Impact of Changes to IEEE 1584 Guide for Performing Arc-Flash Calculations

Speaker: Steve Park, Vertiv’s Electrical Reliability Services and High Voltage Maintenance

Description:
In the 2018 update to IEEE 1584, radical changes were made to the calculation of arcing current, incident energy, and arc-flash boundary. These changes affect the previously calculated results and arc rated PPE recommendations made based on the previous 2002 edition of this guide. This presentation will address the most important areas of impact and considerations for updating arc-flash hazard analysis studies.

  1. What is IEEE 1585?
  2. Brief history of arc-flash analysis.
  3. Major changes in IEEE 1584.
  4. Impact of changes to calculated values (arcing current, incident energy, arc-flash boundary).

10:30 AM–11:15 AM
Personal Protective Grounding – Are We Protecting Ourselves?

Speaker: Alan Andrew Holt, Premier Power Maintenance Corporation

Description:
Personal protective grounding is part of our daily life.  This vital portion of our safety plan is the final step for electrical contact safety following:

  1. Personal verification of equipment to be worked on and energy sources for the equipment.
  2. Proper isolation of all energy sources
  3. Appropriate lock-out-tag-out
  4. Verification by approved electrical testing equipment is de-energized

Industry standards to follow that include:

  1. NFPA70E 120.5 Process of Establishing and Verifying an Electrically Safe Work Condition
  2. OSHA 1910.269(n) Grounding for the Protection of Employees
  3. ASTM F855 Standard Specification for Temporary Protective Grounds

While personal protective grounds are the final step to creating an electrically safe work condition, there have been technicians that have approached the placement of grounds in less than an effective manner.  Some individuals may view the application of safety grounds merely as a check-list item rather than assuring personal safety by the use of proper personal protective grounding techniques. This paper will review the existing standards and industry best practices, perform personal protective ground review on job sites, and provide recommendations for improved safety in the workplace by utilizing appropriate and effective safety grounding methods.

11:30 AM–12:15 PM
Complacency or Comfortability? What is your Company Doing to Prevent Complacency?

Speaker: Kenneth George Peterson, Hampton Tedder Technical Services

Description:
During my career, I have witnessed long-term experienced employees fail to follow the best practices, policies, and procedures due to becoming complacent and comfortable. In our industry, it is in our best interest to put experienced, trained, and qualified people in the field. However, over time, I have witnessed crews become familiar with their peer work practices and reduce the in-depth discussion of routine tasks, roles, and responsibilities. In this paper, I will discuss three separate events of seasoned veteran crews working together that had fallen into comfortability and led to complacency as a result. Hampton Tedder Technical Services (HTTS) has implemented field observation reports to mitigate these particular reoccurring issues. To promote our safety culture at HTTS, we currently implement safety newsletters, weekly field observation reports, 10-day field safety topics/training, monthly safety calls, and annual retraining safety days. These techniques have allowed HTTS to witness the growth and decrease complacency within our field forces.

2:15 PM–3:00 PM
Implementing & Auditing Your Electrical Safety Program – Is It Compliant?

Speaker: Terry Becker, TW Becker Electrical Safety Consulting

Description:
NFPA 70E Article 110.1 Electrical Safety Program and CSA Z462 Clause 4.1.6 Electrical Safety Program advise of the mandatory requirement for an employer to "implement and document an overall Electrical Safety Program that directs activity appropriate to the risk associated with electrical hazards.  The Electrical Safety Program shall be implemented as part of the employer's overall Occupational Health & Safety Management System (OHSMS), when one exists. Have you documented and implemented an Electrical Safety Program?   What did you base the content (e.g. framework or Table of Contents) of your Electrical Safety Program on?  Did you reference industry Standards for OHSMSs such as ANSI Z10 for the USA or CSA Z1000 for Canada?  Did you research and find any recommendations from OSHA or the OH&S Regulator?  Does your Electrical Safety Program include a qualitative Risk Assessment Procedure? How do you know you have a compliant Electrical Safety Program?   Have you completed an Internal Electrical Safety Audit as a component of the Electrical Safety Program?  How did you develop and implement the Electrical Safety Program? A review will be provided of recommended content for a compliant Electrical Safety Program and a development and implementation process.  A discussion of how you can audit your Electrical Safety Program and update it to ensure it is current will be provided?

3:15 PM–4:00 PM
Human Performance Errors In Power Utility Industry: Approaches and Recommendations

Speaker: Morteza Talebi, TRC Solutions

Description:
Power substation testing and commissioning work critically depends on human performance and coordination as intellectual work has to be distributed among different team members. Human dependability is very high and important in the power utility workforce due to its contribution to power system reliability. The consequences and effect of human error in this industry are instant, costly, and may even result in serious injury or death.

This presentation aims to share the author’s view on current human performance errors in our industry and an analysis of person and systematic approaches. Based on these approaches, a series of recommendations are introduced to help power utilities and companies in reducing or eliminating human error in the power utility industry.

4:15 PM–5:00 PM
Safe Protective Grounding

Speakers: Keith Wallace and Chris Shaw, Safearth

Description:
Significant expense is rightly invested in the design and construction of substation grounding systems for the protection of personnel throughout the life of a substation. Mature consensus standards guide the proper use of temporary protective grounds to work on de-energized substations. These design and maintenance methods rely on a series of assumptions as the basis and building blocks of personnel safety. So, what happens when one of the most basic assumptions is incorrect? What if the temporary protective grounds are not properly attached to the ground grid?

This discussion delves into the technical world of what can happen if the ground grid, structures or equipment are not correctly bonded. Theoretical calculations are confirmed by real life incidents to answer the question: Are your personnel appropriately safe, and are there simple tests available to improve their safety?
