Earthmoving Operations JHA (Job Hazard Analysis / Activity Hazard Analysis)
Updated 2026-06-23
An Earthmoving Operations JHA (Job Hazard Analysis / Activity Hazard Analysis) is the plan that keeps the crew and the equipment operators safe during mass earthmoving — the cut, fill, grading, and hauling that move large volumes of soil with dozers, scrapers, graders, loaders, and haul trucks. Earthmoving puts large, fast, heavy equipment in continuous motion across a site, often on slopes and haul roads, around workers on foot and other machines. This guide walks through building an Earthmoving Operations JHA that names the struck-by, rollover, and blind-spot hazards and assigns the traffic, terrain, and communication controls that hold up in the field.
Why earthmoving operations need their own JHA
Earthmoving moves large volumes of soil to shape a site — excavating cut areas, placing and compacting fill, grading to design, and hauling material. The work uses fleets of large equipment — dozers, scrapers, motor graders, loaders, excavators, and haul trucks — operating continuously, often at speed on haul roads and on graded slopes. The hazards are dominated by the equipment: struck-by and run-over of workers on foot and at the interface between machines, rollover on slopes and fill edges, the large blind spots of the equipment, and collisions between machines on haul roads. The scale and continuous motion of the equipment fleet justifies a dedicated JHA focused on managing the traffic and the terrain.
Breaking earthmoving operations into steps
The steps for an Earthmoving Operations JHA follow the operation:
- Plan the earthmoving — cut/fill areas, haul roads, and traffic pattern
- Survey terrain, slopes, utilities, and overhead lines
- Establish haul roads, traffic control, and communication
- Operate equipment for cut, fill, grading, and hauling
- Manage the interface between equipment and workers on foot
- Operate on slopes and at fill edges within limits
- Maintain haul roads and manage dust and visibility
- Coordinate the equipment fleet throughout
Each step carries a hazard, and the traffic management and the slope/edge operation are where the most serious risks concentrate.
The hazards step by step
Struck-by and run-over
The dominant earthmoving hazard is a worker on foot struck or run over by equipment, and collisions between machines. Large equipment moves continuously, often in reverse, with limited visibility. The controls are minimizing workers on foot in the equipment operating area, separating foot and equipment traffic, spotters and positive communication where workers must be near equipment, backup alarms and backing plans, high-visibility apparel, and a haul-road traffic pattern that manages machine-to-machine interactions. Ground workers maintain eye contact and positive communication with operators before approaching.
Rollover on slopes and fill edges
Earthmoving equipment operates on graded slopes, fill embankments, and at the edges of fills and cuts, where rollover is a leading hazard. The controls are operating within the equipment's slope limits, seatbelts and rollover protective structures, keeping a safe distance from fill edges and the edges of excavations (which can give way), and operators surveying the terrain. Edge-of-fill operation gets particular caution because the edge can collapse under the machine.
Blind spots and visibility
Earthmoving equipment has large blind spots, and dust on haul roads reduces visibility. The controls are cameras, mirrors, and spotters for blind areas, dust control on haul roads, and operators and ground workers managing the limited sightlines. Workers never assume an operator can see them.
Slope stability, utilities, and overhead lines
Cut slopes and stockpiles can fail, buried utilities can be struck, and equipment reaches overhead lines. The controls are managing slope and stockpile stability, locating utilities before disturbing the ground, and maintaining clearance from overhead power lines.

|---|---|---|---|
| Plan traffic | Struck-by / collision | Haul-road traffic pattern, separate foot and equipment | OSHA 1926.602 |
| Survey terrain | Utility / line strike | Locate utilities, identify slopes and overhead lines | OSHA 1926.651 / 1926.1408 |
| Workers near equipment | Run-over | Spotters, positive communication, hi-vis, minimize foot traffic | OSHA 1926.601 |
| Operate on slopes | Rollover | Within slope limits, seatbelt, ROPS, distance from edges | OSHA 1926.1000 |
| Blind spots | Struck-by | Cameras, mirrors, spotters, dust control | OSHA 1926.601(b) |
| Maintain haul roads | Collision / loss of control | Road maintenance, dust and visibility control | OSHA 1926.602 |
Traffic management and edge operation
An Earthmoving Operations JHA centers on managing the equipment traffic and controlling operation at slopes and edges. The traffic management addresses the dominant struck-by hazard — a fleet of large equipment in continuous motion around workers on foot and around each other — through separation of foot and equipment traffic, a haul-road traffic pattern, spotters and communication, and minimizing workers on foot in the operating area. The edge and slope operation addresses the rollover hazard — equipment working on graded slopes and at the edges of fills where the ground can give way — through slope limits, seatbelts and ROPS, and safe distance from edges. A JHA built on traffic management and safe edge operation controls the struck-by and rollover hazards that dominate mass earthmoving.
From the field: what actually goes wrong
In fourteen years across federal, heavy civil, and industrial projects, earthmoving is dominated by the equipment, and the fatalities are workers struck or run over and operators killed in rollovers. The struck-by and run-over incidents happen at the interface between the equipment fleet and workers on foot — a worker in the path of a backing scraper or haul truck, in the blind spot of a dozer, or between machines on a haul road. The control philosophy is separation: keep workers on foot out of the equipment operating area as much as possible, and where they must be there, use spotters, positive communication, and high-visibility apparel, with the worker initiating contact with the operator before approaching. The haul-road traffic pattern manages the machine-to-machine collisions.
The rollovers are the operator-killing hazard, and earthmoving creates the conditions for them — equipment working on graded slopes, on fill embankments, and at the edges of fills and cuts where the ground can collapse under the machine. On the projects I have run, the controls are operating within slope limits, wearing the seatbelt so the ROPS works, and keeping a safe distance from fill edges and excavation edges that can give way. The blind spots and haul-road dust reduce visibility, so cameras, spotters, and dust control matter. The JHA that separates the traffic, manages the haul roads, and controls slope and edge operation is the one that gets the earth moved without a struck-by or a rollover.
The bottom line
An Earthmoving Operations JHA names the struck-by, the rollover, and the blind-spot hazards with specific controls — separation of foot and equipment traffic with a haul-road pattern and spotters, slope limits and seatbelts for rollover protection, and visibility controls for the blind spots and dust. Earthmoving is dominated by a fleet of large equipment in continuous motion. The JHA built on traffic management and safe edge operation is the one that protects the crew and operators.
Frequently asked questions
What is the dominant earthmoving hazard?
Workers on foot struck or run over by equipment, and collisions between machines. A fleet of large equipment moves continuously, often in reverse with limited visibility, so the control philosophy is separating foot and equipment traffic, using spotters and positive communication, and minimizing workers on foot in the operating area.
How are rollovers prevented in earthmoving?
By operating within the equipment's slope limits, wearing seatbelts so the rollover protective structure (ROPS) works, keeping a safe distance from fill edges and excavation edges that can give way, and having operators survey the terrain. Earthmoving equipment works on graded slopes and at the edges of fills where rollover is a leading hazard.
Why are blind spots a major earthmoving hazard?
Earthmoving equipment has large blind spots, and haul-road dust further reduces visibility, so operators often cannot see workers on foot close to or behind the machine. Controls are cameras, mirrors, and spotters for blind areas, dust control, and ground workers never assuming an operator can see them — making eye contact and positive communication before approaching.
How is the equipment fleet coordinated?
Through a haul-road traffic pattern that manages machine-to-machine interactions, positive communication, and road maintenance with dust and visibility control. Coordinating the continuous motion of multiple large machines prevents the collisions and struck-by incidents that the dense equipment operation creates.
