Posted By Mark Talbot I have no experience, but you mention pacemakers ... just in case you haven't considered them, I would extend that to all implants.

Posted By Hilary Charlton Hi We use rare earth magnets which also have a very strong electromagnetic field and these are the precautions that we take: We put very strict guidelines in our maintenance manuals about the risk arising from rare earth magnets - you should not get wris[expletive deleted]ches, credit cards, etc anywhere near them. Our maintenance instructions are produced in all the languages and also have the pictograms showing electromagnetic fields. As long as our product is not open then the magnetic field is contained - one assumes that anyone opening the outer casing will read the maintenance instructions first! (this is a highly technical industrial product and you may have to take other precautions depending on the complexity of your product). We do not allow people with pacemakers into the area where the components with the magnets on are assembled, the rare earth magnets can reset a pacemaker back to factory settings leading to fibrillation. There are signs up and we ask the question of every visitor. We have advised everyone in that area that if they happen to be struck by a cardiac arrest they will be dragged to an area where we can use the AED otherwise we might get a false reading and shock them when it is not necessary as the electromagnetic field can also affect the use of a defibrillator. This is certainly an area that, although it does not need an excessive amount of work, will require awareness training of all staff so that no one inadvertently causes a serious injury-cum-malfunction. I hope this helps in some way. Hilary
