Cable Pulling JHA (Job Hazard Analysis / Activity Hazard Analysis)
Updated 2026-06-23
A Cable Pulling JHA (Job Hazard Analysis / Activity Hazard Analysis) is the plan that keeps the electrical crew from being struck by a parting pull-rope, wearing out their backs feeding heavy cable, or being caught at the pinch points where cable enters conduit. Pulling cable through conduit, duct banks, and cable trays generates high rope and cable tension, demands heavy repetitive handling, and often takes place in manholes, vaults, and other confined spaces. This guide walks through building a Cable Pulling JHA that names the line-tension, ergonomic, and confined-space hazards and assigns the rigging, handling, and entry controls that hold up in the field.
Why cable pulling needs its own JHA
Pulling cable means moving heavy conductors through conduit runs, duct banks, and cable trays, often over long distances and around bends that build up enormous friction. The pull is driven by hand, by mechanical pullers, or by tuggers, and the pulling rope and cable can be under very high tension. If a rope, swivel, or cable parts under that tension, it recoils with enough force to cause serious injury. Cable pulling also involves heavy repetitive lifting and feeding, pinch points where cable enters conduit, and frequently takes place in manholes and vaults that are confined spaces. The combination of stored tension, ergonomics, and confined-space entry justifies a dedicated JHA.
Breaking cable pulling into steps
The steps for a Cable Pulling JHA follow the pull from setup to dress-out:
- Plan the pull — route, tension, lubrication, and equipment
- Verify the conduit/raceway is de-energized and safe to access
- Set up the cable reels, feeder, puller, and rigging
- Position crew at the feed end, pull end, and any intermediate points
- Rig the pulling rope, swivel, and grip to the cable
- Pull the cable, monitoring tension and communication
- Manage manhole and vault entries as confined spaces
- Dress, terminate, and clean up
Each step carries a hazard, and the tension management and the confined-space entries are where the serious risks concentrate.
The hazards step by step
Line tension and recoil
The pulling rope and cable can be under very high tension, especially on long pulls with multiple bends. A rope, swivel, grip, or attachment that fails recoils violently and can strike workers at the pull end. The controls are using rope and rigging rated for the calculated pull tension, inspecting the rope, swivel, and grip before the pull, keeping workers out of the direct line of the rope where recoil would travel (out of the "line of fire"), using a tension-monitoring puller where available so the pull is stopped if tension spikes, and clear communication between the feed and pull ends so the pull stops immediately if something binds.
Ergonomic strain
Feeding and pulling heavy cable, lifting reels, and handling conductors is heavy repetitive work that strains backs and shoulders. The controls are mechanical pullers and tuggers rather than hand-pulling heavy cable, cable lubricant to reduce the required force, reel stands and jacks for handling reels, team lifts, and rotating the crew through the most strenuous positions.
Confined-space entry
Manholes, vaults, and pull pits where cable is fed and routed are frequently confined spaces with atmospheric, engulfment, and access hazards. The controls are evaluating and, where required, permitting these spaces as confined-space entries — atmospheric testing, ventilation, an attendant, and a rescue plan — before workers enter to feed or guide cable.
Pinch points and electrical hazards
Cable entering conduit and passing over rollers and sheaves creates pinch points, and pulling cable into a system that could be energized, or near energized equipment, adds electrical hazards. The controls are keeping hands clear of conduit entries and rollers during the pull, and confirming the raceway and any nearby equipment are de-energized and, where appropriate, locked out.

Tension management and the line of fire
A Cable Pulling JHA centers on managing tension and keeping workers out of the line of fire. The pull builds tension that the crew cannot always see, and the failure point — a parted rope or grip — recoils along the line of the pull. The controls are rated rigging, inspection before the pull, a tension-monitored puller that stops if the force spikes, and positioning workers out of the path the rope would travel if it let go. Combined with clear communication so the pull stops the instant something binds, this manages the hazard that makes cable pulling more dangerous than it looks. Where the pull involves manhole and vault entries, the confined-space controls apply on top of the pulling controls.
From the field: what actually goes wrong
In fourteen years across federal, heavy civil, and industrial projects, the cable-pulling hazards that cause the worst injuries are the recoil from a failed pull and the confined-space entries that get treated casually. The recoil happens on long, high-tension pulls when a rope, swivel, or grip parts and snaps back along the line of the pull — and a worker standing in that line at the pull end takes the recoil. The control is positioning the crew out of the line of fire and using rigging rated for the actual tension, which on long pulls with multiple bends can be far higher than the crew estimates. A tension-monitored puller that stops when the force spikes prevents the overload in the first place.
The confined-space hazard is the one that gets normalized because manholes and vaults are routine to the electrical crew. But a vault with a hazardous atmosphere is a permit-required confined space whether or not the crew thinks of it that way, and the second-rescuer fatality pattern applies just as much here as anywhere. On the projects I have run, the discipline that matters is evaluating every manhole and vault entry against the confined-space requirements — testing, ventilation, an attendant, and a rescue plan — rather than treating it as just another pull pit. The ergonomics round it out: hand-pulling heavy cable wrecks backs, and mechanical pullers with lubricant are the control. The JHA that manages the tension, keeps the crew out of the line of fire, and treats the vaults as confined spaces is the one that keeps the cable crew safe.
The bottom line
A strong Cable Pulling JHA names the line-tension, the ergonomic, and the confined-space hazards with specific controls — rated rigging and a tension-monitored pull, workers out of the line of fire, mechanical pullers to spare the crew, and confined-space controls for manholes and vaults. Cable pulling looks like simple labor and carries hidden tension and entry hazards. The JHA that manages the recoil and the entries is the one that protects the electrical crew.
Frequently asked questions
What is the line-of-fire hazard in cable pulling?
On long, high-tension pulls a rope, swivel, or grip can part and recoil violently along the line of the pull, striking workers at the pull end. The control is positioning the crew out of the path the rope would travel if it let go, plus rated rigging and a tension-monitored puller that stops if the force spikes.
Are manholes and vaults confined spaces during cable pulling?
Frequently, yes. Manholes, vaults, and pull pits often have atmospheric, engulfment, and access hazards, and they must be evaluated and, where required, permitted as confined-space entries — with testing, ventilation, an attendant, and a rescue plan — before workers enter to feed or guide cable.
How do you reduce the force needed to pull cable?
Cable lubricant reduces the friction and required pulling force, and mechanical pullers or tuggers replace hand-pulling heavy cable. This protects the crew from both the overtension failures and the ergonomic strain of feeding and pulling heavy conductors.
Should the raceway be de-energized before pulling?
Yes. The raceway and any nearby equipment are confirmed de-energized and, where appropriate, locked out before pulling, to remove the electrical shock hazard of pulling cable into or near energized systems.
