How to Conduct a COSHH Assessment for Your Hospitality Business

Practical guide to COSHH assessments in UK hospitality. Learn how to identify hazardous substances, obtain safety data sheets, assess risks, and implement controls.

Estimated time: 2 hours

COSHH (Control of Substances Hazardous to Health) assessments are a legal requirement under the COSHH Regulations 2002 for any workplace where employees may be exposed to hazardous substances. In hospitality, this covers a wide range of products: kitchen degreasers, oven cleaners, sanitisers, descalers, glass wash chemicals, drain unblockers, and pest control products, among others.

Many hospitality operators underestimate their COSHH obligations, assuming it only applies to factories or laboratories. In reality, commercial kitchens use some seriously potent chemicals daily, and incorrect handling causes chemical burns, respiratory issues, and skin conditions that account for a significant number of workplace injuries in the sector. An EHO inspector will check your COSHH arrangements, and your employer's liability insurance depends on proper risk management.

This guide walks you through conducting a thorough COSHH assessment, from identifying every hazardous substance in your premises to establishing control measures and keeping your assessments current.

7 steps to complete

1

Identify all hazardous substances in your premises

Conduct a full inventory of every chemical product used in your business, including cleaning products, sanitisers, degreasers, oven cleaners, descalers, drain treatments, pest control products, dishwasher and glasswasher chemicals, hand soaps, and any other substances with hazard warnings. Check everywhere: kitchen, bar, toilets, store rooms, and outdoor areas. Do not forget substances that might be brought on-site by contractors (such as pest control technicians or deep-cleaning teams).

2

Obtain safety data sheets for every product

Request a Safety Data Sheet (SDS) from the manufacturer or supplier for every hazardous substance you have identified. By law, suppliers must provide an SDS for any product classified as hazardous. The SDS contains 16 sections covering identification, hazards, composition, first aid measures, handling and storage requirements, exposure controls, and disposal instructions. Store all SDS documents in a dedicated, accessible folder — staff must be able to find them in an emergency.

3

Assess the exposure risks for each substance

For each hazardous substance, evaluate who is exposed, how they are exposed (inhalation, skin contact, ingestion, eye contact), how often and for how long, and the severity of potential harm. Consider the specific hazard classifications on the product label (corrosive, irritant, harmful, toxic) and the information in the SDS. A descaler used once a week by a trained staff member presents a different risk level than an oven cleaner used daily by multiple staff members.

4

Decide on appropriate control measures

Apply the hierarchy of controls: first consider whether you can eliminate the hazard (switch to a less hazardous product), then reduce exposure (use measured doses, limit contact time), then isolate the hazard (store chemicals in locked, ventilated cupboards away from food), then implement administrative controls (written procedures, restricted access), and finally provide personal protective equipment (gloves, eye protection, aprons). PPE should be the last resort, not the first. Ensure the control measures are practical for a busy kitchen environment.

5

Record your COSHH assessment in writing

Document your assessment for each substance, including the product name, hazard classification, who is at risk and how, the control measures in place, emergency first aid procedures, and storage and disposal requirements. You can use a standardised COSHH assessment form or template. The assessment must be specific to your workplace — a generic form downloaded from the internet with no adaptation to your operation is not sufficient.

6

Train staff on safe handling and emergency procedures

Every member of staff who uses or may encounter hazardous substances must receive COSHH training covering: which products are hazardous, how to read product labels and hazard symbols, correct dilution rates and application methods, required PPE for each product, what to do in case of accidental exposure or spillage, and where to find SDS documents. Training must be practical and product-specific — showing someone how to dilute the concentrated sanitiser they actually use is more effective than a lecture on hazard categories.

7

Review assessments regularly and after any changes

Review your COSHH assessments at least annually, or immediately when you introduce a new product, change suppliers, alter your cleaning procedures, receive new information about a product's hazards, or after any incident involving a hazardous substance. Remove SDS documents for products you no longer use and add sheets for new products. Keep records of all reviews to demonstrate ongoing compliance to inspectors.

Tips for success

Switch to colour-coded, pre-dosed chemical sachets or trigger sprays wherever possible. These reduce the risk of incorrect dilution and chemical splashes compared to pouring from large containers.
Store COSHH assessments and SDS documents digitally as well as in a physical folder. In an emergency, being able to pull up a safety data sheet on a phone is faster than searching through a filing cabinet.
Add COSHH checks to your cleaning schedules so that chemical stock levels and PPE condition are reviewed routinely rather than only when something goes wrong.
Never decant chemicals into unlabelled containers. If you must transfer a product to a smaller container, label it immediately with the product name, hazard warnings, and dilution rate. Unlabelled containers are a prosecution risk.
When comparing cleaning products, consider the total cost including PPE requirements. A cheaper but more corrosive product may cost more when you factor in the protective equipment needed.

Common mistakes to avoid

Storing chemicals in the same area as food or food equipment
COSHH regulations require that hazardous substances are stored separately from food, food packaging, and food contact surfaces. Designate a locked, ventilated storage area specifically for chemicals, ideally with a spill containment tray.
Not having safety data sheets available on-site
In an emergency (chemical splash, accidental ingestion), you need immediate access to the relevant SDS. Keeping SDS documents in an office that is locked at weekends is not acceptable. Maintain a folder in an accessible location that all staff know about, and ideally keep digital copies on a shared device as backup.
Using higher concentrations of chemicals than recommended
Using more chemical than the recommended dilution rate does not clean better — it increases chemical hazard, can damage surfaces, may leave residues that contaminate food, and wastes money. Always follow the manufacturer's dilution instructions and train staff on correct measurement methods.
Treating COSHH as a one-off paperwork exercise
A COSHH assessment that was completed three years ago for products you no longer use has no value. COSHH is a living system that must reflect your current products, procedures, and premises. Build review dates into your calendar and update assessments whenever products change.

Frequently asked questions

Is a COSHH assessment a legal requirement?

Yes. Under the Control of Substances Hazardous to Health Regulations 2002, every employer must assess the risks from hazardous substances in the workplace and implement appropriate controls. This applies to all businesses, including hospitality. Failure to conduct COSHH assessments is a criminal offence enforceable by the Health and Safety Executive (HSE) and local authority inspectors.

What counts as a hazardous substance in a kitchen?

Any product with a hazard symbol on its label is covered by COSHH. In hospitality, this commonly includes oven cleaners, degreasers, sanitisers, bleach, descalers, drain cleaners, dishwasher and glasswasher chemicals, carpet cleaners, and pest control products. Even some "eco-friendly" or "natural" products may carry hazard warnings. If in doubt, check the product label for GHS (Globally Harmonised System) hazard pictograms.

How often should I review my COSHH assessments?

Review assessments at least annually as a minimum. You must also review whenever you change products or suppliers, introduce new cleaning procedures, receive updated safety information from a manufacturer, when an incident or near-miss occurs, or when staff raise concerns. Practical triggers like switching cleaning supplier should automatically prompt a COSHH review.

Do I need to assess substances used by contractors on my premises?

You are responsible for the health and safety of everyone on your premises, including contractors. Request copies of COSHH assessments and SDS documents from any contractors who bring hazardous substances onto your premises (such as pest control companies or specialist deep-cleaning firms). Check that their products and methods do not create risks for your staff or food safety.
