Utility Worksite Safety Articles

Airborne crystalline silica has long been discussed as a health hazard in the workplace. When inhaled, very small crystalline silica particles referred to as “respirable” particles are known to cause silicosis, a fatal lung disease, as well as other respiratory-related diseases such as chronic obstructive pulmonary disease and lung cancer.

Brandon Wylie grew up with line work in his blood from his father and music in his soul from his grandfather, so it was just a matter of time before the two parts collided. And when you cross line work with a passion for music, you end up with a song that can light up a room and help bring recognition to an entire industry. Wylie wrote the song “Highline Cowboy” to express his love of the electric utility industry, and he can be found working on his music when he’s not teaching safety to lineworkers in his role as a certified safety and training specialist for Electric Cities of Georgia.

OSHA 29 CFR 1910.269(l), “Working on or near exposed energized parts,” requires employees to adhere to very specific rules concerning the exposure of unprotected body parts to energized conductors and equipment. I am amazed at the different interpretations of this one paragraph. I have thought about what work practices were being considered by the advisory panel that made the suggestions about how the standard should read when it was being written in the 1980s. The standard is very clear that two qualified employees are required to be on the job site when work is being performed that exposes an employee to minimum approach distances (MAD) on equipment or conductors with nominal system voltage of 600 volts or greater. Why? Is it due to the type of task being performed, or is the second person there for emergency rescue or fist aid? Depending on the task, there may be a legitimate safety reason to require the second employee. Does that second person need to be in the air in a two-person bucket or second bucket to assist, or should they be on the ground observing and available to assist in rescue? The answer depends on whom you ask. I sometimes wonder what the original committee intended.

National equipment standards constantly evolve due to near misses and incidents that occur in the field. This evolution results in electric utilities adopting different work methods and procedures, equipment, education and training to keep utility workers and the public safe as every electric utility company builds and maintains the national electric grid.

I am not an ergonomics expert. I am, however, a former lineman now in my 50s, experiencing aches and pains from many years of working in the field. I became interested in how ergonomics – the field of study that fits the job to the worker rather than the worker to the job – could improve line work after reading an article that explained how We Energies, an electric service provider headquartered in Milwaukee, had conducted a study in conjunction with the Electric Power Research Institute and Marquette University to determine why their employees were suffering so many hand, shoulder, knee and back injuries. It was like a light bulb came on. I thought back to co-workers who struggled with chronic pain resulting from their work as lineworkers and realized it didn’t have to be that way. I started the trade knowing it was a hard job, but I was young and strong. I wanted to impress co-workers and gain their acceptance on the crew, so I worked hard and didn’t concern myself with what I was doing to my body. The veterans who started this same way, and were now suffering the consequences, respected others who were willing to put in the hard work and sacrifice themselves just like they did.

Flashes and contacts continue to happen throughout the electric utility industry. All sectors, from the smallest contractor to the largest investor-owned utility, report incidents every day. I have seen reports that one contractor working a 23-kV circuit locked out the breaker twice in one day. Other reports now indicate that 2013 is trending even higher than last year for the first four months of the year. The industry is on course to meet the average of 24 to 28 fatalities documented in the utility and contractor North American Industry Classification System codes reported to U.S. Bureau of Labor Statistics.

Whenever we are fortunate enough to see a competent climber working off of a pole or tower, it can be favorably compared to watching a well-oiled machine at work. Each part of the body is coordinated and working together. A person with no understanding of the business might think climbing is something anyone can do. It is not. That climber has, more than likely, spent numerous hours learning his craft and practicing it day in and day out during the course of his duties. Even that climber who looks so graceful had to start somewhere, and that is what we are going to look at in this article – how learning to climb at the bottom of a pole or structure can make you a more competent climber at the top.

There are a number of hazards unique to substations. The substation safety information found in this article is drawn from 30 years of personal experience as well as industry best practices, regulations, codes and company policies. During my time working in substations, I have seen some horrible accidents and hope the following lessons I’ve learned will prevent other people from having to experience injury or death.

According to The Humane Society of the United States, there are approximately 78.2 million owned dogs in the country and about 40 percent of all households have at least one dog. Of course, the percentage of households with dogs is higher in suburban and rural areas than in cities, but the fact remains that dogs are nearly everywhere. Couple these statistics with the fact that most households with dogs also have electric service, and those of us who work in the transmission and distribution departments of electric utility companies have a potential problem. OSHA would consider dogs a recognized workplace hazard, right?

