A Guide to LEV Compliance for Small and Medium Businesses

Every year, workers across the UK suffer severe illness or even lose their lives due to exposure to airborne contaminants in the workplace.

One of the most effective ways to manage this risk is through a well-designed and maintained Local Exhaust Ventilation (LEV) system.

What Is LEV and How Does It Work?

LEV systems are designed to remove airborne contaminants, such as dust, mist, fumes, vapour or gas, before they can be inhaled. A typical LEV setup includes:

• A capture hood to collect the contaminated air
• Ducting to transport the air
• An air cleaner or arrestor to filter out harmful particles
• A fan to move the air
• A discharge point to safely release cleaned air

When correctly designed and maintained, LEV systems can significantly reduce the risk of occupational illnesses caused by inhaling harmful substances.

Why You Can’t Afford to Overlook LEV

While many businesses focus on day-to-day operations, LEV is one area where cutting corners can have serious consequences. Under the Control of Substances Hazardous to Health (COSHH) Regulations 2002, employers have a legal duty to protect staff from hazardous substances.

Here’s what you need to know:

Safeguarding Health

Exposure to airborne contaminants can lead to both short-term and long-term health issues, ranging from breathing difficulties to chronic occupational illnesses. LEV plays a necessary role in reducing that risk.

Staying Compliant

COSHH and the Health and Safety at Work etc. Act 1974 requires that exposure is either prevented or adequately controlled and this includes installing and maintaining LEV systems and ensuring staff are properly trained.

Avoiding Costly Consequences

Neglecting your LEV responsibilities can lead to the following:

• Increased sickness and absenteeism
• Legal action and fines
• Higher insurance premiums
• Long-term reputational damage

Getting the Design Right

Poorly-specified or designed systems won’t offer adequate protection. LEV must be tailored to your specific processes, environment, and workforce. A system that looks good on paper but isn’t practical for everyday use is unlikely to be used correctly.
