Spill Containment Systems Information

Spill containment systems are used to capture and contain unintentional spills of liquid media. They are also called secondary containment systems. Typically, spill containment systems use a physical and/or chemical barrier to prevent fluids from permeating the soil and migrating away from an industrial or commercial site. Spill containment barriers can also be placed under or around a truck, storage tank, or similar vehicle or vessel to prevent gasoline, oil, and chemicals from permeating the soil and contaminating the surrounding area. Spill containment systems that provide a physical barrier are usually made of plastic, fiberglass, concrete, metal, or rubber. These secondary containment systems include barrier dams and barrier dam liners. Barrier dams are easy-to-assemble modular systems that are designed for use with absorption pads and neutralization pads.


Barrier dams that are made of stainless steel are corrosion-resistant and may comply with fire codes and standards from the Occupational Safety and health Administration (OSHA) and the Environmental Protection Agency (EPA). Barrier dam liners are also corrosion-resistant, and provide an alternative to surface coatings. Spill containment systems include dikes, tubs, mats, moats, modular systems, tracks, curbs, bladders, and pads. Dikes and tubs may be used instead of concrete walls as secondary containment systems for storage tanks. Mats, moats, and modular systems are designed to contain incidental spills that may occur during truck transfer operations. Tracks are a type of modular system for containing spills during railcar transfer operations. Curb spill containment systems are a type of low-walled dike for containing spilled liquids. Trucks and tankers drive and park on containment pads, typically during fueling or refueling operations.


There are many different applications for spill containment systems. Some products are used for fuel-oil storage on farms, at truck storage areas, or at gasoline stations. Others are designed specifically for truck, tank, or railcar containment. Many truck containment systems use surface-mounted, corrosion-resistant containment pads that can be joined together to create larger configurations. Tank containment systems include dikes and tubs of varying heights and depths. Dikes may be used as a stand-alone containment system, or with a floor laminate or liner. Railcar spill containment systems include modular tracks that can be assembled using hand tools.
