It’s a busy time in our industry. We have challenges associated with normal operations and maintenance of the grid. We’re also faced with new and increasing work involving distributed generation, vehicle charging infrastructure and major transmission projects.
Both existing and emerging work require access to the respective work areas, and with this comes the associated hazards of off-road access work. As an industry, we talk about the electrical hazards of our work all the time, and we should. But we don’t spend a lot of time talking about access work hazards before and after the electrical work is done. This article is intended to get you thinking more about right-of-way access and matting.
Before any work begins, a strong work plan sh…
Flame-resistant (FR) and arc-rated (AR) apparel are garments specifically designed to protect the wearer from the hazards of flame and heat, including arc flash and flash fire. This type of personal protective equipment (PPE) is most commonly worn by workers in high-risk industries such as electric utilities, welding, and oil and gas.
Donning of FR/AR apparel is one of the most essential practices in place for protecting workers from the flame and heat hazards they may encounter on the job. However, this type of clothing also has a significant impact on the environment. As legislation and consumer demand for more sustainable options continue to increase, it’s important to understand that sustainability goes beyond simply recycling appare…
Your PPE can protect you if it’s in good working order and used properly, and this is especially true of fall protection gear. All gear should be inspected before use because a deficiency can be dangerous. Damaged or defective equipment should be immediately removed from service, as should equipment that’s been used in a fall. Anything that compromises the ability of the gear to protect someone from a future fall is a potential risk.
Harnesses and safety lanyards cannot be repaired; any damage to them means the entire unit is too dangerous to use. During inspections, the components of a fall protection harness must be in perfect working order before the harness is donned and used for working at heights. It’s helpful to think of this type…
Influence sways our beliefs and our direction in life. We are swayed by the news, public opinion, social media, our family and friends, and by some things we don’t even know are influencing us.
In the utility industry, this begs the question: How do we as leaders go about influencing those around us in ways that will help to make us safer? What types of influence might resonate with the workforce?
Influential Actions
Our approach to influencing any crew or situation matters. Let’s say there is a pressing tactical matter on a job or a change in scope that needs to be discussed. Since that issue is foremost in the leader’s mind, they may come right out with the information before making sure the crew is ready to be engaged. We all have dif…
Like nearly all industries that require skilled workers, the electrical utility industry currently faces the challenge of having enough trained and qualified workers to meet demand and changing market conditions.
According to a 2020 U.S. Energy and Employment Report (see www.usenergyjobs.org), all energy sectors reported hiring difficulties: “Lack of experience, training, or technical skills were again cited as the top reasons for hiring difficulty by employers across all five surveyed sectors. The need for technical training and certifications was also frequently cited, implying the need for expanded investments in workforce training and closer coordination between employers and the workforce training system.”
One solution is to improve…
The question about what’s permitted for operating aerial devices and digger derricks in high winds is one that comes up frequently with users. Utility crews often must deal with working in wind. Trouble trucks responding during storm recovery, transmission operations to place visibility balls on lines and working above rooflines in urban locations are just a few examples. Plus, some areas of the country experience high winds regularly or seasonally.
While OSHA restricts use of material-handling aerial devices and digger derricks in winds greater than 30 mph, the reality is that both OSHA – in its General Duty Clause – and manufacturers require that operations cease in wind speeds that may be less than 30 mph if the work conditions are no…
Imagine you are working in a remote wilderness area on difficult terrain. The job involves setting poles, running wires, trimming trees, operating heavy machinery and working at elevation in track bucket trucks or hooks on a pole. The potential for serious injury is present, and extrication will be difficult if an injury occurs.
This scenario begs the question, are basic first-aid and CPR training enough for a situation like this? Should enhanced first-aid training be considered for remote utility work? Could training some of our lineworkers in advanced first aid help them more effectively respond? Would training them help them to recognize potentially hazardous situations in advance to avoid injuries altogether?
As a utility worker wi…
Q: Why does grounding alone not prevent static discharges, and why don’t we have to ground all flammable dispensing drums and stations?
A: “Flammable” is a relative term, and some of the written standards are detailed to the point that they can be confusing. The best thing any facility can do is to consult a chemist, chemical engineer or fire science specialist to survey and equip your flammable operations.
The simple explanation has to do with volatility, which is how easily a chemical vaporizes and then how flammable that vapor becomes and at what temperature. Every chemical in the workplace should have a safety data sheet that lists the material’s vapor point and relative flammability. The issue then is the material’s vapor flash poin…
Bucket trucks are among the most frequently used pieces of equipment in a utility’s fleet. Because of the common use of the trucks, it becomes easy for operators to become complacent in their equipment, inspection, operation and rescue plan – often defaulting to the last job safety analysis with limited consideration for the task at hand and the work environment.
In a frequent scenario, one of Colorado’s electric utility contractors was issued an urgent service ticket. The lineman assigned to the job had years of experience and assumed this task would be much like the hundreds of closed service tickets in his past. Due to time constraints, time of day and ease of repair, he set off solo to complete his mission. Upon arriving at the scene…
On October 27, 2021, OSHA published in the Federal Register an advance notice of proposed rulemaking for heat injury and illness prevention in outdoor and indoor work settings. This followed OSHA implementing an enforcement initiative on heat-related hazards and the development of a National Emphasis Program on heat inspections in September. At the same time, the agency formed a Heat Injury and Illness Prevention Work Group of the National Advisory Committee on Occupational Safety and Health to start collecting information in preparation for the rulemaking.
