Circuit breakers are important for preserving the electrical system during abnormal conditions as well as protecting workers' lives. Note the number of rollers and bearing surfaces in the operating mechanism. These require lubrication and, as the circuit breaker is in service, that lubricant dries out and becomes gummy. This slows the circuit breaker down, changing its operating speed. It's important to note this change in operation speed will alter the results of a previously performed arc flash study. Source

When I was in boot camp, our drill instructor told us that assume makes an ass out of u and me. It was true then, and it is true today. In this instance, assumptions came into play several times, both by the worker and by the companies involved. The good news is that it did not result in a fatality, but that does not relieve the pain and suffering that the employee had to endure. This same type of scenario is likely repeated at many job sites throughout the United States. Multiple contractors, dozens-maybe hundreds-of workers, power system equipment and devices; all of these have to be taken into consideration when performing maintenance activities. It can become a blur. Copyright © 1996-2013 1105 Media Inc. Source

Temporary protective grounding serves a critical safety function when working on electrical power systems. Although many field service personnel are well familiar with the requirements of using temporary protective grounds, many others have only a partial understanding of important aspects of it. This paper reviews the more important aspects of the application of temporary protective grounds, including sizing, order of placement and removal, results of misapplication, and common rules for working with temporary protective grounds. © 1972-2012 IEEE.

This paper reviews some of the more common electrical safety myths and misconceptions field electrical workers often have. Many of these misconceptions continue in spite of training and education. Some are handed down from worker to worker, similar to tribal knowledge. The real danger from these misconceptions is that they impede the truth and cause electrical workers to misjudge hazards and risks. © 2013 IEEE. Source

This case study will be a chronicle of events that were encountered through on site interactions with electrical workers, corporate managers and safety professionals at a large national hospital facility during an arc flash/blast incident in a utility vault that severely burned an experienced electrical worker, an experienced utility worker and a hospital maintenance director. The goal of this presentation is to communicate the specific accounts and challenges that allowed the incident to occur and the human failures from the site executives and safety professionals throughout the recovery process of the site. Many of the cultures that were exhibited during this project seem to plague many utilities, hospitals as well as general industry today, even with the heightened awareness on electrical safety and qualifications of workers. There were several key strategies employed by the site recovery personnel to counter the site hazards. The hazards included exposed conductors, poor equipment grounding, inclement weather, human factors, limited qualified recovery personnel, as well as the site management's limited knowledge about electrical safety, their electrical system and disaster preparedness. Key lessons were learned that should be communicated to safety professionals everywhere: 1. What are the challenges involved when working on a recovery project after an electrical disaster that affects two employers and pending legal action is likely? 2. How can the 'Energized Work Plan' be used to get the attention of executives and safety professionals. 3. How is it possible, even after a traumatic near life loss incident at the hospital utility vault that the safety and maintenance culture of both employers involved in the incident have not changed? © 2013 IEEE.
