Overcoming Barriers to Crane and Rigging Skills Development

Web-Dickinson-4

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 are trained and competent without exclusion for any industry. Even while safe crane operation and rigging are critical to utilities, the lack of seat time and skills maintenance is a growing concern among utility safety departments. A strategic approach to developing those skills across business units is essential to maintaining the industry’s above-average safety record.

However, utilities, like most large, complex organizations, battle the 5 C’s: complex corporate culture causing complications. Different groups within the utility may, out of necessity or for other reasons, operate as silos, with little shared knowledge or resources. Construction groups, T&D and emergency response crews have different needs when it comes to crane operation skill levels. The differences between operating boom trucks or digger derricks and large telescopic or lattice boom cranes must be recognized when training individuals for typical or emergency response work environments. Yet the reality of maintaining skill levels may require staff and budget that conflict on the surface with corporate cultures that thrive on efficiencies.

To maintain qualifications in the various areas of responsibilities, utilities need to plan for and schedule practice time with cranes and rigging to reinforce and verify skill ability. Relying on a weeklong refresher training course once every five years is not sufficient for retaining competent crane operation skills.

Rope Access Work in Today’s Line Trade

Web-Rescue_v1.00_00_33_20.Still009

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 and, in particular, mountain climbing or controlled descent methods. In the firefighting world, rescue using rope is referred to as “high-angle” or “technical” rescue. Rope access has been used for centuries in construction, and most readers today are familiar with scenes of lumberjacks, wind energy blade inspections, and dam and bridge inspectors suspended over the sides of structures.

In the line trade, we traditionally think of rope in terms of its use as a handline, which, in the event of an emergency, doubles as a rescue line. This rescue technique is still as relevant now as it was in the late 19th century, as the idea to plan your rescues is not a new one. Any differences between rope rescue today and rope rescue in the early days of power lines are primarily due to technological advances. One example of these advances is Buckingham Manufacturing Co.’s OX BLOCK, which is used for hurt-man rescue and self-rescue, as well as lowering, raising and snubbing loads.

To the employer researching rope access and controlled descent techniques for workers, it is important that line personnel be involved in the research process so that the techniques, tools and training that are adopted effectively match the needs of the workplace. Keep in mind that rope access is not a substitute for all work tasks – it is simply another tool. Both training and research are critical for employers and employees considering rope access techniques; this includes the review and assessment of tools and other items currently available on the market, including rescue-rated blocks and property-rated handlines.

June 2017 Q&A

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 and then move on to the EPZ question.

As to grounding effectiveness, we have two thoughts here – one simple and one that likely will raise more questions than we can resolve in these pages.

The simple thought is this: Consider grounding to the circuit static. It’s difficult to reach but doing so makes it easier to create an electrical connection. Using the system static shares current with adjacent structures and reduces current on the structure being worked. Dividing current among adjacent structures also reduces ground potential’s risks to workers at the foot of the tower. See the following Q&A regarding EPZ if you are grounding to the static.

As to connecting to the tower, grinding off the galvanized coating opens the underlying steel to corrosion and would need to be replaced after the operation. We have asked how utilities make connections and found that most use a flat clamp to a brushed plate or insulator bracket, or a C-clamp to a brushed bolt or step. Either method is a good one. Others follow one of the recommendations in IEEE 1048, “IEEE Guide for Protective Grounding of Power Lines,” 9.2.1.1 for lattice using a ground cluster. The cluster serves two purposes: providing a clamping connection and keeping the clamps close together.

Fortunately, the structure connection can be installed by hand, making the cleaning and mechanical security of the connection pretty reliable. There are several considerations to discuss that should be part of the training provided to lineworkers who make these connections.

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 and require standard guardrail protection. Additional fall restraint normally is employed depending on the type of work and availability of fall protection attachment points.

Although today our industry is better trained than ever, it wasn’t so long ago that one of the most violated standards was the requirement to fly the booms every day before employee use. According to paragraph 1910.67(c)(2)(i), “Lift controls shall be tested each day prior to use to determine that such controls are in safe working condition.”

The fall protection requirements for utility bucket trucks are currently covered under 1910.269(g), “Personal protective equipment.” The users of bucket trucks now have options for fall protection, including a personal fall arrest system, fall prevention or a retractable lanyard. Fall protection equipment is much more user-friendly and lightweight than ever before.

In the remainder of this article, I want to focus on bucket truck inspections and maintenance required by OSHA, manufacturers and others. This information is critical but sometimes is not followed by employers or employees, which has led to a number of catastrophes.

