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.

Recipient of the 2014 International Association for Relationship Researchers Book Award! This multidisciplinary text highlights the development of romantic relationships, from initiation to commitment or demise, by highlighting the historical context, current research and theory, and diversity of patterns.  Engagingly written with colorful examples, the authors examine the joy, stress, power-struggles, intimacy, and aggression that characterize these relationships. Readers gain a better understanding as to why, even after the pain and suffering associated with a breakup, most of us go right back out and start again. Relationships are examined through an interdisciplinary lens –psychological, sociological, environmental and communicative perspectives are all considered. End of chapter summaries, lists of key concepts, and additional readings serve as a review. As a whole the book explores what precipitates success or failure of these relationships and how this has changed over time. Highlights of the book’s coverage:Incorporates both cross-sex and same-sex romantic relationshipsExamines the roles of gender, race, class, culture, age, and sexuality in relationship developmentLooks at multiple types of romantic relationships in emerging adulthood, including dating and cohabitationExplores both positive and negative relational processesAnalyzes the latest and most important scholarship. The book opens with an introduction followed by a historical overview of the development of relationships. Next relationship development models are examined including the influence of social factors and the interaction of the partners involved.  This volume examines how partners initiate romantic relationships, including infatuation, sexual attraction, and the impact of technology; how cohabitation affects the quality of the future of the relationship; and  the individual, social, and circumstantial factors that predict stability or break-ups in romantic relationships.  The book ends with an examination of the “dark side” of relationships, and suggestions for future research on romantic pairings. Intended as a supplement for advanced undergraduate or graduate courses in marriage and family, personal/close/intimate relationships, or interpersonal/family communication taught in human development and family studies, psychology, social work, sociology, communication, counseling and therapy, this book also appeals to researchers and practitioners interested in the romantic relationship processes.
