Local Exhaust Ventilation LEV
HSE 'Controlling exposure to stone dust' (published by TSO 2022 ISBN 978 0 7176 6736 9) describes these systems consisting 'of a hood (to capture dust/fume/mist), ducting, an air cleaner (to filter out the contaminant) and a fan (to pull air through the system).'
See the free HSE publication 'Controlling airborne contaminants at work: A guide to local exhaust ventilation'. (2017 ISBN: 978 0 7176 6613 3 Series code: HSG258 for more detailed information.
