OSHA's electrical safety standards require you to deenergize equipment before work whenever feasible, restrict work on energized parts to qualified persons, and prove all of it with documented training, permits, and test-equipment records.
What Does OSHA Actually Require for Electrical Safety on a Job Site?
OSHA's electrical safety-related work practice rules — 29 CFR 1910.331 through 1910.335, with the construction-specific guarding rule at 29 CFR 1926.403 — obligate you to do four things as an employer: keep unqualified people away from energized parts, deenergize equipment before work unless deenergizing creates a greater hazard, restrict any energized work to qualified persons following a defined verification sequence, and train workers to a documented, risk-based standard. None of this is optional paperwork. It's what an OSHA compliance officer will ask to see first, and it's what your qualified electricians and electrical-adjacent trades are supposed to be following on every panel, MCC, or piece of switchgear they touch.
The rest of this post breaks down each obligation the way an inspector will look for it, and where a written program or a course certificate isn't enough — where you need records, not just policy.
Who Counts as a "Qualified Person" Under OSHA — and Why It Matters for Compliance
A qualified person, as defined at 29 CFR 1910.399, is one who has received training in and has demonstrated skills and knowledge in the construction and operation of electric equipment and installations and the hazards involved. This is not a job title. It's not "the electrician we hired." It's a status tied to specific equipment and specific hazards, and it's the gatekeeper for who is legally allowed to work on anything that hasn't been deenergized.
Under 29 CFR 1910.333(c)(2), only qualified persons may work on electric circuit parts or equipment that has not been deenergized under your lockout/tagging procedure — at any voltage. There is no 50-volt floor on this requirement. The 50-volt figure that shows up elsewhere in the standard (in the deenergization exemption at 1910.333(a)(1), and in the guarding requirement at 1926.403(i)(2)(i)) does not set the bar for who's "qualified." Hazards can exist below 50 volts, and the qualified-person rule applies regardless.
For an inspection, this means you need to be able to show, person by person, who is qualified for which equipment, and on what basis — training records, demonstrated skill, and knowledge of the hazards. "He's been doing this for years" is not documentation.
What Has to Happen Before Anyone Touches Energized Equipment?
Deenergization is the default. Energized work is the exception, and it has to be justified. 29 CFR 1910.333 requires you to deenergize equipment before employees work on or near it, unless deenergizing itself creates a greater hazard.
When equipment can't be deenergized, that's where an energized electrical work permit and PPE selection come in — this is where your program has to connect OSHA's performance-based requirement to a documented process, because OSHA doesn't hand you the PPE tables itself.
What's the Deenergization Sequence Contractors Have to Follow?
Creating an electrically safe work condition under 29 CFR 1910.333(b)(2) is a specific sequence, not a general lockout/tagout under 1910.147:
1. Identify all sources of electrical supply to the equipment. 2. Open the disconnecting device for each source after the load is interrupted. 3. Release stored electric energy — discharge capacitors, short-circuit and ground high-capacitance elements, and block or relieve stored non-electrical energy. 4. Apply lockout or tagout devices per your established procedure (required at 1910.333(b)(2)(iii)(A)). 5. Have a qualified person operate the equipment's controls, or otherwise verify the equipment cannot be restarted. 6. Test circuit elements and parts employees will be exposed to, to verify deenergization, using a test instrument that meets 29 CFR 1910.334(c).
Opening a breaker or switch is not, by itself, a safe work condition. Disconnects fail, get mislabeled, or don't control every source feeding the equipment. Testing at the actual point of work — not just at the disconnect — is what makes the condition verified rather than assumed.
What Are the Test-Equipment Requirements Contractors Get Cited For Missing?
29 CFR 1910.334(c) requires that test instruments, leads, cables, probes, and connectors be visually inspected for damage before use and be rated for the circuit and equipment being tested. There's no periodic-testing mandate in the rule itself — the requirement is pre-use inspection and correct rating, every time.
Above 600 volts nominal, 1910.333(b)(2)(iv)(B) adds a functional check of the test instrument immediately before and immediately after the absence-of-voltage test. If the instrument fails the post-use check, the worker has to treat the circuit as though it was never verified deenergized and start the sequence over. Non-contact voltage detectors and proximity testers cannot serve as the sole or primary verification method for a qualified person establishing an electrically safe work condition.
When Does OSHA Require an Energized Electrical Work Permit?
OSHA's baseline rule is that energized work is only permitted when deenergizing creates a greater hazard (for example, cutting power to life-support or emergency ventilation) or the task is inherently impossible to do deenergized, such as diagnostics, testing, or troubleshooting. The employer is responsible for a formal risk assessment to determine the incident energy exposure and required PPE for that specific task before work starts.
For documentation purposes, this means your file needs the justification for the energized work, not just a signature. "We didn't want to shut down the line" is not a valid basis.
