This could be a Near Miss Incident, an OSHA Recordable incident, a Disabling Injury, or a Fatality. Any one of them can cause a major shift in company culture and how we look at electrical safety This paper is a case history review of a major Disabling Near Fatality event that happened very early in the author's career as a Maintenance Engineering Supervisor. The incident involved an electrician who stuck his bare hand into an energized 13.8 kV breaker bushing that nearly killed him. This incident has had a profound impact on the author's electrical safety thinking. The paper is not being written with the intent for the reader to answer the author's question. It is being written with the intent that each reader examines his own career for a serious incident and asks himself: “What Could I Have Done Differently?”","PeriodicalId":297284,"journal":{"name":"2019 IEEE IAS Electrical Safety Workshop (ESW)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124499171","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}

{"title":"Implementing Improvements in Hazard Identification and Barrier Implementation as a Corrective Action for a Serious Electrical Contact Incident","authors":"S. Jackson","doi":"10.1109/ESW41045.2019.9024748","DOIUrl":"https://doi.org/10.1109/ESW41045.2019.9024748","url":null,"abstract":"In 2014 a British Columbia Hydro electrician made inadvertent hand contact with a 12kV bus while working on a station disconnect switch installation. The electrician lived but ended up losing both arms below the elbows. This paper steps through the incident, the two and a half month investigation, and the corrective action implementation of improving hazard identification and effective barrier implementation as part of job planning. The paper will briefly introduce the Tripod Beta methodology of incident analysis which focuses on barriers that could have been implemented to prevent or mitigate the outcome. The paper will reveal how human factors contributed to the incident as well as how a very detailed and thorough tailboard discussion focused on generic hazard categories rather than specific hazard sources. The corrective action implementation included introducing a barrier effectiveness tool called the Hazard Barrier Reference that crews now use as part of their tailboard process. If crews cannot implement at least one effective barrier from the Hazard Barrier Reference sheet then that triggers a Hazard Barrier Deficiency process that logs the work situation in a registry. A Hazard Barrier Governance Committee was formed to address these deficiencies and look for barrier improvements.","PeriodicalId":297284,"journal":{"name":"2019 IEEE IAS Electrical Safety Workshop (ESW)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130146384","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 regulatory requirements will be discussed including OSHA, NESC, and others, to get an understanding of how utilities consider HV Arc Flash. Furthermore, the methods for evaluating high voltage arc flash, key driving factors, and rule of thumbs, and HVAF personal protective equipment will be discussed and compared in great detail to aid in the selection of a thermal incident energy evaluation method. The paper includes an example application of High Voltage Arc Flash Assessment using various commercially-available software. This example illustrates the importance of performing a HV Arc Flash Assessment for utility applications and highlight the differences between thermal incident energy evaluation methods and how they can be conservatively applied for situations outside their intended application range.","PeriodicalId":297284,"journal":{"name":"2019 IEEE IAS Electrical Safety Workshop (ESW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130109924","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}

How many leaders in today's multi-generational workplace have been effective at accepting this challenge and driving change? Under the IEEE IAS Electrical Safety Workshop mission statement of “Advancing the Electrical Safety Culture,” safety leaders are being tasked with finding new ways to change and advance the culture in a period when many companies are looking to technology to help them gain the innovative advantage. Clear and effective communication amongst all generations is the key to advancing electrical safety. Safety professionals and workers alike must rise to this challenge by looking first at their own styles of communication, communication of their coworkers and peers, and then by working closely together to effectively and clearly communicate electrical safety.","PeriodicalId":297284,"journal":{"name":"2019 IEEE IAS Electrical Safety Workshop (ESW)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132013917","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}

However, once the problem is determined, troubleshooting often segues right into repair and we find our craft performing repairs with equipment still in an energized state without an Energized Electrical Work Permit in place. Even more concerning than the lack of a properly executed Energized Electrical Work Permit is the fact that the repair work may not need to be performed in an energized state at all and an electrically safe work condition can be established before repairs begin. This paper discusses where to draw the line between troubleshooting and “working on” and provides suggestions for methodologies to better identify for the craftsman when the work has transitioned from troubleshooting to repair and de-energization of the equipment or implementation of the Energized Electrical Work Permit process is required.","PeriodicalId":297284,"journal":{"name":"2019 IEEE IAS Electrical Safety Workshop (ESW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133151062","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}

Maberry","doi":"10.1109/esw41045.2019.9024717","DOIUrl":"https://doi.org/10.1109/esw41045.2019.9024717","url":null,"abstract":"The activities of an electrical worker are often construed as overly complex or challenging and are often misunderstood by most non-electrical workers. Non-electrical workers may not understand what they do not know and risk greater exposure to electrical events because of it. Recognition of this was the first step in what amounted to a three-year, multi-tiered journey by the authors and their former colleagues to utilize the NFPA 70E standard to create and implement an effective and sustainable electrical safety program (ESP) at a large petrochemical company. We began by identifying our problems through third-party auditing of our programs which led to an actionable task list. This task list was then split up and targeted by department: the qualified electrical workers (QEWs) within the refineries, the operations employees interacting with the equipment and the QEWs, and the contractor workforce assisting them both. Programs were developed to encompass the tasks of each department, whether it be assisting, operating, or performing work on electrical equipment. Program creation, revision, and updating were conducted by a cross-discipline task force consisting of individuals from operations, health and safety, engineering and both maintenance electricians and power distribution. Training, utilizing a third-party vendor, was designed specifically to encompass NFPA 70E and how we, as an organization, have implemented it, through both procedure and practice, for each targeted department. This instructor led training was provided to the entirety of the operations and maintenance groups. After beginning the process in the first quarter of 2015, full implementation of the 2018 version of NFPA 70E occurred in December 2017, and we have now moved into sustainability of the program. As a result, we expect to see a reduction in electrical incidents, and most notably, have seen an increase in the cross-discipline knowledge of electrical safe work practices allowing us to become more inquisitive, and assist in further developing our people, programs, and most importantly our culture, around electrical safety.","PeriodicalId":297284,"journal":{"name":"2019 IEEE IAS Electrical Safety Workshop (ESW)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117266227","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}

In certain cases, addition of fuses that are rated significantly above the circuit breaker trip value in series with the circuit breaker can reduce the arc flash potential significantly. These fuses do not significantly affect the trip coordination of the system, since they will only actuate when there is a severe fault, such as a bolted short circuit fault or a fault sufficiently severe as to present an arc flash hazard. This paper examines an applicable case, using trip curves to analyze the arc flash potential, and reducing arc flash from above 15 cal/cm2 to below 1.2 cal/cm2 by addition of fuses.","PeriodicalId":297284,"journal":{"name":"2019 IEEE IAS Electrical Safety Workshop (ESW)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123433904","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}
