Vic - I am not exactly sure how your regulatory body in the UK works, but perhaps you could contact them and ask them to open a "Comment Period" on the rule. In the US, if you can show a valid concern / issue with a rule, you can request a review (not that it will always happen). It is a slow moving process, but if you can prove your point through common workplace examples, someone may listen. I have seen this happen in the US with OSHA as well as other regulatory bodies. If you can prove an unsafe practice in the rule by using several examples, it will go a long way towards maiking your case.