What PPE Is a Contractor Obligated to Provide for Electrical Work?
29 CFR 1910.335(a)(1)(i) requires employees working where electrical hazards are present to use protective equipment appropriate for the parts of the body exposed and the work being performed. That's a performance standard — OSHA doesn't hand you a PPE category table in the regulatory text itself. You have to be able to show how you translated "appropriate" into an actual selection process: incident energy analysis or equivalent, and PPE matched to that analysis for each task.
Undergarments matter here too. Synthetic or polyester-blend wicking shirts can melt to the skin during an arc flash even when the outer arc-rated layer holds — non-melting, natural-fiber undergarments are part of what "appropriate protective equipment" has to mean in practice.
What Approach Distances and Guarding Does OSHA Actually Set?
Separate from PPE selection, OSHA sets hard clearance numbers directly in the regulatory text at 29 CFR 1910.333(c)(3):
| Requirement | Distance |
|---|---|
| Unqualified persons (and conductive objects they hold) near unguarded energized overhead lines at 50kV or below | 10 ft. (305 cm), plus 4 in. for every 10kV over 50kV |
| Qualified persons near exposed energized parts, over 300V but not over 750V (Table S-5) | 1 ft. 0 in. (30.5 cm) |
| Vehicles or mechanical equipment capable of elevation, near energized overhead lines | 10 ft. (305 cm) |
Qualified persons have to be trained in these distances under 1910.332(b)(3)(iii) — it's a specific, citable training element, not a general awareness point.
Separately, 29 CFR 1926.403(i)(2)(i) requires that live parts of electric equipment operating at 50 volts or more be guarded against accidental contact — by cabinets, enclosures, locked rooms, partitions or screens, elevated platforms, or 8-foot elevation — arranged to exclude unqualified persons.
What Training Records Does OSHA Expect You to Maintain?
29 CFR 1910.332(c) requires that training be classroom or on-the-job type, with the degree of training determined by the risk to the employee. The regulation itself does not impose a training-documentation or record-retention duty — the one written-record requirement in this subpart is the written lockout/tagging procedure at 1910.333(b)(2)(i). That said, keeping training records — who was trained, on what, and when — is standard industry practice and the only practical way to demonstrate compliance during an inspection, because "the degree of training determined by the risk" is something you have to be able to justify after the fact.
This is also where the qualified-person status connects back to ongoing compliance: qualified-person status is not permanent. It requires periodic re-evaluation as equipment, tasks, and hazards change. If your safety manager can't produce a record showing when someone was last trained on a given piece of equipment, that gap is exactly what an inspection will surface.
How Do You Prove Electrical Safety Compliance During an OSHA Inspection?
An inspector isn't going to take your word that people are qualified, that permits get justified, or that test equipment gets checked. What holds up is documentation tied to specific people, specific equipment, and specific dates:
- Qualified-person determinations, per employee, per equipment type
- The written lockout/tagging procedure required at 1910.333(b)(2)(i)
- Energized electrical work permits with documented justification for each instance
- PPE selection records tied to incident energy or equipment labeling
- Training records showing topic, date, and who attended
The gap most contractors get caught in isn't the field work — it's that the paperwork lives in three different binders, on someone's laptop, and in a supervisor's head, and none of it lines up when an OSHA officer asks for it on the spot.

FAQ
Does OSHA set a voltage threshold for who counts as a qualified person?
No. The qualified-person requirement at 29 CFR 1910.333(c)(2) applies at any voltage to work on equipment that hasn't been deenergized. The 50-volt figure that appears elsewhere in the standard is a deenergization exemption (1910.333(a)(1)) and a guarding trigger (1926.403(i)(2)(i)), not a qualified-person threshold.
Is opening a breaker enough to make equipment safe to work on?
No. OSHA's electrically safe work condition sequence at 29 CFR 1910.333(b)(2) requires identifying all sources, opening disconnects, releasing stored energy, applying lockout/tagout, verifying the equipment can't restart, and then testing at the point of work with an instrument meeting 29 CFR 1910.334(c). Disconnects can fail or be mislabeled, so testing is mandatory, not optional.
When is a contractor allowed to have employees work on energized equipment?
Only when deenergizing would create a greater hazard (such as loss of power to life-support or emergency ventilation) or the task is inherently impossible to perform deenergized, such as diagnostics, testing, or troubleshooting. That justification has to be documented, typically through an energized electrical work permit, along with a risk assessment for required PPE.
What training records does OSHA require an employer to keep for electrical safety?
The regulatory text at 29 CFR 1910.332(c) requires training appropriate to the employee's risk but doesn't itself mandate a documentation or retention system. The one written-record requirement in this subpart is the written lockout/tagging procedure at 1910.333(b)(2)(i). In practice, maintaining training records is how a safety manager proves compliance during an inspection.
