Pallet Rack Sumps and Inserts
(9 Article in 9 variants)Pallet rack sumps and sump inserts allow facilities to retrofit existing pallet rack systems with compliant secondary spill protection. Designed for drum and IBC storage on pallet racking, these galvanized steel solutions capture leaks either within rack levels or beneath the rack structure. By adding pallet rack sump inserts or beneath-rack spill containment sumps, facilities can help meet SPCC, OSHA, and NFPA requirements without replacing existing racks.
Retrofit Spill Containment for Existing Pallet Racking
Facilities often rely on standard pallet racking systems that were not originally designed to provide secondary spill containment. When storing drums or IBC totes containing hazardous liquids, these racks may require additional protection to meet SPCC, OSHA, or NFPA requirements. DENIOS offers two retrofit spill containment solutions to help bring existing pallet rack systems into compliance: pallet rack spill trays, which are galvanized sump inserts that install directly within rack levels, and base-level pallet rack sumps that sit beneath the racking structure. Both options provide durable, leak-tested containment without requiring full rack replacement and are an integral solution when planning to store hazardous materials.
Galvanized Sump Inserts for Pallet Rack Levels
Galvanized sump inserts install directly within existing pallet rack beams, converting standard rack levels into compliant spill containment zones. Each insert includes a heavy-duty galvanized steel sump and removable grating that supports drums or IBC totes while capturing leaks below.
Available in common rack sizes with sump capacities ranging from approximately 58 to 79 gallons, these inserts provide an economical retrofit solution without replacing existing pallet racking.

Pallet Rack Spill Containment Sumps (Base-Level)
Base-level pallet rack sumps are installed beneath existing rack systems to capture leaks from containers stored above. Constructed from heavy-gauge galvanized steel, they provide secondary containment across an entire rack bay. Base-level pallet rack spill containment sumps can be retrofitted to existing racking and storage systems.
With capacities ranging from approximately 68 to 122 gallons, these floor-mounted sumps help facilities upgrade pallet racking systems to meet spill containment requirements.

Frequently Asked Questions about Pallet Rack Sumps and Inserts
What is a pallet rack sump?
A pallet rack sump is a spill containment tray installed within or beneath existing pallet racking to capture leaks from stored drums or IBCs.
Can pallet rack sumps be retrofitted to existing racks?
Yes. Both in-rack inserts and base-level sumps are designed to retrofit pre-existing pallet rack systems.
What containers can be stored on pallet rack sump inserts?
These systems are commonly used for drum and IBC storage applications. They may also be referred to as a rack sump tray.
Do pallet rack spill containment systems meet SPCC requirements?
DENIOS pallet rack sumps are engineered to meet SPCC, OSHA, and NFPA guidelines for secondary containment.
