Serpro: spill management questions answered

Serpro supports UK workplaces with practical spill management, spill control and environmental compliance guidance, plus products such as spill kits, drip trays, bunding and drain protection. This page uses a question-and-solution format so you can quickly find what to do when liquids leak, drip, or spill on site.

Q1. What does "spill management" mean in a UK workplace?

Solution: Spill management is the full process of preventing, preparing for, responding to, and documenting liquid releases that could harm people, operations, or the environment. In practical terms, that typically means:

• Prevent leaks with bunded storage, drip control and good housekeeping.
• Prepare with correctly specified spill kits and clear response plans.
• Respond quickly using absorbents, drain covers, and safe disposal methods.
• Prove compliance with training records, inspections, and incident reporting.

For more detail on what good spill management looks like on UK sites, see the Serpro guidance: https://www.serpro.co.uk/blog/spill-management-uk.

Q2. We have spills "sometimes". What is the real risk if we just mop it up?

Solution: Treating spills as minor housekeeping can create repeated hazards and compliance exposure. Common operational risks include:

• Slip and trip incidents from oil, coolant, water and process liquids.
• Equipment downtime when leaks spread into walkways, cable routes or work areas.
• Environmental harm if liquids reach surface water drains or soil.
• Higher cleanup cost when a small leak becomes a wider contamination area.

A spill response that is planned and repeatable is usually faster and safer than improvising with rags and general waste bins.

Q3. What is the first thing we should do when a spill happens?

Solution: Use a simple, consistent sequence that works across most industrial spills:

1. Make safe: isolate ignition sources if flammable, and manage pedestrian traffic.
2. Stop the source: upright a container, close a valve, place a temporary leak seal if appropriate.
3. Protect drains: deploy drain covers, drain blockers, or drain mats before liquids migrate.
4. Contain: use absorbent socks and booms to ring-fence the spill.
5. Recover: apply pads or granular absorbent suited to the liquid type.
6. Dispose: bag and label waste in line with your site waste procedures and the liquid hazard.
7. Record and improve: log the incident, replenish the spill kit, and address root cause.

This approach aligns with the general spill management principles described by Serpro for UK workplaces (citation): https://www.serpro.co.uk/blog/spill-management-uk.

Q4. Which spill kit do we need: oil-only, chemical, or general purpose?

Solution: Select spill kits by the liquid type, the volume risk, and where the spill might travel:

• Oil-only spill kits: for hydrocarbons such as diesel, lubricating oils, and fuel. Often preferred outdoors because oil-only absorbents can repel water.
• Chemical spill kits: for aggressive or unknown chemicals (acids, alkalis, solvents). These kits typically include PPE guidance and chemical-compatible absorbents.
• General purpose spill kits: for water-based liquids like coolants, glycols, and many process fluids where chemical resistance is not the primary requirement.

Site tip: if you store multiple liquid classes, you may need more than one spill kit placed at the point of risk (for example, one oil kit in the yard refuelling area, and a chemical kit near dosing or IBC decant points).

Q5. How do we size spill kits and spill control equipment properly?

Solution: Size your spill response to your realistic worst-case scenario, not your average leak. A practical way to scope this is:

• Identify the largest single container you handle in each area (drum, IBC, mobile bowser).
• Consider transfer operations where hoses can fail or valves can be left open.
• Factor in surface and drainage: a sloped yard or a nearby drain increases spread risk.
• Decide if you need rapid deployment (for example, forklifts, battery rooms, fuel points, loading bays).

A good spill kit is one that can be deployed in minutes, contains enough booms to protect drains, and has sufficient absorbent capacity to finish the job without leaving residues that continue to spread.

Q6. What is bunding and when should we use it?

Solution: Bunding is secondary containment designed to stop liquids escaping from stored containers. It is used to reduce environmental risk and to support compliant storage practices. Typical bunding solutions include:

• Bunded pallets for drums and IBCs.
• Bunded flooring or containment areas in chemical stores and plant rooms.
• Drip trays under small containers, pumps, and leaking assets to prevent persistent drips becoming slip hazards.

Operational example: a maintenance workshop can reduce repeat spills by placing a drip tray under filter changes and using bunded pallets where oils and lubricants are decanted.

Q7. How do we protect drains during a spill in a yard or loading bay?

Solution: Treat drain protection as a primary objective in your spill response. Consider a layered approach:

• Drain covers or drain mats placed over the drain to block entry.
• Absorbent socks/booms positioned upstream to slow the flow and create a containment ring.
• Spill berms or temporary bunding for repeated transfer points.

Site tip: keep drain protection equipment close to external drains, not only inside a store room, so response time is measured in seconds, not minutes.

Q8. What does compliance look like for spill management in the UK?

Solution: Compliance is achieved by combining suitable equipment with documented, repeatable processes. While requirements vary by site and sector, strong spill management usually includes:

• Risk assessment for liquids stored and handled, including spill pathways to drains.
• Spill response procedure that defines responsibilities, escalation, and disposal routes.
• Training so staff know which spill kit to use and how to protect drains.
• Inspections to check bunding integrity, drip tray use, and spill kit replenishment.
• Incident records to show corrective actions and continuous improvement.

Serpro provides UK spill management guidance and practical steps to improve preparedness (citation): https://www.serpro.co.uk/blog/spill-management-uk.

Q9. What should be in a spill response plan for an industrial site?

Solution: A usable plan is short, specific to the site, and easy to follow under pressure. Include:

• Spill scenarios (fuel spills, coolant leaks, chemical decant spills).
• Spill kit locations and which kit is intended for which area.
• Drain protection points (map key drains and watercourse risks).
• Escalation triggers (spill volume, unknown chemical, ignition risk, drain entry).
• Waste handling (bagging, labelling, storage for collection).
• Restock and review process after every use.

Operational example: a logistics depot can keep a rapid-deployment spill kit on the shunter vehicle, plus a larger fixed spill station at the fuel island.

Q10. Where can we get help choosing spill control products?

Solution: Use Serpro resources to align products with your spill risks and compliance needs. Start with the spill management overview (citation): https://www.serpro.co.uk/blog/spill-management-uk. If you are planning upgrades, focus on a combined approach:

• Spill kits matched to liquids and volumes.
• Drip trays for persistent leak points and routine maintenance.
• Bunding for storage and transfer risk reduction.
• Drain protection for external yards and high-consequence areas.

Next steps

If you want to improve spill control performance quickly, review your highest-risk areas first: external drains, refuelling points, IBC decant locations, and maintenance bays. Then place the right spill kits and drain protection at the point of use, train teams, and set a simple inspection and restock routine.