Past
Not many hazards found in the workplace share the same historical prevalence as heat stress. In fact, one could surmise that workers getting sick or injured while working in the…
The topic of step and touch potentials is controversial, which is precisely why we need to discuss it. In my role as a work methods auditor and consultant, I see more variations in how employers address step potential than in any other aspect of equipotential bonding. I know the reasons for this and will address them here. But first, I need to clearly state the following:
The theoretical argument for hazardous step potential in electric utility work environments clearly exists.
Every employer must assess the hazards of step potential in their work environments and adopt a plan to protect exposed workers.
Every employer must train their employees to recognize step potential hazards and employ the procedures necessary to protect workers f…
Q: Why are communications systems bonded to a utility system neutral? Doesn’t that make the communications messenger a parallel neutral path?
A: Yes, it does, but this is a case of “Which is worse?” There are a number of things we do for one purpose that create hazards for another. We must know the issues and choose what we will do. Down guys are one example. In transmission and distribution, many utilities install insulators in the upper section of a down guy to isolate it from the electrical environment at the top of the pole. The purpose is to protect the public from the potential of a hot guy. Then the engineer calls for a bond connection below the insulator to ground the guy, further ensuring the guy cannot become energized, again t…
Protection from Flames and Electric Arcs
It is important to remember that all arc hazards are not equal.
By Pam Tompkins, CUSP, CSP, and Matt Edmonds, CUSP, CIT, CHST
According to OSHA, electric power generation, transmission and distribution workers face a significant risk of injury from burns due to electric arcs. Studies have concluded that a large percentage of arc-related incidents resulted in either a fatality or in extremely painful third-degree burns, which require skin grafts and leave permanent scarring. Based on these conclusions, OSHA adopted standards to address forms of personal protective equipment other than clothing. These standards – titled “Protection from flames and electric arcs” and found at 29 CFR 1910.269(l)(8) an…
Q: Is it a good idea to wear dielectric boots in a substation? Do they provide additional protection to a worker? We feel that the worker is at equipotential – given the grid and stone are maintained per design – so we don’t believe that dielectric boots would provide extra protection. What are your thoughts?
A: The design of the substation’s grid has two purposes in its construction. One incorporates ground rods to create a low-resistance electrical path to get harmful voltage and current into the earth to protect the equipment in the station. The grid itself helps by interconnecting the rods. To most of us, the second purpose is more important. The grid creates a plane of bonded equipotential across the ground in the substation. The cr…
Consider new testing data before making a final determination.
Proper grounding is both a life-and-death matter and an operational imperative. But many questions remain about grounding. Some of the most frequently asked include:
Why do some designers, utilities and contractors use one type of grounding conductor while others use a different type?
If copper and aluminum carry power through transmission and distribution lines, then why not use them everywhere, including for grounding?
What is the best grounding conductor?
The grounding conductor selection process should include both of the following steps:
Use the recommendation from Section 9 of the National Electrical Safety Code, which states that choosing a conductor to satisfy a g…
You might be surprised how a little thing like a safety sign can turn out to be one of your company’s biggest financial losses of the year. Over the last decade, I’m aware of three clients who lost big because a sign they put up was the wrong color, the print was imprecise, or the employer didn’t have a sign policy or effective safety sign training.
Let’s start with having a sign policy. When helping to develop any policy, I always tell clients that the policy you write is only as good as the training you provide when you roll it out. For instance, if I were to research signs in preparation for a sign policy, I would likely start with the ANSI Z535 safety sign standard. That is where you find the results of the research and testing perfo…
Pandemic preparation is nothing new. In fact, I have been telling employers since the 1980s that a pandemic plan is one of the business/safety mechanisms they should have in place. It’s just good practice to address and interrupt a contagion that could potentially immobilize the employer’s workforce.
The United States has been researching pandemic responses since a swine flu outbreak in 1976, but few if any publications back then addressed workforce contagions. The earliest literature on organized pandemic responses appeared around 1976 when the U.S. government established formal research panels to develop a nationwide response to a pandemic threat. The panels performed research and modeling activities and revised and expanded both resea…
Demonstrating simple strategies for teams to practice can begin to effect behavioral changes that improve safety.
When leaders model a specific safety behavior or tactic, we can achieve multiple positive outcomes, including initiating change in our organizations. It is critical, however, that we physically model the behavior with our actions – we must walk the walk, not just talk the talk. When we truly lead by example, we can expect our team leaders to model our behavior as well.
With that said, in this article, I’m going to present you with some simple, actionable safety strategies you can model that will begin to change your company’s culture of safety and crew dynamics.
The Confidence to Speak Up
During incident and accident investi…
Incident Prevention magazine still receives many questions about the different facets of equipotential bonding. In this installment of Q&A, we provide detailed answers to several of the most frequent questions in an effort to help the industry better understand and resolve these issues for the safety of their workers who use temporarily grounded systems.
Q: We have heard that we should be bonding baskets to the grounded transmission or distribution bus to equalize voltage differences between the basket and grounded phase. The idea of using a jumper bond from an insulating aerial lift to the grounded overhead conductor is new to everyone. How does this work, why do we need to do it, and how should we do it?
