Spill pallet
A spill pallet is a bunded secondary containment item that is designed to hold containers of oil, hazardous liquids, and fuels, typically in either a drum or in an intermediate bulk container. It is called a 'secondary containment item' because it is designed to catch the leaks and spill of the container's contents which rest upon it.
The spill pallets can come in a variety of sizes to accommodate multiple containers. Several designs have been developed.
UK legislation
In the UK, a container of oil or fuel cannot be stored outside unless it is bundled in a secondary containment item. This means that if the container of oil leaks, it will be contained within the bund. The secondary containment item must be able to hold 110% of the largest container above.If a person were to store 4×200-litre drums on the sump pallet, the sump pallet must be able to hold of oil.
Although there are no laws in the UK stating that a sump pallet must hold 110% of the largest container upon it, it is still considered good practice to do so.
