While both spill decks and spill pallets are designed to contain hazardous material spills, they differ in design, containment capacity, and primary use:

Design and Size:

Spill Pallet: Typically larger and has higher sides to contain a larger amount of liquid. Spill pallets often come in 1, 2, or 4-drum configurations, with taller walls to accommodate large spills.
Spill Deck: Lower to the ground with minimal or no walls, designed to hold fewer drums. Spill decks are often modular, allowing multiple units to be connected to form a larger containment system.
Containment Capacity:

Spill Pallet: Designed to hold more liquid, typically 30 to 100+ gallons, depending on the model. They meet EPA and SPCC requirements for secondary containment, holding at least 110% of the largest drum’s volume.
Spill Deck: Holds a smaller volume of liquid, usually between 10 and 30 gallons, suitable for smaller spill containment needs. Spill decks are ideal for low-profile storage.
Primary Use:

Spill Pallet: Commonly used in industrial settings for long-term storage of larger drums and IBC totes. They are built to handle heavy loads and more substantial spill events.
Spill Deck: Ideal for temporary use or smaller spill prevention tasks. They are more flexible for light-duty storage and often used in spaces where height clearance is limited.
Weight Capacity:

Spill Pallet: Can support heavy loads of up to 5,000 pounds or more, making them suitable for full drums and totes.
Spill Deck: Typically supports lighter loads, ranging from 1,000 to 2,500 pounds, and is used for smaller drums or containers.
In summary, spill pallets are better suited for larger, heavier containers and higher spill capacities, while spill decks are used for smaller, low-profile containment needs.
