In the UK, COSHH stands for ‘Control of Substances Hazardous to Health’.
Under the Control of Substances Hazardous to Health Regulations 2002, employers need to either prevent or reduce their workers’ exposure to substances that are hazardous to their health.
What does COSHH Stand for?
In the UK, COSHH stands for ‘Control of Substances Hazardous to Health’ and under the Control of Substances Hazardous to Health Regulations 2002, employers need to either prevent or reduce their workers’ exposure to substances that are hazardous to their health.
COSHH covers most substances that are hazardous to health.
Now that you know the COSHH meaning, it’s very important to be aware that these ‘substances’ can take many forms and include: chemicals, products containing chemicals, fumes, dusts, vapours, mists, nanotechnology.
Do you need a COSHH Assessment Template?
In the UK, ‘COSHH’ is the law that requires employers to control substances that are hazardous to health. You can prevent or reduce workers exposure to hazardous substances by:
- finding out what the health hazards are;
- deciding how to prevent harm to health (risk assessment);
- providing control measures to reduce harm to health;
- making sure they are used;
- keeping all control measures in good working order;
- providing information, instruction and training for employees and others;
- providing monitoring and health surveillance in appropriate cases;
- planning for emergencies.
Do the COSHH Regulations apply?
Most businesses use substances, or products that are mixtures of substances.
Some processes actually create substances! Any of these could potentially cause harm to employees, contractors and other people. Often harmful substances are easily recognised, but there are many that are not so obvious.
Commonly used substances such as paint, bleach or dust from natural materials may also be very harmful to health.
As an employer, it pays to understand the risks related to the use of hazardous substances and the interactions between them.

Most businesses use substances, or products that are mixtures of substances. Some processes create substances. These could cause harm to employees, contractors and other people.
Sometimes substances are easily recognised as harmful. Equally, common household substances such as paint, bleach or dust from natural materials may also be harmful.
In other circumstances, the potential harm caused by a substance or material may not be easily recognised or even understood.
What do the COSHH Regulations 2002 cover?
- chemicals
- products containing chemicals
- fumes
- dusts
- vapours
- mists
- nanotechnology
And that’s not all! The COSHH regulations also cover these…
- gases and asphyxiating gases and
- biological agents (germs). If the packaging has any of the hazard symbols then it is classed as a hazardous substance.
- germs that cause diseases such as leptospirosis or legionnaires disease and germs used in laboratories.
It’s also worth noting the key hazardous materials that the COSHH Regulations do not cover. You may have heard of them before…
- lead
- asbestos or
- radioactive substances
COSHH Assessment | 5 Steps to Assess Risk
You are probably already aware of many risks in your trade or industry. A COSHH assessment concentrates on the hazards and risks from substances in your workplace.
Remember that hazards and risks are not limited to substances labelled as ‘hazardous’.
Here are 5 steps to making a COSHH assessment, beginning by walking around your workplace:
Is there Potential for Exposure to Substances Hazardous to Health?
Examples include processes that emit dust e.g. cutting concrete, fume e.g. soldering, vapour e.g. use of solvents e.g. acetone for degreasing , mist e.g. spray painting or gas e.g. natural gas for heating i.e. gas boiler or gas being used for a production process; and skin contact with liquids, pastes and dusts.
Many hazardous substances have workplace exposure limits (WELs) – these will be listed in the SDS.
Depending on the risk profile of your process, you may need to carry out a quantitative measurement of the exposure.
This is commonly referred to as an ‘industrial hygiene’ assessment.
How are the COSHH Substances Harmful to Health?
Get safety data sheet (SDS or MSDS’s – take a good look through them. You will get the detail on the hazard or COSHH symbols that you will see on the labels, for example.
It will also provide you with recommended protective equipment required and storage advice.
Examples include fume from welding or soldering, mist from metalworking, dust from quarrying, gases from silage.
Look at the HSE web pages for your trade or industry – Your Industry.
Be aware, harmful substances can be created by mixing of chemicals and/or from industrial processes.
What Jobs or Tasks could lead to COSHH Exposure?
Get all of your the existing information that you have from risk assessments, method statements and so on (as well of course as speaking to people on the ground to make sure you’re not missing anything).
Record what control measures you already use – are these sufficient now that you’ve really taken into consideration the risk from the chemicals or substances that you have reviewed?
You may need to get the operators or engineers for the specific process involved to discuss ‘how’ the work is done to get the facts.
Is COSHH Safety a Concern?
It will be highly valuable to also review information held by the business relating to accidents, incidents, near misses and concern reports.
Make sure to cover any direct or suspected ill-health reports that have occurred or been affected by work activities. Hopefully you have records of any low-level first aid events that have happened, those will inform you on what is happening on the ground too.
Examples include minor burns from splashes, nausea or migraine from solvents, coughing or chest pain from dusts/fumes etc.
