Electrical workers, regardless of experience, are faced with a major barrier when first introduced to NFPA 70E, “The Standard for Electrical Safety in the Workplace,” and an erroneous electrical safety culture pre-exists. This paper describes, from the author’s point of view, the barrier that he and other electrical workers have experienced and his insight into overcoming the barrier. The author in...
PPE exposed to arc flash is not always designed for arc flash exposures. This paper discusses the critical PPE rated for arc flash exposures for electrical workers and the test methods employed for those ratings. It also further explores other PPE which is frequently exposed to arc flash but which is not arc-rated. The purpose of the paper is to provide some guidelines on proper use and dangers posed...
PPE in the electric arc has been evolving since the early 1990's. With the introduction of OSHA Safety and Health Standards in the US and arc test methods in ASTM International, the growth of knowledge in PPE and proliferation of PPE for electric arc has grown throughout the world. In 1995, NFPA 70E began addressing arc flash boundaries and NESC added safety requirements for electrical safety. Misunderstandings...
Recent changes to some electrical safety standards, such as the NFPA-70E and CSA-Z462, have emphasized the need to look for improved safety compliance to mitigate the risks associated with the operation and maintenance of electrical equipment. Improved low voltage (LV) and medium voltage (MV) control equipment designs, including enhanced structural protection systems, have continued to evolve in support...
PPE in the electric arc has been evolving since the early 1990's. With the introduction of OSHA safety and health standards in the US and arc test methods in ASTM international, the growth of knowledge in PPE and proliferation of PPE for electric arc has grown throughout the world. Misunderstandings and errors in marketing still abound but knowledgeable users, manufacturers and researchers have helped...
Today, many engineering companies are faced with the engineering and designing of electrical systems in countries all around the world. The national electric grid and industrial distribution systems in these countries require the use of electrical equipment, with operating voltages that differ from those commonly used in the United States. Manufacturers must produce electrical products that are not...
