The Irish Legal Framework for Chemical Safety in Cleaning
If you search for “COSHH cleaning Ireland,” you will find a lot of UK-focused content. COSHH (Control of Substances Hazardous to Health) is a UK regulation and does not apply in Ireland. Ireland has its own chemical safety legislation that implements the same EU directives but through different statutory instruments.
The key Irish legislation for chemical safety in cleaning companies:
Primary Legislation
| Legislation | Reference | What It Covers |
|---|---|---|
| Safety, Health and Welfare at Work Act 2005 | No. 10 of 2005 | Overarching duty to ensure employee safety. Requires hazard identification, risk assessment, and Safety Statement. Sections 8, 19, 20 are directly relevant. |
| Safety, Health and Welfare at Work (Chemical Agents) Regulations 2001 | S.I. No. 619 of 2001 | Implements EU Directive 98/24/EC. Requires chemical risk assessment, exposure monitoring, health surveillance, and control measures for all workplaces using chemical agents. |
| Safety, Health and Welfare at Work (Chemical Agents) (Amendment) Regulations 2015 | S.I. No. 623 of 2015 | Updates occupational exposure limit values (OELVs) and aligns with latest EU scientific committee recommendations. |
| European Communities (Classification, Labelling, Packaging and Notification of Dangerous Substances) Regulations | CLP Regulation (EC) No 1272/2008 | EU-wide classification and labelling system using GHS pictograms, signal words, and hazard statements. All cleaning chemicals sold in Ireland must comply. |
| REACH Regulation | (EC) No 1907/2006 | Registration, Evaluation, Authorisation and Restriction of Chemicals. Requires Safety Data Sheets in 16-section format for all chemical products. |
Common Cleaning Chemicals and Their Hazards
Commercial cleaning uses a range of chemical agents, many of which present significant health hazards if not handled correctly. Understanding the specific risks of each chemical category is the foundation of your risk assessment.
Cleaning Chemical Risk Matrix

How to Conduct a Chemical Risk Assessment
The Chemical Agents Regulations 2001 (Regulation 4) require employers to assess the risks from chemical agents at work. For cleaning companies, this means assessing every chemical product you use on every site. Here is the step-by-step process:
Step 1: Chemical Inventory
Create a complete inventory of every chemical product used across all your cleaning contracts. For each product, record:
- Product name and manufacturer
- Chemical composition (from the SDS Section 3)
- CLP classification and GHS pictograms (from SDS Section 2)
- Quantity used per week/month
- Sites where it is used
- Tasks it is used for
- Concentration used (ready-to-use, diluted, or concentrate)
Step 2: Obtain and Review Safety Data Sheets
You must have a current SDS for every product. “Current” means the version issued by the manufacturer when you last purchased the product. SDSs are updated when formulations change or new hazard information becomes available.
SDS Documentation Checklist
| SDS Section | What to Check | Action Required |
|---|---|---|
| Section 1: Identification | Product identifier matches your inventory | Confirm product name and supplier details are correct |
| Section 2: Hazard identification | CLP classification, signal word, pictograms, hazard statements | Record all hazards in your risk assessment; update chemical store labels |
| Section 4: First-aid measures | Actions for inhalation, skin contact, eye contact, ingestion | Ensure first aid kits are stocked appropriately; train staff on product-specific first aid |
| Section 7: Handling and storage | Safe handling precautions, storage conditions, incompatibilities | Check your storage arrangements comply; update SOPs |
| Section 8: Exposure controls / PPE | OELVs, engineering controls, specific PPE requirements | Provide specified PPE; check ventilation requirements for each task |
| Section 10: Stability and reactivity | Conditions to avoid, incompatible materials, hazardous decomposition | Ensure incompatible chemicals are stored separately; include in mixing prohibition training |
| Section 11: Toxicological information | Acute toxicity, skin corrosion, sensitisation, carcinogenicity | Assess whether any products should be substituted with safer alternatives |
| Section 13: Disposal considerations | Waste treatment methods, EU waste codes | Ensure waste disposal complies with EPA requirements |
Step 3: Assess Exposure
For each chemical and each task, assess how workers are exposed:
- Inhalation: spraying products, using volatile chemicals in enclosed spaces, mixing concentrates
- Skin contact: splashes during pouring or mixing, prolonged contact through gloves that are not chemical-resistant, skin contact during mopping or wiping
- Eye contact: splashes during pouring, spray drift, touching eyes with contaminated gloves
- Ingestion: eating or drinking in chemical storage areas, chemicals in unlabelled containers mistaken for drinks
Consider the duration of exposure (a quick wipe vs. 4 hours of continuous spraying), the concentration (diluted ready-to-use vs. concentrate), and the ventilation (well-ventilated open-plan office vs. enclosed toilet cubicle).
