Ergonomics in Utility Field Work: Reducing Musculoskeletal Risk in Meter Installation and Maintenance
Introduction
Utility field work presents a unique ergonomic challenge. Unlike a manufacturing facility or traditional workplace, the work environment cannot always be designed around the employee. Technicians must adapt to wherever equipment happens to be located—along buildings, below grade, on slopes, in landscaping, and in other confined or difficult-to-access locations.
A recent ergonomic evaluation of utility meter technicians illustrates how these environmental constraints can combine with forceful exertions, repetitive tool use, material handling, and prolonged low working postures to create significant musculoskeletal risk.
The evaluation included field observations of residential and commercial meter installation and repair activities. Technicians routinely traveled between jobs and worked with gas, water, and electric meters using a combination of hand tools, powered tools, vehicles, and specialized equipment. Work was performed outdoors in varying weather and terrain conditions, with technicians typically completing approximately 8–15 work orders per day.
The findings demonstrate an important principle for utility organizations: when the work environment cannot be controlled, reducing ergonomic risk requires improving how employees, tools, equipment, vehicles, and work practices interact with that environment.
The Ergonomic Challenges of Utility Field Work
Field-based utility work differs substantially from work performed at a fixed workstation.
A technician may begin one job standing comfortably at waist height and perform the next while kneeling on rocks, working on a slope, reaching around landscaping, or manipulating a heavy tool only one or two feet above the ground.
The evaluation identified several recurring ergonomic exposures:
Awkward and sustained postures. Meter work frequently required bending, squatting, kneeling, lunging, twisting, reaching, and neck flexion. Because meters are commonly positioned close to ground level, technicians often had limited ability to select an ideal working height or posture.
Forceful exertion. Technicians applied force when lifting and positioning components, tightening or loosening fittings, using pipe wrenches, carrying tools and materials, and manipulating meter assemblies.
Repetitive upper-extremity activity. Wrenching and tightening fittings created repeated motions through the hands, wrists, elbows, and shoulders.
Contact stress. Kneeling on rocks, mulch, soil, and other uneven surfaces increased stress on the knees and surrounding tissues.
Vibration. Powered tools such as impact wrenches introduced vibration in addition to the postural demands associated with positioning and controlling the tool.
Material transportation. Tools and components frequently had to be moved from the service vehicle to the jobsite, sometimes requiring multiple trips and prolonged carrying.
These exposures rarely occur independently. A technician may simultaneously kneel, bend forward, reach, grip a tool forcefully, and perform repetitive wrenching. This combination can substantially increase overall musculoskeletal demand.
Quantifying the Risk
The Rapid Entire Body Assessment (REBA) was used to quantify ergonomic risk during several of the higher-demand activities observed during the assessment.
Three tasks were identified as presenting particularly significant ergonomic risk:
Meter Repair — REBA Score: 8 (High Risk)
Key risk factors included bending, twisting, reaching, squatting, kneeling, and forceful or repetitive wrench use.
Impact Wrench Use — REBA Score: 10 (High Risk)
Key risk factors included tool vibration combined with bending, kneeling, twisting, and reaching while completing meter installation work.
Pipe Wrench Use — REBA Score: 10 (High Risk)
Key risk factors included forward bending, excessive shoulder positioning, and repetitive wrenching while tightening meter fittings.
Under the REBA interpretation used for the evaluation, scores from 8–10 are classified as High Risk, indicating that the task should be investigated and changes implemented.
Importantly, these scores do not mean that wrenching, kneeling, or meter installation are inherently unsafe. Instead, they demonstrate how multiple physical demands—such as awkward posture, force, repetition, vibration, and environmental constraints—can occur simultaneously and increase overall musculoskeletal exposure.
Why Working Height Matters
One of the most consistent challenges was the height at which work had to be performed.
Several observed meters were positioned approximately one to two feet above ground level. In one repair, the meter was also surrounded by rocks and foliage that further restricted positioning.
