Spill Containment Ways And Methods

By Nina Gallagher


When you drop some liquid on any surface the first thing you do is clean it immediately. Fears of spoiling the surface, attracting insects, flies and expenses of restoring the surface/material prompt you to act soon. Liquid that can be re-used you collect in another container. This is an example of ordinary spill containment.

The thought of gallons of fluid running helter-skelter can be frightening. Such occurrences can create havoc if due action is not taken immediately. Vast areas can be spoilt and numerous lives can be put at risk.

Pipes carrying water, sewage waste or oil usually run under the ground. Chances of a burst in one of them are a possibility and the sewage pipe bursting can be alarming. The spill can affect the water pipes, if they are near or be absorbed by the soil and mix with the ground water. In such instances, you may wish for damage control measures to be implemented right away.

Plants and sea creatures living under the sea survive on the sunlight penetrating the surface and the atmospheric oxygen. However, when oil tankers loaded with the expensive fluid have ruptures in the open sea, the death toll starts ringing for these living beings under the surface of the ocean. The oil fans out on the open water surface and since it does not sink in, it blocks the necessary sunlight and oxygen supply. Very few sea creatures probably can escape the doom looming overhead.

Similar accidents can occur at off-shore oil rigs, spewing oil over a wider radius and blocking the lifeline of sea inhabitants. This sort of incidents cause great havoc to the ecological balance - vast numbers of under-sea plants, fish and other creatures die gasping or swallowing the slick oil. The ripple effect of such incidents is immense.

Unnecessary spillage of any fluid in the wrong place can only bring destruction, wastage and expenses. So the world over, companies are looking for ways and means to control such situations in the best manner possible, causing the least harm to the atmosphere. In some cases absorption and discarding of the liquid is wise, but it does not make sense with liquids that can be used or recycled.

Finding useful ways to contain the spilled liquid gives it a new life, besides stopping any further damage to other living beings and the ecosystem. Bladders, valves, stoppers, remote controlled processes and robotic applications are all being applied in the spill containment method today. A sewage pipe burst will of course need stoppers and not any system to recycle the fluid.
