Lockout tagout for electricians, in short: identify every source, shut off the load, open the disconnect, put your own lock and tag on it, release stored energy, then test for absence of voltage with a tester you check before and after. OSHA 1910.333 covers electrical work, and lockout ranks #3 on OSHA's FY2026 most-cited list. A serious violation can cost up to $16,550.

Most electrical shops lock out by habit, and most of them couldn't hand an OSHA inspector a written procedure, a training record or last year's inspection. This guide sorts out which OSHA rules apply to electrical work, lists the steps, gives you a procedure for a residential panel job to adapt, and covers the paperwork. We checked the regulations on eCFR and osha.gov in October 2026. It's general information, not legal advice or a substitute for training; your state may run its own OSHA plan.

Key takeaways

  • Electrical work on conductors falls under OSHA 1910.333(b) (general industry) or 1926.417 (construction), not only the machine lockout rule, 1910.147.
  • One lock per person, on every disconnecting means. A switch, push button or interlock alone doesn't count.
  • Test, don't trust. A qualified person verifies absence of voltage with a tester checked on a known source before and after.
  • Write it down. 1910.333 requires written procedures; the rule's own text can serve as yours.
  • Train and certify each employee, and retrain when jobs, equipment or procedures change.
  • Penalties: up to $16,550 per serious violation and $165,514 per willful or repeated one (OSHA, October 2026).

Which OSHA lockout rule applies to electricians: 1910.147, 1910.333 or 1926.417?

It depends on the work. OSHA's machine lockout standard, 1910.147, says electrical hazards from work on, near or with conductors or equipment in electric-utilization installations are covered by Subpart S instead, which is where 1910.333 sits. And OSHA treats “construction, alteration, and/or repair” as construction work (1910.12), covered by Part 1926.

RuleCoversKey lockout requirements
1910.333(b)General industry electrical work on deenergized partsWritten procedures; disconnect all sources; lock and tag every disconnecting means; release stored energy; qualified person tests for absence of voltage; set order to reenergize
1910.147Servicing machines and equipment where unexpected startup or stored energy can hurt someoneEnergy control program, written procedures, standard devices, annual inspection, training and certification
1926.417Construction work on circuitsTag deactivated controls; make deenergized circuits inoperative, with tags at every point they could be energized; tags identify the circuit

A note in 1910.333 says a program that meets 1910.147(c) through (f) also satisfies its lockout paragraph, as long as it covers electrical hazards, adds an extra measure when you use a tag without a lock, and has a qualified person test for absence of voltage. Many shops write one program that meets both.

What are the lockout tagout steps for electrical work?

The steps combine 1910.333(b)(2), the 1910.147(d) sequence and NFPA 70E's process for an electrically safe work condition. NFPA 70E numbers that process 120.5 in the 2021 edition and 120.6 in the 2024 edition, so check the one your customers or insurer require.

  1. Prepare. Identify every source from the panel schedule, drawings and a walk-around: utility service, solar, batteries, generators and anything that could backfeed.
  2. Notify the homeowner, the facility contact or other trades who could be affected.
  3. Shut down the load with its normal controls before opening the disconnect.
  4. Open the disconnecting means for each source. Push buttons, selector switches and interlocks can't be the only means.
  5. Apply your lock and tag to each disconnecting means. Each person working puts on their own lock.
  6. Release stored energy: discharge capacitors, and block or relieve stored mechanical energy.
  7. Verify absence of voltage. Check the tester on a known source, test phase to phase and phase to ground, then check the tester again.
  8. Do the work, and retest if you leave the job or conditions change.
  9. Release: remove tools and jumpers, warn everyone to stand clear, each person removes their own lock, confirm everyone is clear, then reenergize.

OSHA requires the before-and-after tester check in 1910.333 for circuits over 600 volts; NFPA 70E's process calls for it on absence-of-voltage tests generally. Doing it every time costs seconds and catches a dead meter.

What does a written lockout procedure look like for a residential panel job?

Here's a procedure for replacing a branch breaker or adding a circuit in a single-family panel. Adapt it, have a qualified person review it, and keep it with your safety program. Remember that opening the main breaker doesn't deenergize the service conductors or the main's line-side terminals; work there needs the utility to disconnect.