Record and Review your COSHH Assessment
You may want to keep your COSHH assessments for each substance as a stand alone document and/or link them to the relevant risk assessments or work processes, depending on what way your business operates.
It should be very clear as to which hazardous substances you use, how you use them and how the risk of harm is controlled.
The important thing is to make sure the relevant information is easily accessible and available to those that need it, at all times.
When it comes to control of substances hazardous to health, there’s something that you will really want to look out for – COSHH Symbols. If a substance is in the original container, it should have information relating to the hazardous properties of the chemical.
COSHH Symbols
The latest internationally-recognised hazard pictograms are very similar to those used in the old labelling system. They appear in the shape of a diamond with a distinctive red border and white background.
One or more pictograms might appear on the labelling of a single chemical.
Hazard symbols (as below) alert us to the presence of a hazardous chemical. They help us to understand how the chemicals we are using might cause harm to people or the environment.
Flammable
WHAT DOES IT INDICATE? Extremely flammable gas, Flammable gas, Extremely flammable aerosol, Flammable aerosol, Highly flammable liquid and vapour, Flammable liquid and vapour, Flammable solid EXAMPLES: Lamp oil, petrol, nail polish remover

Gas Under Pressure
WHAT DOES IT INDICATE? Contains gas under pressure; may explode if heated. Contains refrigerated gas; may cause cryogenic burns or injury. EXAMPLES: Gas containers, cylinders, air conditioning unit
Safe COSHH Storage
Careful storage of COSHH is a crucial part of managing them to prevent harm to people or the environment.
When storing hazardous chemicals in your workplace, take the following steps:
1. Read the safety data sheet (SDS) or label carefully, and follow any storage recommendations.
2. Secure the chemicals against unauthorised access or use – use signage where appropriate
4. Do not allow chemicals to be exposed to the sun, excessive heat or sources of ignition
5. Provide adequate ventilation to avoid build up of gases
6. Label shelves and cupboards so that chemicals can be stored in the right place
8. Do not mix incompatible substances e.g. ammonia and bleach
9. Use bunds/spill trays if possible – do not store liquids above solids to avoid contamination in the event of a leak
10. Ensure that all chemicals are clearly and correctly labelled
The purpose of the COSHH assessment process, is to ensure that not only are you aware of the harmful substances, but that you have considered how they will interact with everything else in your activity or process.
Please remember, not all harmful substances will be labelled with the above information. Hazardous substances can be created from otherwise benign materials. For example, if someone is cutting concrete with a powered saw. Suddenly, the harmless concrete will have been turned into a fine dust that can be inhaled and cause serious harm to the lungs.
COSHH Assessment | Top 5 Things to Remember
SAFETY DATA SHEETS
Read the SDS or MSDS thoroughly – all of your information from the manufacturer – sometimes this information can be quite broad in terms of the application of the substance and will usually relate to intense use of the product or worse-case scenario – so, if you can’t, get someone who can interpret it.
COMPATIBILITY
Separate incompatible chemicals to avoid risk of harm to health or fire hazards – This is often overlooked and not given enough priority- it’s part of the reason COSHH assessments can be so useful – because it gives you the chance to look at all of the COSHH substances you are using across an entire site or project.
Why is this important? Well, let’s look at mixing Ammonia & Bleach, for example.
One of the most common hazards occurs when chlorine bleach is mixed with ammonia or acids. The combination of ammonia and bleach produces dangerous chlorine gas, which in small doses can cause irritation to the eyes, skin and respiratory tract. In large doses, it can kill.
LABELLING
Make sure they are clearly and accurately labelled – ok, so this maybe seems obvious but its very easy for materials to be decanting or transferred to different container – what issue does this present – well firstly, it presents a risk to people of course, as they could confuse a hazardous material for something harmless and put themselves at risk.
Also, when it comes to environmental aspect, you need to be able to properly identify the material for safe and compliant disposal with your waste service provider.
You have to aim for simplicity here – there are COSHH labels out there that can be purchased which will allow you to fill in the information similar to how its presented on the original product packaging, which is what you should be aiming for.
VENTILATION
Provide ventilation and avoid excess exposure to sun/heat/sources of ignition – heat may make the chemicals more volatile so controlling levels of heat important and maintaining good airflow reduce the risk gases or vapour accumulating.
This is not only to mitigate any risk there might be of fire and explosion, but also helps to ensure the risk of harm to health – the vapours and gases can be irritant or can be toxic and act as an asphyxiant i.e. oxygen depletion is minimised
In some cases, you might want to put some form of oxygen monitoring or gas detection in place – as you would have around your boilers for carbon monoxide.
SECURE STORAGE
Store the substances securely and restrict use only to those who use or manage the chemicals – this stops them from getting into the hands of people who maybe aren’t aware of the potential risks – they haven’t been trained or informed on the hazards that exist.
