JHA for electrical maintenance: a US de-energized-work template
Use this JHA to plan electrical maintenance around a verified de-energized state. Identify the equipment, every source of electrical and stored energy, who is qualified to isolate it, how absence of voltage will be verified, what remains energized nearby, and the condition for restoring power. This form is a hazard-analysis prompt, not an electrical switching instruction, lockout/tagout procedure, arc-flash calculation, permit for energized work or substitute for a qualified electrician. Stop if the equipment, circuit, drawings or isolation boundary cannot be confirmed.
For general-industry electrical work, OSHA 1910.333 requires exposed live parts to be de-energized before an employee works on or near them unless the employer can demonstrate one of the stated exceptions. De-energized parts not locked/tagged as required are treated as energized. OSHA 1910.147 controls unexpected startup or release of stored energy during general-industry servicing/maintenance, but expressly excludes construction work from its scope. Construction electrical work invokes relevant Part 1926 provisions, including 1926.416. Check the actual task and State Plan rather than labelling every job “LOTO under 1910.147.”
The existing US JHA guide covers how to construct a JHA generally. This page owns the electrical maintenance worksheet and its work authorization handoff.
Job and authorization details
| Field | Site-specific entry |

| Exact maintenance scope; work that is excluded | |
| Employer, supervisor and qualified electrical person(s) | |
| Operating equipment owner and person authorizing outage | |
| Federal/State Plan standard and site procedure | |
| Drawings, labels and single-line diagram verified by | |
| Normal supply, alternate/backfeed and stored-energy sources | |
| Adjacent energized equipment and boundary | |
| Equipment-specific isolation/lock/tag procedure reference | |
| Absence-of-voltage test method/equipment and qualified tester | |
| PPE/arc and shock assessment reference | |
| Emergency response, rescue and first-aid arrangements | |
| Planned outage and restoration approvers | |
| Crew briefing date, revision and signatures |
Work hold: no exposure to conductors or equipment internals until the qualified person has confirmed the correct equipment, isolated every source, applied the applicable energy-control process, addressed stored energy and verified absence of voltage with suitable test equipment. A switch position, indicator lamp or work-order note alone is not verification. If this cannot be achieved, stop and take the task through a separate qualified energized-work determination and procedure; do not edit this JHA to casually authorize live work.
Fillable task-step JHA
Complete the third and fourth columns for the actual equipment. Record Pass / Action / Hold, the person accepting the control, and any permit or separate procedure reference.
| Step | Hazard and consequence | Control/evidence to complete | Release or stop decision |
|---|---|---|---|
| 1. Plan and walk down | Wrong equipment or outdated drawing; exposure to another circuit. | Confirm equipment ID in field, work scope, diagram, supply routes, operating impact and adjacent equipment. | Qualified electrical lead: HOLD if identity uncertain. |
| 2. Coordinate outage | Unexpected energization or disruption to life-safety/critical operations. | Notify affected operations; confirm shutdown window, backup systems and authority to isolate. | Equipment owner/site supervisor. |
| 3. Assess electrical and other energy | Shock, arc, mechanical movement, battery/capacitor, pneumatic or hydraulic release. | Identify all sources and stored energy; select applicable equipment-specific control procedure and protective boundary. | Qualified lead: HOLD until sources mapped. |
| 4. De-energize and secure | Wrong disconnect; remote/automatic restart; backfeed. | Qualified person performs approved switching/isolation and lock/tag sequence; each affected worker's protection addressed under the applicable procedure. | Qualified lead: HOLD until secured. |
| 5. Verify safe state | Residual or unexpected voltage; defective tester. | Use suitable, properly rated test equipment and employer procedure to verify absence of voltage at points of exposure; control remaining live parts. | Qualified tester: HOLD on any unexpected result. |
| 6. Perform maintenance | Contact with nearby energized part, stored energy, sharp parts, dropped objects or unsuitable tools. | Maintain barriers/boundaries, suitable tools and PPE, work positioning and housekeeping; follow task method. | Crew lead; stop on deviation. |
| 7. Inspect and restore | Tool left inside, guard missing, worker still exposed, unexpected startup. | Check work, remove people/tools, reinstall barriers, account for locks/tags under procedure, obtain operating-owner authorization, warn affected people and re-energize by approved sequence. | Qualified electrical lead and operating owner. |
| 8. Test and close | Failed repair, changed protection or incomplete records. | Functional test by qualified people, document results, defects, as-left state, handover and follow-up. | Equipment owner signs acceptance or holds equipment. |
Do not copy this table as the equipment's switching sequence. Device numbers, voltage, isolation points, test points and arc/shock boundaries belong in the site-controlled electrical procedure prepared and reviewed by qualified people.
