Construction Site Spill Control: What Should Be in Place Before Work Starts?
Problem: Construction and civil engineering sites change daily. Fuel bowsers, generators, hydraulic plant, temporary stores and drainage routes move as the project develops. The best spill control plan is therefore portable, visible and easy for site teams and subcontractors to understand.
Solution: Build the spill control layout around the liquids used, the places where they are stored or handled, and the route a spill would take if nobody stopped it. This page is designed to help buyers choose suitable SERPRO spill kits, absorbents, drip trays, secondary containment and inspection tools for this sector.
What should this workplace put in place?
- Start with drainage: Identify gullies, ditches, watercourses, soakaways and unmade ground before choosing kit locations. A spill kit too far from the drain is often too late.
- Equip fuel and plant areas: Use oil and fuel spill kits, drip trays under static plant, bowser mats where appropriate and absorbent socks or booms for run-off control.
- Create mobile response points: For large or spread-out sites, use mobile spill kits or localised absorbent stations rather than relying on one store in the site office.
- Check after weather and site changes: Inspect kits after heavy rain, groundwork changes, plant movement and subcontractor changes because risk locations shift.

Practical selection method
Use this simple decision path before ordering. First, identify whether the main risk is oil and fuel, water-based workplace fluids, aggressive chemicals, battery acid, AdBlue, food and drink liquids, or an unknown substance. Secondly, decide whether the spill is most likely at a machine, container, vehicle, store, drain, yard or loading point. Thirdly, choose the correct response method: absorbent pads for flat surface clean-up, socks and booms for containment, drip trays for repeat leaks, bunds for storage, drain protection for escape routes and documented checks for compliance evidence.

Buyer questions answered
What should we buy first?
Start with the spill type, the escape route and the storage area. In most sites this means a suitable spill kit, absorbents at the point of use, drip trays under repeat leaks and drain protection where liquid could leave the area.
Where should the kit be kept?
Keep it where the spill is most likely to happen, not just where stores space is available. Staff should be able to reach it quickly without unlocking several doors or crossing the whole site.
How often should spill equipment be checked?
Check after every use and include it in routine workplace inspections. Replenish pads, socks, disposal bags and instructions immediately so the next incident is not under-equipped.
Next step
For help matching a spill kit, absorbent type, drip tray or containment product to this workplace, contact SERPRO with the liquid type, container size, storage location, drainage risk and the approximate maximum spill volume. That information allows the product choice to be based on the real workplace problem rather than a generic spill kit description.
