What is secondary containment?
A primary container is the vessel that holds the hazardous substance, for example a bottle, 20L container, 200L drum or 1,000L IBC (intermediate bulk container). Secondary containment could be best described as the system in place to contain spills, leaks or the failure of the primary container stored on it.
Why is it required?
In the many workplaces storing or using hazardous substances, the primary containers that hold such liquids are vulnerable to damage. This vulnerability can come from poor storage practices, mismanaged decanting or transfer procedures, or damage from vehicles such as forklifts.
Once over a certain threshold, a secondary containment system is often required by legislation to contain these hazardous liquids if they escape from the primary container, and to prevent them from escaping into the wider environment.

That environment might be the immediate workplace and therefore may put employees and other personnel at risk. Or it might be a nearby waterway which will quickly pollute and impact marine and bird life, as well as their ability to be used for domestic, commercial, or recreational purposes.
How is it achieved?
Secondary containment has been historically achieved by building ‘berms’ from concrete or block walls, earth mounds or large tubs. In recent years however, it has been made much less complex with low profile work floors, spill containment pallets and flexible bunding options. These are designed to be quickly repositioned as your site and operational requirements change over time.
