What are Local Exhaust Ventilation (LEV) Systems?

Local Exhaust Ventilation (LEV) systems are a critical element of ensuring workplace safety by managing and minimizing workers’ exposure to potentially harmful substances like dust, fumes, and vapors. These systems work by capturing and removing contaminants at the source before they can disperse into the air, safeguarding employees from health risks associated with inhaling such pollutants.

LEV systems consist of various components, including hoods or enclosures placed near the emission source, ductwork to transport the contaminated air, an air cleaning device such as a filter or scrubber, and an exhaust fan to facilitate airflow. Proper design, installation, operation, and maintenance of LEV systems are essential to their effectiveness in protecting workers and maintaining a healthy work environment.

Regular LEV testing is crucial to ensure that these systems are functioning optimally and meeting regulatory requirements. Testing typically involves assessing airflow rates, checking for leaks or blockages in the ductwork, verifying the efficiency of air cleaning devices, and conducting measurements to confirm that contaminant levels are within permissible limits.

By implementing and maintaining effective LEV systems supported by routine testing protocols, employers can demonstrate their commitment to worker health and safety while complying with occupational health and safety regulations. Investing in proper ventilation not only protects employees but also contributes to overall productivity and well-being in the workplace.

In 2017, the HSE provided clear guidance on the des HSG258 ‘Controlling airborne contaminants at work: A guide to local exhaust ventilation (LEV). It describes the principles of deciding on, designing, commissioning and testing effective LEV.

More recently in 2022, the HSE produce the report HSE’s Occupational Lung Disease in Great Britain 2022 report, stating that more than 12,000 lung disease deaths have been related to air-borne exposure. LEV Testing is not only a legal requirement but helps to keep you and your workforce healthy. For more information on HSE guidelines click the link to visit the HSE Website.

Why are LEV systems necessary?

Local Exhaust Ventilation (LEV) systems play a crucial role in safeguarding workers from the detrimental impacts of dust, fumes, and vapors that emanate from diverse industrial operations. These systems are indispensable as they help in extracting harmful substances at the source, thereby preventing workers from being exposed to hazardous materials regularly. By eliminating or minimizing exposure to such harmful elements, LEV systems significantly reduce the risk of occupational diseases like chronic obstructive pulmonary disease and cancer among workers.

In addition to protecting the health and well-being of employees, LEV systems also contribute to maintaining a safe and compliant work environment. They assist companies in adhering to occupational health and safety regulations by controlling airborne contaminants effectively. Implementing LEV systems not only enhances workplace safety but also boosts overall productivity by ensuring that workers can carry out their tasks in a healthy environment free from harmful pollutants.

Regulations for Local Exhaust Ventilation Testing

The regulations for LEV testing companies are set out by the Health and Safety Executive (HSE) in the Control of Substances Hazardous to Health (COSHH) guidelines. It’s mandatory that every employer should maintain working conditions for the employees, and any employer who uses LEV techniques in the workplace must have the equipment examined and tested every 14 months to ensure it’s working effectively and safely. Our engineers hold the BOHS P601 certification, which is one measure of competency in this area. We pay close attention to the HSE guidelines while undertaking any examination, maintenance, or repair work.
