Why are pallets called a 'Secondary Containment Item'?

Posted on

A pallet is called a 'secondary containment item' because it is designed to catch leaks and spills and minimise the consequences of a failure in the primary containment system by preventing the uncontrolled spread of the hazardous substance.

A Spill Pallet is a bunded secondary containment item that is designed to hold chemicals in drums, IBCs or containers.

Examples of secondary containment items:

  • IBC Bunds
  • Drum Bunds
  • Portable Bunds
  • Covered Bunds
  • Drip Trays


Oils and chemicals need to be captured immediately so that they never reach the environment. Bunds will contain leaks and spills before an incident escalates out of control.

No matter whether the pallets are made of steel or plastic, they are built to contain leaks, drips or spills. The typical design includes a grid on which the IBC, drum or container(s) sit, with a sump below the contents will flow during a spill. 

All bund sumps hold 110% of the total stored or 25% of the combined total stored (whichever is greater) to allow for additional liquids such as rainwater or overfilling of the containers. It also reduces the chance of liquid overtopping the side of the bunds where the contained liquids are a dynamic load meaning the liquid inside the bund is not static, causing a wave effect.

Drip Trays

Drip trays are specifically designed to catch leaks and drips making them an important part of any spill containment plan. They are especially useful for preventing liquids from contaminating floor space which can then spread and contaminate machinery, products or the environment. Spill trays are available in a range of sizes to suit most applications.

They are highly convenient for being relocated & can be stored almost anywhere thanks to their size & weight, making them ideal options for taking along with machinery or to remote locations off-site. They are also incredibly useful when dispensing into containers to help catch any spills or overflows. 

Drip trays are used to host smaller containers such as paint cans or bottles to temporarily contain any leaks or drips. Each tray has a broad chemical compatibility allowing them to be used with a wide range of different chemicals, oils & lubricants.

The grid elevates the base of any containers out of any loose liquids caused by drips, spills or leaks and because it nests well this drip tray takes up less space when being stored or transported. The grid's surface improves resistance against the containers improving stability when stored.
