Book Description
The Third Edition of this best-selling text continues to familiarize electricians with the intricate details of performing electrical installations in hazardous locations. Intended to serve as a general reference on the classes, groups, and divisions of hazardous locations, the text provides users with a comprehensive introduction to what hazardous locations are and are not, before progressing to more complex topics such as the requirements for equipment protection systems, protection against ignition from static electricity and lightning, and NEC? compliance. Completely updated, Electrical Installations in Hazardous Locations, Third Edition now includes information on the availability of new technology, as well as the latest national and international codes and standards.

Book Description
How to prevent electrical hazards in the workplace is the focus of this guide. It spells out proper design, maintenance, and operating procedures for minimizing the risks of electrical fires, accidents, and injuries on the job. Coverage of the latest electrical standards helps you comply with the current National Electrical Code (NEC)?? and OSHA requirements. NEC requirements and procedures are provided for grounding an electrical distribution system, selecting proper conductors, sizing the feeder, and effective branch circuit overcurrent protection. Safety considerations are explored for single and three-phase systems, fuses, plugs, and ground fault circuit interrupters (GFCIs). The guide also clarifies factors that influence soil resistivity, and it analyzes correction factors for special situations such as high ambient temperature environments. Human responses to electric shock are covered in detail. Among the important areas addressed are the approximate electrical impedance of the human body, thresholds of shock perception, let-go currents, asphyxia, ventricular fibrillation, and respiratory arrest. A bounty of solutions to help you solve electrical safety problems related to: * Hazardous locations -- Find out how to assess potential ignition sources, ventilation requirements, surface temperature conditions, and conduit and cable sealing requirements. * Current-carrying conductors in fire environments -- See how to evaluate insulation behavior, conductor melting temperatures, and the effects of nicks and broken strands, as well as how to make investigations at the scene of a fire. * Lightning protection -- Equip yourself to determine the probability of lightning strikes in specific locations, and mitigate the effects of a direct strike on buildings, equipment, and personnel. How to provide voltage surge protection is also discussed. * Static electricity -- Learn about the fundamentals of electrical charge induction and mechanisms for static charge ignition. Numerous case histories provide valuable insights into accident provention. In addition, the guide provides a review of electricity basics ranging from definitions of terms to the physics of the electric arc. It provides full-scope coverage of all electrical safety issues in the workplace. Electrical Hazards and Accidents: Their Cause and Prevention is an essential source for facility engineers, electrical engineers, plant engineers, plant managers, electricians, regulatory managers, and accident and insurance investigators.
