The EU announced that the directive 2004/40/EC will be replaced by a proposal of the European Commission (EC). In this work the EC limit values and the 2004/40/ECs limit values are compared to MR exposure data. 37 MR workers were asked to wear a field probe in the magnet room (up to 7T). Results show that the new limits (both peak and average) can be exceeded during routine work. With an optic/acoustic response system the ECs proposal can help reducing transient effects like vertigo or magnetophosphenes.
