Which Secondary Containment System Is Right For You?

Secondary containment is an important safeguard that helps plant operators mitigate the risks associated with chemical spills and avoid damage to equipment and property. In this system, a secondary container or wall encompasses the primary container. Should the primary container fail and cause a chemical leak, the secondary container prevents the chemical from spilling outside the system.

While there are several options that may be the best choice for your facility or company, let’s explore three of the most well-known secondary containment systems.

3 Types of Secondary Containment Systems

1. Concrete Containment

One of the more traditional solutions for secondary containment, concrete containment, consists of a poured containment foundation that is combined with vertical concrete walls. Once poured, the interior is typically coated with a barrier substance in order to prevent spilled chemicals from eating away at the concrete. 

2. Polyethylene Containment Basin

For a more cost-effective solution compared to a concrete containment system, polyethylene containment basins are a good alternative to consider. In this system, a polyethylene chemical storage tank is placed inside an open-top tank. The open-top feature is the reason much of the primary and maintenance costs are eliminated when compared to concrete units. 

3. SAFE-Tank®

What we consider the safest solution is the SAFE-Tank, or a “tank-within-a-tank, that provides a fully enclosed secondary containment. In the event of a spill or leak, a SAFE-Tank provides safety and peace of mind for your investment, your plant, your employees, and the environment. In the case where a primary tank develops a leak, the chemical or liquid is captured by the sealed secondary tank. This allows the system to essentially become a single-wall unit until the chemical in the inner tank is used up and the tank can be repaired

What Containment Solution is Right for You?

Selecting the wrong secondary containment system can result in unplanned and unnecessary expenses, additional maintenance, and increased operational stress.
