Top OSHA 1910.147 Citations of 2025: What to Fix Before Audit Day

Published May 4, 2026 by LOTO Compliance

OSHA's lockout/tagout standard sits in the agency's Top 10 Most Frequently Cited Standards every year. It has done so for more than a decade. The interesting question is not whether 1910.147 will get cited at your next inspection. The interesting question is which sub-paragraph will get cited and why. We pull the federal enforcement summaries every quarter and compare them with what we see across roughly 60 audits a year in automotive supply, food and beverage, plastics, packaging, and metals plants. The pattern barely shifts. Five sub-paragraphs do almost all the damage.

This post walks each one in plain language, with the specific gaps that drove the citation in the field and the fix that closes it. If you want a third-party review that mirrors what OSHA looks for, our annual LOTO audit produces the documentation an inspector expects, and our gap analysis covers the sites that are not yet audit-ready.

How OSHA Counts LOTO Citations

Before the list, a note on how the numbers get reported. OSHA's Top 10 snapshot publishes total counts per standard. The deeper sub-paragraph view comes from the SIC and NAICS data feeds and from the Establishment Search tool. We use both. A plant that has one weak procedure on one machine can collect multiple citations because OSHA issues counts per affected employee or per affected machine, depending on the violation. A single audit can produce six-figure penalty exposure when the same gap repeats across the floor.

Citation classifications matter too. A serious citation tops out around $16,550 in FY2025 under the inflation-adjusted schedule. Willful and repeat citations push toward $165,000 each. Multi-employer citations land on integrators and contractors when they ran the work and the host plant did not control the energy. None of this is theoretical. We see it on the floor.

1. 1910.147(c)(4)(i): No Specific Procedure

This sub-paragraph requires the employer to develop, document, and use specific energy control procedures. Specific is the word that drives the citation. A binder full of generic boilerplate covering "all hydraulic equipment" or "the press department" does not meet the standard. OSHA expects one procedure per energy control situation, named to the equipment, with the actual isolation points and the actual sequence.

Common gaps that drove this citation in 2025:

• One catch-all procedure used across a whole department, with no machine identification.
• A procedure for a machine that no longer exists after a retrofit, with the new machine running uncovered.
• A procedure that lists energy sources but skips the isolation point for each source.
• Procedures stored on a shared drive that floor employees cannot reach during a shutdown.

The fix is structural. Build a master equipment list. Map each entry to a procedure. Publish procedures at the machine where they will be used, in addition to the binder and the digital copy. Make the procedure ID match the asset tag. When engineering changes a machine, the work is not done until the procedure is updated and re-issued.

2. 1910.147(c)(7)(i): Training Gaps

The training paragraph is the second most common citation. It carries three buckets: authorized employees, affected employees, and other employees who work in the area but do not service equipment. Each bucket has a different training scope, and each one has to be documented.

Where plants get caught:

• Authorized employees trained once at hire, never retrained, no records older than three years on file.
• Affected employees who work around isolated machines but cannot describe what a lockout means or why they should not touch a tagged switch.
• Contractors and integrators on site under the host's program with no documentation of host-coordinator training under 1910.147(f)(2).
• Retraining required by 1910.147(c)(7)(iii) after a procedure change or near-miss never happened.

The fix is a training matrix that lists every name, every role, every required module, and the next due date. Tie it to the HR onboarding flow so new hires cannot start service work before authorized-employee training is recorded.

3. 1910.147(c)(6)(i): Periodic Inspection Failures

The annual periodic inspection sits at number three. We covered the mechanics of running it in our 2026 audit checklist. The citation pattern in 2025 was almost entirely about missing or stale certifications, not about poor inspections. Plants that ran a real inspection but did not document it correctly still get cited.

The fix is calendar discipline. Assign a single owner. Use software, a spreadsheet, or a wall calendar. Doesn't matter, as long as someone watches the dates. Certify in writing the machine, the procedure, the date, the employees observed, and the inspector. File the certification where it can be retrieved within five minutes during an OSHA visit.