The legal and technical boundaries that matter
De-energize unless the rule's exception is actually justified
Under 1910.333(a)(1), an employer must de-energize exposed live parts before work on or near them unless it can demonstrate increased/additional hazards or infeasibility due to equipment design or operational limitations. Schedule pressure and convenience are not themselves an exception. If an exception is genuinely invoked, this de-energized-work template is inadequate: a qualified electrical specialist must assess the live-work methods, boundaries, equipment, PPE and authorization under the applicable standard and site rules. Do not publish a generic “live test” recipe.
Isolation and zero-energy verification are separate decisions
OSHA 1910.333(b) has its own electrical lock/tag and verification sequence. It explains when procedures meeting portions of 1910.147 may be deemed to meet certain electrical provisions, with additional conditions. The standards are not interchangeable labels; the qualified person must select the correct process for the task. Stored energy, backfeeds and induced voltage may persist after a disconnect opens. Verify by the method required for the equipment and work.
Construction and utility work are different scopes
This is primarily a general-industry fixed-equipment maintenance worksheet. 1910.147 excludes construction; 1926.416 addresses construction electrical exposure, and power generation/transmission/distribution has specialist provisions. If the job is construction, line work or utility-controlled equipment, have a qualified person choose the correct standard and replace the task controls. Do not republish this unchanged as a universal electrical JHA.
Scenario: replacing a failed motor control component
A maintenance team plans to replace a component in a production panel. The work order names panel M-4, but the field label is faded and the latest drawing shows a backup supply. The team does not open the panel based on the work order alone. A qualified electrical lead confirms panel identity and the backup source, coordinates the outage with production, reviews the arc/shock assessment, performs the controlled isolation and verifies the safe state. If an adjacent section remains energized, its exposure boundary is separately controlled. The team repairs, accounts for tools and people, restores protection, then follows the approved re-energization process. If a required test can be performed only while energized, that test requires a separate qualified live-work assessment; this JHA's maintenance steps do not authorize it.
Briefing, change and close-out record
| Record | Entry |
|---|---|
| Task revision and date | |
| Qualified lead and affected workers briefed | |
| Equipment identity/drawing and sources confirmed | |
| Isolation procedure and lock/tag record location | |
| Absence-of-voltage verification and tester | |
| Adjacent live boundary/PPE controlled | |
| Work released by / time | |
| Change, stop and restart decision | |
| Restoration test, as-left state and owner acceptance |
Reassess when the equipment, supply, task, people, conditions or drawings change. Retain the current JHA with the separate equipment procedure, permits, drawings and as-left records under your site rules. Digital sign-off can help show who approved which version, but it cannot prove the circuit was physically isolated or tested.
What a site-specific version must add
Insert the actual electrical single-line, device identifiers, energy sources, lock/tag and test method, boundaries, arc/shock assessment, work scope, operating impacts, critical-system arrangements, rescue and restoration sequence. Require qualified electrical review and any engineer/owner approval. No generic form should offer numeric PPE, approach distances or test instructions without the equipment data and applicable standards.
The observed Complys US OSHA software page markets JHA records but does not prove implementation. Verify the exact US money route and current plan before CTA. Do not say Complys isolates equipment, evaluates arc flash, confirms zero voltage, authorizes live work or guarantees OSHA compliance. A safe CTA is: Ask Complys to demonstrate how its current US workflow stores the completed, qualified-person-approved JHA and tracks a changed version.
