Why Chemical Cleaning Activities Need Risk Assessment
Cleaning chemicals are used in almost every workplace, including offices, warehouses, schools, hospitals, hotels, and industrial facilities. While these products help maintain hygiene and cleanliness, they can also introduce workplace hazards if they are not used, stored, or handled safely.
Common risks include skin irritation, eye injuries, harmful fumes, accidental mixing of incompatible chemicals, and spills.
For new HSE learners, chemical cleaning activities provide a practical example of how hazards are identified, risks are assessed, and suitable control measures are selected.
This guide explains what learners should check during a chemical cleaning activity risk assessment using simple workplace examples. It is intended for educational purposes and does not replace workplace-specific procedures or specialist chemical safety advice.
What Should a Chemical Cleaning Risk Assessment Cover?
A chemical cleaning activity risk assessment should consider:
- The cleaning chemical being used
- The task being performed
- Who may be exposed
- The work environment
- Existing control measures
- Additional improvements that may reduce risk
Every workplace is different, so assessments should always reflect the actual products, equipment, and working conditions.
For a complete overview of workplace risk assessments, explore our Risk Assessment Guide.
Common Hazards During Chemical Cleaning
Some common hazards include:
- Skin contact with cleaning chemicals
- Eye exposure from splashes
- Inhaling vapours or fumes
- Slippery floors caused by spills
- Incorrect storage of chemicals
- Mixing incompatible cleaning products
- Poor ventilation during cleaning activities
Recognising these hazards is the first step toward reducing workplace risk.

Further Controls
- Train workers not to mix chemicals unless specifically instructed by the manufacturer.
- Store incompatible products separately.
- Follow product instructions carefully.
Chemical products should always be used according to the manufacturer’s guidance.
Example 4: Chemical Storage
Hazard
Cleaning chemicals stored in unlabelled containers.
Who May Be Harmed?
- Cleaning staff
- Contractors
- Visitors
Possible Risks
- Incorrect product use
- Accidental exposure
- Spills
Existing Controls
- Designated storage area.
Further Controls
- Keep chemicals in clearly labelled containers.
- Remove damaged or unreadable labels.
- Store products securely and according to manufacturer recommendations.
- Carry out regular storage inspections.
Proper labelling reduces the risk of accidental misuse.
Example 5: Cleaning Spill Response
Hazard
Chemical spill during routine cleaning.
Who May Be Harmed?
- Cleaning staff
- Employees walking nearby
Possible Risks
- Slips and falls
- Skin contact
- Environmental contamination
Existing Controls
- Cleaning equipment available.
- Spill reporting procedure.
Further Controls
- Train staff in spill response.
- Restrict access until the area is safe.
- Dispose of contaminated materials appropriately.
- Review the cause of the spill to prevent recurrence.
Prompt action helps minimise the impact of accidental spills.
Applying the Hierarchy of Controls
Chemical cleaning tasks are a good example of how the Hierarchy of Controls can improve workplace safety.
Hazard
Exposure to cleaning chemical vapours.
PPE-Only Approach
- Wear gloves and eye protection.
Stronger Controls
Elimination
- Remove unnecessary chemical cleaning tasks where practical.
Substitution
- Use a less hazardous cleaning product if suitable.
Engineering Controls
- Improve ventilation or local extraction.
Administrative Controls
- Safe work procedures.
- Worker training.
- Clear product labelling.
- Scheduled cleaning during quieter periods.
PPE
- Gloves, eye protection, or other suitable PPE where residual risk remains.
Using several levels of the hierarchy generally provides stronger protection than relying on PPE alone.
For more information, see our Hierarchy of Controls guide.
Why Product Labels Matter
Cleaning product labels provide important information, including:
- Safe handling instructions
- Storage recommendations
- Hazard information
- First aid advice
- Personal protective equipment recommendations
Workers should always read and follow the manufacturer’s instructions before using any cleaning chemical.
Common Mistakes During Chemical Cleaning
Mixing Different Chemicals
Mixing products without following manufacturer guidance may create additional hazards.
Using Chemicals in Poorly Ventilated Areas
Limited airflow may increase exposure to vapours.
Ignoring Product Labels
Skipping manufacturer instructions increases the likelihood of incorrect use.
Relying Only on PPE
Gloves and eye protection are important, but better ventilation, safer products, and improved work methods often provide stronger protection.
Poor Housekeeping
Leaving chemical containers open or allowing spills to remain unattended increases workplace risk.
Questions to Ask During a Chemical Cleaning Risk Assessment
When reviewing cleaning activities, consider:
- What chemical is being used?
- Who may be exposed?
- Is adequate ventilation available?
- Are containers clearly labelled?
- Could a less hazardous product be used?
- Are workers following manufacturer instructions?
- Is suitable PPE available where required?
- Is there a procedure for dealing with spills?
These questions help learners identify practical improvements during workplace assessments.
Why These Examples Matter
The examples in this guide demonstrate how hazard identification, risk evaluation, and control selection apply to everyday cleaning activities.
Rather than copying these examples into workplace documentation, use them to understand the thought process behind an effective chemical cleaning risk assessment.
Each workplace uses different products, equipment, and cleaning methods, so assessments should always reflect actual working conditions.
Building Better Chemical Risk Assessment Skills
Chemical cleaning activities involve a combination of physical, chemical, and organisational hazards.
By identifying specific hazards, reviewing existing controls, selecting stronger control measures, and considering residual risk, HSE learners can produce more practical and effective workplace risk assessments.
If you’re learning how to document workplace hazards, our Risk Assessment Template provides a structured format for recording hazards, controls, responsibilities, and recommended actions.
