Secondary spill containment is the containment of hazardous liquids in order to prevent pollution of soil and water
Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known liv ...
. Common techniques include the use of spill berm
A berm is a level space, shelf, or raised barrier (usually made of Soil compaction, compacted soil) separating areas in a vertical way, especially partway up a long slope. It can serve as a terrace road, track, path, a fortification line, a b ...

A fuel tank (also called a petrol tank or gas tank) is a safe container for Flammability, flammable fluids, often gasoline or diesel fuel. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine sys ...

Definition
Secondary spill containment involves the sequestration ofhazardous waste
Hazardous waste is waste that must be handled properly to avoid damaging human health or the environment. Waste can be hazardous because it is Toxicity, toxic, Chemical reaction, reacts violently with other chemicals, or is Corrosion, corrosive, ...

In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple Electrical network, circuits. A varying current in any coil of the transformer produces ...
s are often in need of secondary containment. Outdated secondary containment techniques such as concrete catch-basins are quickly losing ground to solutions that offer more cost-effective cleanup in case of a spill or leak. One example of a more cost-effective method involves placing a geotextile
Geotextiles are versatile permeable fabrics that, when used in conjunction with soil, can effectively perform multiple functions, including separation, filtration, reinforcement, protection, and drainage. Typically crafted from polypropylene or ...

around a transformer. These geotextile barriers allow for flow of water, but completely solidify oil in the event of a leak and effectively seal the spill. Many electrical utility companies are switching to this method because it saves them significant amounts of money when a spill occurs, because there is no need to employ vac-trucks afterwards to clean up a spill inside a catch-basin.