Both the NESC ANSI C2 rules and OSHA regulations require signs at appropriate places around utility facilities and workplaces. ANSI Z535 standards that specify the attributes of appropriate safety signs and labels for utility use include ANSI Z535.2: Environmental and Facility Safety Signs, ANSI Z535.3: Criteria for Safety Symbols and ANSI Z535.5: Safety Tags and Barricade Tapes (for Temporary Hazards). The coordinated ANSI Z535 criteria apply to every temporary or permanent safety sign or tag on a utility system.

The threat of high-voltage electrical contact is very real for emergency first responders who are called to the scenes of accidents and other unplanned events. The safety of the public and our emergency workers should be a top priority.

“You fight the fires, we deal with the wires” is a theme that is stressed in the comprehensive outreach program created by NSTAR, a Northeast Utilities company based in Boston. Contacting the utility company first, before any actions are taken by responders, is essential when dealing with an invisible force that travels at 186,000 miles per second. If you make a mistake at the office, you can use an eraser or the delete key to correct it. In the field, there is no forgiveness and a split-second error in judgment will likely lead to an irreversible result.

You’ve said it and heard it many times before: “Accidents happen.” It’s a phrase that essentially allows us to admit that accidents can’t be prevented. In business, that attitude has the potential to breed complacency when it comes to worker safety. A zero injury philosophy, however, maintains that there always exists some combination of tools, work practices and personal protective equipment that enables workers to carry out their assignments without being injured. Consequently, striving for zero injuries makes sense; it is a practical, achievable goal.

The line crew’s job for the day is to replace a 115-kV wooden H-frame transmission structure. No problem – this crew has done this type of work a number of times in the last few years. Upon arrival at the job site, the bucket truck and crane are arranged according to the job plan. A tailgate safety meeting is conducted, during which the clearance is reviewed and the points of isolation are identified. The work procedure is analyzed, including a discussion of the possible hazards and grounding plan for this work site. It is noted that, although not visible from this work site, this transmission line does share a right-of-way with two other high-voltage transmission lines about 15 miles from the work site. Induction could be an issue on this job. Maintaining a proper equipotential zone is emphasized.

Following is a treatment of the complex subject of enclosed space rescue and it's a lot of information. I would like to just tell you what to do, but there is no single solution. Your background understanding of the relative standards, interpretations and directives is necessary for you as trainers and administrators to mount an effective enclosed space program.

Ferroresonance is a complicated issue. It is important to familiarize crews with ferroresonance because as the number of URD systems installed increases and as systems age, the incidence of ferroresonance increases and so does the threat to equipment, service reliability and, most importantly, the safety of workers and customers.

The electric utility industry is loaded with potential hazards. Climbing at heights is one of those inherent safety risks that come with the job. At Louisville Gas and Electric (LG&E) and Kentucky Utilities (KU), we require 100 percent fall protection on poles and towers for our employees and business partners. This policy is part of our “no compromise” approach to safety and supports our belief that we can leave nothing to chance when it comes to the well-being of our workers.

What do safety rules mean to the organization? To the worker? Does having a safety rule mean it has to be followed 100 percent of the time, part of the time or not at all? Most employers and employees would say 100 percent of the time. So why do safety rules and actual work practices not match up every single time? Is the rule not known or not understood, does it not fit the application or has it always been done that way?

No matter what time of year you are operating your utility truck, there are always best practices to follow for safe setup, operation and transportation. Particularly in colder weather when temperatures drop below freezing and stay there for an extended period of time, there are some specific things you need to keep in mind in order to keep your truck running and your crews productive.

Alliant Energy (AE) management and International Brotherhood of Electrical Workers (IBEW) union personnel began looking at the 100 percent fall protection issue about four years ago. AE is comprised of two utilities: Wisconsin Power and Light (WPL) and Iowa Power and Light (IPL). Union workers are represented by five IBEW locals. Internal statistics regarding falls during climbs on wood poles showed numbers in the teens over the last few years and a trend of near misses and minor injuries.

All-terrain vehicles, also known as ATVs, have a long-standing reputation for being unsafe and dangerous for riders and passengers. Operational injury statistics are staggering, averaging well over a half-million injuries in the U.S. since 2004. Although many injuries are linked to recreational use, ATVs in the workplace are expanding in a variety of industries, thus increasing the risk of job-related injury.
