Today’s Webcast starts at 1:00 p.m. Eastern. You will not hear audio un=l the Webcast begins Today's Moderator Ron Kovach Managing Editor Today's Presenter Doug Tellin Project Manager, Electrical Safety Specialists A1er a rewarding 13 year career as a master electrician experienced in the installa;on and design of commercial/
industrial electrical systems and having the responsibility of overseeing many large electrical construc;on projects in the Kansas City area. Doug le1 his career as a master electrician in 2005 to follow his true passion in electrical safety. This is when he began working with electrical engineering firms developing electrical safety trainings, safety programs, and in charge of field opera;ons for arc flash hazard assessments. With experience involving over 1200 facili;es in North America and abroad, Doug has the exper;se needed to help companies become compliant with the complex standards and regula;ons in electrical safety. Learning Objec=ves:
•  Define the latest NFPA 70E and OSHA requirements as it pertains to electrical safety and electrical distribu;on •  Understand the differences between proac;ve and reac;ve safety, and which approach works best •  Evaluate the role of electrical maintenance in a building's overall electrical safety program To ask ques=ons: Please use the ques;on and answer panel on the right-­‐hand side of the screen, and send to all panelists. Polling Ques=on Today’s event will include a mul;ple-­‐choice polling ques;on. Your par;cipa;on is appreciated. Presenta=on Handouts All par;cipants will receive an e-­‐mail by the end of the day with a link to download a PDF copy of today’s presenta;on slides.

NFPA 70E and OSHA Have all set the bar high! OSHA NFPA 70E OSHA’S EXPECTATIONS •  Calcula;ng the poten;al fault current at each piece of equipment. •  Understanding overcurrent protec;ve devices and how they are coordinated for each circuit •  Crea;ng up-­‐to-­‐date one-­‐line electrical drawings. OSHA’S EXPECTATIONS •  This can be a very complex task for most facili;es. •  OSHA inspectors are trained to ask if these analyses were performed •  This is the only way for electrical hazards to be reduced to a manageable level. 130.5 Arc Flash Hazard Analysis An arc flash risk assessment be performed and shall: (1) Determine if an arc flash hazard exists. If an arc flash hazard exists, the risk assessment shall determine: a. Appropriate safety-­‐related work prac;ces b. The arc flash boundary c. The PPE to be used within the arc flash boundary 130.5 Arc Flash Hazard Analysis Be updated when a major modifica;on or renova;on takes place. It shall be reviewed periodically, at intervals not to exceed 5 years, to account for changes in the electrical distribu;on system that could affect the results of the arc flash risk assessment. The results of the arc flash risk assessment shall be documented. Ar=cle 130.5 (D) Equipment labeling Equipment Labeling. Electrical equipment …. shall be field-­‐marked with a label containing all the following informa;on: (1) Nominal system voltage (2) Arc flash boundary (Con;nue) Ar=cle 130.5 (D) Equipment labeling (Con;nued) (3) At least one of the following: a. Available incident energy and the corresponding working distance, or the arc flash PPE category in Table 130.7(C)(15)(A)(b) or 130.7(C)(15)(B) for the equipment, but not both b.

Leather footwear OSHA OSHA 1910.132 requires employers to: •  assess hazards •  select PPE •  Train employees on how to use it. OSHA 29 CFR 1910.301-­‐.399 requires: •  Lockout/tagout training. •  Electrical PPE •  Electrical safety training OSHA The latest revision of the OSHA defini;on for qualified person (1910.399 8/07) includes the phrase “has demonstrated skills.” To meet this requirement, the person has to actually demonstrate that he/she can perform the task. A dress rehearsal using appropriate PPE for the task will ensure that the employee can perform the task with the ligh;ng limita;ons of the flash suit hood and the dexterity limita;ons of voltage-­‐rated gloves with leather protectors. OSHA 1910.269(a)(2)(iii) Through regular supervision and inspec;ons conducted, at least annually, employers need to verify that each employee is complying with the safety-­‐
related work prac;ces. The employer must show proof of the appropriate training and cer;fica;ons for a person to be deemed qualified in OSHA’s Eyes. This is achieved by training, even for the experienced electrician. 110.2 Training Requirements (A) Safety Training. The training requirements contained in this sec;on shall apply to employees exposed to an electrical hazard when the risk associated with that hazard is not reduced to a safe level 110.2 Training Requirements Employees should be tested to demonstrate ability in performing the required tasks safely and in a =mely manner. If a reasonable person would conclude that the employer has not conveyed the training to employees in a manner or type they were capable of understanding, then the instruc;on or training has failed to meet the employer’s training obliga;ons and needs to be revised. Training should include formal presenta=ons and actual performance of the work under the supervision of knowledgeable persons. Some work tasks contain minimum exposure, and others expose workers to significant hazards. Todays Special Online swimming lessons only $9.95 42 110.2 Training Requirements. (C) Emergency Response Training.. •  (1) Contact Release. Employees exposed to shock •  hazards shall be trained in methods of safe release of vic;ms from contact with exposed energized electrical conductors or circuit parts. •  Refresher training shall occur annually. 110.2 Training Requirements. (C) Emergency Response Training.. •  First Aid, Emergency Response, and Resuscita=on. •  Employees responsible for responding to medical emergencies shall be trained in: –  First aid –  cardiopulmonary resuscita=on (CPR). Refresher training shall occur annually. –  automated external defibrillator (AED). Refresher training shall occur annually. 110.2 Training Requirements. (E) Training Documenta=on The employer shall document that each employee has received the training required by 110.2 (D). This documenta;on shall: • be made when the employee demonstrates proficiency in the work prac;ces involved • be maintained for the dura;on of the employee’s employment. • The documenta;on shall contain the content of the training, each employee’s name, and dates of training.
