The National Electrical Code (NEC) defines a hazardous location as “a location where fire hazards or explosion
hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust or ignitable fibers or
filings.

The Code further separates these hazardous locations into three classes:
Class I – locations containing gases and vapors
Class II – locations containing dust
Class III – locations containing fibers and filings.
Each of these classes is broken into divisions. These divisions are separated into groups according to

characteristics.

The following chart summarizes these classifications:

Class Division Group

I Gas 1 Hazard Exists – Always present A Acetylene

II Dust 1 Hazard Exists E Conductive and Combustible Metal Dust

III Fibers 1 Production Areas Combustible

1 in atmosphere B Hydrogen and Manufactured Gases containing Hydrogen

2 Potential Exists – May be present A Acetylene

1 in atmosphere B Hydrogen and Manufactured Gases containing Hydrogen

2 Potential Exists F Combustible Carbon Dust