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, much of the literature on HPM seemed to surround the nuclear power industry, and indeed the introduction of HPM into the transmission/distribution side of the utility industry appears to have come through the generation side. In the ’70s, researchers began to experiment and write about more closely analyzing the knowledge and skills of the performer. It took a while to sink in, but the safety industry began to research HPM as a culture analysis and risk prevention tool. It makes sense. Human performance – in particular knowledge, skills modes, decision-making modes and performance – affects all of every enterprise whether you have an HPM program or not. Organizations are made of people. HPM has identified and categorized commonalities in types of personalities that predict how people make decisions and perform tasks. Studying human performance also can help identify safety culture issues and risk behaviors. It’s not a big or expensive step to train your workforce on problem-solving and decision-making characteristics of the human mind. Soon they will understand their own processes and the limitations of the way they naturally think, allowing them to make adjustments toward better performance. So if we can take advantage of HPM to prevent incidents, why not do it? Most organizations start small. Pick a few key people to begin training on the basics of HPM, and then look at your organization to see where the initial undertakings can do the most good. There are several experts associated with Incident Prevention who will be glad to help should you need it. Additionally, on the iP website (www.incident-prevention.com) you can find numerous HPM articles in the iP archives as well as information and training sessions from past iP Utility Safety Conferences. HPM works. We hope you will pursue it.

Creating a Safe Driving Culture

Creating a Safe Driving Culture

At ComEd, as with any other electric utility, keeping the lights on is important. However, no job is so important that it cannot be done safely, and that includes driving to and from the job site. Over the past few years, ComEd – a unit of Chicago-based Exelon Corp. and the largest electric utility in Illinois – has worked diligently to educate its drivers about safe driving practices, help them develop skills and learn techniques to avoid accidents, and raise awareness about the many distractions that can occur on the road today. Drivers are encouraged to “treat driving with the respect it deserves,” whether at a reporting location, on the road or at a customer’s property.

ComEd’s Safe Driving Initiatives
Defensive driving, according to the National Safety Council, is defined as “driving to save lives, time and money in spite of the conditions around [the driver] and the actions of others.” In order to set clear expectations for its driving force, ComEd has adopted a driver safety program to help its drivers improve their defensive driving skills. Following are descriptions of a number of safe driving initiatives included in the driver safety program that have worked for the utility.

Smith Driving System
This is the foundation of ComEd’s safe driving program. All employees who drive company vehicles are trained on the Smith Driving System, which is based on five key principles:
1. Aim high in steering. Make sure you’re looking far enough ahead of your vehicle so you have time to react to any hazardous situation that may present itself.
2. Get the big picture. Keep the acronym G.O.A.L. – Get Out And Look – in mind, and search for hazards all around your vehicle.
3. Keep your eyes moving. Don’t stare in any one direction while driving; use your peripheral vision and continuously scan the entire area.
4. Leave yourself an out. Always have an identified escape plan for you and your vehicle.
5. Make sure they see you. Help other drivers be aware of your presence by using the tools at your disposal, including the vehicle’s turn signals, brake lights, headlights and horn.

Rope Access for Live-Line Work

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; and it still requires access to the energized end of the insulator string or conductor. For many years the method of accessing the “hot end,” as we call it, required the use of live-line-rated aerial lifts, horizontal or vertical live-line insulated ladders or, in some instances, helicopters. Each access method has its own set of intricacies that can be time consuming, labor intensive and costly, but all of the methods have the same end result when the procedure involves the bare-hand method for conducting the maintenance work. Live-line maintenance using the hot-stick method is another topic entirely, so for the purposes of this article, I am only going to address live-line bare-hand work.

Creating a New Tool
Well before OSHA’s final rule regarding 29 CFR 1910.269 and 1926 Subpart V was published in 2014, ushering in new fall protection standards, the live-line bare-hand committee within the company I work for – Tri-State Generation and Transmission, headquartered in Westminster, Colo. – began to think a great deal about providing our linemen with a new tool for performing traditional live-line work. Ongoing environmental and related job site concerns also impacted our thought process at the time. Those concerns included a lack of rights-of-way; earth disturbances caused by the need to access structures and set up aerial lift equipment; the possible need to re-vegetate earth that we disturbed during a job; lack of ability to de-energize transmission lines requiring live-line work; and the costs associated with the use of helicopters for routine live-line EHV maintenance.

The time the committee spent thinking about creating this new tool for live-line work was the beginning of developing Tri-State’s rope access and rescue program for live-line bare-hand work. Basic work methods did exist at the time, but we wanted a rope access program that provided greater training and direction and could include rescue at a level that hadn’t existed before but that we as linemen had always wanted. As time went on, we began to develop a comprehensive process for performing live-line transmission maintenance just as we had always done with ladders, trucks and helicopters, and it was – and continues to be – every bit as efficient, cost effective, rescue enabled and, most importantly, safe.

