When Can You Make a Personal Injury Claim?

Methyl ethyl ketone, better known as MEK, is an industrial solvent which can become a health risk if workers face MEK exposure at work. Employers are required to have strict safety protocols in place to avoid any exposure as it affects the nervous and respiratory systems, as well as eyes and skin. MEK is widely used as it cuts through grease, dissolves coatings and generally can speed up production time.

If you’ve been exposed to MEK at work and you’re now dealing with symptoms, you may be wondering whether you can make a personal injury claim. Legally, if your employer failed to protect you and you suffered harm as a result, you may be entitled to compensation.

 

What Is MEK?

MEK is a solvent which is flammable and colourless. It also evaporates quickly, which makes it ideal for:

 

• Paints and coatings
• Adhesives
• Printing inks
• Degreasing machinery
• Resin and plastics manufacturing

 

While its fast evaporation is useful for production, it also means fumes build up quickly. Workers often underestimate this because many people stop noticing the smell long before the exposure level drops.

 

How MEK Exposure Happens at Work

Most exposure happens through inhalation, but skin contact is also common. In many workplaces, exposure isn’t dramatic, but gradual, repeated, and easy to overlook.

Typical scenarios include:

 

• Working in enclosed or poorly ventilated areas
• Cleaning machinery with MEK in cramped spaces
• Handling adhesives without proper gloves
• Dealing with spills using rags instead of proper containment
• Using outdated extraction systems that haven’t been serviced in years

MEK exposure often spikes during cleaning tasks, not production. This is because workers crouch inside machines or lean over parts, exactly where ventilation is weakest.

 

Symptoms and Health Effects of MEK Exposure

MEK affects the central nervous system, respiratory system, and skin. Early symptoms often mimic tiredness, which is why many workers brush them off.

Common symptoms include headaches, fatigue, eye and throat irritation and skin redness or cracking.

Workers frequently assume they’re “just tired” or dehydrated, but a telling sign is when symptoms ease on days off or during holidays.

At higher or prolonged exposure levels, MEK can cause:

 

• Loss of coordination
• Shortness of breath
• Chemical burns
• Long‑term neurological effects

 

Your Employer’s Legal Duties 

In England and Wales, MEK is regulated under COSHH (Control of Substances Hazardous to Health). This means employers must:

 

• Assess the risks of MEK exposure
• Provide proper ventilation and extraction
• Supply suitable PPE (e.g. not just any gloves as MEK breaks down some materials in minutes)
• Fit‑test masks rather than simply handing them out
• Train workers on safe handling
• Monitor exposure levels
• Substitute MEK with safer alternatives where possible

 

A common issue is that risk assessments are outdated and processes have changed.

 

When MEK Exposure Becomes a Personal Injury Claim

You can make a claim if:

 

You were exposed to MEK at work

Your employer failed to take reasonable steps to protect you

You suffered illness or injury as a direct result of the exposure

 

This applies whether the exposure was:

 

• A one‑off incident
• A gradual build‑up over months or years
• Caused by poor training
• Linked to inadequate PPE
• Due to faulty or poorly maintained ventilation

 

Employers sometimes try to blame workers for “misusing” chemicals, but employers are expected to design systems that protect workers even when mistakes happen.

 

Real‑World Situations That Often Lead to Claims

1. Poor Ventilation

A worker uses MEK‑based cleaners in a workshop where extraction fans haven’t been serviced in years. Airflow drops gradually, and no one notices until symptoms appear.

 

2. Gloves That Don’t Protect

Generic “multi‑purpose” gloves are handed out, but MEK dissolves them. Workers only realise when their skin starts cracking.

 

3. No Fit‑Testing for Masks

Masks are provided, but they don’t seal properly. Workers inhale fumes despite thinking they’re protected.

 

4. Pressure to Work Through Symptoms

In fast‑paced environments, workers often feel they can’t slow down or report discomfort. This culture contributes to long‑term exposure.

 

5. Spill Mismanagement

Small spills are wiped up with rags, increasing both inhalation and skin contact.

 

6. Long‑Term Exposure Without Monitoring

A printing worker develops neurological symptoms after years of daily exposure. No monitoring was ever carried out.

 

These examples highlight a recurring theme: the harm is preventable.

 

How to Prove Your Claim

Evidence strengthens your case. Useful documentation includes:

 

• Medical records
• Workplace incident reports
• Photos of the environment
• Witness statements (often powerful as colleagues may share similar symptoms)
• PPE logs
• COSHH assessments
• Training records

A solicitor can obtain most of this, but your own early notes can be invaluable.

 

Time Limits for Making a Claim for MEK Exposure

You usually have three years from the date of exposure, or the date you first realised your symptoms were linked to your work.

We’ve seen that some workers, who have been exposed to MEK, only make the connection after speaking to a doctor familiar with industrial exposure. That’s often when the clock starts.

 

What Compensation Can Cover

A successful claim for compensation can include:

 

• Pain and suffering
• Lost earnings
• Future loss of earnings
• Medical treatment
• Travel costs
• Care and support
• Long‑term health impacts

 

Why Early Legal Advice Helps

MEK symptoms overlap with other conditions, and employers sometimes deny responsibility. A specialist solicitor can help you understand whether you have a valid claim. If so, they will help you to gather evidence, access medical experts and negotiate with insurers. Keep the time limit in mind as you don’t want to leave it too late to claim.
