ArcFlash – Loss Prevention “How to Get Started” 4-9-2014 for the Charlotte Regional Safety & Health School By: John Welch Section 1: Introduction Arc Flash Video Section 1: Introduction 1.1 Purpose of the Training Session To raise awareness about Electrical Safety and Arc Flash Prevention 5 to 10 people injured, 1 to 2 killed each day in arc flashes In 2007, OSHA mandated that companies SHALL protect against arc flashes Steps to “Provide a Safe Work Environment” Section 1: Introduction 1.2 Electrical Statistics Electrical Safety Statistics About 8,000 electrical contact injuries referred to emergency rooms annually in the United States. One person is electrocuted in the workplace each working day. Over 2,000 workers are sent to burn centers each year with electricalrelated burn injuries. Section 1: Introduction Section 1: Introduction 1.3 OSHA History OSHA – Occupational Safety and Health Administration Mission – “to assure the safety and health of America’s workers by setting and enforcing standards; providing training, outreach, and education; establishing partnerships; and encouraging continual improvement in workplace safety and health.” Fact – Since OSHA’s inception in 1971, nonfatal occupational injury and illness rates have dropped 60 percent, and occupational fatality rates have fallen to the lowest annual preliminary total since 1992 Section 1: Introduction 1.4 OSHA vs. NFPA OSHA is the “WHAT” NFPA is the “HOW” Section 2: OSHA 29 CFR 1910 2.1 OSHA’s Mission To assure the safety and health of U.S. workers OSHA sets and enforces safety standards Section 2: OSHA 29 CFR 1910 2.4 OSHA 29 CFR 1910.332 OSHA 29 CFR 1910.332 Qualified Person: “Those who have training in avoiding the electrical hazards of working on or near exposed energized parts.” This is a broad description for a qualified person. An electrical qualified person is more defined in the NFPA 70E Article 110.6 (D)(1) Section 2: OSHA 29 CFR 1910 2.4 OSHA 29 CFR 1910.332 Training: “The skills and techniques necessary to determine the nominal voltage of exposed live parts.” Section 2: OSHA 29 CFR 1910 2.7 OSHA 29 CFR 1910.333 (c)(2) Work on energized equipment: “Only qualified persons may work on electrical circuit parts or equipment that have not de-energized under the procedures of paragraph (b) of this section. Such persons shall be familiar with the proper use of special precautionary techniques, personal protective equipment, insulating and shielding materials, and insulated tools.” Section 3: NFPA 70E 3.2 NFPA Regulating Publications Application of Safety Related Work Practices Responsibility (NFPA 70E 105.3) The employer shall provide the safety related work practices and shall train the employee, who shall then implement them. Section 3: NFPA 70E 3.2 NFPA Regulating Publications NFPA 110.1 (C) 110.1 Relationships with contractors (outside service personnel, etc) (A)(2) The host employer shall report observed contract-employer-related violations of this standard to the contract employer. (B)(2) The contract employer shall ensure that each of his or her employees follows the work practices required by this standard and safetyrelated work rules required by the host employer. Section 3: NFPA 70E 3.2 NFPA Regulating Publications 110.1(C) Documentation There shall be a documented meeting between the host employer and the contract employer. Section 3: NFPA 70E 3.2 NFPA Regulating Publications 110.2 Training Requirements (C) Emergency Procedures Employees exposed to shock hazards and those employees responsible for taking action in case of emergency shall be trained in methods of release of victims from contact with exposed energized electrical conductors or circuit parts. Employees shall be regularly instructed in methods of first aid and emergency procedures, such as approved methods of resuscitation, if their duties warrant such training. Training of employees in approved methods of resuscitation, including cardiopulmonary resuscitation and automatic external defibrillator (AED) use, shall be certified by the employer annually. Section 3: NFPA 70E 3.3 Need to Know NFPA ARTICLE 130 130.2 Electrically Safe Working Conditions. Energized electrical conductors and circuit parts to which an employee might be exposed shall be put into an electrically safe work condition before an employee performs work if either of the following