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 200-litre (44 imp gal; 53 US gal) drum or in an intermediate bulk container.
The spill pallets can come in a variety of sizes to accommodate multiple containers.
[4] If a person were to store 4×200-litre drums on the sump pallet, the sump pallet must be able to hold 220 litres (48 imp gal; 58 US gal) 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.
Sump pallets can be made in a variety of materials, but due to the nature of the oils or chemicals which will be stored upon it, they are typically made from either UV stabilised polyethylene, or steel that is galvanised for further protection from harsher chemicals.
