Building an ATV/UTV Training Program for Utilities and Contractors

Utility task vehicles (UTVs) and all-terrain vehicles (ATVs) are quickly becoming the preferred motorized equipment for lineworkers to use to access difficult terrain for necessary inspection and repair of infrastructure. And although they are exceptionally capable, these vehicles – identifiable by their large off-road tires, relatively small size and light weight – pose certain challenges for both utilities and contractors who wish to use them on job sites. This entry is part 1 of 7 in the series APRIL-MAY 2021

Best Practices for Using Your Aerial Device Jib to Handle Transformers

When it comes to lifting transformers, aerial devices equipped with jibs are one of the handiest tools available to lineworkers. Compared to old methods for transformer replacement – which required workers to climb the pole and use a pulley to manually lift the transformer – using a jib is safer, easier and more productive. Most aerial devices sold to companies in the utility industry are equipped with jibs. However, not all jibs are the same, and the user should evaluate the type of work to be done when choosing the equipment for the job. Consider whether the tasks are construction or maintenance...

Aerial Equipment Innovations Aim to Protect Your Workers

Aerial devices have improved exponentially over the last 20 years. Many purchasers and users of the devices, however, are not fully aware of the options now available to them. Technology and innovation – driven by ANSI standards and user collaboration with manufacturers – have resulted in aerial equipment that provides greater functionality and improved safety mechanisms for utilities and operators. In the U.S. and Canadian utility industries, aerial equipment must meet the requirements found in ANSI/SAIA A92.2, “American National Standard for Vehicle-Mounted Elevating and Rotating Aerial Devices.”...

Enhancing Safety for Line Patrol Technicians

Sunflower Electric Power Corp. is a generation and transmission cooperative located in Western Kansas. We have approximately 2,600 miles of overhead transmission lines, which we patrol annually using vehicles. While you may have heard stories about Kansas being flat as a pancake, they are not true. Several areas of our service territory feature deep ravines, water crossings, washouts and rock outcroppings that make line patrols challenging and hazardous. In the past, patrol vehicles used by our line technicians were either pickup trucks or standard-equipped side-by-side all-terrain vehicles...

Are You Driving on Autopilot?

Vehicles have been evolving and manufacturers have been adding safety features to them since the first combustion-engine automobiles were manufactured in the late 1800s. By 1968, all vehicles were required by law to have seat belts, and since 1995, all passengers – adults and minors – have been required to wear them. Anti-lock braking systems became widespread in the 1970s, and the advent of airbags occurred in the 1980s. Today, technology continues to constantly shape and change our world. It is integrated into our daily lives at work and in our homes, from personal electronic devices such...

When Insulating Booms Fail Dielectric Testing

Insulating boom aerial devices and insulating boom digger derricks are designed to provide secondary protection to help prevent workers from being electrocuted. Maintenance and dielectric testing are critical and required by law to verify that the insulating portion of the machine is functioning as designed. A new boom is dielectrically tested at the factory following ANSI requirements for a qualification test to verify the insulating rating. Additional tests are performed to confirm the insulating value after units are finished and operational. Once insulating equipment is placed in service,...

When Utilities Leave the Pavement: Off-Road Driving Safety Challenges

The need to safely access hard-to-reach areas continues to be a struggle in numerous industries, including utilities. Historically, people have pushed the limits of machinery and designed better tools in attempts to access such areas. In the early days of automobiles, for instance, enthusiasts modified and improved the designs of their vehicles, enabling them to travel farther across terrain on which the vehicles were never originally designed to travel. As technology and industry continued to progress, manufacturers began to design vehicles specifically intended for off-road applications,...

Train the Trainer 101: Enforcement of Vehicle Weight and Load Securement Rules

In the past few months, I have received comments and inquiries from all over the U.S. regarding what appears to be stepped-up enforcement of both load securement and vehicle weight rules. It’s not unusual that these topics garner attention from the U.S. Department of Transportation when it comes to carriers, but this recent uptick seems to be for smaller commercial vehicles, mechanics trucks, pressure diggers, and bucket and digger derrick trucks. Not all utility safety professionals may be up to date on this topic because DOT issues are not front-burner issues. Typically, the human resources...

Using Technology to Eliminate Aerial Device Overloads

Knowing bucket capacity and understanding how to read a jib load chart are two critical elements of aerial device operation. While both tasks are fairly straightforward, it is crucial to stay within the allowable capacity of the unit. The platform capacity and material-handling capacity provided by the manufacturer are not recommendations – they are absolute maximum capacities that ensure the machine is not overloaded. Overloading equipment can result in overturning or boom failure. Equipment damage also may occur, resulting in costly repairs and a shortened usable life for the aerial device. A...

Overcoming Barriers to Crane and Rigging Skills Development

The utility industry has high expectations for employing safe work practices and readily invests in equipment and training. Maintaining a workforce with the right skills is a herculean task. Crane operation and rigging skills development presents greater challenges than some other areas because these skill sets typically are not part of the routine work schedule. Individuals with crane operator certification may have fewer than 100 hours of actual operating time in a year, or go more than a year with no seat time or hands-on practice time. OSHA requires employers to ensure that crane operators...

