The safety management system, Integrated Safety Management (ISM) is a formal and proven system for the safe execution of work activities. ISM can be implemented into a work control process and can structure an electrical safety program through its Guiding Principles and Core Functions. An electrical safety work control process has two components which need to be implemented for success, an NFPA 70E based electrical safety program and ISM based work control process. An electrical safety program which implements the ISM seven Guiding Principles and five Core Functions gives a well-defined and document supported process to keep workers safe. The Guiding Principles are: 1. Line Management Responsibility for Safety, 2. Clear Roles and Responsibilities, 3. Competence commensurate with Responsibilities, 4.Balanced Priorities, 5. Identification of Safety Standards and Requirements, 6. Hazard Controls Tailored to Work Being Performed 7.Operations Authorization. The core functions are: 1. Define the Scope of Work, 2. Analyze the Hazards, 3. Develop and Implement Hazard Controls, 4. Perform Work within Controls, 5. Provide Feedback and Continuous Improvement. An electrical safety program which implements a work control process based on ISM endorses the employees as active participates in the process and gives the workers ownership in their safety.","PeriodicalId":185723,"journal":{"name":"2016 IEEE IAS Electrical Safety Workshop (ESW)","volume":"379 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134543951","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 effectiveness of current limiting fuses is reinforced by their inclusion in NFPA 70E-2015: Note to Table 130.7(C)(15)(A)(b), Annex D.4.6, and Annex O.2.4(4). The incident energy levels associated with current limiting fuses can be determined from IEEE Standard 1584-2002, IEEE Guide for Performing Arc-Flash Hazard Calculations. IEEE 1584-2002 presents a method for directly determining incident energy without first determining arc current or arc duration. The fuse equations were derived from 600V arc tests involving a range of current limiting fuse sizes. This data is reviewed to assess the performance of current limiting fuses in reducing arc energy in accordance with the proposed NFPA 70-2017 Section 240.67. The IEEE 1584-2002 equations are used to assess the performance of these fuses in comparison with an arc energy reduction maintenance switch, and the combination of both technologies. The viability of predicting arc current and incident energy for installations involving current limiting fuses and implementing the proposed NEC Section 240.67 using general arc models is discussed.","PeriodicalId":185723,"journal":{"name":"2016 IEEE IAS Electrical Safety Workshop (ESW)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127003521","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}

One method is to reduce the duration of the arc flash by using protective relays to sense an arc flash fault. This method requires a supply-side overcurrent protective device that will respond to the protective relaying fast enough to mitigate the incident energy. In many existing installations, MV transformer primary fuses are already installed to provide transformer protection. Before the development of a MV controllable fuse, the MV fuse would have to be replaced with a MV circuit breaker or circuit switcher to have relay control of the MV protective device. This replacement would have significant equipment/construction costs and would require extensive equipment outage time. The MV controllable fuse method uses the existing fusegear protecting the primary side of the transformer. The protective relaying senses the arc fault and signals the controllable fuse to change to a faster acting time-current response. Incident energies can be reduced from 200 Cal/cm2 to below 8 Cal/cm2 on the transformer secondary. This paper reviews an installation using a MV controllable fuse to mitigate the incident energy on the equipment connected to the transformer secondary.","PeriodicalId":185723,"journal":{"name":"2016 IEEE IAS Electrical Safety Workshop (ESW)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129639394","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 can result in a significant reduction in arc-flash incident energy levels. The reduced incident energy levels also have the benefit of substantially reducing damage to the switchgear equipment. This paper includes a field report of an actual arc-flash trip event, demonstrating how AFD technology performs in realworld conditions. We will contrast this field report to the outcome described in the ESW paper, “The $125,000 Field Mouse” [1]. In our incident, a rat entered the switchgear outgoing cable compartment, and came in contact with the cable terminals, resulting in an arc fault. The AFD relay's waveform capture (oscillography) report shows that the arcflash detection element in the relay detected the arc flash and performed an immediate trip of the feeder breaker. Instead of the $125,000 damage cited in the previous paper, this switchgear suffered only minor damage and a brief outage. These field reports show that AFD technology performs as expected in reducing arc-flash hazards.","PeriodicalId":185723,"journal":{"name":"2016 IEEE IAS Electrical Safety Workshop (ESW)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129376258","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 electrical hazards of shock, electrocution, arc flash, and arc blast are universal to these systems, therefore employers, along with their employees who operate and maintain or otherwise interact with, electrical power systems and equipment, must have a clear understanding of the hazards and what they need to do for their safety. Electricity is no respecter of persons; it will injure or kill a custodian, laborer, supervisor, or office worker just as fast as it will injure or kill an electrician. All electrical power systems and equipment must be assessed to determine which of the electrical hazards exist or may exist, in order to develop an effective electrical safety program, safe work procedures, training for qualified and unqualified personnel, and PPE requirements.

The testing was done using: a) “open air” apparatus for fabric panel test methods ASTM F1959 and IEC 61482-1-1 with vertical butted arc electrodes in open air; b) “box” apparatus for test method IEC 61482-1-2 with vertical butted arc electrodes placed in a box; c) nonstandard “ejected arc” apparatus with parallel horizontal arc electrodes in open air. FR treated Cotton fabric was used to evaluate the difference of protective properties for the three geometries and arc current levels of 2, 4, 8, 12, and 16 kilo amperes for each of geometries (as possible). Distance between fabric and arc electrodes was 18 inches and an arc gap was 12 inches except box test. A strong difference of a second degree skin burn threshold for tested FR fabric was demonstrated among different geometries and upon current level within the same geometry. Inverse power function represents Time-Current Curve (TCC) second degree skin burn threshold for the fabric. Knowledge of electrode configuration is required and has to be taken in consideration for proper electric arc protection. ATPV alone does not provide adequate protective for all arc configurations.","PeriodicalId":185723,"journal":{"name":"2016 IEEE IAS Electrical Safety Workshop (ESW)","volume":"16 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114014141","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}
