Classified Area

A designated area in a motor fuel dispensing facility where the use of specially prescribed ignition resistant equipment is required. 

NFPA 30A, the National Electrical Code (NFPA 70), and the International Fire Code all identify certain zones adjacent to gasoline dispensers, vent pipes, tank fill openings, etc., as being classified as Class I, Division 1 or Class I, Division 2.

The classification assigned to the zone is a reflection of the potential for fire or explosion in that particular zone. In a Class I, Division 1 area, for example, the only motors permitted are those designed to be explosion proof.