Step 4: Identify Control Measures
The Chemical Agents Regulations require you to apply the hierarchy of controls:
- Elimination: can you remove the chemical entirely? (e.g., replace chemical cleaning with steam cleaning)
- Substitution: can you use a less hazardous product? (e.g., replace solvent-based degreaser with water-based)
- Engineering controls: can you reduce exposure through ventilation, enclosed systems, or dilution systems?
- Administrative controls: training, SOPs, time limits on exposure, job rotation
- PPE: gloves, eye protection, respiratory protection — always the last line of defence
PPE Requirements for Cleaning Chemicals
Personal Protective Equipment is the last line of defence against chemical exposure, but it is the most visible and most frequently inspected control measure. Under the Safety, Health and Welfare at Work (General Application) Regulations 2007 (Part 2, Chapter 3), employers must provide suitable PPE free of charge and ensure it is properly used.
PPE Requirements by Chemical Type
| Chemical Category | Gloves | Eye Protection | Respiratory Protection | Protective Clothing |
|---|---|---|---|---|
| Neutral detergents (pH 6–8) | Nitrile or latex gloves (EN 374) | Not required for normal use | Not required | Standard uniform |
| Bleach / sodium hypochlorite | Nitrile gloves, min 0.3mm thickness (EN 374) | Safety goggles when mixing concentrate | FFP2 mask in enclosed spaces or when mixing | Apron when handling concentrate |
| Acidic descalers (HCl, phosphoric acid) | Chemical-resistant gloves (nitrile or neoprene, EN 374-3) | Safety goggles or face shield | FFP2 minimum; half-face respirator with acid gas filter (A1) for concentrate | Chemical-resistant apron, long sleeves |
| Caustic products (NaOH, oven cleaners) | Chemical-resistant gloves (nitrile or neoprene, min 0.5mm) | Safety goggles or face shield | FFP2 mask when spraying | Chemical-resistant apron, long sleeves |
| Alcohol-based sanitisers (IPA >60%) | Nitrile gloves | Safety glasses if spraying | FFP2 in poorly ventilated spaces | Standard uniform (no open flame) |
| Peracetic acid | Chemical-resistant gloves (butyl rubber or neoprene) | Full-face shield | Half-face respirator with combination filter (ABEK-P3) | Chemical-resistant suit for high concentrations |
| Quaternary ammonium sprays | Nitrile gloves (EN 374) | Safety glasses when spraying above shoulder height | FFP2 mask when spraying in enclosed areas | Standard uniform |
Chemical Storage and Segregation
Improper chemical storage is one of the most common findings in HSA inspections of cleaning companies. The rules are straightforward but frequently breached:
- Original containers only: never decant chemicals into unmarked bottles, food containers, or drink bottles. This is the single biggest cause of accidental chemical ingestion in the workplace.
- Locked storage: cleaning chemicals must be stored in a locked area, inaccessible to unauthorised persons, particularly in schools, healthcare facilities, and public buildings.
- Segregation: acids and bleach must never be stored together. Flammable products (IPA, solvents) must be stored in a fire-resistant cabinet away from ignition sources. Oxidisers (hydrogen peroxide, peracetic acid) must be separated from organic materials.
- Ventilation: chemical stores must be ventilated, either naturally or mechanically. An enclosed, unventilated cupboard concentrating fumes is a breach.
- Inventory: a current inventory of all chemicals in the store must be posted on or near the door.
- Spill kits: appropriate spill containment materials must be immediately available near the chemical store.
