One who needs containment berms has to know what types of them are available. Most get them to comply to Federal or State regulations. These regulations are mostly derived from 40 CFR enforced by the EPA which is a part of its act on ensuring clean water. Since not all of them are similar, knowing the different types will help with the selection process.
To aid in selecting with different choices of materials available, one must define his purpose first. Provision 40 CFR was made to define equipment types that will handle oil and hydrocarbon materials. According to the regulation, containers should be capable of handling the full 100 percent volume capacity of largest container present. Another ten percent will be added to that volume. This added ten percent is an allowance for rainwater if any rainfall will happen. This prevents materials from leaking.
If secondary containers are needed, the volume capacity should be decided on. The volume can be gained by computing the height, width, and length of the berms. Some areas may be very small. In this case, one can increase the height of container walls, and the length and width customized to fit area. Manufacturers may be asked to do this.
The materials these containers may made from could be steel, concrete, film, or coated fabrics. Most are made of coated fabrics as they are more compatible with chemicals that most are using. Films are cheaper and are mostly made from polyethylene and are meant for one use only as they crack and break easily when folded. For permanent use, coated fabrics, concrete, and steel having special coatings are the best choices.
The concrete types are more permanent. However, they could not be moved as they are fixed in one area only when installed. Secondary containers will then be needed. Expanding them is not an option. Sealing is required to make them impervious to leaks. Given the price and maintenance, most are discouraged of using them.
The steel versions offer best choices when longevity is considered. They have special coatings which make their surfaces resist damaging factors such as different weather changes and rusting. Unlike concrete, they are portable. However, it is not easy. Cranes are required for transferring them. The pieces should have no seams where leaks are more likely to occur.
Those constructed with coated fabrics have certain advantages when compared to others. They are extremely portable. Installing them will not take long. Permits are not required of them and they can offer a long term solution given that they are cared for properly. In terms of cost effectiveness, they are better than steel and concrete.
The use of fabric type is also common. There are different types of them. These may be polyvinyl chloride, modified polyvinyl chloride, or polyurethane. However, compatibility with contained chemicals requires important considerations. Hydrocarbons and oils cause fabric leach of the plasticizers in polyvinyl chloride materials. Modified PVC types and polyurethane are better to handle hydrocarbons but generally cost higher.
Anyone handling chemicals must be responsible in taking care when handling them. This includes having the necessary precautions that will address to accidental and simple leaks. Containment berms were designed for that purpose. One should take enough time in selecting them to ensure proper selection to safely contain them.
