Stop before starting
Stop for tension increase, cable stall, shifted rollers, moving drum/puller support, signal loss or entry into the tension line or inside bend. Hold access and connection release until residual energy and vertical support are verified.
1. Legal and technical scope
| Basis | Scope and limits |
|---|---|
| OSHA 1926.416 | Construction protection from actual electrical hazards. |
| OSHA 1926.300 | Hand/power-tool safeguards within scope. |
| Southwire Power Cable Installation Guide | Manufacturer guidance on route, pulling tension, bend pressure and rollers; actual cable-specific limits required. |
This construction reference uses 1926.416 for electrical exposures, 1926.417 for applicable circuit lockout/tagging and 1926.300 for tool safeguards. Resolve actual equipment and access requirements and State Plan rules. Southwire guidance explains route forces; use the actual cable and pulling-method limits, not a universal tension, bend radius, sidewall-pressure or lubricant value.

4. Fictional scenario and failure mechanisms
This illustration provides educational context. It is not an actual incident photograph or evidence of equipment suitability; any AI-generated depiction is illustrative only.
The scenario and record comparisons are fictional teaching examples, not records of real incidents, measurements, inspections, signatures or approvals.
| Stage | Fictional situation |
|---|---|
| Initial situation | A fictional feeder pull passes several bends. |
| Changed condition | A roller stops turning freely, cable progress slows and tension rises. |
| Failure path | The crew continues because the displayed value is below the set maximum. |
| Possible outcome | Local damage, connector failure or recoil could develop. |
| Prevention barrier | Stop the pull, prevent restart, support the cable and control residual energy before checking the route and defining the required damage assessment and restart conditions. |
Failure mechanisms
The puller reading does not establish the condition at every bend. Bend radius, cable arrangement and friction affect local forces. Moving one roller can change sidewall pressure and support even when the measured tension remains below its limit.
A stopped puller can leave elastic tension in the rope and cable and gravity load in vertical runs. Before approaching a jam or removing a connector, separately establish restart prevention, access exclusion, cable support and the approved energy-release sequence.
Clearing an obstruction does not establish cable fitness for service. Preserve the time, location and tension trend and assess the affected segment. External appearance or one electrical test cannot prove the absence of every internal or mechanical defect.
Work sequence: Review route and forces → Set drum and puller → Inspect cable and rollers → Trial pull and signals → Pull and monitor bends → Secure and protect ends → Hold obstruction → Inspect and hand over. This is a teaching flow, not a device drawing or a complete operating procedure.
5. Conditional decisions and common errors
| Situation | Required action | Evidence | Proceed when |
|---|---|---|---|
| Tension rises or cable stalls | Stop pulling | Trend, roller and route evidence | Cause corrected |
| Roller moved | Review changed geometry | Bend radius and local force review | Route accepted |
| Puller stopped | Hold access to loaded path | Isolation, support and residual load | Energy controlled |
| Cable reaches destination | Inspect and identify | Damage history and end records | Handover accepted |
Similar observations, different decisions
The scenario and record comparisons are fictional teaching examples, not records of real incidents, measurements, inspections, signatures or approvals.
| Observation | Insufficient conclusion | Required distinction |
|---|---|---|
| Tension below limit | One measured value | Local bend condition separate |
| Puller off | Drive stopped | Stored tension may remain |
| Jacket looks intact | External inspection | Internal condition unproved |
6. Roles and responsibilities
| Role | Responsibility |
|---|---|
| Work supervisor | Confirm cable and pulling method and the task scope, resources, interfaces and stop authority. |
| Qualified technical reviewer | Review stand and ground, model limits, compatibility and unresolved technical conditions within assigned competence. |
| Work crew | Apply the listed controls, report changes and stop when evidence or safeguards are missing. |
| Inspector / assessor | Record actual recoil and bend boundary and other relevant checks; do not mark unverified conditions as accepted. |
| Handover authority | Reconcile jacket and tension history, restrictions and outstanding actions before the next task. Role labels do not establish a legal credential. |

7. Hold points and record comparison
| Hold point | Evidence before release | Actual approval |
|---|---|---|
| HP-0 Scope | Reviewing a new feeder route, setting the drum and puller, checking pulling attachments and rollers, making a controlled trial and continuous pull, securing and sealing ends and handing over inspection records. | |
| HP-1 Set drum and puller | Stand and ground; Spindle and braking; Puller anchorage; Exclusion and escape | |
| HP-2 Trial pull and signals | Tension and roller behavior; Drum braking; Hands feet exclusion; Full-route communication | |
| HP-3 Hold obstruction | Fault time and tension; Cable roller condition; Isolation record; Residual-load control | |
| HP-4 Inspect and hand over | Jacket and tension history; Circuit end identification; Sealed ends and route; Held segments and next work |
Hold points are internal project checks. They are not universal statutory permits and do not grant work permission. Reassess after defects, changed conditions and shift changes.
Record comparison
The scenario and record comparisons are fictional teaching examples, not records of real incidents, measurements, inspections, signatures or approvals.
The boxes are static record prompts, not interactive or saved approvals. A tick does not establish suitability or permission to restart. Record the evidence, person, time and unresolved issues; retain the change history.

Stop work
Stop for tension increase, cable stall, shifted rollers, moving drum/puller support, signal loss or entry into the tension line or inside bend. Hold access and connection release until residual energy and vertical support are verified.
Emergency response
Stop and secure the puller, clear recoil and cable-fall zones and activate site emergency response. Do not enter a manhole or touch adjacent electrical equipment for improvised rescue; qualified responders establish the safe route and energy condition.

Can pulling continue below the tension limit despite a jam?
No. Stalling, shifted rollers, unusual force or support movement are stop conditions independent of the displayed limit.
Can the pulling eye be disconnected immediately after stopping?
Only after restart prevention, cable support and the approved residual-energy release are verified.
Does completed pulling authorize energization?
No. Transfer identification and inspection evidence to separately authorized termination, testing and energization work.
Has a professional verified or approved this document?
No. Public sources and editorial, layout and consistency checks were reviewed using AI. No site inspection or professional technical approval has been performed. Obtain appropriate professional review before use.
