Download or read book Electrical Safety Code Manual written by Kimberley Keller and published by Butterworth-Heinemann. This book was released on 2010-07-19 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety in any workplace is extremely important. In the case of the electrical industry, safety is critical and the codes and regulations which determine safe practices are both diverse and complicated. Employers, electricians, electrical system designers, inspectors, engineers and architects must comply with safety standards listed in the National Electrical Code, OSHA and NFPA 70E. Unfortunately, the publications which list these safety requirements are written in very technically advanced terms and the average person has an extremely difficult time understanding exactly what they need to do to ensure safe installations and working environments. Electrical Safety Code Manual will tie together the various regulations and practices for electrical safety and translate these complicated standards into easy to understand terms. This will result in a publication that is a practical, if not essential, asset to not only designers and company owners but to the electricians who must put compliance requirements into action in the field. - Best-practice methods for accident prevention and electrical hazard avoidance - Current safety regulations, including new standards from OSHA, NEC, NESC, and NFPA - Information on low-, medium-, and high-voltage safety systems - Step-by-step guidelines on safety audits - Training program how-to's, from setup to rescue and first aid procedures
