What Is a IBC and Tank Spill Containment?
Secondary spill containment for IBC totes and bulk tanks is a rigid or collapsible structure — a pallet, sump, or berm — placed under the storage vessel to capture the full contents in the event of a leak, valve failure, or tank rupture, preventing the liquid from reaching soil, floor drains or waterways. Under EPA's SPCC (Spill Prevention, Control, and Countermeasure) rule, secondary containment for bulk storage is generally required to hold the volume of the largest single container plus sufficient freeboard for precipitation where containment is outdoors, not merely a fraction of the tank's capacity.
Containment capacity, chemical compatibility of the containment material (usually polyethylene) with the specific stored liquid, and grating or platform load rating for foot and vehicle traffic are the key selection factors. A containment pallet or berm rated for one chemical family (e.g., most polyethylene units resist common acids and bases well) may degrade or fail against an incompatible chemical, so material compatibility should be checked against the actual product stored, not assumed from general secondary containment marketing.

| Spec | What It Means | Why It Matters |
|---|---|---|
| Containment Capacity | Must equal or exceed the largest single vessel's volume | SPCC and most fire/environmental codes require full single-container capacity, not partial |
| Tank/Tote Configuration | Single IBC, double/multi-IBC, drum, bulk tank berm | Determines footprint and whether a dispensing or access platform is needed |
| Material Compatibility | Polyethylene compatibility with the specific stored chemical | An incompatible material can degrade, crack or fail on contact with certain acids, solvents or oxidizers |
| Grating Load Rating | Rated for foot traffic vs. forklift/vehicle traffic | Understating load rating risks grating failure under actual site traffic |
| Portability | Rigid molded pallet vs. collapsible/foldable berm | Collapsible berms suit temporary or repositioned containment needs; rigid pallets suit fixed installations |

FAQ
IBC and Tank Spill Containment Questions, Answered
How much containment capacity do I actually need for one IBC tote?
Under EPA's SPCC rule and most fire codes, secondary containment must generally hold the full volume of the largest single container being contained — for a standard 330-gallon IBC tote, that means at least 330 gallons of containment capacity, not a fraction of it. If containment is located outdoors, additional freeboard capacity for precipitation is typically also required.
Does the containment pallet material need to match the chemical being stored?
Yes — most containment pallets and berms are molded polyethylene, which resists a wide range of common chemicals including many acids and bases, but is not universally compatible with every chemical (some solvents and strong oxidizers can degrade certain plastics over time). Check the containment manufacturer's chemical compatibility guidance against the specific product stored before relying on it.
What's the difference between a rigid containment pallet and a collapsible berm?
A rigid molded containment pallet is a fixed, permanent structure best suited to a stationary tote or tank that won't be relocated. A collapsible or foldable berm can be set up, taken down and moved between locations, making it better suited to temporary storage, job sites, or situations where the containment footprint needs to change periodically.
Can I drive a forklift over containment grating to load or unload totes?
Only if the specific grating is rated for that load — standard foot-traffic-rated grating can crack or fail under forklift weight, while forklift- or vehicle-rated grating is specifically reinforced for that purpose. Always confirm the grating's rated load capacity matches the actual traffic it will see before assuming a unit is drive-over rated.
Do I need a dispensing platform with my containment unit?
A dispensing or access platform is worth adding if personnel need to regularly access valves, fittings or the top of the tote/tank for sampling or dispensing product, since standing directly on the containment sump or reaching over it can be awkward or unsafe otherwise. Fixed storage with infrequent access may not need one, while active dispensing operations typically benefit from an integrated platform.
