LEV Good Practice Guides

Practical Guidance Developed by LEVCentral

The LEV Good Practice Guides series has been developed by LEVCentral to provide practical guidance on the design, commissioning, testing and management of Local Exhaust Ventilation systems.

Unlike formal standards and guidance documents, these papers are intended to share practical experience, lessons learned and good practice developed from real-world LEV applications.

The series complements HSE, BOHS and CIBSE guidance and is intended for designers, commissioners, testers, duty holders and anyone responsible for ensuring LEV systems perform effectively.
