Store large quantities of liquid in these flat-bottomed tanks. They have vented fill caps so air can flow in and out.

When spills happen, these pallets contain the mess. They’re made of polyethylene, so they won’t degrade from most chemicals. They also meet EPA standards for liquid storage. To minimize potential leak points, these pallets are built without a drain. You’ll need to pump or clean out liquids after a spill—remove the grating to access the interior.

When choosing a pallet, consider the surface area and capacity you need. For number of 55-gallon drums gives you a sense of the surface area of your pallet, while capacity tells you how much liquid it can hold. When used correctly, these pallets meet EPA 40 CFR 264.175. Choose a pallet that’s large enough to hold either 10% of the total capacity of all the containers on it or the full capacity of the largest container—whichever is greater.
