This Directive is implemented in the UK by the Control of major accident hazard regulations 1999. The Commission draft proposal and the result of the public consultation could be seen at ''.

At this time the results of the Commission's deliberations on the revision of the proposal is not known, however HSE considers it useful to seek comments on the draft proposal since negotiations may proceed on the final adopted proposal very soon after its adoption by the European Commission in September 2001 and presentation to the European Council and European Parliament.

The proposal:
