Quick answer
Assess cleaning chemicals through the actual task: product, concentration, method, exposure, equipment and people. Use current labels and safety data sheets to select effective prevention and controls before work. Never treat a folder of sheets as the completed assessment or assume a food-safe cleaning purpose makes the product harmless to workers.
Identify the actual product and task
HSE hospitality cleaning guidance describes risks from concentrates, splashes, sprays and unsuitable handling. Record the precise product and how it is stored, diluted, applied, removed and disposed of.
Include oven cleaning, warewashing products, disinfection, descaling and other relevant tasks. The same product can create different exposure when sprayed, manually poured or used in an enclosed area.
Assess exposure and workable controls
| Area | Question |
|---|---|
| Substance | What hazards and product instructions apply at the actual concentration? |
| Exposure | Could skin/eyes, breathing or accidental ingestion be affected? |
| People | Who carries out the work and who else may be exposed? |
| Prevention | Can the task/product/form reduce exposure? |
| Controls | Are dosing, ventilation, methods and suitable protection practical? |
| Failure | What happens with damage, a spill or failed equipment? |
HSENI COSHH guidance makes the separate NI duty and task assessment clear. A supplier sheet contributes evidence but is not the workplace assessment.
Give staff exact usable instructions
Specify product identity, approved preparation and application, relevant protection, ventilation and the safe response to problems. Follow current product instructions; do not invent a universal dilution or contact time. Never mix cleaning products or put them into food/drink containers.
Consider handling of heavy concentrates and opportunities for closed or controlled dosing. Labels, accessible information and suitable storage must remain reliable after decanting.
Investigate a practical control gap
Illustrative example: a cleaner uses an approved product but sprays it near face height in a poorly ventilated space. The assessment needs the actual application and exposure conditions, not only the product’s normal diluted use.
If the approved method cannot be achieved, stop the affected task and obtain competent reassessment. Do not improvise a stronger solution, respiratory device or ventilation modification.
Verify use and review changes
Observe real work, ask staff to explain exceptions and check equipment and protection condition. Update the assessment after formulation, supplier, method, equipment or exposure changes and relevant incidents.
Use the existing cleaning COSHH worked guide and cleaning-schedule guide to coordinate worker protection with food-cleaning effectiveness. A method must meet both purposes; neither proves the other automatically.
Next steps
- Identify the precise product and actual cleaning sequence.
- Assess exposure and choose prevention/controls before work.
- Provide exact instructions, suitable equipment and emergency arrangements.
- Observe use and review relevant changes.