Rope Access Work in Today’s Line Trade

Rope has always been at the core of many operations and is the principal means of removing an injured person from a structure or manhole. In recent years, labor laws have revised and expanded expectations, particularly for worker fall protection on towers. The quest for methods to accommodate these rules has created opportunities for new applications of rope techniques, introducing wider use of rope access and rope descent technologies into the line industry. Rope access describes rope-use techniques that have evolved from centuries-old rope applications incorporating maritime, construction...

Q: We have a group reviewing our personal protective grounding procedures, and they are asking if we should be grinding the galvanized coating off towers when we install the phase grounding connections. What are your thoughts? A: In addition to your question, we also recently received another question about connecting to steel for bonding, so we’ll address both questions in this installment of the Q&A. Your question is about the effectiveness of grounding to towers, and the other question is about the effectiveness of EPZs created on steel towers. We’ll discuss the grounding question first...

Voice of Experience: Inspection, Maintenance and Fall Protection Guidance for Bucket Truck Use

OSHA 29 CFR 1910.67 is the performance-based standard that covers requirements when using vehicle-mounted elevating and rotating work platforms, including the bucket trucks we use in the electric utility industry. There are many types of buckets, and the task to be performed will determine what type of bucket is required. This standard even covers noninsulated work platforms, sometimes referred to as JLGs, used in civil construction. For clarification, a mobile platform covered under 1910.68, “Manlifts,” is not covered under the 1910.67 standard. Mobile platforms are considered mobile scaffolding...

February 2017 Q&A

Q: We are a small, distribution-only municipal utility that has been looking into human performance. We are having some trouble understanding it all and how it could benefit us. Most of the training resources are pretty expensive. Can you help us sort it out? A: We can. Human performance management (HPM) has been around in various forms and focuses since before the 1950s. Throughout the ’50s and ’60s, it seems the focus was on companies performing functional analysis and correcting issues that created losses, thereby promoting more efficient and error-resistant operations. In the ’60s and ’70s,...

Rope Access for Live-Line Work

As a third-generation lineman in the high-voltage utility industry, I can say based on experience that the industry has changed slowly at certain times and radically at others. And yet one thing that has not changed much over the years is the process of performing live-line work on extra-high-voltage (EHV) transmission lines. It still requires the use of live-line tools; it still requires linemen to maintain minimum approach distances; it still requires that linemen possess the knowledge and ability to use tools properly depending on the application, whether it be steel or wood construction;...

Voice of Experience: Switching and Working on UD Systems

I was recently asked to provide information about the challenges and opportunities found when working on direct-buried underground distribution (UD) systems. In light of that request, I’ll address those topics in this installment of “Voice of Experience.” My first opportunity to work on UD systems was as a truck driver operating a trencher in the late 1960s. UD systems were fairly new at the time; lineworkers were learning new techniques, using different types of tools to terminate cables and installing switchable elbows. In that day, some elbows were non-load-break. Back then the work was all...

December 2016 Q&A

Q: We hear lots of opinions on whether a lineworker can lift a hot-line clamp that has a load on it. There is a rule that says disconnects must be rated for the load they are to break. We’ve been doing it forever. Are we breaking an OSHA rule or not? A: Incident Prevention has answered this question before, but it won’t hurt to revisit it and use the opportunity to explain how OSHA analyzes a scenario to see if it’s a violation. Most objections to operating a hot-line clamp (HLC) under load are based on OSHA 29 CFR 1910.269(l)(12)(i), which states that the “employer shall ensure that devices...

October 2016 Q&A

Q: What is meant by the phrase “circulating current” as it pertains to transmission towers? Does it have something to do with the fact that there is no neutral? A: We’re glad you asked the question because it gives us an opportunity to discuss one of the basic principles of the hazard of induction. More and more trainers are teaching with a focus on principles instead of procedures, and we often overlook some of these basic definitions. The concept of circulation is associated with what happens in any interconnected electrical system. Refer to the basic definition for parallel paths: Current...

August 2016 Q&A

Q: We have heard that OSHA can cite an employer for violation of their own safety rules. How does that work? A: OSHA’s charge under the Occupational Safety and Health Act is the protection of employees in the workplace. The agency’s methodology has always assumed the employer knows – or should know – the hazards associated with the work being performed in the employer’s workplace because that work is the specialty of the employer. OSHA’s legal authority to use the employer’s own safety rules as a reason to cite the employer is found in CPL 02-00-159, the Field Operations Manual (FOM), which...

June 2016 Q&A

Q: Is a transmission tower leg considered a lower level? And is there an exception for hitting a lower level when someone is ascending in the bucket truck to the work area? Our concern is that the shock cord and lanyard could be long enough that the person could hit the truck if they fell out of the bucket prior to it being above 15 feet. A: The February 2015 settlement agreement between EEI and OSHA addresses both of your questions, which, by the way, were contentious for several years until this agreement. The settlement agreement includes Exhibit B (see www.osha.gov/dsg/power_generation/SubpartV-Fall-protection.html),...

