Barrel Bunds

About Barrel Bunds

Barrel bunds, also known as spill pallets or drum bunds, are essential containment systems designed to safely store drums, barrels, and intermediate bulk containers (IBCs) whilst preventing hazardous liquids from contaminating the environment. These specialist storage solutions feature a raised platform with an integrated sump that captures any leaks, drips, or spills from the containers stored above, ensuring compliance with stringent UK environmental protection regulations and COSHH requirements. Whether you're managing waste oils in an automotive workshop or storing chemicals on a construction site, barrel bunds provide a legally compliant barrier between hazardous substances and the environment.

Available in robust materials including high-density polyethylene (HDPE) and heavy-duty steel, barrel bunds provide a practical solution for storing oils, chemicals, fuels, and other potentially harmful substances. The sump capacity is carefully engineered to contain at least 110% of the largest drum's volume or 25% of the total stored capacity, whichever is greater, as mandated by the Control of Pollution (Oil Storage) (England) Regulations and Environmental Permitting Regulations across the UK. Tooled-Up.com stocks barrel bunds from trusted manufacturers including Sealey and Draper, offering single and double drum configurations suitable for standard 205-litre drums, as well as polyethylene workflooring systems that can be configured to accommodate multiple containers.

These containment solutions are invaluable for workshops, warehouses, factories, construction sites, and any commercial premises where hazardous substances are stored or handled regularly. With options ranging from lightweight portable polyethylene units to heavy-duty steel constructions, there's a suitable bund for every application, whether you need temporary workfloor storage or a permanent fixed installation for long-term chemical management.

How to Choose the Right Barrel Bunds

Capacity Requirements: Determine how many drums you need to store simultaneously. Single-drum bunds accommodate one 205-litre barrel, whilst larger models can hold two, four, or more containers. Always verify the sump capacity meets the 110% rule for your largest container to ensure legal compliance.

Material Selection: Choose between polyethylene and steel construction based on your storage needs. HDPE bunds from brands like Sealey and Draper offer superior chemical resistance and won't corrode, making them ideal for acids and aggressive chemicals. Steel bunds provide exceptional strength and durability for heavy-duty industrial environments but may require coating for certain chemical applications.

Indoor vs Outdoor Use: For external storage, consider weatherproof models with UV-resistant properties and adequate drainage provisions. Indoor bunds can be lighter and may not require additional weather protection features. Polyethylene workflooring systems are particularly versatile for temporary or mobile applications.

Load Capacity: Calculate the total weight of your filled drums plus containers to ensure the bund's load rating is sufficient. Don't underestimate this – a full 205-litre drum of oil or chemical can easily exceed 200kg, so structural integrity is crucial for safe operation.

Access Requirements: Consider how you'll move drums on and off the bund. Some models feature removable grids or low-profile designs that facilitate drum handling with trolleys or pump trucks. Forklift access may influence your choice of grid spacing and overall design. Ramp accessories are available from Tooled-Up for easier drum loading.

Regulatory Compliance: Ensure your chosen bund meets UK HSE guidelines, Environment Agency requirements, and relevant industry standards. This is particularly important for insurance purposes and avoiding potential fines from environmental health inspections.

Safety Information

Proper use of barrel bunds is essential for workplace safety and environmental protection. Always ensure your bund is positioned on level, stable ground capable of supporting the combined weight of containers, contents, and the bund itself. Regularly inspect the sump area and containment system for cracks, damage, or degradation that could compromise its integrity, particularly after harsh weather or heavy use.

Never exceed the stated load capacity or sump volume, as this could result in structural failure or inadequate spill containment. The sump must be kept clear of debris and any collected liquids should be removed promptly and disposed of according to COSHH regulations and environmental legislation. Allowing liquids to accumulate reduces the effective containment capacity and defeats the purpose of the bund system.

Ensure adequate ventilation when storing volatile substances, and position bunds away from ignition sources, drains, and watercourses. All personnel handling hazardous materials should receive appropriate training and wear suitable PPE including chemical-resistant gloves, safety footwear, and eye protection as required by your risk assessment. Consider the specific hazards of the substances you're storing when selecting protective equipment.

Maintain clear labelling of stored substances and keep Safety Data Sheets readily accessible near the storage area. Implement a regular inspection schedule and document all checks as part of your environmental management procedures. In the event of a significant spill that breaches the bund or threatens to enter drains or watercourses, follow your site's emergency response procedures and notify the Environment Agency immediately if there's any risk of environmental contamination.

Frequently Asked Questions

What size bund do I need for a 205-litre drum?
For a single 205-litre drum, you'll need a bund with a minimum sump capacity of 225 litres (110% of drum capacity) to meet UK regulations. Most single-drum bunds from Sealey and Draper stocked at Tooled-Up are designed specifically to meet this requirement, so check the product specifications to confirm compliance.

Can I use a polyethylene bund outdoors?
Yes, high-density polyethylene bunds are suitable for outdoor use and offer excellent weather resistance without degradation. However, for extended outdoor storage, consider adding a weather cover to prevent rainwater accumulating in the sump (which reduces effective containment capacity) and to protect stored materials from UV exposure and temperature fluctuations.

Do barrel bunds require planning permission or notification?
Whilst the bund itself typically doesn't require planning permission, storing certain quantities of hazardous materials may require notification to the Environment Agency or local authorities. Oil storage installations above 200 litres often require compliance with specific regulations under the Control of Pollution (Oil Storage) Regulations. Check with your local Environmental Health department for guidance specific to your situation and substances.

How do I clean out the sump area?
Regularly inspect and empty the sump using an appropriate pump or absorbent materials designed for the specific liquid collected. Any collected liquids must be disposed of as hazardous waste through a licensed contractor – never pour them down drains or dispose of them with general waste. Never allow the sump to fill beyond its working capacity, as this defeats the purpose of spill containment.

Are steel or plastic bunds better for my workshop?
Both materials have advantages depending on your application. Polyethylene bunds offer superior chemical resistance, lighter weight for portability, and won't corrode, making them ideal for most workshop and industrial applications involving acids or aggressive chemicals. Steel bunds provide maximum strength and durability for heavy-duty environments with very heavy loads but may corrode if used with certain chemicals unless properly coated. Consider your specific storage requirements, the chemicals involved, and whether you need portability when making your choice.