conditions exist: The employee is within the limited approach boundary. The employee interacts with equipment where conductors or circuit parts are not exposed, but an increased risk of injury from an exposure to an arc flash hazard exists. Section 3: NFPA 70E 3.3 Need to Know 130.2 (A) Energized Work 1) Greater Hazard – Energized work shall be permitted where the employer can demonstrate that de-energizing introduces additional hazards or increased risk. 2) Infeasibility – Energized work shall be permitted where the employer can demonstrate that the task to be performed is infeasible in a de-energized state 3) Less than 50V – Shall NOT be required to be de-energized Section 3: NFPA 70E 3.3 Need to Know NFPA 130.3 (A)(2) Energized electrical conductors and circuit partsUnsafe work condition. Only qualified persons shall be permitted to work on electrical conductors or circuit parts that have not been put into an electrically safe work condition. Section 3: NFPA 70E 3.3 Need to Know NFPA 130.4 Approach Boundaries to Energized Electrical Conductors or Circuit Parts (A) Shock Hazard Analysis A shock hazard analysis shall determine the voltage to which personnel will be exposed, the boundary requirements, and the PPE necessary in order to minimize the possibility of electric shock to personnel. Reference Table 130.4(C) (a)(b) NEW Table on: DC Approach Boundaries Section 3: NFPA 70E 3.3 Need to Know NFPA 130.5 Arc Flash Hazard Analysis Shall determine the arc flash boundary, the incident energy at the working distance and PPE within the arc flash boundary. Shall be updated when a major modification or renovations takes place. Shall be reviewed periodically, not to exceed 5 years. Section 3: NFPA 70E 3.3 Need to Know NFPA 130.5 (C) Equipment Labeling. Electrical equipment such as switchboards, panelboards, industrial control panels, meter socket enclosures, and motor control centers that are in other than dwelling units, and are likely to require examination, adjustment, servicing, or maintenance while energized, shall be field marked with a label containing all the following information: At least one of the following: Available incident energy and the corresponding working distance Minimum arc rating of clothing Required level of PPE Highest Hazard/Risk Category (HRC) for the equipment Nominal system voltage Arc flash boundary Section 3: NFPA 70E 3.3 Need to Know NFPA 130.6 (A) Alertness. When Hazardous >50V When Impaired Illness, fatigue Changes in Scope Additional hazards outside original scope (B) Blind Reaching.

Section 5: Arc Flash / Arc Blast 5.3 Arc Flash Is…Costly Over $250 billion in losses each year: Damage to Equipment Lawsuits Business disruptions OSHA citations Increased insurance Increased Experience Modification Rate (EMR) Bad public relations The ‘Band-Aid’ Approach Quick Fix Risk Management Gap 28 28 How to Get Started • Get Upper Management Support Building new Culture Only works Top Down You will have to purchase Arc Flash Study You will have to purchase PPE You will have to increase Training You don’t have to do it alone There are many Engineering Firms There are many Training Organizations There are few who can do all of it 29 How to Get Started • Perform an Arc Flash Study Sole Source to a Trusted Engineer RFP Process Provides The Risk assessment DATA • Use Data to align “Qualified” People The Energy Levels of your system get aligned with the resume’s on your team Deeming one “Qualified” is not easy, and the employee and employer have to be very clear on RISK (Top Down again) OPEN COMMUNICATION! 30 How to Get Started • Training in 70E Every Year!, Every 3 Year’s required NFPA changes every 3…hmm New Maintenance rules in 2015 Standard! • Document Arc Flash Program • It sits right next to your LOTO • Its custom to your system and your staff LOTO (Lockout/Tagout) This better be implemented already! • work experience/interpersonal skills It instills a positive culture, allow for healthy job briefings and will reduce your Electrical related Risks. 31 How to Get Started Example Subcontractor 1 Subcontractor 2 Subcontractor 3 John Smith Joe Albertson John Smith Joe Albertson Matt Kilpatric Greg Murphy Jeff Lunsoford John Smith Tom Hanks Joe Albertson Kent Smith Matt Kilpatric Greg Murphy Jeff Lunsford Mark Phillips Joe Curby Bill Murry 32 Arc Flash Loss Prevention Thank You!
