Chemical safety in the workplace can feel daunting, with its acronyms, legal duties and the worry of getting something wrong. The good news is that it does not have to be overwhelming. This guide explains what chemical safety really means, the regulations that apply to your business, and the simple steps that keep your people protected and your business compliant. You will also see exactly where COSHH fits in, so you can get it right with real confidence.

What is chemical safety?

Chemical safety is about using and managing hazardous substances at work in a way that protects your people and the wider environment. The catch is that not every harmful substance comes with an obvious label. Even everyday things like wood dust and welding fumes can cause real harm over time.

It covers both natural and manufactured chemicals, including substances thrown off by your own workplace processes. The rules follow a substance through every stage it passes through, from its natural state and extraction to its production, transport, use and disposal. Put simply, if something in your workplace could affect your team’s health, chemical safety applies to it.

Why chemical safety matters

There are three big reasons to take it seriously.

First, it is the law. As an employer, you have a legal duty to assess and control the risks from hazardous substances, and the rules exist to keep you, your people and your business safe from harm.

Second, it protects your people. Working with hazardous substances can carry real health risks, from minor skin irritation through to respiratory problems, neurological conditions and, in the worst cases, cancer. Some effects appear quickly, while others build quietly over years.

Third, it protects your business. Falling short can mean fines, enforcement action and legal claims, along with the reputational damage that follows. Few people want to work for, or buy from, a business that does not look after its team.

Sue recommends starting with a simple inventory of every hazardous substance on site, however harmless it looks. You cannot control a risk you have not written down, and that one list makes everything that follows far easier.

The regulations that govern chemical safety

Several sets of rules sit behind chemical safety in the workplace. You will not need all of them, but it helps to know which ones might apply to you.

REACH

REACH stands for the Registration, Evaluation, Authorisation and Restriction of Chemicals. It applies to chemical substances and to the products made using them, from industrial chemicals through to paint and furniture. Businesses that manufacture or place chemicals on the market must identify the risks involved and show how they are managed. Since the UK left the EU, businesses in Great Britain follow UK REACH.

COSHH

COSHH stands for the Control of Substances Hazardous to Health. It is the legal framework that protects anyone working with hazardous substances, setting out how they should be handled, stored and worked with so your team stays safe. It reaches wider than obvious chemicals too, covering by-products like dust, fumes, mists and vapours, and even biological agents such as viruses and bacteria. For most workplaces, this is the set of rules you will lean on most.

COMAH

The Control of Major Accident Hazards regulations, or COMAH, help businesses prevent major incidents involving dangerous substances. They focus on making sure the responsible people understand the risks and manage them safely, and they are enforced by five public bodies working in partnership: the Health and Safety Executive, the Environment Agency, the Scottish Environment Protection Agency, Natural Resources Wales and the Office for Nuclear Regulation.

CHIP and CLP

The Chemicals (Hazard Information and Packaging for Supply) regulations, known as CHIP, placed clear duties on the suppliers of chemicals to identify hazards and provide the right labels and safety data sheets. CHIP has since been replaced by the CLP Regulation on the classification, labelling and packaging of substances and mixtures, which carries that responsibility forward.

Carriage of Dangerous Goods

If your business moves dangerous goods, the Carriage of Dangerous Goods regulations place a duty of care on everyone involved. Hazardous goods are grouped into classes based on the harm they could cause, and anyone handling them needs to know how to reduce the risk of spillage, fire, chemical burns or environmental damage in transit.

What COSHH means for you day to day

COSHH is the one you will use most often, so it is worth being clear on who is responsible for what. A good recognised COSHH course gives the people handling substances the knowledge to get this right from the start.

As an employer, your duties include controlling or preventing exposure to hazardous substances, often through measures like enclosure, better ventilation and the right personal protective equipment. You are expected to put control measures in place, give your team clear information, instruction and training, and have procedures ready for accidents and emergencies. You also need to carry out COSHH risk assessments, keep exposure within the Workplace Exposure Limit where one applies, arrange health surveillance for anyone regularly exposed, and check that safe working practices are actually being followed.

Your team share the responsibility too. Employees are expected to work safely and help their colleagues do the same, follow the procedures in place, wear and store their PPE correctly, and report any accidents, spillages or breakages. They should also attend health check-ups when asked, make proper use of washing and welfare facilities, and keep their own training up to date.

Sue recommends keeping your COSHH assessments somewhere everyone can find them, not locked in a folder on one manager’s desk. If an inspector asks, you want to reach for them in seconds, and your team should be able to check them just as easily.

How to make COSHH simpler, step by step

COSHH has a reputation for being complicated, but it becomes far more manageable once you break it into five clear steps.

1. Identify your hazardous substances

Start by listing every hazardous substance in your workplace. Each one should come with a Safety Data Sheet from the supplier, which is your first and best source of information.

2. Assess the risks

For each substance, think through what harm it could do, how people might be exposed, whether that is by breathing it in, touching it or swallowing it, and how often and for how long that exposure happens. If assessments are new to your team, risk assessment training gives them a solid, repeatable method to follow.

3. Put controls in place

Next, decide how to reduce the risk. That might mean swapping a substance for a safer alternative, improving ventilation, tightening your working procedures or providing the right PPE.

4. Record what you find

Write up your findings and control measures in a COSHH assessment. Keep it current and easy to reach, because this is the document regulators will want to see.

5. Review regularly

Revisit your assessment whenever something changes, and on a regular basis anyway, so it keeps pace with how your business actually works.

Common COSHH challenges, and how to beat them

Most businesses hit the same few sticking points. Here is how to get past them.

If you are short on information about a substance, go back to the Safety Data Sheet, use the guidance on the HSE website, or bring in a health and safety consultant who works with COSHH every day.

If the sheer complexity feels overwhelming, simplify wherever you can with templates and checklists for each stage of the process.

If cost is a worry, remember that preventing an incident is almost always cheaper than dealing with the health issues and legal action that can follow one.

And if time is tight, break the work into smaller tasks so it never becomes the job you keep putting off.

Enforcement and what non-compliance really costs

When employers fail to control exposure, the consequences can be severe for everyone involved. Workers can develop life-changing conditions, and businesses can face heavy fines and, in the most serious cases, prison sentences. The size of any penalty usually reflects how serious the breach was and how much harm resulted.

Real cases show how this plays out. One car body shop was fined £20,000 after failing to protect staff from the fumes of isocyanate paints, which can cause occupational asthma. In another case, workers at a Bristol business were exposed to hazardous chemicals over four years and developed allergic contact dermatitis, a painful condition that makes the skin blister, crack and weep. The company faced a substantial fine on top of its costs. The lesson is simple: getting chemical safety right is far cheaper than getting it wrong.

Sue recommends treating every near miss as a free warning. Recording the spill or breakage that did not hurt anyone this time is often exactly what stops the one that would.

When to bring in expert help

You do not have to tackle all of this alone. It is worth bringing in support when your risks are hard to assess or control, when this is your first time building a COSHH plan, or when you handle high-risk substances that call for specialist advice. Expert health and safety consultancy also takes the pressure off, so it is not all resting on your shoulders if something goes wrong.
