within the scope and spirit of the .. present disclosure. Each adjustable clip 111 also includes an outer vertical flange 146 extending downward from the outer end 145 of the upper flange 143. The outer vertical flange 146 includes an upper end 147 interconnected to the outer end 145 of the upper flange 143 and a lower end 148 opposite the upper end 147. Although the outer flange 146 is depicted as a vertical and planar, in one or more alternate embodiments, the flange 146 may not be vertical (e.g., the flange 146 may be canted) and/or the flange 146 may not be planar (e.g., the flange 146 may be curved). In one embodiment, the shape of the outer flange 146 matches or substantially matches the shape of the first vertical flange 126 of the corner wall segment 110 and/or the shape of the vertical flanges 120 of the straight wall segments 109a. Each adjustable clip 111 further includes a lower horizontal flange 149 extending inward from the lower end 148 of the outer vertical flange 146. In one embodiment, the lower horizontal flange 149 may rest on the ground or other substrate on which the storage rack 101 is supported. The lower horizontal flange 149 includes an outer end 150 interconnected to the lower end 148 of the outer vertical flange 146 and an inner end 151 opposite the outer end 150.
Each adjustable clip 111 also includes a lip 152 extending upward from the inner end 151 of the lower horizontal flange 149. In the illustrated embodiment, the inner vertical flange 140, the upper
With reference now to the embodiment illustrated in FIG. 3, the adjustable clip 111 will now be described in more detail. One of the corner wall segments 110 is omitted in FIG. 3 to reveal one of the adjustable clips 111. As illustrated in FIG. 3, each adjustable clip 111 includes an adjustable inner vertical flange 140 having a lower end 141 and an upper end 142 opposite the lower end 141. Each adjustable clip 111 also includes an upper flange 143 projecting outward from the upper end 142 of the inner vertical flange 140, although in one or more alternate embodiments, the flange 143 may project outward from the lower end of the inner vertical flange 140. In one embodiment, the upper flange 143 may be generally horizontal. The upper flange 143 includes an inner end 144 interconnected to the upper end 142 of the inner vertical flange 140 and an outer end 145 opposite the inner end 144. In the illustrated embodiment, the upper flange 143 is arcuate, although it will be appreciated that the upper flange 143 may be straight (e.g., planar) and still fall within the scope and spirit of the .. present disclosure. Each adjustable clip 111 also includes an outer vertical flange 146 extending downward from the outer end 145 of the upper flange 143. The outer vertical flange 146 includes an upper end 147 interconnected to the outer end 145 of the upper flange 143 and a lower end 148 opposite the upper end 147. Although the outer flange 146 is depicted as a vertical and planar, in one or more alternate embodiments, the flange 146 may not be vertical (e.g., the flange 146 may be canted) and/or the flange 146 may not be planar (e.g., the flange 146 may be curved). In one embodiment, the shape of the outer flange 146 matches or substantially matches the shape of the first vertical flange 126 of the corner wall segment 110 and/or the shape of the vertical flanges 120 of the straight wall segments 109a. Each adjustable clip 111 further includes a lower horizontal flange 149 extending inward from the lower end 148 of the outer vertical flange 146. In one embodiment, the lower horizontal flange 149 may rest on the ground or other substrate on which the storage rack 101 is supported. The lower horizontal flange 149 includes an outer end 150 interconnected to the lower end 148 of the outer vertical flange 146 and an inner end 151 opposite the outer end 150.
Each adjustable clip 111 also includes a lip 152 extending upward from the inner end 151 of the lower horizontal flange 149. In the illustrated embodiment, the inner vertical flange 140, the upper
-10-, flange 143, the outer vertical flange 146, the lower horizontal flange 149, and the lip 152 are integrally formed (e.g., by roll forming sheet metal), although in one or more alternate embodiments, the inner vertical flange 140, the upper flange 143, the outer vertical flange 146, the lower horizontal flange 149, and the lip 152 may be separately formed and coupled together by any suitable process, such as, for instance, welding.
With continued reference to the embodiment illustrated in FIG. 3, each adjustable clip 111 also includes an aperture 153 configured to receive a fastener 154 coupling the clip 111 to one of the plurality of stanchions 102, 103 on the battery support rack 101.
