Choosing the Right Bunding and Spill Containment Solutions for Your Site
Most sites holding liquids work on two layers. Bunding is the first: the drum sits on a bunded pallet, the IBC sits over a moulded sump, the decanting area sits inside floor bunding, and anything escaping is held in the containment volume underneath. That is passive protection, working whether or not anyone is watching. Chemical bunding and pallet bunding both describe the same principle applied at different scales, from a two-drum bund up to a triple IBC footprint.
Spill kits and absorbents are the second layer, for the spill that happens outside a bund or overtops one. A failed valve during decanting, a dropped container on a hardstand, a leak in a transport yard: none of those land conveniently inside a sump. General purpose, oil and fuel, hazchem and marine kits each match a different liquid profile, and loose absorbents keep kits stocked while handling the routine drips that would otherwise run a kit down.
Specifying across the range starts with what is stored, in what containers, and where. The number and size of containers set the bund footprint. The products held set whether poly bunding or a specific absorbent grade is appropriate. Whether the area is covered or exposed decides if covers and shrouds are needed, since an open bund collects rainwater and water in a sump is capacity no longer available for a spill. Flammable storage cabinets handle the separate question of where flammable liquids sit when not in use. Confirm the containment capacity and storage arrangements you specify meet the requirements that apply to your site and the class of liquid being held.
