Congratulations, scorza, you finally managed a legitimate criticism of the EU
EU-wide regulation does have the downside that improvements in local regulation can be stymied and there are real and valid cases where this has happened. Another example would be cycle helmets where the UK downgraded from the stricter British Kitemark standard for cycle helmets to a lower standard agreed at EU level.
Against this, however, you need to consider the wider picture of EU safety regulation: the EU has shown itself to be highly effective in pushing improved environmental and health standards and, because of its larger weight, it is able to drive the adoption of these standards across an industry. Good examples of this would be the improved Euro emissions standards for cars, or the cleanup of British waterways and beaches.
The lack of localism in law making is the largest issue with the EU (if we ignore the CAP of course). Also the further away from where the money is collected the less care is on spending it. Just look at the farce that is having the parliament in Strasbourg and Brussels.