- Temperature: some products have storage temperature limits (check SDS Section 7). Chemical stores in direct sunlight or near heating systems may breach these limits.
Chemical Storage Segregation Matrix
| Acids | Alkalis/Bleach | Flammables | Oxidisers | Neutral Detergents | |
|---|---|---|---|---|---|
| Acids | OK | SEPARATE | SEPARATE | SEPARATE | OK |
| Alkalis/Bleach | SEPARATE | OK | CAUTION | CAUTION | OK |
| Flammables | SEPARATE | CAUTION | OK (fire cabinet) | SEPARATE | OK |
| Oxidisers | SEPARATE | CAUTION | SEPARATE | OK | OK |
| Neutral Detergents | OK | OK | OK | OK | OK |
Dangerous Chemical Mixing: The Critical Risk
Accidental or deliberate mixing of incompatible cleaning chemicals is the single most dangerous chemical hazard in commercial cleaning. It has caused deaths in Ireland and internationally. Your chemical risk assessment must include a specific mixing prohibition with the following dangerous combinations clearly communicated to all staff:
- Bleach + acid (descaler, limescale remover, toilet cleaner): produces chlorine gas. Toxic. Can be fatal in enclosed spaces like toilets. This is the most common dangerous mixing scenario in cleaning.
- Bleach + ammonia (some glass cleaners, multi-surface products): produces chloramine vapours. Toxic. Causes severe respiratory irritation and potential lung damage.
- Bleach + hydrogen peroxide: violent exothermic reaction. Can cause explosion risk in confined containers.
- Acid + alkali (caustic): exothermic neutralisation reaction. Splashing risk. Burns.
- Different brands of the same product type: can have different pH or incompatible surfactants, leading to unexpected reactions, gas release, or product degradation.
Exposure Monitoring and Health Surveillance
Regulation 5 of the Chemical Agents Regulations 2001 requires exposure monitoring where the risk assessment identifies a significant risk of exposure. For cleaning companies, this is most relevant when:
- Workers regularly use products containing respiratory sensitisers (some quaternary ammonium compounds, glutaraldehyde in healthcare settings)
- Workers are exposed to chlorine-based products in poorly ventilated areas
- Workers handle concentrate chemicals daily
- Workers report symptoms (skin irritation, breathing difficulty, headaches)
Health surveillance may include pre-employment health questionnaires, periodic occupational health reviews, skin checks for dermatitis, and lung function testing (spirometry) for workers exposed to respiratory sensitisers.
Emergency Procedures for Chemical Incidents
Your chemical risk assessment must include documented emergency procedures for chemical incidents. Every cleaning operative must know what to do in an emergency.
- Skin contact: remove contaminated clothing. Wash affected area with plenty of water for at least 20 minutes. Do not use neutralising agents. Seek medical attention if burns develop or the chemical is corrosive.
- Eye contact: flush eyes with clean water for at least 20 minutes, holding eyelids open. Do not rub. Seek immediate medical attention for any corrosive chemical splash. If an emergency eyewash station is available, use it.
- Inhalation: move to fresh air immediately. If the person is not breathing, call 112 and begin CPR. If breathing but experiencing symptoms (coughing, wheezing, chest tightness), seek medical attention.
- Chemical spill: ventilate the area. Use the appropriate spill kit (absorbent granules for liquids, not sawdust for oxidisers). Wear PPE. Contain the spill. Do not wash down the drain without checking SDS Section 13 for disposal requirements.
- Accidental mixing: evacuate the area immediately. Ventilate if possible (open windows and doors from outside the room). Do not attempt to clean up until fumes have cleared. Call 112 if anyone is showing symptoms. Report to your HSA-registered emergency contact.
Substitution: Reducing Chemical Hazards
The hierarchy of controls requires you to consider substitution before relying on PPE. In practice, many cleaning companies can significantly reduce their chemical risk profile by:
- Switching to ready-to-use dilutions: eliminates the risks of mixing concentrates (splashing, incorrect dilution, contact with concentrate). Concentrated products are cheaper per litre but the risk reduction from pre-diluted products often justifies the cost difference.
