They are also known as bunding trays. Spill trays and spill pallets are forms of spill protection barriers that are needed to protect people and the environment from hazardous chemical leaks. It is the most common type of bund. They are highly used for storing or pouring chemical containers.

For small chemical containers, spill trays act as secondary containment. You can easily find these in laboratories or research facilities. It is portable and allows safe decantation in a laboratory. In case a spill occurs, the tray comes to the rescue unless you remove the chemical from the tray easily.

Spill pallets are made from plastic, composite materials, and metal. It is a larger containment, available in a range of sizes, made to carry heavier loads like drums. These pallets are also easily portable.

2. Keep an Emergency Reaction Plan in case of a spill

The COMAH regulations state that you should have an ‘Emergency Reaction Plan in case of a spill’ ready at the workplace to deal with situations. The plan should include a process to regulate chemical incidents to reduce the effects and threats on the employees working as well as the environment.

4. Preserve the containers in the Bunded Chemical Stores

When a large quantity of chemicals is stored in IBC’s, drums or other containers, it is always advisable to store them in a bunded chemical store. This will prevent the fast-spreading of leaks and restrict damaging the other container units. It will not allow the spills to reach the ground.

5. On-site containment barriers control spills

You should install containment barriers to control a spill to a particular area of the premise. This will prevent the spillage from spreading to other areas.

Both, manual and automatic containment barriers are available. You can choose according to your need. The automatic barriers are better as they get immediately activated when they sense leak or fire and control the spread.
