Classification of Hazardous Areas
Hazardous areas are classified considering the presence and duration of potentially explosive atmospheres caused by flammable gases, vapors, dust, or combustible fibers. These classifications warrant that suitable safety measures may be appropriately taken to mitigate the existing risk. The two principal systems used for classification are the International Electrotechnical Commission (IEC) system and the National Electrical Code (NEC) system.
IEC Classification System
This system designates hazardous zones as:
| Zone | Description | Risk Level |
|---|---|---|
| Zone 0 | An area where an explosive atmosphere is present continuously or for long periods | Highest Risk |
| Zone 1 | An area where an explosive atmosphere is likely to occur during normal operations | High Risk |
| Zone 2 | An area where an explosive atmosphere is unlikely to occur but may occur for short durations under abnormal circumstances | Moderate Risk |
NEC Classification System
This Uses Classes, Divisions, and Groups:
- Class I: Areas with flammable gases or vapors
- Class II: Areas with combustible dust
- Class III: Areas with ignitable fibers or flying
Considering that Class I encompasses flammable materials, a distinction between Division 1 and Division 2 exists. Division 1 covers situations wherein explosive atmospheres are common under normal operations; Division 2 extends to situations wherein such atmospheres are abnormal or unusual.
Groups – Specific substances are further divided into Groups (e.g., Groups A-D for gases within Class I and E-G for dust within Class II), so that safety measures can be tailor-made.
The very stringent guidelines that are made according to these classifications band the design, installation, and maintenance of equipment so as not to become a source of ignition, all towards ensuring operational safety in hazardous locations and compliance therewith.