- Using microfibre technology: high-quality microfibre cloths and mops can achieve effective cleaning with water alone or with much lower chemical concentrations. This is particularly effective for routine daily cleaning.
- Steam cleaning: eliminates chemicals entirely for many tasks. Steam cleaners achieve thermal disinfection without chemical agents. Effective for hard floors, toilets, kitchen areas, and high-touch surfaces.
- Replacing solvent-based products with water-based: water-based degreasers and cleaners have significantly lower inhalation and fire risks than solvent-based alternatives.
- Eliminating unnecessary products: many cleaning operations use more product types than needed. A rationalised chemical list of 6–8 products can cover all routine commercial cleaning tasks, reducing training burden and storage complexity.
HSA Inspection Expectations
When the HSA inspects a cleaning company or a site where your cleaning operatives work, chemical safety is one of the most common areas of focus. The most frequent findings are:
- Missing or outdated Safety Data Sheets
- No documented chemical risk assessment
- Chemicals decanted into unlabelled containers
- Inadequate or missing PPE
- No evidence of chemical safety training
- Improper chemical storage (acids next to bleach, unlocked storage, no ventilation)
- No spill kit or expired spill kit materials
- No emergency procedure for chemical incidents
To be inspection-ready at all times, maintain a “chemical safety file” for each site containing: chemical inventory, current SDSs for all products, the chemical risk assessment, PPE issue records, training records, and spill kit inspection log.
Frequently Asked Questions
What is the Irish equivalent of COSHH for cleaning companies?
COSHH is a UK regulation and does not apply in Ireland. The Irish equivalent is the Safety, Health and Welfare at Work (Chemical Agents) Regulations 2001 (S.I. No. 619 of 2001), implementing EU Directive 98/24/EC. The requirements are broadly similar to COSHH but reference Irish legislation, the HSA, and EU classification systems.
Do cleaning companies in Ireland need chemical risk assessments?
Yes. Under the Chemical Agents Regulations 2001, every employer using chemical agents at work must carry out a risk assessment. Cleaning companies use chemicals daily — all fall within scope. The assessment must identify chemicals, assess exposure risks, and specify control measures. It must be documented in your Safety Statement.
What Safety Data Sheet information must cleaning companies keep?
You must have a current SDS (16-section format per REACH Regulation) for every chemical product used on every site. SDSs must be readily accessible to workers who handle the chemicals — kept on-site, not just filed in head office. Key sections: hazard identification (2), first-aid (4), handling/storage (7), PPE requirements (8).
What PPE is required for cleaning chemicals in Ireland?
Minimum for all chemical handling: nitrile gloves (EN 374). For bleach or corrosive products: goggles when mixing, FFP2 mask in enclosed spaces, apron for concentrates. For acid-based products: goggles or face shield, acid gas respirator for concentrates. Always check SDS Section 8 for product-specific requirements.
Can cleaning companies mix different cleaning chemicals?
No. Mixing is one of the most dangerous practices in commercial cleaning. Bleach mixed with acids produces chlorine gas, which can be fatal. Bleach mixed with ammonia produces toxic chloramine vapours. Your risk assessment must include a strict mixing prohibition and staff must be trained on the specific dangers.
How should cleaning chemicals be stored on client sites?
In a locked, ventilated area. Original labelled containers only — never decant into unmarked bottles. Acids separated from bleach. Flammables in fire-resistant storage. Oxidisers away from organic materials. Chemical inventory posted on the door. Spill kit available nearby. Temperature limits per SDS Section 7.
What happens if the HSA finds chemical safety failures?
The HSA can issue Improvement Notices (fix within a deadline) or Prohibition Notices (stop immediately). Common findings: missing SDSs, no risk assessment, unlabelled containers, inadequate PPE, no training records, improper storage. Serious breaches lead to prosecution with fines up to €3 million under the 2005 Act.
Do cleaning operatives need chemical safety training?
Yes. Regulation 10 of the Chemical Agents Regulations 2001 requires information, instruction and training for all workers handling chemicals. Training must cover: GHS pictograms, safe handling, PPE use, SDS interpretation, first-aid for chemical exposure, spill response, and storage. Training at induction, when new chemicals are introduced, and refreshed annually. All training documented.
