Spill trays must be impermeable to the stored liquids and must consist of non-combustible building materials.
The material from which a spill tray is made from, must be suitable for the stored liquids. For the storage of water-polluting and flammable substances such as oils and lacquers, steel spill trays should be used. Available in a galvanized or lacquered version.
For storage of aggressive chemicals such as acids and alkali,stainless steel or plastic spill trays should be used.
In order to be able to select the suitable material for the spill pallet, it is recommended to look into the safety data sheets of the substances to be stored. There you will find all relevant information about storage and transport.
Our media resistance list also gives you useful information on suitable materials for a wide variety of storage media. The corrosion resistance of the spill pallet materials used as well as their compatibility with the stored substances must be verifiable.
For many chemical substances, spill pallets made of steel (1.0038) can be used. For corrosive substances such as acids and alkali, spill pallets made of polyethylene or stainless steel are required.
Depending on the intended use, spill trays and pallets must be able to cope with different requirements. Spill pallets with integrated forklift pockets are ideal for safe internal transport with a forklift truck.
In addition, it is important to consider the collection volume of the tray or pallet, and the spill tray should always be thoroughly tested and certified and compliant with all current regulations.
The storage space must be suitable; there must be permanent ventilation, explosion protection and structural fire protection.
A spill tray height of 500 mm must not be exceeded, because then sufficient ventilation is no longer guaranteed. If a higher tray height is required, you can use technical ventilation.
The spill tray should be subjected to an apparent seal test at least once a week. Remove the hazardous substance properly with suitable absorbents and dispose of safely.
Soak up the leak with an absorbent that is suitable for the hazardous substance being stored. Also, make sure the shape of the absorbent matches the leak. Absorbents are available in the three versions: oil, universal and chemical. Find the right absorbent for your needs here.
Get an overview of the test certificates and the manufacturer's warranty. If you notice signs of corrosion, the spill pallet should be disposed of in accordance with the law. To perform a general leak test, you can of course just pour water into the tub to check the seal.
Many spill pallet models have fork pockets so they can easily and safely be transported by forklift from A to B. Individual models are also available on wheels. If a floor spill tray has to be transported, this can be done on a wooden pallet. In any case, care must be taken that the spill tray is not too full that there is a risk of leakage during transport. If you are required to transport the spill pallets outside the workplace and across public roads, legislation for transporting dangerous goods must be taken into account.
