The field of the invention is spill containment systems and methods, and more particularly, is systems and methods for containing, neutralizing and/or monitoring spills from batteries or other devices.
In our industrial society, devices often contain substances that may leak or spill undesirably onto other devices, personnel, or the environment. For example, batteries may be stored on battery racks where the batteries serve as a backup power supply for data communication centers and computers. These batteries may contain acid 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 the federal, state and local governments. With respect to batteries, Article 64 of the Uniform Building Code requires a four-inch high containment barrier with an acid neutralization capability to a pH of 7-9. Similarly, other devices may need containment systems. Such devices include but are not limited to air conditioning units that may drip water from condensation or leak freon, or water heaters that may leak water.
Regardless of the device and the substance that may leak, it is desirable to contain leaks and spills. It is further desirable to neutralize and absorb the leaks and spills to prevent the leaks and spills from spreading. Finally, it is desirable to have a system that not only detects leaks, but also indicates whether a leak has occurred.
A battery rack system and method are provided including a battery rack for holding a plurality of batteries. Further included is a liner-equipped containment system connected to the battery rack. The containment system is adapted for containing leaks or spills from the batteries.
The subject invention is a spill containment system and method.
An optional corrosion resistant liner 24 may be inserted into the containment rail system 20. In particular, the corrosion resistant liner 24 is preferably fabricated of PVC with dielectric welded or thermal welded seams. For example, the material of the liner 24 may be coated with PVC on one side over a polyester web. As another example, the liner 24 may be fabricated out of a PVC thermoplastic material available as model C3000 (or C3 membrane) sold by Cooley Roofing Systems, Inc. (http://www.dupont.com/industrialpolymers/roofing/cooley.html) Model C3000 has been used in the roofing industry, but not in spill containment systems. As yet another example, the liner 24 may be fabricated out of a composite material such as a PVC-copolymer alloy composite. An example of a PVC-copolymer alloy is available from IB Roof Systems (http://www.Ibroof.com). Another example is a thirty-two ounce polyurethane available from FOSS Environmental and Infrastructure Inc. in Seattle, Wash. (http://www.fossenv.com). An embodiment of the liner 24 may have a thickness, for example, of 50 to 80 millimeters. Certainly, other thicknesses are permissible.
Alternatively, the liner 24 may be fabricated out of vinyl or any other material that is resistant to damage from the spilled substance. The liner 24 is cut and welded at its seams to form a liner of a desired shape. The liner 24 can be heat welded, or more preferably, dielectrically welded. Preferably, the liner 24 has an edge which rises about four inches to create a containment perimeter. The corrosion resistant liner 24 is preferably placed within the perimeter formed by the containment rail system 20, although the liner 24 could be mounted to the containment rail system 20 or be formed integral with the containment rail system 20. The battery rack 12 is then placed in the liner 24, mounted through the liner 24 to the containment rail system 20, or mounted through the liner 24 to the floor directly. Pillows 18 and socks 22 are optionally placed in the liner 24. If a liner 24 is not used, the optional pillows 18 and socks 22 may be placed within the perimeter formed by the containment rail system 20. Batteries may then be stored on the battery rack 12.
Advantageously, the spill containment system 10 may be configured to have any desired shape or size.
Containment rails are mounted together to form the containment rail system 20. A corrosion resistant liner 24 is optionally inserted into the containment rail system 20. A pad 44, also shown in
In this particular embodiment, the containment rail system 20 may have a height of three inches; the liner 24 may have a height of four inches; the pad 44 may have a thickness of a quarter inch; and the grid may be one-sixteenth of an inch thick. Of course, as with any of the embodiments and examples described in this patent specification, the dimensions, size, shape and/or configuration of the spill containment system and any of its components may be changed as desired for the particular application.
Additional features are possible. For example, a leak detection device 60 may detect and indicate whether a leak or spill from a device has occurred.
We now turn to the components that form a containment rail system 20.
The containment rail 76 may be an adjustable containment rail 82, as shown in
A corner containment rail is illustrated in
While any mounting components may be used to secure the spill containment system to the floor,
While the spill containment system has been proposed for containing acid spills from batteries, it can be used to contain spills from any device such as air conditioning units (which may leak water or freon), water heaters (which may leak water), or any other device. Moreover, it is not limited to containing and/or neutralizing acid spills as it can be used to contain and/or neutralize any kind of spill including a non-acidic spill.
While embodiments and implementations of the subject invention have been shown and described, it should be apparent that many more embodiments and implementations are within the scope of the subject invention. Accordingly, the invention is not to be restricted, except in light of the claims and their equivalents.
This application is a continuation of U.S. patent application Ser. No. 09/960,759, filed on Sep. 21, 2001 now U.S. Pat. No. 7,124,771 which is, in turn, a continuation of U.S. patent application Ser. No. 09/428,192, filed on Oct. 27, 1999, now issued under U.S. Pat. No. 6,308,728, which are fully incorporated herein by reference.
