The document provides guidance on selecting equipment for use in hazardous areas based on the zone classification. It indicates that for Zone 0/1/2 areas, ATEX equipment marked II 1 GD, II 2 GD, or II 3 GD can be used for gases and combustible dusts. For Zone 1/2, equipment marked II 1 D, II 2 D, or II 3 D can also be used. The minimum ignition temperature and dust group must be considered for combustible dust areas.
