Information About Secondary Containment Systems

By Marylou Forbes


The world is composed of both harmful and useful chemicals. Sometimes, even the sensitive and toxic ones are widely used in some industries. These liquids are used to be able to successfully create a certain product, or to make something work well and with utmost efficiency. Some industries use harsh chemicals that can cause pollution to the soil and the waters, which provides for the utmost need for secondary containment systems.

These secondary container systems are made to accommodate all these toxic wastes in a spill proof manner until the time comes when they are to be disposed of properly. Most containing methods employ the extensive usage of spill catch mechanisms for oil filled equipment, truck decks, fuel tanks, and everything that has a great tendency to be developing a leak.

It can also take on several forms, and bunds are only one of them. They are generally used around storage tanks or drums that hold flammable and possibly highly toxic liquids. They are also sometimes used in plant buildings for reactors, to hold gases in ambient conditions, and the like. They are generally fabricated from brick or mortar. Some are even made of concrete.

There are also some equipment, like in the case of some oil pipes, that have a high chance of developing leaks. For this reason, some companies use drip trays. They act as special basins that will inhibit the liquid substance from getting to parts of the field where they should not get to. Without these drip trays, oil and flammable liquids can get to other equipment and may cause massive fire if one is not careful.

Sumps are also known in the industrial world as interceptors. They include storm water drains, sewers, and firewater drainage systems. It is, in general, a low space that collects undesirable liquids, like some certain chemicals and water. It also serves as an infiltration basin that is often used for the management of surface runoff water and for the recharging of most underground aquifers.

Another kind comes in the form of concentric pipes. They are often characterized by having two sets of tubes fitted over each other. The outer tube is normally made of a very sturdy material that protects against containment loss. It is normally fashioned out of steel, as it is strong enough to contain something for a little more time.

Catch pots, precipitators, scrubbers and flares belong to the classification of off gas treatment methods. They are normally a part of the original system that can also serve as a secondary unit. These are often utilized for the reduction of concentrations of most vapors and gases.

Pressure and its control is a very integral part of most industrial process. This is why most factories have their own expansion systems. These units can prevent the build up of pressure that can cause overfilling. Reactors, pipelines, and liquefied gas storage are just some of the mechanisms that need to be attached with this expansion equipment.

Secondary spill systems must be designed, installed and operated in such a way that it effectively prevents migration of wastes and accumulated liquid. They should also be capable of collecting wastes until they are removed. Lastly, they should be separate from the primary equipment.