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 about proper use of tools, identifying equipment and following the minimum rules. There were no OSHA regulations. We learned many techniques and work practices the old-fashioned way: through the school of hard knocks.

The challenges that workers faced back then are much the same as they are today, with two exceptions: The industry has more experience installing and operating UD systems, and equipment is now much more technically sophisticated and reliable. For many years, maintenance of UD systems was nonexistent. The common approach was to dig a ditch and put cable in the ground, and industry workers believed everything would last forever. That belief was short-lived; within a few years, external concentric neutrals began oxidizing, and radial and loop-fed systems suddenly became single-conductor, earthen-ground return systems. Driven ground rods at transformers split coil for secondary voltages. There was no neutral conductor for return currents or fault current flow.

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 used by employees to open circuits under load conditions are designed to interrupt the current involved.” There are some utilities that prohibit operating HLCs energized, and there’s nothing wrong with that. Our purpose at iP is not to judge an employer’s operational rules but to enlighten and educate the industry.

On its face, the rule seems to prohibit use of an HLC to break load. Anybody could also argue, then, that any operation of an HLC must be dead-break since HLC manufacturers offer no load-break value at all. However, there are several facets to analyze in this scenario. First, if a non-rated HLC cannot be lifted under load, how about a drop-out switch? We operate those thousands of times a day without injury to the employee, although sometimes an ill-advised operation does smoke a pole top. There is nothing in the rules that prohibits an employer from making an engineering-based decision establishing criteria or protocols for operating HLCs or drop-outs under certain load conditions. Primarily, the employer’s determination would be based on risk to the employee and risk to the equipment. For OSHA, the primary consideration would be risk to the employee. Just as in the working alone rule, if the device is operated by a hot stick from a position that prevented injury to the employee, there would be no violation. Second, what would be the solution in the scenario? If the solution required installing a mechanical jumper and installing a load-break switch, would such an operation add risk exposure to the crew, and would adding the switch really enhance the safety of the operation? At the very worst case, the scenario – operating the HLC under load – could be ruled a de minimis violation. De minimis is the level of violation where OSHA recognizes that a direct rule was violated, but there was no other way, or no safer way, of executing the required task, and there was no risk to the employee.

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 flows in every available path inversely proportional to the resistance of the path. That means that current flows through every path, and the path with the least resistance has the most current flowing in it. Inversely, the path with the most resistance has the least current flowing in it.

When you ground a circuit to the structure, you are making an electrical connection to the tower. Current will flow in every available path. If there is any source for current, including induction, there will be current flow. The greater part of the current will flow in the lower-resistance pathways. If the tower is well grounded, the majority of the current will flow in the tower to ground. In a distribution system, the majority of the neutral current flows in the neutral. Pole bonds to ground rods have much higher resistance and therefore lower current that usually can’t be measured by a typical clamp current meter, so some people think there is no current flowing in them. There is, and under the right conditions – such as a fault or open in the neutral – the level of current flowing in a pole bond can be deadly.

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 is published by the agency for compliance officers (see www.osha.gov/OshDoc/Directive_pdf/CPL_02-00-159.pdf). The explanation is in the FOM section about the elements required for a citation under the General Duty Clause, in particular Chapter 4, Part III, Section B, Entry 6(a). This part covers the required element of employer recognition. If there was no reasonable expectation that the employer could recognize the hazard to the employee, the employer cannot be cited for a violation. The FOM specifically states that employer awareness of a hazard “may also be demonstrated by a review of company memorandums, safety work rules that specifically identify a hazard, operations manuals, standard operating procedures, and collective bargaining agreements. In addition, prior accidents/incidents, near misses known to the employer, injury and illness reports, or workers' compensation data, may also show employer knowledge of a hazard.”

Train the Trainer 101: Practical Recommendations for Wire Stringing

In the last installment of “Train the Trainer 101,” we discussed grounding when stringing in energized environments (see http://incident-prevention.com/ip-articles/train-the-trainer-101-grounding-for-stringing-in-energized-environments). Many readers responded with questions regarding the myriad issues they have faced during stringing. I learned a lot about this type of work during my first 25 years in the trade. In stringing hundreds of miles of conductor, I am proud to say I never dropped wire. I also have to say it’s most likely I have that record because I learned a great deal from other workers’ accidents. In fact, I am seriously afraid of dropping wire. Stringing incidents are some of the most dangerous in the trade, not only risking the lives and limbs of line personnel, but creating a serious risk to the public. Over the years I have heard of or investigated every kind of incident, including one in which a phase dropped during clipping, shearing off 26 side-post insulators before the carnage ended. Wire ended up across school driveways, shopping center parking lots and intersections. More than 40 cars suffered damage and dozens of people reported injuries. I’ve seen wire dropped across interstates and rivers, and it always happens at the worst time. You’d be surprised how much damage 1272 can do to a luxury boat. So, the remainder of this installment of “Train the Trainer 101” will focus on some recognized issues and tips that might help prevent future disasters when stringing goes bad.

