Article 4 'Evaluation of hazards from a specific dangerous substance': Member States must, where it has been demonstrated based on the criteria in Annex VI Part 3 that an individual substance cannot create a major-accident hazard - particularly because of its physical form + properties + classification + concentration - request a Commission decision excluding it from Annex I (Article 4). This is the mechanism by which substances may be removed from the qualifying-quantity list. Article 5 sets the general obligations of the operator: the operator is required to take all measures necessary to prevent major accidents + to limit their consequences for human health + the environment. Article 5(2) the operator must demonstrate to the competent authority at any time that all the necessary measures specified in this Directive have been taken (the burden of proof rests on the operator). Article 5(3) the obligations of the operator apply also where the operator uses a contractor or supplier to perform a function within the establishment.