In the illustrated embodiment, the aperture 153 is a notch or slot defined in the inner vertical flange 140 that extends upward from the lower end 141 of the inner vertical flange 140. It will be appreciated that the slot allows for the vertical adjustability of the clip 111 (i.e., the slot 153 is configured to permit the clip 111 to be adjusted vertically based upon the location of the openings in the vertical stanchions 102, 103 configured to receive the fastener 154 coupling the clip 111 to the vertical stanchion 102, 103). In one embodiment, the stanchions 102, 103 of the battery support rack 101 may include pre-existing holes (e.g., holes configured to attach other components to the stanchions 102, 103) and the slot 153 allows the clips 111 to be adjusted vertically such that the existing holes in the stanchions 102, 103 may also be used to couple the clips 111 to the stanchions 102, 103 of the battery storage rack 101. In another embodiment, new holes may be drilled into the stanchions 102, 103 to attach the adjustable clips 111 (e.g., the stanchions 102, 103 may be retrofitted to include openings configured to receive the fasteners 154 coupling the clips 111 to the stanchions 102, 103 of the battery rack 101). Although the aperture 153 in the illustrated embodiment is a slot, the aperture 153 may have any other suitable shape, such as, for example, a plurality of spaced apart holes. In the illustrated embodiment, the flanges 140, 143, 146, 149 and the lip 152 are all thin plates. Each adjustable clip 111 may be formed by any suitable means, such as, for example, bending, stamping, pressing, machining, molding, extruding, rapid prototyping using additive manufacturing techniques, or any combination thereof. Each clip 111 may be made of any suitably strong material, such as, for example, aluminum, steel, alloys, carbon fiber reinforced plastic, or any combination thereof.

-11-, When the spill containment assembly 100 of the present disclosure is installed, the outer vertical flanges 146 on the adjustable clips 111 are configured to overlap the butt joints 139 defined between the straight wall segments 109a and the corner wall segments 110, as illustrated in FIGs. 1 and 2A. Accordingly, the adjustable clips 111 are configured to couple together the two straight wall segments 109a along each of the two longer sides of the spill containment assembly 100. The adjustable clips 111 are also configured to couple the two straight wall segments 109a along each of the two longer sides of the spill containment assembly 100 to the corner wall segments 110. As illustrated in FIGs. 1-3, the adjustable clips 111 are also configured to space the straight wall segments 109a, 109b and the corner wall segments 110 away from the stanchions 102, 103 of the battery storage rack 101 by a suitable distance, such as, for example, approximately 1 inch to approximately 4 inches (i.e., the adjustable clips 111 are configured to space the border or perimeter of the spill containment assembly 100 away from the stanchions 102, 103 of the battery storage rack 100). Spacing the straight wall segments 109a, 109b and the corner wall segments 110 away from the battery storage rack 101 may be necessary to comply with various federal, state and/or local regulations. Additionally, the upper flange 143 of the adjustable clip 111 may be configured such that the spacing between the stanchions 102, 103 of the battery storage rack 101 and the wall segments 109a, 109b, 110 of the spill containment assembly 100 is adjustable.
In addition, the adjustable clips 111 are configured to couple the straight wall segments 109a, 109b and the comer wall segments 110 to the stanchions 102, 103 of the battery storage rack 101 rather than the floor. Coupling the straight wall segments 109a, 109b and the corner wall segments 110 to the stanchions 102, 103 of the battery storage rack 101 eliminates the necessity of drilling a series of holes (e.g., hundreds of holes) into the floor or substrate in order to install the spill containment assembly 100 or at least reduces the number of holes that need to be drilled into the floor or substrate to install the spill containment assembly 100.
Drilling a series of holes into the floor or substrate may be time consuming, labor intensive, and expensive. Additionally, the floors in many older facilities contain asbestos, and therefore drilling into the floor may release asbestos fibers into the air, thereby posing a health risk to workers. Furthermore, coupling the straight wall segments 109a, 109b and the comer wall segments 110 to the stanchions 102, 103 of the battery storage rack 101 enables cost-effective

Finally, coupling the straight wall segments 109a, 109b and the corner wall segments 110 to the stanchions 102, 103 of the battery storage rack 101 eliminates the necessity of defacing the floor or substrate, such as by drilling holes or applying adhesive.
With reference now to FIGs. 5A and 5B, an adjustable clip 200 according to another embodiment of the present disclosure is illustrated. One of the corner wall segments 110 is omitted in FIGS. 5A and 5B to reveal one of the adjustable clips 200. Unlike the clip 111 described above with reference to FIG. 3 that is a single component, the clip 200 illustrated in FIGs. 5A and 5B includes two components 201, 202 configured to be coupled together by a fastener 203.