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), which explains how the new fall protection rules will be enforced or cited by OSHA. Employers should review the entire document.

Section A of Exhibit B states that no citation will be issued because a fall arrest system could permit the employee to contact a lower level while the bucket is ascending from the cradle or to the cradle position, provided that the fall protection is compliant in all other respects, the bucket is parked with brakes set and outriggers extended, and there are no other ejection hazards present.

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 I ask similar questions about grounds installed during stringing. That’s because it seems we do not pay as much attention to the value of grounding as we do to the perceived value of an act of compliance. Grounding during stringing plays a very important role in protecting workers; however, that’s only the case if we know why we are grounding and then install grounding so it does what we want it to do.

Trenching by the Numbers

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 about how to troubleshoot problems that can likely be anticipated in the field. Often, this type of training is held in higher regard by trainees than that which simply outlines a standard. Furthermore, workers are more likely to become active participants in training sessions that highlight proven, real-world work practices that they can use to more safely and efficiently execute their tasks.

With this in mind, I began crafting a series of four articles that focus on trenching and excavation techniques and practices. My goal is to present advanced material – injected with my own on-the-job experiences as a safety director and instructor – to the seasoned foremen and crew chiefs who already have some practice working in and around trenching environments.

Stringing Best Practices: Mesh Grips vs. Preforms

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, provide work techniques inclusive of the collective trade experience and debunk field-level work practices that counter those efforts.

Each year thousands of miles are strung, and many lineworkers have likely wondered how many lines have dropped due to misaligned or misapplied practices. In fact, we asked this same question at Allteck, which prompted research into the matter; our goal was to compile the best working knowledge about some stringing problems commonly encountered by workers in the field. The prevention strategies regarding this topic appeared limited, and most stringing information related to post-incident countermeasures, such as the bonded and grounded stringing site.

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 permanent installations to have a connection-free path for the ground electrode conductor at the service entrance of an electrical system. According to the code, grounds – except in some specialty connections – cannot be disconnected through operation of a switch or breaker contact. ASTM 855 is an equipment manufacturer's standard that has no application to utility practices in the field other than being used as a guide for shop construction, sizing, rating and assembly of personal protective grounds. IEEE 1048 does address the value of having the grounding switches closed when de-energizing a system for work; that ground switch is a very low-resistance path to earth at the feeder or transmission bus source that will lower fault current in an accidental or inadvertent energizing of the source. The ground switch in the station is also a path to ground that will divide and help reduce the amount of induction current on a circuit. Closing the switch can help reduce induction current at a work location, depending on how far apart the work location and the ground switch are.

Rigging Fundamentals for Utilities

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 practices are acceptable as long as they don’t result in a serious accident. This cycle of carelessness and endangerment is unacceptable and can only be stopped through adequate training and reinforcement of proper rigging techniques. We must revisit the most fundamental principles of rigging safety to build the foundation necessary to change our current culture. In this article I will discuss three of the most basic aspects of rigging – equipment selection, inspection and proper use – and I look forward to continuing the conversation when I present “Basic Rigging Fundamentals” on September 30 at the iP Utility Safety Conference at ICUEE.

Making the Switch

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 the switch from manual to battery-operated tools.

However, even with the progress that’s been made, there are many workers who are still using manual cutting and crimping methods on job sites across the country, which means those individuals face a greater likelihood of carpal tunnel syndrome, tendonitis, sciatica, sprains, strains, soft tissue damage and other injuries.

According to the most recent data available from the U.S. Bureau of Labor Statistics, among upper body injuries involving the repetitive use of tools, approximately 61 percent involve injury to the hands and wrists, 20 percent involve injury to the shoulders, 10 percent involve injury to the arms and 9 percent involve injury to the trunk and back. Signs of these of musculoskeletal disorders include decreased range of motion, decreased grip strength, swelling, cramping and loss of function. Other symptoms of these injuries include numbness, pain, tingling and stiffness.

Arrive Alive

Arrive Alive

On a clear, sunny day following a fierce thunderstorm the night before, Mark drove off to work. The schedule for the day was busy with repairing downed lines in several heavily trafficked neighborhoods followed by some scheduled maintenance at a router station. Mark met up with his crew, reviewed the schedule and then the team headed out for what they expected to be a long day. The crew was experienced, though, so Mark felt confident they would be able to complete their list of tasks.

In the driver’s seat of the crew cab on the way to repairing the downed lines, Mark thought about the task ahead; it would pose a challenge, but he and his team knew the drill and felt comfortable navigating to the assigned areas.
