I have a contractor to do the 14 monthly check, but now the company want us to do it in house. The company has he machine to check the air flow etc, my question is, do we need to send maintenance on a course

i worked with LEV (Bakery) and have looked into this it is a very complicated subject and the LEV is affected by a lot of variables you can get courses which are run by the BOHS and cost approx £1000 5 day course http://www.bohs.org/educ...nations/course-providers who ever does it must be very good at maths as there is a lot (and i mean a lot) of calculations involved we looked quite deeply at this and in the end we decided to stay with a outside contractor to do our check hope this helps
