Secondary containment is a backup system that captures leaks, spills, or overflows from tanks, drums, totes, and other liquid storage containers before they spread into the surrounding area. It helps protect workers, equipment, and the environment while supporting safer storage practices.
For companies that store fuel, oil, chemicals, or industrial fluids, secondary containment is an important safeguard. A single leak can create cleanup costs, safety hazards, operational delays, and environmental exposure. With the right containment system in place, those risks are easier to control.
Why Secondary Containment Matters
The purpose of secondary containment is simple: if the main container fails during storage or transfer, the spilled liquid stays contained.
That protection can help businesses:
Reduce the risk of soil and water contamination
Protect employees and equipment nearby
Limit cleanup costs and downtime
Improve spill preparedness
Support compliance and site safety standards
In many industrial and commercial settings, secondary containment is a standard part of responsible liquid storage.
How It Works
Every storage setup starts with a primary container, such as a tank, drum, or tote. Secondary containment adds a second layer of protection around or beneath that container. If a leak, rupture, or overflow occurs, the containment system captures the liquid and prevents it from spreading.
Common examples include:
Spill pallets
Containment berms
Double-walled tanks
Sumps
Lined containment areas
Custom containment systems
The right option depends on the material being stored, the volume involved, and the conditions at the site.
Where It Is Commonly Used
Secondary containment is used anywhere liquids could pose a safety or environmental risk if released. Common applications include:
Fuel storage areas
Chemical storage locations
Oil drums and totes
Generator and transformer sites
Loading and transfer points
Construction and industrial job sites
Fleet maintenance areas
What to Look for in a Containment System
A good secondary containment system should fit the application it is meant to protect. Key considerations include:
Compatibility with the stored liquid
Adequate capacity
Durability in harsh conditions
Resistance to punctures, weather, and wear
Easy inspection and maintenance
Not every product works for every site, which is why selecting the right containment solution matters.
Secondary containment helps prevent a leak from turning into a larger safety, environmental, or operational problem. For businesses that store or handle liquids, it is one of the most practical ways to improve protection and reduce risk.
