2. 2. Definitions Documentation Training Program Audits Hazard/RiskCategory Tables DC System Hazards
3. 3. Arc-rated (AR) Previously flame resistant (FR) Reported in ATPV or EBT AR is FR, but FR is not AR Informationalnote Previously fine print note Incident energy analysis Arc flash protection boundary
4. 4. Approach Boundaries ReviewAny point on an exposed,energized electricalconductor or circuit partProhibited approach boundaryRestricted approach boundary Limited approach boundary Arc Flash Boundary
5. 5. Relationships with Contractors Article 110.1(C) Required meeting between host employer andexternal contractor Must be documented
6. 6. Training Requirements for Emergencies Article 110.2(C) Automatic external defibrillator (AED) training shall be certified by the employer annually
7. 7. Training Requirements for Employees Article 110.2 Employer must determine employee compliancewith this standard annually Employee retraining every 3 years Employer must retain description of content
8. 8. Electrical Safety Auditing Article 110.3(H) Audit of employers electrical safety program Including field work Frequency must not exceed 3 years Must be documented
9. 9. Electrically Safe Working Conditions, Article 130.2(A) Rearrangement of the article may require equipmentto be de-energized more often Within the Limited Approach Boundary (LAB) Equipment interaction with increased risk Energized work permit, Article 130.2(B) Diagnostics work exemptions still apply
10. 10. ArcFlash Hazard Analysis 2009 Article 130.3, Exception No. 1 Allowed exception to AFHA for certain systems less than 240 volts supplied by small transformer Rescindedin 2012 Article 130.5, Informational Note No. 5 Refer to IEEE 1584 for three-phase systems rated less than 240 volts
11. 11. DCShock Protection Boundaries Article 130.4(C)(a) Similar in format to the AC boundaries Minimum voltage addressed is 100 VDC
12. 12. AFHAEquipment Labeling Article 130.5(C) Equipment likely to require maintenance, servicing,adjustments while energized shall be field markedwith a label
13. 13. AFHAEquipment Labeling Article 130.5(C) The labels have to include the following three lines 1)At least one of the following a. Available incident energy and the working distance or b. Minimum arc rating of clothing or c. Required level of PPE or d. Highest Hazard/Risk Category (HRC) 2) Nominal system voltage 3) Arc flash boundary
14. 14. AFHAEquipment Labeling Article 130.5(C) ONE EXCEPTION: Labels applied prior to September30, 2011 and when they contain available incident energy or required level of personal protective equipment
15. 15. Personal Protective Equipment Article 130.7(C) Hearing Protection AR Clothing Systems Head Protection Modified Hand Protection
16. 16. HazardRisk Categories (AC Voltages) Table 130.7(C)(15)(a) Conditions were moved into the tables Descriptions now include arc flash boundaries HRC2* removed and replaced by HRC2
17. 17. HazardRisk Categories (DC Voltages) Table 130.7(C)(15)(b) Similar in format to the AC equipment table Based on energized work and arcing currents Maximum voltage range is 1000 VDC
18. 18. Safety Related Maintenance Article 205 Single line diagrams must be current and legible Equipment must be maintained IAWmanufacturers instructions Maintenance, tests and inspections of overcurrentdevices must be documented.
19. 19. HazardAnalysis, Risk Estimation and Risk Evaluation Procedure - Annex F Provides a model for evaluating hazards Identifies hazards and assess risks Completed prior to starting work
20. 20. Public comments closed 6/22/13 Definition of Qualified Person Risk Assessment Procedures Emergency response Focus on training/retraining documentation Deletion of PPE Category 0 Yes/No tables for arc flash hazards Technical Committee draft due 2/8/13
