Safe, compliant storage is the foundation of effective spill control. If you store oils, chemicals, fuels, coolants, paints, cleaning fluids or other hazardous liquids on site, the right storage solutions reduce leaks, prevent pollution, improve housekeeping, and support UK environmental compliance. This page answers the most common storage questions we see in UK industry and provides practical, site-ready solutions.
Question: What do we mean by storage solutions in spill management?
Solution: In spill management, "storage solutions" are products and practices that keep liquids contained, organised, clearly identified and protected from accidental release. The essentials include bunded storage, drip control, segregation, labelling and access control. For MRO chemical management, good storage also supports better stock rotation, reduces waste, and makes routine inspections faster and more reliable.
Question: How do we stop small leaks becoming a major spill?
Solution: Use secondary containment at the point of storage and decanting. Most spills start as minor drips at valves, pumps, taps, IBC outlets, drum bungs and transfer points. The practical fix is to store containers on drip trays or inside bunded systems so any leak is captured immediately, not after it reaches the floor or a drain. For higher-risk operations, add a defined transfer area with spill kits and drain protection nearby.
Question: Do we need bunded storage for drums and IBCs?
Solution: In most industrial settings, yes. Bunding (secondary containment) is widely regarded as best practice for environmental protection and is commonly expected by insurers, auditors and site EHS teams. Bunded solutions help you:
- Contain leaks from drums, IBCs and containers before they reach drains or soil
- Segregate incompatible chemicals to reduce reaction risk
- Support robust housekeeping and inspection routines
- Demonstrate practical control measures for environmental compliance
Typical solutions include bunded pallets, bunded trays, bunded sheds and bunded cabinets, chosen to suit the chemical type, storage volume, and whether storage is indoors or outdoors.
Question: What storage solution is best for MRO chemicals and maintenance fluids?
Solution: For MRO (maintenance, repair and operations) chemicals, aim for a system that supports control as well as containment. A common, effective setup is:
- Day-to-day working stock stored in a designated chemical cabinet or bunded cupboard close to the point of use
- Bulk stock kept in a bunded store area (or bunded outdoor store where appropriate) to reduce clutter on the shop floor
- Decanting zone protected with bunding and drip trays to capture inevitable drips
- Spill response supported by correctly selected spill kits and clear instructions
This approach reduces ad-hoc storage, supports FIFO stock rotation, and makes it easier to track usage and waste. For background on improving site-wide chemical control, see the Serpro article on MRO chemical management: https://www.serpro.co.uk/blog/mro-chemical-management.
Question: How do we protect drains while storing and handling liquids?
Solution: Treat drains as the critical pathway to pollution incidents. Storage solutions reduce spill likelihood, but you also need a plan for worst-case events such as a forklift puncture, overfill, or a failed tap. Use drain protection products to help block or seal drains quickly, especially in yards, loading bays, and wash-down areas. Place drain protection close to risk points and train staff to deploy it immediately before using absorbents.
Question: How do we choose between a drip tray, a bund, and a spill pallet?
Solution: Match the containment to the risk, volume and handling method:
- Drip trays: Best for small containers, minor drips, and under taps/valves. Ideal at workstations and under decanting points.
- Bunded pallets: Suitable for drums and IBCs where you want robust secondary containment and easier forklift handling.
- Bunded trays/floors: Good for awkward layouts, multiple small containers, or where you need a defined containment footprint.
If the storage area is exposed to rain, ensure the containment plan accounts for water ingress and inspection routines. Outdoor storage should avoid uncontrolled filling of bunds with rainwater.
Question: What about flammables, solvents, and aerosols?
Solution: Flammable liquids and aerosols require additional controls for fire risk and access. Use appropriate storage cabinets and keep stock levels sensible. Separate ignition sources, control quantities at point of use, and keep spill response equipment nearby. Where solvents are used frequently, provide drip trays and fast-response absorbents at decanting points to reduce vapour exposure and slip risk.
Question: How can storage solutions support UK environmental compliance?
Solution: Good storage demonstrates active prevention of pollution, which is central to UK environmental expectations for industrial sites. Practical measures include secondary containment, clear labelling, segregation of incompatible substances, and a documented spill response plan. This supports consistent audit performance and helps reduce the chance of a reportable incident.

Question: What does a good storage layout look like in real sites?
Solution: Here are proven examples that improve spill control and operational efficiency:
- Engineering workshop: Small packs of oils and cleaners stored in a dedicated cupboard; decanting carried out over drip trays; a general-purpose spill kit within 10 seconds reach.
- Warehouse and goods-in: Drums and IBCs stored on bunded pallets; loading bay equipped with drain covers and a spill kit designed for oils and fuels; clear signage for emergency steps.
- Facilities and plant room: Coolants, dosing chemicals and maintenance fluids stored within bunded trays; inspection tags used to verify weekly checks; empty containers quarantined to avoid residual drips.
Across all sites, the goal is the same: reduce the chance of release, contain what you cannot prevent, and keep response equipment accessible.
Question: How do we inspect and maintain storage solutions?
Solution: Put routine inspection into your maintenance rhythm. Check for cracks, deformation, blocked outlets, standing liquids in bunds, and damaged containers. Confirm labels are intact and chemicals are stored with compatible products. Ensure spill kits are complete and that absorbents have not been used or contaminated. A short weekly check is usually enough to catch issues before they become incidents.
Question: What spill response products should we keep near stored liquids?
Solution: Storage controls reduce incidents, but you still need fast response capability. Position spill response around storage and transfer points:
- Absorbents for oils, coolants and general liquids
- Spill kits selected for the liquids on site (oil-only, chemical, or maintenance/general purpose)
- Drain protection where liquids could reach surface water drains
For higher-risk liquids, add clear work instructions covering isolation of the source, drain protection first, then containment and clean-up.
Question: How do we select the right storage solution quickly?
Solution: Use a simple selection checklist:
- What liquid is it (oil, chemical, fuel, water-based coolant, solvent)?
- What is the container type (small pack, drum, IBC) and maximum volume stored?
- Where is it stored (indoors, outdoors, near drains, near heat sources, near traffic routes)?
- How is it handled (forklift, hand moved, decanted, pumped)?
- What is the realistic worst-case spill scenario?
If you can answer those questions, you can choose between drip trays, bunded pallets, bunded stores, cabinets and supporting spill response equipment with confidence.
Next steps
Review your current chemical and oil storage areas, identify where leaks could reach drains, and upgrade containment at the highest-risk points first. Then standardise your approach across site so every storage area follows the same spill control rules.
