If you work with chemicals, cleaning products, dust, or biological agents, there's a good chance COSHH applies to you. And so does the law. The Control of Substances Hazardous to Health Regulations 2002 (COSHH) isn't just a rulebook for employers. Employees have their own set of clear, legally binding responsibilities too.
This guide breaks down exactly what COSHH employee responsibilities look like in practice, why they matter, and how proper training can make the difference between a safe workplace and a very costly one.
What is COSHH and why should employees care?
COSHH stands for the Control of Substances Hazardous to Health. It's a set of UK regulations introduced to protect workers from the dangers of hazardous substances such as industrial chemicals, cleaning agents, fumes, dust, vapours, and certain biological materials.
You might think of COSHH as the employer's problem to solve, and yes, employers carry the heavy end of the compliance burden. But the regulations are explicitly two-way. Employees have legal duties under COSHH too, and ignoring them isn't just dangerous. It can result in disciplinary action, civil liability, or worse.
The numbers make sobering reading. According to the [Health and Safety Executive HSE, approximately 13,000 people die every year from occupational lung disease and cancers linked to past exposure to hazardous substances at work. Many of these deaths were preventable. COSHH exists to stop history repeating itself, but only if everyone in the workplace takes it seriously.
What counts as a hazardous substance?
Before diving into COSHH employee responsibilities, it helps to understand what we're actually talking about when we say "hazardous substance."
Under COSHH, a hazardous substance is broadly anything that can cause harm to a person's health. This includes:
- Chemicals: solvents, acids, cleaning fluids
- Dust: wood dust, flour dust, silica
- Fumes and vapours: welding fumes, paint sprays
- Biological agents: bacteria, viruses, mould
- Gases: carbon monoxide, chlorine
These substances can enter the body through inhalation, skin contact, ingestion, or injection via cuts or punctures. The harm they cause might be immediate, like a chemical burn, or long-term, such as occupational asthma developing after years of dust exposure.

COSHH employee responsibilities: The full picture
So what exactly are employees required to do under COSHH? Here's a clear rundown of your key obligations:
1. Follow control measures
Your employer should have established control measures: procedures and systems designed to reduce your exposure to hazardous substances. As an employee, you are legally required to follow these measures. This isn't optional. Bypassing controls, even to save time, puts you and your colleagues at risk and breaches your legal duties.
2. Use PPE correctly, every time
Personal protective equipment (PPE) exists for a reason. Whether it's gloves, safety goggles, a face mask, or a full respirator, your employer provides it because the risk assessment says you need it. COSHH employee responsibilities include wearing PPE correctly, every single time it's required. That means:
Putting it on properly before starting work
Never removing it mid-task because it's uncomfortable
Taking it off before eating, drinking, or leaving a hazardous area
Storing it correctly after use
Disposing of contaminated PPE safely
3. Report defective equipment
If PPE is damaged, equipment isn't working as it should, or safety controls appear to have failed, you are required to report it immediately. Don't assume someone else will notice. A faulty extraction system or a torn glove might seem like a minor inconvenience, but it could represent a serious risk to health.
4. Report accidents, spills, and near misses
COSHH employee responsibilities extend to incident reporting. If a spill occurs, if you're accidentally exposed to a hazardous substance, or if something nearly goes wrong, you must report it. This isn't about blame. It's about ensuring the right response happens quickly and that lessons are learned to prevent future incidents.
5. Attend health surveillance when required
For employees regularly exposed to certain hazardous substances, employers must arrange health surveillance such as lung function tests or skin assessments. Attending these check-ups isn't just good sense; it's a legal obligation. They exist to catch early signs of harm before they become serious conditions.
6. Attend COSHH Training
One of the most important COSHH employee responsibilities is a willingness to engage with training. If your employer provides COSHH training, you are required to take part. Training equips you with the knowledge to recognise hazards, understand the risks, and work safely around hazardous substances day to day.
Why COSHH employee responsibilities matter: A real-world example
It's easy to treat health and safety regulations as abstract rules on a page. A real-world case study from the HSE brings the stakes into sharp focus.
Workers at a Bristol company were exposed to hazardous photographic chemicals over a four-year period, with three employees developing severe allergic contact dermatitis as a result. One employee endured years of his skin blistering, cracking, and weeping; another's hands became so badly swollen that he couldn't do up his shirt buttons without his fingers splitting open.
According to the HSE's published case study, the company was fined a total of £100,000 and ordered to pay £30,000 in costs. The breakdown was: £30,000 for breaching the Health and Safety at Work Act 1974, £10,000 for each of six separate COSHH breaches covering failures around risk assessments, controlling chemical exposure, and not providing health surveillance, plus a further £10,000 for failing to report a case of allergic contact dermatitis.
The lesson here isn't just about employer failures. When control measures aren't followed, health surveillance is skipped, and incidents go unreported, everyone in the chain bears some responsibility.
The employer's role: Setting the scene
COSHH compliance is a shared effort, and it's worth understanding what employers are required to put in place so that employees can fulfil their own responsibilities.
Employers must carry out a COSHH risk assessment to identify hazardous substances in the workplace and the level of risk they present. Based on this, they must implement appropriate control measures, provide suitable PPE, establish emergency procedures, arrange health surveillance where necessary, and provide adequate training and information to all staff.
Without this foundation, employees are left trying to meet their obligations without the tools or knowledge to do so. That's why employer compliance and COSHH employee responsibilities go hand in hand.
Training your team on COSHH employee responsibilities
Understanding COSHH obligations is one thing. Turning that understanding into consistent, confident behaviour across a workforce is quite another. That's where structured training makes all the difference.
Properly trained employees are better equipped to:
Recognise hazardous substances and understand the risks associated with them
Read and interpret safety data sheets and COSHH symbols
Follow control measures and use PPE correctly
Know when and how to report incidents or concerns
Contribute to a genuinely safe working culture rather than just ticking compliance boxes
Training doesn't need to be expensive, time-consuming, or disruptive to daily operations. Online COSHH training has made it far more accessible for businesses of all sizes.

Quick checklist: Are your employees meeting their COSHH responsibilities?
Use this checklist to assess where your team currently stands:
Do employees know which substances in your workplace are hazardous?
Are control measures being followed consistently?
Is PPE being used correctly and stored properly?
Do employees know how and where to report accidents, spills, or defective equipment?
Are health surveillance appointments being attended where required?
Has every relevant employee completed COSHH awareness training?
Are training records up to date and accessible for inspection?
If you've ticked all of those boxes, well done. Your workplace is on the right track. If not, the good news is that addressing the gaps is straightforward with the right training in place.
The bottom line
COSHH compliance isn't just a box-ticking exercise. It's a genuine commitment to protecting the health and wellbeing of the people in your workplace. COSHH employee responsibilities are clear, legally binding, and designed to create a working environment where hazardous substances are handled safely and professionally.
For employers, the most powerful step you can take is investing in quality COSHH training for your team. It reduces risk, supports legal compliance, and builds a culture where safety is taken seriously, not just during an inspection, but every single day.
