Hazardous Locations Definition
A Hazardous Location is an explosive atmosphere due to the presence
of flammable gases, vapors, or liquids (Class I), combustible dusts (Class II) or
ignitable fibers & flyings (Class III).
An area may also be considered "hazardous" for other reasons, such as the use of
electrical equipment in the vicinity of water, the risk of personal injury from moving
or falling parts, or even the presence of biological hazards. While hazards are
associated with all of these conditions, areas are only considered hazardous
(classified) locations under conditions defined by the NEC, CEC, IEC 60079-10, or
CENELEC EN 60079-10, as applicable.
This approach to classifying hazardous locations is used by the United States
(National Electrical Code), Canada (Canadian Electrical Code), Europe
(CENELEC EN60079-10) and throughout the world (IEC 60079-10).
