8:00AM - Noon
|H. Landis “Lanny” Floyd II||Applying Power of Prevention through Design in Your Electrical Safety Program||Original presented at ESW2019 and updated for 2012, this tutorial will provide an overview presentation on ANSI/ASSE Z590.3 – 2011 Prevention through Design Guidelines for Addressing Occupational Hazards and Risks in Design and Redesign Processes. This standard provides guidance for a life-cycle assessment and design model that balances environmental and occupational safety and health goals over the life span of a facility, process, or product. After introducing the standard and reviewing the business case for prevention through design, the attendees will engage in a series of interactive working sessions to develop a hands-on practice to apply the standard to three scenarios essential to an effective electrical safety program.|

|Christopher Fink, Vincent H Leffler, and Mike Doherty||Construction Site Safety – Tools for Coordinating with All Trades||There is a multitude of knowledge levels required for safety best practices within the construction industry. Because there are so many unique hazards and risks involving electrical energy in the construction sector safety professionals, supervisors and managers often have significant misunderstandings as to the levels of risk and the risk controls that need to be implemented. All levels of the required expertise based on a few common themes will be discussed. This tutorial will assist the site safety professional, construction electricians and electrical safety professionals in understanding the challenges and barriers within a multi-traded construction job site. Innovative and leading edge ways to reduce the risks of electrical injuries within the construction sector.
How to educate and get construction contractors involved in day-to-day safety and the practical execution of effective tools such as auditing, quality tailgates, pre-job briefings, multi-generational awareness, and mitigation of the risks. In this tutorial we will discuss the rules, regulations, best practices, and some real world scenarios that have occurred within the presenters careers, and options for real world solutions to those items. An interactive workshop format will be utilized with significant participation by all to enhance cultural changes in the construction sector.

|Lloyd B. Gordon and Tommy R. Martinez||Risk Assessment for Electrical Work for All Electrical Hazards||This tutorial expands on progress in performing electrical risk assessment utilizing the 2021 NFPA 70E and the 2020 Department of Energy’s Electrical Safety Handbook, for all work environments, including utility, facility, and laboratory electrical work. It will present a simplified methodology to performing electrical risk assessment including electrical hazard identification, risk evaluation based on work task, equipment condition, work environment, and human performance factors. It will cover all injury mechanisms, including thermal, shock, and arc flash injury from ac and dc sources, as well as secondary hazards, such as electromagnetic fields, ionizing radiation, and mechanical hazards generated by electrical equipment. It will outline the process to incorporate risk control measures based on the hierarchy of controls. This methodology is applicable to facility and utility power systems, large battery systems found in transportation and energy storage systems, solar and wind power systems, DC transmission lines, lasers, accelerators, capacitor banks, electroplating systems, induction and dielectric heating systems, and high power inverter/rectifier systems.|

8:00AM - Noon
|Sergio Panetta and Ajit Bapat||System Grounding Methods for Petroleum and Chemical Facilities-|
Resistance Grounding Benefits
|This tutorial will provide an in-depth review and comparison of different grounding methods for system grounding of industrial and commercial electrical transformers and generators installed in facilities such as Petroleum and chemical manufacturing sites interested in safety and continuity of operation. The benefits of using high and low resistance grounding will be addressed. Calculating both High and Low impedance and understanding how and when to use each will be covered. Symmetrical components will be reviewed and a thorough understanding of how to calculate capacitive charging current to better understand the process to select a method of system grounding and sizing of resistor. How to convert existing grounding systems to high or low resistance grounding system will be also addressed.|

1:00PM - 4:00PM
|René Graves, H. Landis “Lanny” Floyd II, and Mike Doherty||Electrical Safety Management Tutorial||This tutorial will use ANSI Z10-2012, Occupational Safety & Health Managing Systems (harmonized with CSA Z1000) as the framework for bench-marking existing programs and for designing and implementing a state of the art electrical safety management system. It will show how the requirements of NFPA 70E, Standard for Workplace Electrical Safety (harmonized with CSA Z462) and other recognized industry standards can be aligned to achieve a comprehensive program based on proven safety management principles. The attendee will be provided the knowledge and tools to develop a business case to help enable management support, assess existing programs, identify improvement opportunities, and develop implementation plans.|

1:00PM - 4:00PM
|Mark Scott and Jeffrey A. Grovom||Capacitors - Principles and Application of NFPA 70E-2021 Annex R||This tutorial will use a combination of lecture and in-class exercises to guide attendees through the material of NFPA 70E-2021, Article 360 and Annex R, Working With Capacitors. Topics will include basic understanding of capacitor construction, stored energy hazards and thresholds, and calculation methods to quantify the hazards and wait times for discharge. It will teach the underlying principles behind the requirements and guide and incorporating step by step risk assessment procedures. At the end of the tutorial, attendees will be able to calculate capacitor stored energy and safe discharge times, assess relative risk, and select an appropriate set of controls to reduce risk to a tolerable level.|

1:00PM - 4:00PM
|Wes Mozely and Ayo Akinnikawe||Developing a Qualification Assessment||OSHA, the National Electrical Code®, and the NFPA 70E all contain a definition for qualified person. But how do we get beyond the definition and into the practical application of determining whether or not a person is qualified? Does completion of an apprenticeship program or a trade school render a person qualified? Does a license or other certification from the state or other authority having jurisdiction ensure that a person is qualified? This collaborative tutorial/workshop looks at the definition of the term ‘qualified’ and works with the attendee to develop documentation/assessments for what a qualified person looks like on their site. At the end of the workshop, the attendee will have documentation to take with them to serve as the foundation for their qualification assessment program.|

|Eric Stromberg and Jennifer Martin||Objectionable current. What is it? What are the causes, the effects, and the solutions?||Objectionable current is not defined in the National Electrical Code, but it is neutral current that flows on the 'grounding' system. Or, more specifically, the effective ground-fault current path. Before the mid 90s, the NEC had not clearly made a distinction between a separately derived system and a service. Because of this, many separately derived systems were installed as services and ended up with a system bonding jumper at the transformer location as well as the first disconnect. This created parallel paths for neutral current, which gave rise to magnetic fields in the building. Code panel 5 started really working on Article 250 in 2002 and by 2011 had cleaned up grounding issues, in the Code, that had existed for decades. That was only 10 years ago. Now, with all the sensitive electronic equipment present, what is the best path forward in understanding and addressing these issues?|
