Spill Response Procedure: Step-by-Step Guide for UK Workplaces
Every UK workplace that stores or handles hazardous substances must have a documented spill response procedure. Under the Control of Substances Hazardous to Health (COSHH) Regulations 2002, employers are legally required to assess the risks of chemical substances and put in place adequate emergency controls — including procedures for dealing with accidental releases.
Failing to respond to a spill correctly can result in serious injury, environmental damage, regulatory prosecution, and significant reputational harm. This guide walks you through a compliant, effective step-by-step spill response procedure suitable for UK industrial and commercial workplaces.
Why a Written Spill Response Procedure Matters
The Health and Safety at Work etc. Act 1974 places a general duty on employers to ensure the safety of employees and others who may be affected by their work activities. The Environmental Protection Act 1990 and Water Resources Act 1991 add further obligations to prevent pollution of land, waterways, and sewers. A clear, practised spill response procedure is central to meeting all of these duties.
Step-by-Step Spill Response Procedure
| Step | Action | Responsible |
|---|---|---|
| 1 | Raise the alarm — alert colleagues in the immediate area and notify your spill response team or supervisor | First responder |
| 2 | Identify the substance — check the Safety Data Sheet (SDS) for hazard information, PPE requirements, and first aid measures | First responder / supervisor |
| 3 | Don appropriate PPE — at minimum, chemical-resistant gloves, safety glasses, and appropriate footwear | Response team |
| 4 | Contain the spill — use spill kits, drain covers, or spill berms to prevent spread | Response team |
| 5 | Absorb and clean up — apply appropriate absorbent materials and collect contaminated waste | Response team |
| 6 | Dispose of waste correctly — package waste in sealed, labelled containers and arrange for licensed hazardous waste disposal | Supervisor / waste contractor |
| 7 | Decontaminate the area — clean the spill zone and inspect for residual contamination | Response team |
| 8 | Report and record — complete an incident report and review your COSHH risk assessment if necessary | Manager / H&S officer |
Essential Spill Response Equipment
Having the right equipment immediately accessible is critical. Your spill response kit should be:
- Located within easy reach of chemical storage and handling areas
- Clearly labelled and colour-coded by spill type (oil, chemical, or universal)
- Regularly inspected and replenished after use
- Appropriate for the volume of substances on site

Training and Competency
Under COSHH and the Management of Health and Safety at Work Regulations 1999, employers must provide adequate information, instruction, and training to employees who may be involved in spill response. At minimum, this should include:
- How to identify chemical hazards using SDS and GHS labels
- Correct selection and use of PPE
- Practical spill containment and clean-up techniques
- Procedures for notifying the Environment Agency where pollution risk exists
Environmental Obligations
If a spill reaches a drain or watercourse, you may have a legal obligation to notify the Environment Agency (or NRW in Wales, SEPA in Scotland). Failure to report an environmental incident can result in prosecution under the Environmental Permitting Regulations 2016. Always err on the side of reporting — prompt notification demonstrates responsible management and can significantly reduce penalties.
Review and Continuous Improvement
Every spill incident — however minor — should trigger a review of your response procedure. Ask: Was the right equipment available? Did all staff know what to do? Could the spill have been prevented? Update your COSHH risk assessment accordingly and record all actions taken.