Train the Trainer 101: Grounding for Stringing in Energized Environments

A few years ago I came upon a crew using 6-inch chocks to hold back a 38-ton crane truck. I told the crew I was happy that they were making an effort at compliance, but I had to ask them, “Why do we place chocks under a truck’s wheels? Is it to comply with our safety rules or to keep the crane from running away?” It was obvious to me that the short chocks would not hold the crane. The driver proved my assumption true a few minutes later. From the cab, with the transmission in neutral, he released the parking brake. The crane easily bounced over the chocks and, unfortunately, hit my pickup truck. Sometimes...

Trenching by the Numbers

By and large, organizations directly provide the training and other resources needed for the development of their foremen and crew chiefs. Such training tends to be built around two components: following the standards set forth by OSHA and other regulatory agencies, and adhering to organizational policies and procedures. This is a great approach but perhaps an incomplete one. Truly impactful safety training typically includes a third component: sharing of personal experience. For instance, I once observed a training session in which the instructor drew from his experiences during a discussion...

Stringing Best Practices: Mesh Grips vs. Preforms

When you ask lineworkers what differentiates their work from general construction, it’s not surprising that they will typically say they work with big lines at high voltages. Lineworkers take pride in keeping lines up and fixing them when they come down. We know that lines do come down inadvertently, and we also know that the losses resulting from such incidents can be substantial. No amount of regulation will combat these problems, so that’s where best practices come into play. Best practices establish the most common methods to achieve operational success within the parameters of regulations,...

December 2015 Q&A

Q: I’ve been reading ASTM 855, IEEE 1048 and the National Electrical Code, and I’m a little confused by the practice of grounding through a switch. Can you help me better understand this? A: In transmission/distribution applications, there is no issue with grounding through a switch. To explain, we always have to ask whether the issue is grounding through (in the path) a switch or grounding (by way of closing) a switch. The application may sound the same, but it depends on which standard you read. Our subject matter experts think the confusion lies in the well-known NEC rules, which require...

Rigging Fundamentals for Utilities

Over the past 20 years I have had the great opportunity to travel the country observing everyday safety practices in the utility industry. During this time it has become clear to me that, more often than not, employees are practicing inadequate rigging techniques that put them and their co-workers at risk on a daily basis. These poor practices are being perpetuated from one generation of riggers to the next. Employees who learned improperly from previous trainers go on to train new employees in the same fashion. It seems that a number of workers have bought into the dangerous idea that unsafe...

Making the Switch

It is an undisputed and well-known fact that workers’ use of manual tools increases repetitive movement, introduces awkward working postures and elevates the risk of ergonomic injuries and illnesses. Throughout the past decade, the utility industry has done a great job of recognizing these ergonomic safety issues, and a number of utility tool manufacturers have responded by developing new battery-operated tools and tool features that address them. Slowly but surely, ergonomic safety is increasing in the workplace as investor-owned utilities, contractors, cooperatives and municipalities make...

Q: I can’t seem to clarify what U.S. Department of Transportation hours-of-service rules apply to utility workers. Are we exempt from the rules? A: The university studies and experience of the Federal Motor Carrier Safety Administration that prompted the hours-of-service rules do have some value to us as an industry with drivers. The data used to form the rules shows that fatigue affects performance. This is a model that can help us to establish safe practices with our drivers. However, there is good reasoning for exemptions when the work we do ensures electrical service for users that...

Mitigating the Risks of Aerial Patrols

A safe and reliable operation is built on a foundation of strong, continually evolving programs that adapt to changing regulations. Federal requirements now mandate that electric transmission utilities perform annual vegetation inspections on all of their rights-of-way. To complete these inspections, many utilities rely on helicopters, which pose high risks due to low-altitude flying and close proximity to lines where the danger of a strike is always present. In the U.S., helicopter wire-strike accidents account for 5 percent of civilian helicopter accidents (see www.ihst.org/portals/54/insights/Wire_Strikes.pdf)....

Q: Can a boom truck be used as a manhole rescue device? I’ve heard that OSHA rules prohibit boom truck use because the truck has too much force, resulting in greater harm to the employee in need of rescue. A: There may be issues with a boom truck as a rescue device, but its use is not prohibited in the situation you mention. Based on the criteria for rescue, however, it’s possible that the use of a boom truck may not be your best option. Incident Prevention does not advocate this method nor any other particular method of rescue from a manhole, but we do make every attempt to give you the information...

Train the Trainer 101: Working from Crane-Mounted Baskets

While the use of man baskets mounted on cranes is common to the utility transmission construction industry, it will surprise many that OSHA has clearly established their premise that cranes are designed to lift loads – not people – and that hoisting personnel with a crane is inherently more dangerous than using equipment designed to lift personnel. For this reason, it is important that safety planners and crews understand OSHA’s intentions for crane-mounted baskets and the issues associated with their use. The crane and derrick standard regulates lifting of personnel, both in a crane-mounted...
