Local Exhaust Ventilation (LEV) Testing

Local Exhaust Ventilation (LEV) systems are an essential component of any workplace safety plan, as they help to control and reduce the exposure of workers to dust, fumes, and vapours that can be hazardous to their health. In this article, we’ll examine what LEV systems are, why they’re necessary, and what is involved in LEV testing.

    Understanding Local Exhaust Ventilation (LEV) Systems

    LEV System and its basic components

    LEV Testing Diagram

    An LEV System (Local Exhaust Ventilation) system is an engineering system that captures dust, vapours, and fumes at their source, minimising the risk of workers breathing in contaminated air.

    Most LEV systems will have five basic components.

    1. The Hood captures the contaminated air

    2. Ducting provides a pathway through which contaminated air travels to the air cleaner.

    3 . The Air Cleaner filters the contaminated air.

    4. The Fan moves contaminated air through the hood and ducting system to the exhaust stack.

    5. The exhaust Stack releases the contaminated air to the outside

    In reality, each LEV system will look very different and be specific to the needs and requirements of each business. Selecting the right LEV system can be confusing…

    Poor design, installation and maintenance can reduce its capability to capture and contain contaminated air. It may introduce new risks to the workplace, such as excessive noise, vapours, or dust in a ventilation duct catching on fire. For these reasons, an LEV system should only be designed and installed by a competent and qualified professional.

    What are LEV systems?

    LEV systems are designed to capture pollutants at the source before they have a chance to spread throughout the work area. They consist of a series of hoods, ducts, and filters that work together to extract contaminated air and transport it away from the workers. This is typically done through a fan or blower, which pulls the contaminated air into the hoods and then pushes it through the ducts and filters before discharging it into the atmosphere.

    Why are LEV systems necessary?

    LEV systems are necessary because they protect workers from the harmful effects of dust, fumes, and vapors that can be generated by a wide variety of industrial processes. Without LEV systems, workers would be exposed to these pollutants on a regular basis, putting them at risk of serious health problems such as respiratory illness and cancer.

    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.
