Hazardous Locations - Class I, Division 2

Hazardous locations are classified in North America, using two different classification systems: the Class-division and the Zone system. It is important to know how they differ. This animation focuses on Class 1 Division 2.

Class 1 means that the location contains flammable gases, flammable liquid-produced vapours, or combustible liquid produced vapours.

Division 2 means a location where an explosive atmosphere does not exist under normal operating conditions but, if it does occur, it will persist for a short period only. A Division 2 area might be created during repair or maintenance activities, accidental rupture of a vessel or container or failure of a ventilating system. Division 2 is also the area immediately adjacent to a Division 1 location.
