Every employer has a legal responsibility to ensure their staff is not exposed to dangerous dust emissions at work.
LEV inspection and testing must be done by qualified engineers who knows what they’re doing and, importantly, understands how the Local Exhaust Ventilation (LEV) systems function.
Pennaire Filtration delivers COSHH LEV testing and thorough examination services across the UK, carried out by British Occupational Hygiene Society (BOHS) P601 certified engineers. From LEV assessment to full Thorough Examination and Test (TExT) reporting, we keep your business compliant and your workers protected.
A LEV Thorough Examination and Test commonly referred to as a TExT or LEV test is a structured, in-depth assessment of your Local Exhaust Ventilation system. Dust, fumes, and airborne particles need to be properly controlled to reduce any risk to workers’ health, which is why a regular LEV Thorough Examination and Test (TExT) helps to maintain a safe working environment.
Not only does it check that extraction systems are operating effectively, but it provides essential protection for on-site employees and helps businesses avoid the costly consequences of not meeting their legal obligations.
Our LEV test report will provide a comprehensive overview of your system’s performance, including:

Workplaces with Local Exhaust Ventilation (LEV) equipment designed to prevent or control exposure to dust emissions and hazardous substances must comply with the Control of Substances Hazardous to Health Regulations (COSHH) 2002 (specifically, Section 9).
Under COSHH Regulation 9, businesses in the UK must arrange a thorough examination and test of their LEV equipment at least once every 14 months, and a record of every LEV test must be kept for at least five years, including details of any remedial work carried out as a result. How often should LEV be inspected? Pennaire recommends a full LEV examination annually, with additional LEV system inspections every six months as part of a preventative maintenance programme. This exceeds the statutory minimum and gives you the earliest possible warning of system degradation. Failure to test can result in HSE enforcement, prosecution, and significant financial penalties as well as serious risk to your employees’ health.
This approach is informed by the principles of LEV design and operation from the Health and Safety Executive (HSE), published in ‘HSG258 Controlling airborne contaminants at work: A guide to local exhaust ventilation (LEV)’. However, it must be noted that these are guidelines. Every LEV system should be treated individually and require it’s own design and engineering.
COSHH-certified LEV testing from Pennaire Filtration provides peace of mind that your extraction systems are working as they should and ensure that you remain fully compliant with the relevant regulations.
Our team of engineers provides LEV testing services across multiple sectors where compliance is essential, including:
