Using Secondary Containment Systems To Protect Life And Health

Using Secondary Containment Systems To Protect Life And Health


by Karyn Shields


Most things that we enjoy require the use of substances that may be dangerous if leaked into the surrounding land. Too many news stories are about a truck leaking oil or some chemical onto the road while being transported. This can make the road dangerous and also damage the environment along the side of it. If properly installed, secondary containment systems will provide a better chance of it not getting out there at all.

There are as many differing systems as there are primary containment systems. These are based on a couple of considerations. When designing a system whose primary purpose is to catch something that escaped its primary containment, the material it is fabricated from is important. It must be able to withstand whatever effects would damage something else. In other words, it must be immune from any deteriorating action the substance generates.

One example of this type of system, and the particular material is used can be found in your home. The large trash container you have, probably in your kitchen, has to be removed from time to time to take outside. You are going to make it safer by placing the full bag into another plastic liner so that nothing will break through and fall on the floor. Plastic works for the primary and plastic works for the secondary.

It was an easy choice about that containerization. When looking at industrial and transportation systems, it gets more complicated. Decisions, in these areas, require looking into flexible or rigid construction. There is also the consideration about temporary versus permanent installation.

Some of the most often heard about accidents, resulting in spills or leaks that clog up traffic is gas and oil transported by truck. The tank is damaged and the leak, if not captured by a bladder system that most of these vehicles should have installed gets all over the road. This bladder is a flexible containment system and is required by laws and regulations in every area of the country.

In the case of trucks carrying oil or gas, a flexible bladder of a non reacting, inert material encases the hard tank. This is done so that any leaking that occurs from the primary tank is caught in this bladder. This saves the area surrounding the tank from being engulfed in this potentially dangerous liquid. It works because there is a good system and a back up system.

The rigid fabrications can be illustrated with retaining walls that are erected around a pallet holding large tank of chemicals. This will ensure that any leaks that occur, for whatever reason, will not get past this cement barrier to contaminate any other areas or people. In some industries and for smaller containers, this might simply be a curb that will still see chemicals not escaping this small space. There will be a small amount of cleaning and decontamination, but not the same as if there were no barriers.

Environmental Protection agency as well as Food and Drug, both have regulations that mandate these types of redundant protections against damages occurring from dangerous substances getting loose. These regulations require very exacting clean ups and reports as well as a certified inspection, usually by them, of the area before it can be released for further use.