When work is this low, technicians generally have several choices: bend from the trunk, squat, kneel, lunge, or sit.
None is necessarily problematic for a short duration. Risk increases when these positions are sustained, repeatedly assumed throughout the day, or combined with forceful work.
This makes seemingly simple interventions valuable. Kneeling pads reduce contact stress. Lightweight seats or dual-purpose tool carriers can provide an alternative to prolonged kneeling or squatting. Changing positions periodically can also distribute physical demands across different muscle groups.
The goal is not to prescribe a single "correct" posture. The goal is to give workers enough options that they do not have to remain in the same high-demand posture for prolonged periods.
Wrenching: A Small Task With Significant Ergonomic Consequences
One of the clearest findings from the evaluation involved wrench use.
Technicians frequently use hand and powered tools to loosen, position, and tighten meter components. When performed close to the ground, wrenching can require substantial shoulder abduction, forward trunk flexion, gripping force, and repetitive upper-extremity movement.
The residential meter installation assessment produced a REBA score of 10 while using a pipe wrench to tighten fittings. The assessment specifically identified repeated wrist, elbow, and shoulder motions together with bending, squatting, kneeling, lunging, neck bending, and reaching.
Several strategies can reduce these demands:
Position the body so the wrenching motion occurs closer to the body's power zone.
Avoid excessive elbow flaring and shoulder abduction when possible.
Generate force through larger muscle groups and the trunk rather than relying exclusively on the arms.
Select tools that allow neutral wrist positions and provide an appropriate grip.
Use gloves that maintain adequate grip without unnecessarily increasing gripping force.
Alternate positions and incorporate brief recovery periods during prolonged or repetitive wrenching.
This is an area where task-specific training is substantially more useful than generic instructions to "use proper body mechanics."
Bringing the Worksite to the Technician
Field technicians often cannot change where the meter is located. They can, however, change how the immediate work area is organized.
Tools placed behind or beside the technician can create dozens of unnecessary reaches and trunk rotations during a single job. A better approach is to establish a primary working zone before beginning the task.
Frequently used tools and components should be positioned within comfortable reach whenever possible. Less frequently used equipment can remain farther away.
This principle should extend to service vehicles. Organized truck storage reduces unnecessary bending, reaching, searching, and handling while also helping technicians bring only the equipment required for a particular job.
The assessment recommended organized truck beds, storage systems that maximize accessible space, and planning tool and component needs before carrying equipment to the work area.
Reduce Carrying Before Teaching Better Carrying
Traditional ergonomics programs often focus heavily on lifting technique. Good body mechanics are important, but eliminating unnecessary manual handling is generally more effective than simply teaching employees how to perform it.
Utility technicians may carry tools, components, meters, and other equipment significant distances from their vehicles. Depending on the job, they may also make several trips when additional tools or components are needed.
Mechanical and organizational solutions can reduce this exposure.
All-terrain carts, dollies, backpacks, appropriately designed totes, tool belts, and vehicle-mounted lifting equipment can all reduce unnecessary carrying. The assessment specifically recommended mechanical aids for heavy or awkward loads, ergonomic hand tools, kneeling mats, better weight-distributing tool carriers, and seating options for prolonged ground-level work.
The broader principle is simple:
Whenever possible, redesign transportation of the load before relying on the worker to tolerate the load more effectively.
Build Ergonomics Into Training
One particularly useful observation from the assessment was that more tenured technicians demonstrated better body mechanics than newer employees.
This presents an opportunity.
Experienced employees often develop practical strategies for positioning themselves, organizing tools, sequencing work, and applying force efficiently. Instead of allowing this knowledge to remain informal, organizations can incorporate it into structured new-hire training.
Experienced technicians can serve as ergonomic ambassadors, demonstrating job-specific techniques rather than teaching ergonomics as an abstract safety topic.
