S.L. 646.12 Art. 3Assessment of major-accident hazards for a particular dangerous substance.

(1) Where the competent authority considers that a dangerous substance does not present a major-accident hazard, based on one or more of the following characteristics:

(a) the physical form of the dangerous substance under normal processing or handling conditions or in an unplanned loss of containment;

(b) the inherent properties of the dangerous substance, in particular those related to dispersive behaviour in a major- accident scenario, such as molecular mass and saturated vapour pressure;

(c) the maximum concentration of the substances in the case of mixtures; it shall notify the Commission together with supporting justification, including the information referred to in sub-regulation (2).

(2) For the purposes of sub-regulation (1), information necessary for assessing the health, physical and environmental hazard properties of the dangerous substance concerned shall include:

(a) a comprehensive list of properties necessary to assess the dangerous substance’s potential for causing physical, health or environmental harm;

(b) physical and chemical properties (for instance molecular mass, saturated vapour pressure, inherent toxicity, boiling point, reactivity, viscosity, solubility and other relevant properties);

(c) health and physical hazard properties (for instance reactivity, flammability, toxicity together with additional factors such as mode of attack on the body, injury to fatality ratio, and long-term effects, and other properties as relevant);

(d) environmental hazard properties (for instance ecotoxicity, persistence, bio-accumulation, potential for long-range environmental transport, and other properties as relevant);

(e) where available, the European Union classification of the substance or mixture;

(f) information about substance-specific operating conditions (for instance temperature, pressure and other conditions as relevant) under which the dangerous substance is stored, used and/or may be present in the event of foreseeable abnormal operations or an accident such as fire.
