EPA Regulations
Any liquid that shouldn’t be poured down a drain should be stored safely and in compliance with Federal, State and Local Government regulations - most commonly, in or on a bund. Liquids that are kept unbunded also pose a slip hazard in the workplace. If liquids aren’t stored safely, your worksite is probably non-compliant.
How big should your bund or spill pallet be?
This is one of the most common questions asked around bunding. And while local regulations may differ, typically in Australia the requirements are that the bund capacity should be whichever is greater of 110% of the largest container or 25% of the total stored on the bund. Which sounds confusing! However, to make it simple, all our 205L drum and 1,000L IBC bunds are designed to comply with these regulations:
As you can see, the 110% rule applies in every situation listed above, but not always when storing smaller drums:
Also, 1000L IBCs cannot be stored on a four drum bund:
Incompatible Liquids
Incompatible liquids should not be stored on the same bund, as they will mix in the sump if both containers were to leak.
Outdoor Storage
Rain can quickly make outdoor bunding non-compliant. Best practice could include regular, scheduled pump-outs, or bund covers to prevent rainwater entering the bund sump.
