Article 2 1.  Member States may not, on grounds of safety requirements for the design and construction of elec- trical equipment, prohibit the sale or free movement or the use, for its proper purpose, of electrical equip- ment for use in a potentially explosive atmosphere which complies with the provisions of this Directive and of Directive 76/117/EEC, with regard to the safety features covered by this Directive. 2.
