Installation, operation and maintenance considerations for electrical equipment in hazardous locations

Industrial electrical systems require proper installation, operation and maintenance of equipment for a facility to operate safely and efficiently. Of the many types of electrical installations, those in hazardous areas are likely the most difficult to deal with. Misunderstanding or misinterpretations can easily lead to unsafe conditions that put personnel and facilities at risk. This presentation discusses the critical elements for maintaining various types of hazardous location equipment. Class I, Divisions 1 & 2 and Class I, Zones 0, 1, & 2 concepts will be discussed. Class II and Class III hazardous locations are not addressed in this paper.