Training can focus on:
Hip hinging, squatting and lunging
Working within the body's power zone
Neutral spine and upper-extremity positioning
Efficient wrenching technique
Tool and material placement
Jobsite setup
Selecting and transporting necessary equipment
Recognizing when to change position or take a brief recovery break
This approach turns ergonomics from an annual training topic into a practical job skill.
Dynamic Warm-Ups and Recovery
The evaluated department already performed pre-shift stretching, providing a strong foundation for a more targeted program.
A field-specific dynamic warm-up should reflect the actual physical demands technicians will encounter that day. For meter technicians, this may include preparation of the shoulders, hands and wrists, trunk, hips, and lower extremities.
Programs should also evolve rather than remain static indefinitely. The assessment recommended reviewing the existing routine to ensure it includes an appropriate combination of dynamic and static movements and periodically changing exercises to address different body regions.
Recovery during the workday is equally important.
Short microbreaks can be particularly valuable following repetitive wrenching, impact-tool use, or extended kneeling and squatting. These breaks do not necessarily require stopping work for extended periods. Changing tasks, standing and moving briefly, or stretching heavily used muscle groups can provide valuable recovery.
A Practical Framework for Utility Ergonomics
An effective field ergonomics program should operate at several levels simultaneously.
1. Improve equipment and tools.
Use mechanical aids, ergonomic hand tools, kneeling protection, portable seating, appropriate carrying systems, and vehicle organization to reduce physical demands.
2. Improve how work is performed.
Teach functional movement, power-zone concepts, wrenching mechanics, worksite setup, and efficient material handling.
3. Improve how work is organized.
Allow reasonable flexibility in work sequencing, encourage recovery following physically demanding tasks, reduce unnecessary trips between vehicles and jobsites, and consider environmental conditions when scheduling demanding work.
4. Use experienced employees as a resource.
Capture the techniques experienced technicians have developed and incorporate them into onboarding and continuing education.
5. Encourage early reporting.
Employees should be able to report discomfort before it becomes an injury. Early identification provides an opportunity to modify tasks, tools, or work practices before a more significant musculoskeletal disorder develops.
6. Measure and reassess.
Ergonomics should be an ongoing process rather than a one-time assessment. Organizations should establish action plans, implement selected improvements, gather employee feedback, and reassess higher-risk tasks to determine whether interventions are working. The assessment itself recommends creating an action plan with timelines followed by onsite reassessment after ergonomic initiatives are implemented.
Preparing for Large-Scale Operational Changes
Ergonomic planning becomes particularly important when the volume of repetitive field work is expected to increase.
In this case, the utility was preparing for an exchange program involving replacement of more than 100,000 meters. Technicians typically completed approximately 8–15 work orders per day, although the complexity and duration of individual jobs varied.
A large-scale replacement program can magnify exposures that may be manageable when they occur intermittently. Repeated meter handling, kneeling, wrenching, carrying equipment, and working at low heights can accumulate across hundreds or thousands of installations.
That makes the period before a major deployment an ideal time to evaluate tools, refine training, test transportation solutions, optimize work practices, and establish mechanisms for early reporting.
Ergonomics can then become part of operational planning rather than a response to injuries after they occur.
Conclusion
Utility field work will always contain physical demands that cannot be completely engineered out of the job. Meters will remain close to the ground. Terrain will vary. Technicians will need to use tools, handle equipment, and adapt to environments they do not control.
That does not mean ergonomic risk cannot be substantially reduced.
The strongest approach combines better equipment, thoughtful jobsite organization, task-specific body mechanics, improved material transportation, dynamic warm-ups, recovery opportunities, experienced-worker knowledge, and continuous evaluation.
Perhaps most importantly, effective utility ergonomics recognizes that the objective is not to teach employees one "perfect" way to work. It is to provide workers with better options for accomplishing demanding tasks while reducing unnecessary stress on the body.
For organizations facing aging infrastructure, workforce challenges, or large-scale meter replacement initiatives, integrating ergonomics into field operations can help protect employees while supporting safer, more sustainable performance.
