IntroductionHazardous locations are those areas where a potential for explosion and fire exists due to the presence of flammable gases, vapors, pulverized dusts or ignitable fibers in the atmo-sphere. Hazardous locations are created from the normal pro-cessing of volatile chemicals, gases, coal, grains, etc., or from the accidental failure of storage systems for these materials.
Open flames are not permitted in these locations. The use of electric heating equipment is permitted with two major restric-tions: 1) The surface temperature of the equipment cannot exceed the ignition temperature of the hazardous atmosphere and 2) all arc and spark producing devices must be isolated from the atmosphere in an appropriate enclosure.
Both people and equipment in hazardous locations can be heated safely and economically with electric heat. Electric heating is typically much less expensive to install and maintain than caparable remote oil or gas fired heating systems.
National Electrical Code ClassificationArticles 500 through 516 of the National Electrical Code deal with the definition of hazardous areas and the use or design of electrical equipment used in these locations. Electric heating equipment for hazardous areas is specified based on the NEC class, division, group and ignition temperature or the alter-nate class and zone classification.
ClassHazardous locations are divided into the three general classes of vapors/gases, dusts and fibers.
Class I Locations where the potential for explosion and fire exists due to the presence of flammable gases or vapors in the air. Typical Class I locations include oil or natural gas drilling rigs, petroleum refining or pumping facilities, petro-chemical plants, wastewater/sewage treatment plants, solvent extraction plants, paint spraying booths, locations where open tanks or vats of combustible liquids are present and storage areas for flammable materials.
Class II Locations where the potential for explosion exists because of finely pulverized flammable dusts suspended in the atmosphere. Typical locations would include coal fired power plants, coal preparation/coal handling facilities, coal mines, grain elevators, flour and feed mills, packaging and han-dling of pulverized sugar and processing and storage of mag-nesium and aluminum powder.
Class III This third classification is primarily a fire hazard where fibers or flyings suspended in the air create a hazard. This would include small pieces of thread-like fiber, sawdust, lint, etc. Typical applications would include textile mills, wood-working plants, cotton gins, cotton seed mills and flax produc-ing plants.
DivisionClass I, Class II and Class III areas are further defined in terms of when the hazard occurs. Division 1 and Division 2 occur-rences are summarized below.
Division 1 If the hazard is expected to be present under normal conditions, such as a production or processing facil-ity, the occurrence is designated Division 1. The hazardous atmosphere may be present continuously, intermittently, peri-odically, or during normal repair or maintenance operations. Division 1 occurrences also include locations where a break-down in the operation of processing equipment results in the release of hazardous vapors.
Division 2 If the hazardous material is normally expected to be contained within a closed area, system or container, and would enter the ambient atmosphere only under an abnormal failure, then it is referred
