Chemical spill control
Chemical spill control should begin with the safety data sheet, COSHH assessment and compatibility of the absorbent, PPE and container. The safest approach is to plan before a release happens, then keep chemical spill kits and containment close to the chemical risk.
What problem are you trying to solve?
- What should we do before buying a chemical spill kit?
Identify acids, alkalis, solvents, oxidisers and other hazardous substances, then check the safety data sheet for incompatible materials and emergency measures. - Can one absorbent handle every chemical?
No. Chemical compatibility matters, especially for aggressive, reactive or unknown liquids. Use chemical absorbents and escalate where the spill is outside trained competence. - What documents should be available?
Keep COSHH assessments, safety data sheets, spill response instructions, inspection records and waste disposal notes accessible to staff.
How to choose the right spill control approach
| Site problem | Best practical response | SERPRO link |
|---|---|---|
| Acids, alkalis or hazardous liquid handling | Use chemical spill kits and compatible absorbents. | Chemical Spill Kits |
| Chemical drums or IBCs in storage | Use bunding or sump containment designed for the stored volume. | Spill Containment |
| Laboratory or small-container chemical handling | Use smaller response kits, trays and absorbents close to benches or stores. | Spill Control Resources |
| Unknown liquid or high-risk reaction | Isolate the area and follow site emergency procedures before clean-up. | Spill Management |
Practical next steps
- Review the COSHH assessment and safety data sheet before selecting absorbents.
- Separate chemical spill response from oil-only and general-purpose spill response.
- Store chemical spill kits where chemicals are received, decanted, dispensed or used.
- Train staff on isolation, PPE, escalation, clean-up and disposal limits.
- Record every chemical spill so repeat causes can be removed rather than repeatedly cleaned up.
