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 and errors in marketing still abound but knowledgeable users, manufacturers and researchers have helped make materials more comfortable, protective and available for many more work situations. OSHA 1910.269 in 1994, NESC in 2007, NFPA 70E in 2000, 2004 and 2009 and now CSA Z462 have codified clothing for electric arc. Brazil, Peru, Russia, recently South Africa, New Zealand, and Australia are codifying laws related to arc flash PPE so the international focus is critical.","PeriodicalId":174139,"journal":{"name":"2010 IEEE IAS Electrical Safety Workshop","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114934275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This task would seem simple with currently available standards and reference materials. However the journey to a simple practical program that can be utilized directly by the worker is not necessarily obvious. The largest hurdle with respect to creation of such a program is risk management. It is possible to streamline current standards and practices to produce a corporate safety program. This can be accomplished by examination of the work tasks and the associated risk. A zero risk scenario is not possible as such a balanced approach that is rational and practical should be utilized.","PeriodicalId":174139,"journal":{"name":"2010 IEEE IAS Electrical Safety Workshop","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130282420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research suggests that lower arcing currents could lead to longer clearing time of protective devices and higher incident energies. Additional research also suggests that Flame-Resistant (FR) material used in electrical Personal Protective Equipment (PPE) may not provide the same protection levels as predicted by their arc rating when placed within these convective flows. The possible impact on protection requirements, work procedures and mitigation strategies of these findings is discussed. This paper looks at the impact of adjusting the Cf factor of the IEEE 1584 incident energy equation to accommodate test data from alternate configuration, using lower IARC and de-rating the arc rating of PPE.","PeriodicalId":174139,"journal":{"name":"2010 IEEE IAS Electrical Safety Workshop","volume":"12 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126037329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The National Fire Protection Association's, (NFPA 70 & NFPA 70E, American National Standards Institute's (ANSI C2), and similar standards by Nationally and Internationally recognized standards developing entities, place minimum requirements on electrical system designers and manufacturers that yield functional, practical and reasonably safe electrical installations. There is a need to capture in one location the wealth of electrical system design techniques that have been published in recent IEEE papers and in other industry sources. There is a need to educate the electrical engineer, design professional and the project manager about the available options to improve electrical safety while designs are still on paper. A new IEEE Working Group to develop an “IEEE Recommended Practice for Electrical System Design Techniques to Improve Electrical Safety” is being assembled. It will be working to bridge the gap between practical code requirements and zero injuries. The Officers of this Working Group will detail the need for this new IEEE document, the challenges that the Working Group faces, and appeal for additional assistance in this rewarding effort.","PeriodicalId":174139,"journal":{"name":"2010 IEEE IAS Electrical Safety Workshop","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115080619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
