LEV TESTING
Professional Local Exhaust Ventilation Testing & Compliance
Local Exhaust Ventilation (LEV) systems are designed to protect employees from hazardous airborne substances generated during industrial processes. These may include dust, fumes, mist, vapour and gas.
Without effective control, exposure to airborne contaminants can lead to health risks ranging from skin and respiratory irritation to serious long-term illnesses. A properly designed and regularly tested LEV system is therefore critical to maintaining a safe, compliant and productive workplace.
integratedAIR provides professional LEV testing services carried out by qualified P601 engineers, ensuring your system operates in full compliance with current legislation and industry guidance.


What Is LEV?
Local Exhaust Ventilation is an engineered system that:
- Captures contaminants at source
- Prevents their release into the workplace atmosphere
- Transports contaminated air safely away
- Filters or discharges it in a controlled manner
LEV systems are commonly used in manufacturing, fabrication, processing and industrial environments where airborne hazards are generated as part of normal operations.
Why LEV Testing Is a Legal Requirement
Professional LEV testing is not optional. It is a legal obligation under:
- Control of Substances Hazardous to Health Regulations 2002 (COSHH)
- Health and Safety Executive (HSE) guidance
- HSG258: Controlling airborne contaminants at work
Under COSHH Regulation 9, LEV systems must be thoroughly examined and tested at least every 14 months, or more frequently depending on the risk profile of the application.
Failure to comply can result in:
- Increased risk to employee health
- Enforcement action from the HSE
- Invalidated insurance policies
- Operational disruption
- Reputational damage
Regular testing ensures your system continues to perform as originally designed and provides documented proof of compliance.
Our LEV Testing Service
Our P601-qualified service engineers conduct comprehensive LEV examinations in line with HSG258 guidance.
Our testing process includes:
- Visual inspection of system components
- Airflow measurement and performance verification
- Hood capture efficiency checks
- Static pressure readings
- Fan and filter condition assessment
- Identification of defects or performance issues
- Full written compliance report with recommendations
Each report clearly details whether the system is performing effectively and highlights any remedial actions required.


Protecting Your Workforce and Your Business
A high-performing LEV system delivers significant operational and commercial benefits.
Key Benefits of Effective LEV Systems
- Protect employee health and wellbeing
- Improve workplace cleanliness and safety
- Reduce housekeeping and maintenance costs
