Electrical Shock Safety Criteria documents the proceedings of the First International Symposium on Electrical Shock Safety Criteria, held in Toronto, Canada, 7-9 September 1983. The objective was to establish the state of the art in the field of electrical shock safety criteria as applied to electrical power utilities. The symposium brought together leading experts from electrical utilities, universities, and research laboratories from around the world, interested in problems associated with electrical shock and safety. The proceedings are organized in three sections, each consisting of the morning review papers and afternoon panel discussions. Section 1 presents an in-depth analysis of the physiology of electrical shocks including such topics as body-weight scaling, electrocution equation, physiological effects of electrical current, and factors affecting fibrillation threshold. Section 2 focuses on the analysis of body impedance under various conditions and the techniques for measuring current distribution in the body. Section 3 is devoted to discussions of safety criteria and related standards from the point of view of current practices in electrical utilities.
