The Chemtainer 66-inch spill pan (SKU TC6608OA) is a low-profile polyethylene containment base built to sit under a drum cluster, tote, or small tank and catch drips, overflow, and incidental spills before they reach the floor or a drain. It measures 66 inches across and stands just 8 inches tall, giving you a wide 66.0 x 66.0-inch footprint that suits a multi-drum arrangement while staying easy to step over and simple to inspect. Molded in Dark Grey polyethylene at an empty weight of 48 pounds, it is one-person maneuverable and holds its shape under repeated wash-down and loading.
What it does and how it fits your layout
Poly construction handles the wet, splash-and-drip duty that ruins painted steel pans, and the round shape drains and cleans out cleanly with no square corners to trap sludge. Because the pan is open and shallow, plan your layout around the 66-inch outside diameter - but size your drum cluster to the usable inside circle, which is smaller than the 66-inch nominal once wall thickness and lip are accounted for. The technical drawing on this page gives you the exact profile, inside dimension, and lip height, so check those against your equipment before you order rather than assuming a full 66 inches of clear floor. If you are setting the pan on a slab, our guide to concrete pad sizing for above-ground polyethylene tanks covers the ACI 360R-10 framework for a level, durable base. Still deciding how much storage the pan needs to sit under? The Tank Sizing Calculator and Tank Sizing Guide help you match vessel size to the containment base.
The mistake to avoid
A spill pan is a catch basin, not a rated secondary-containment dike. The pan's usable containment is its geometric volume minus the displaced volume of every drum you set inside it, and the lip height on the technical drawing - not the 66-inch diameter - is the real limiting dimension. Do not treat this 8-inch-deep pan as meeting a specific containment-volume requirement until you have run that math and confirmed the pan captures the fraction your jurisdiction requires. Size the containment to your regulation, not to the pan's convenience. This is a drip-and-splash base first; use it as one and add a rated dike where code calls for one.
