Posted By Chris Packham Mark In theory it is LEV so should be tested. However, more frequent testing or at least examination and maintenance may be needed, depending upon the type of extraction you are using. For example, I have found that the tip extraction systems that are fitted to some soldering irons quickly clog with waxy deposits from the flux and need cleaning frequently. Those which use an activated carbon filter may also need more regular checking. These are also sometime problematic in their positioning, particularly when the solderer is working on a larger object, e.g. a printed circuit board, as the capture may not be adequate. I have found that in many cases downdraft benches are the best solution. Minimum obstruction for the worker, optimum capture and, due to the large surface area, less tendency to clog. You can actually get units that simply are placed on the workbench and attached to an extraction unit. Chris

Posted By Jane Bastow They are LEV, they need regular user checks recorded in a Log Book (manufacture/suppier should have supplied one and set out the types/frequencies and methodology). They should have been subject to a commissioning LEV inspection and training given in the maintenance and inspection required to be done by the operators (Supplier should have informed you of all of this - in practice I don't know of any supplier who even understands, let alone complies with his legal obligations in this regard) Inspection & test is required at least every 14 months, in practice this should be treated as an annual obligation; and most importantly the frequency of this testing should be more frequent if the examiner recommends so - as in the case of the problem with high maintenance requirement mentioned in earlier post, which may make say 6 monthly inspection desirable. The main problem sounds like failure to design and implement an appropriate maintenance and user check program to keep the equipment in good functional condition. There is a statutory obligation on the employer to maintain LEV in good serviceable condition.
