What is LEV Testing?
LEV testing, or Local Exhaust Ventilation (LEV) testing, is an essential process that ensures an LEV system is working properly and effectively controlling exposure to substances hazardous to health. Under HSE regulations, businesses that use extraction equipment to remove airborne contaminants must conduct regular LEV testing to comply with health and safety laws and maintain a safe working environment.
Why is LEV Testing Important?
Many workplaces produce hazardous substances, such as harmful dust, fumes, vapours, and airborne contaminants, which can pose serious health risks to employees. Without adequate control from a person competent in dealing with LEVs, workers can develop respiratory issues and long-term health conditions. LEV inspections help businesses:
- Ensure LEV equipment is functioning correctly
- Meet HSE guidelines and COSHH regulations
- Prevent employees from falling ill due to exposure to substances hazardous to health
- Maintain compliance with health and safety standards
By having a qualified, competent person control the LEV system – someone who has completed the training course – it is possible to keep your employees safe.
Legal Requirements for LEV Testing
According to the Health and Safety Executive (HSE) website, LEV testing is a legal requirement under the Control of Substances Hazardous to Health (COSHH) regulations. Businesses must ensure their local exhaust ventilation system undergoes a thorough examination and visual inspection by a competent person at least every 14 months. Some industries require more frequent testing, depending on the level of exposure to harmful substances.
What Does an LEV Test Involve?
An LEV inspection involves a detailed and systematic examination of the LEV system to determine if it is working effectively. A qualified engineer or a competent person will assess the technical performance of the system through:
- Visual examination – Checking for signs of damage or wear in the ventilation system
- Static pressure testing – Measuring airflow and suction levels
- System effectiveness assessment – Ensuring the system captures and removes contaminants efficiently
- Test reports – Documenting the findings and recommending necessary maintenance work
Businesses receive a commissioning report’s performance details, confirming whether the installed LEV system is working in an efficient working order.
How Often Should LEV Testing Be Conducted?
While regular testing is required annually, certain workplaces dealing with high levels of hazardous substances may need more frequent testing. Regular LEV testing services not only help businesses comply with industry standards but also ensure employees stay safe in the workplace.
Who Needs LEV Testing?
LEV testing applies to different industries, including but not limited to:
- Manufacturing
- Foods processing
- Recycling
- Welding and metalworking
- Pharmaceutical production
- Chemical processing
- Woodworking
- Construction industry
- Automotive refinishing
Any industry that uses extraction systems to control airborne contaminants must adhere to HSE guidance and perform regular inspections.
Maintaining a Safe Working Environment
Proper LEV testing and maintenance work ensures that a company is operating in compliance with safety laws while protecting workers from exposure to harmful substances. By conducting frequent testing, businesses can prevent costly fines, avoid health risks, and maintain compliance with their company’s insurance.
For businesses looking for LEV testing services, it’s important to work with a qualified engineer who can provide practical advice and ensure most systems are in good repair. Ensuring a reliable job will keep workplaces compliant with safety standards while maintaining an efficient working order.
