Safety Basics Handbook - IDC-Online

1 BussmannSafety Basics Handbook for Electrical SafetySafety Basics (Bussmann Awareness of Safety Issues Campaign)This is an unproven compilation of technical materials that has been assembled by the developers for the benefit oftraining others about Electrical Safety , including electrical Arc-Flash hazards. It is being presented to illustrate thecritical nature of electrical Safety practices. While not the only method(s) or answer(s), or perhaps not even the bestmethod(s) or answer(s), in the opinion of the developers/presenters the content is an accurate, acceptable, and positiveway to present the subject material.

2 The National Fire Protection Association s NFPA 70E - 2000 introduces safe workpractices to mitigate the flash hazards identified by this work. By creating awareness of the potential hazards anddescribing workable solutions by which the hazards can be controlled, minimized or eliminated, it is hoped that injury willbe reduced and lives will be of the information contained in the Safety Basics program material is at your own seeking permission to reproduce portions of this document must contact Cooper Bussmann, Inc. for appropriate license.

Jones PE with Electrical Safety Consulting Services, Inc.,(ESCS, Inc.) who provided consultation services for the Safety Basics program is a professional engineer with more than 35 years of experience in developing andoperating electrical Safety systems and processes in industrial units. Ray retired from theDuPont Company in 1998 where he held the position of Principal Consultant, concentrat-ing on electrical Safety systems and processes as well as codes and standards. Ray isactive in multiple technical committees for NFPA, including NFPA 70E, which covers elec-trical Safety requirements for employee workplaces.

6 62I. IntroductionAn increasing number of organizations are actively promoting electrical Safety foremployees. For example, the National Fire Protection Association NFPA 70E Standard for Electrical Safety Requirements for Employee Workplaces has beencompletely updated. The Institute of Electrical and Electronics Engineers (IEEE) justpublished a new Yellow Book, the IEEE Guide for Operation, Maintenance andSafety of industrial & Commercial Power Systems. The University of ChicagoTrauma Center has a new unit specializing in electrical burns and related interests are not only on improving treatment methods, but also providing moreinsight of electrical injuries and awareness on how to avoid electrical hazards.

7 Majormanufacturers and entire industries are seeing benefits of becoming more involvedin promoting employee Safety awareness programs. The purpose of this Safety Basics Handbook is to: provide increased awareness of Safety issues faced by individuals who workon or near electrical equipment, as well as system operators and equipmentdesigners/specifiers and to provide Safety principles to be used for protecting individuals frompotential injuries and even death caused by electrical material is designed to provide the reader with an overview of hazards associat-ed with exposure to electrical energy.

8 It will highlight standards and standard organi-zations, and offer guidance on Safety procedures and a number of key principles thatwill help to minimize exposure to electrical hazards. Knowing how to minimize theexposure to electrical hazards will help to reduce future injuries and even Safety Basics program is for the supervisor, manager, electrician, engineer,and the designer/specifier of equipment used in the electrical system. The IEEE makes it very clear that, Engineers engaged in the design and operation of electricalsystems protection should familiarize themselves with the most recent OSHA regula-tions and all other applicable regulations related to human Safety .

9 To the IEEE,providing adequate Safety means going beyond the minimum requirements fromconsensus standards. Perhaps a statement in the IEEE Buff Book says it best - Safety has priorityoverservice continuity, equipment damage or economics. BussmannSafety Basics 1II. Consensus StandardsConsensus standards are seen as the generally accepted engineering practices andcan be used for litigation purposes when entered as evidence in a legal case of an accident, where litigation is involved, the design and Safety practicesused will be compared with these standards.

10 In some cases this type of enforce-ment is more critical than if the government were the enforcing agent. In the United States, consensus standards are normally written by volunteers andpublished by standards developing organizations (SDOs). The content of consensusstandards is the result of a blue-ribbon panel of experts and defines the industry sbest generally available knowledge. Consensus standards fall into several differentclasses. Some consensus standards are product oriented; others define testingrequirements, cover installation or design issues, or are people oriented.
