Fundamentals of Class II, Division 2 - Hazardous Areas!

Class 2, Division 2 is defined as a location in which combustible dust may be suspended in the air as a result of infrequent malfunctioning of handling or processing equipment. In another words, under normal operating conditions, there would not be sufficient dust present to interfere with the operation of electrical or other equipment.  It is unlikely that an explosive dust/air mixture will occur in this location.
