Filtermist LEV Log Books
A series of daily, weekly and monthly checks should be carried out on all LEV equipment in order to comply with guidelines published in HSG258. These specifically designed Log Books allow accurate recording of these LEV checks, together with comments on any corrective action required. A separate section for regular maintenance and unplanned repair work is also included. These records can then be used as evidence that HSE guidelines are being followed.
A Filtermist log book is supplied with each new extraction system and additional books, suitable for all extraction equipment, are available.
