Using Secondary Containment Systems To Protect Life And Health

By Karyn Shields


There are a lot of chemicals and other substances that make life worth living and help make it the best it is. Some of these substances, such as gas, oil and others are a danger to the environment if they are allowed to leak out of the container it is in. This is especially true when being transported. You have heard, many times, about a leak from a gas truck or an oil spill on a roadway. It snarled traffic and caused damage to the surrounding area with nasty, often flammable materials. Secondary containment systems, if in place, would have assisted in making sure this did not happen.

There are many different substances that must be contained so they do not harm people or the environment. No containment will work in a universal way. Determine what material should be used for this system as lives can depend on it and, certainly, the cleanliness of the areas is. The manufacturers who build these units do the testing and work hard to make sure they are safe for use.

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.

Protecting your home from trash was an easy example to deal with. Industrial storage and the transportation of substances are more complicated. This is because of additional considerations. The choice or need use rigid versus flexible containers will make a big difference in the type of materials and what can be done with each type.

A couple of these substances you hear about all of the time are the transport of gasoline and oil by truck or rail. The rigid primary tank for the transport for either one of these can tear or become punctured for many reasons, not the least common of which would be an accident. This has caused many gallons or barrels of environmentally unsafe material to be spilled out and endanger others due to the chance of fire or other accidents happening around them.

That bladder is made from a material that will not react with the substance. Whether oil or gas, there is no problems because of that. This saves the environment and prevents anyone close by to get drenched by something they really do not want on them for a host of reasons.

On the other side of things, a rigid containment system would look like a retaining wall erected around a tank of chemical. Occasionally this is simply a curb height fabrication of concrete or cement. This will ensure that, if something happens to the tank that causes a leak, it will turn into an actual spill that gets all over. There will still need to be a cleanup, within the walls or curb, however, it will be confined to that area alone.

If these substances, that are required by EPA and FDA, are not contained and allowed to spill into areas with people working, specific clean ups must be undertaken. The cleaning, decontamination and all of the inspections are mandated to be completed before the area can be used, again. By ensuring the spill does not happen, all of the major cleaning does not, either.
