Some Information On Spill Containment Berms

By Tracie Knight


Lately anywhere around the world there will be some form of oil spill at sea or even in land. Now and again you will hear of a tragic ferry or maritime disaster that has some form of oil or liquid pollution involved. When this happens, spill containment berms are used to contain the spill, in cases spanning several miles.

Berms have been existence since man learned how to construct things. They have been used as gutter channels and guides in irrigation projects by American Indians long ago and also have been in use by people in the medieval ages. They are very useful in guiding and containing waste material, whether liquid or not.

Spills differ in terms of behaviour and also in terms of the danger that they pose. Spill containment equipment such as berms are also specifically designed for the kind of spill they are meant to contain, which are usually categorized in terms of toxicity and viscosity. Although they can come in a range of sizes and shapes, the most common one will see are usually rectangular or square sheets hemmed in by four raised embankments.

Envision in your mind a very shallow pool for children raised a very few inches from the ground. This are basically what they are. Low and shallow embankment berms are usually designed for high impact situations and are very durable. These are usually the kinds you will see in at an oil spill on the road. Mainly these are used for leaks occurring from chemical trucks and fuel trucks wherein they are placed underneath the tank or carriage, which can occur when discharging operations take place.

The walling for these units used for roadside containment should have an open cell foam interior. This kind of foam and construction will see the wall spring back to its original shape as soon as something passes over it like a vehicle tire. This is very much needed in roadside applications.

Square and rectangular designs and outlays are most commonly used for flat even surfaces. But spills do not only occur on very even surfaces. They can basically occur anywhere and this can include rough and uneven surfaces of differing porosity and the like. Thus there are berms created and designed for these more unique elevations with more flexible matting and custom made connectors for interior walling and embankments.

Higher specialty designs have better liquid tight construction and also better adapted to uneven and rough surfaces such as will be found in gravel rich surfaces and rocky areas. They are extremely durable and rough terrain do not easily crack them or put small pinholes. Likewise, most of these containment units are bio degradable and can be thrown away efficiently once used.

It is fairly simple to find some stores selling these. All you need to do is to type out spill control specialists and equipment in the Internet and you should get some hits. You can also do the age old method of going through the Yellow Pages if that is more to your liking.