StepActionRecord
ScopeBranch circuit or panel bus work, 120/240 V single-phase residential panelJob number, address, panel location
SourcesUtility service; check for solar, battery, generator inlet or transfer switch and label eachSources found
NotifyTell the homeowner which circuits go dead and for how long; ask about medical equipment or freezersWho was told, time
Shut downTurn off loads on the affected circuits, then open the branch breakers and the main breakerBreakers opened
Lock and tagBreaker lockout on the main, personal padlock and tag (name, company, phone, date) on each; lock the generator and solar disconnects tooPhoto of each lock
Stored energyCheck connected equipment for capacitors; discharge or wait as the maker directsDone / not applicable
VerifyCheck tester on a known source; test each bus and conductor phase to phase and to ground; recheck testerReadings, tester ID
Line sideTreat the main's line-side lugs and service conductors as live; cover or stay clearCover used
ReleaseRemove tools, replace the dead front, warn the homeowner, remove own lock, close main, then branchesTime restored

1910.147 lets you skip a written procedure only when all of eight conditions hold, including a single, easily identified source, no stored energy, one lock under the worker's exclusive control and no prior accidents from unexpected reenergizing. A panel with solar or a generator fails that test, so write it down.

What lockout devices does each electrician need?

  • Personal padlocks, keyed so only the worker's key opens them, standardized by color or shape across the shop.
  • Breaker lockouts for single-pole, double-pole and the panel brands you see most, plus a universal clamp.
  • Tags that identify who applied them and resist weather; tag attachments rated to at least 50 pounds.
  • A group hasp or lock box for crew jobs.
  • A voltage tester rated for the work and a known source or proving unit to check it.

What training and annual inspections does OSHA require?

Under 1910.147(c)(6) and (c)(7), the paperwork comes down to four things:

RequirementWhat to doWhat to keep
Training (c)(7)(i)Authorized employees learn to recognize energy sources and control methods; affected employees learn the purpose; others learn not to touch locked equipmentEach name and training date
Tag limits (c)(7)(ii)Teach that tags are warnings, not physical restraintsPart of the training record
Retraining (c)(7)(iii)When jobs, equipment or procedures change, or an inspection finds gapsNew date per person
Annual inspection (c)(6)At least once a year, an authorized employee other than the one using the procedure watches it in use and corrects problemsEquipment, date, employees, inspector

For crews, 1910.147(f)(3) requires a group procedure where one authorized person is responsible and each worker puts their own lock on the group device. Only the worker who put a lock on removes it; someone else may remove it only under a documented procedure, after confirming the worker isn't on site and making reasonable efforts to reach them.

How much does a lockout tagout violation cost?

Up to $16,550 per serious or other-than-serious violation, $16,550 per day for failure to abate, and $165,514 per willful or repeated violation, per OSHA's penalties page in October 2026. OSHA adjusts these for inflation each year, and states that run their own plans must be at least as strict. Lockout (1910.147) ranked third on OSHA's preliminary FY2026 list of most-cited standards, behind fall protection and hazard communication.

The bigger cost is a burn or a death. Build the time into the job: our guides on pricing electrical work and panel upgrade pricing show where setup time goes in a flat rate. Jobs that add a source need extra care; see generator installation pricing and EV charger installation pricing.

Where CrewRobin fits

CrewRobin doesn't track lockout training, certifications or annual inspections; keep those in your safety program. What it can do is put the procedure in front of the tech on every job: each job's checklist is built from your checklists per job type, and technicians tick the steps off in My day, the phone-friendly web page, with a photo per step. Add “lock and tag applied” and “absence of voltage verified” to your panel and circuit job types, and the photos stay with the job. See how it works for electricians.

Frequently asked questions

Does OSHA 1910.147 apply to electricians?

Partly. 1910.147 covers servicing machines and equipment, but says electrical hazards from work on or near conductors are covered by Subpart S, mainly 1910.333(b). Construction work on circuits falls under 1926.417. Many shops write one program that meets both 1910.147 and 1910.333.

What are the steps of lockout tagout for electrical work?

Identify every source, notify affected people, shut down the load, open each disconnecting means, apply your lock and tag, release stored energy, and verify absence of voltage with a tester checked before and after. Release in a set order when the work is done.

Can an electrician use a tag without a lock?

Only if a lock can't be applied or you can show a tag gives equal safety, and 1910.333 then requires at least one more measure, such as removing a fuse or blocking a switch.

How often is lockout tagout training required?

OSHA requires initial training and certification, then retraining whenever job assignments, equipment or procedures change or an inspection finds gaps. Each procedure must be inspected at least once a year.

What is the OSHA fine for lockout tagout?

OSHA's penalties page lists up to $16,550 per serious violation and $165,514 per willful or repeated violation as of October 2026. Amounts are adjusted for inflation each year.