4. 1910.147(c)(4)(ii): Procedure Content Gaps

This sub-paragraph defines what each written procedure must contain. Six elements are required: a specific statement of the intended use, the steps for shutting down and isolating, the steps for placing locks and tags, the requirements for testing and verifying isolation, the steps for releasing from LOTO, and the methods for transferring locks during shift change. Skipping any element draws a citation.

What we see most often in the field:

• Procedures that describe the isolation but not the verification step. The "try the start button" check disappears in roughly one in three plant-written procedures.
• No documented method for transferring locks during shift change, even when the machine runs across two shifts.
• Procedures that reference a missing equipment list, leaving the inspector to guess which machine is covered.

The fix is a template. Build one master template that contains all six required elements, then fill it out for each machine. We use a one-page format that shows isolation points on a small line drawing, lists the lock and tag specs, and spells out the verification method. The format is replicable, and it scans cleanly during a walk-through.

5. 1910.147(d)(4)(i): Verification Skipped

The "try out" step at 1910.147(d)(4)(i) requires the authorized employee to verify isolation before service begins. Press the start button. Open the valve. Move the controls. Verify zero energy state. The citation pattern here is almost always a video or a witnessed observation showing that the verification step was skipped or rushed. It rolls into a serious citation because skipping it puts the worker directly in the path of stored energy.

The cause on the floor is rarely lack of training. It is production pressure. The line is down, the operator is leaning on maintenance, and the verification step takes ninety seconds that no one wants to spend. A retraining session does not fix this. A standing rule that the verification step is never optional, paired with supervisor accountability, is the only structural fix we have seen hold.

FY2025 Citation Mix at a Glance

Numbers are approximate, drawn from federal OSHA enforcement summaries. State-plan states (Michigan, Indiana, Illinois state-plan partial coverage, and others) follow the same federal standard with similar citation patterns. Robotics-heavy NAICS codes (336, 333, 326) skew slightly toward (c)(4)(i) because retrofits leave procedures behind.

The 30-Day Path to Audit-Ready

If your plant has not run a real LOTO review in the last twelve months, here is the fastest sequence we have seen work. It is the same playbook we use when a client calls because OSHA is already on site or because a corporate audit is six weeks out.

1. Pull the master equipment list and the procedure binder. Compare them. Every machine that runs energized service must have a specific written procedure. Flag the misses.
2. For each existing procedure, walk it at the machine with an authorized employee. Watch them isolate, lock, tag, and verify. Note any step that does not match the document.
3. Pull the last three years of periodic inspection certifications. Anything older than 12 months is a citation in waiting. Schedule a fresh inspection.
4. Pull the training records. Confirm authorized, affected, and other-employee training is current. Schedule retraining where it has lapsed.
5. Issue a corrective action log with owners and dates. Close the gaps in priority order, starting with anything that affects high-energy or high-frequency machines.

A four-person plant safety team can move through this in three weeks for a midsize manufacturer. A single EHS manager covering two facilities will need outside help. That is when the call comes in to us.

Frequently Asked Questions

What is the most-cited paragraph of OSHA 1910.147 in 2025?

29 CFR 1910.147(c)(4)(i), the requirement to develop and use specific written energy control procedures, has been the single most-cited LOTO sub-paragraph for several enforcement years running. Plants get cited when generic boilerplate procedures sit in the binder instead of machine-specific isolation steps. OSHA expects one written procedure per energy control situation, named to the equipment.

How much is a typical OSHA LOTO citation in 2025?

Serious citations under 1910.147 currently carry a maximum penalty around $16,550 per violation under the FY2025 inflation-adjusted schedule. Willful or repeat citations climb to roughly $165,000. Multi-instance citations are common because OSHA issues one count per affected machine or per affected employee, so a single audit can produce six-figure exposure quickly.

Does OSHA still cite tagout-only programs?

Yes, and tagout-only systems draw extra scrutiny. The standard at 1910.147(c)(2)(iii) requires the employer to demonstrate that the tagout program provides protection equivalent to lockout. In practice this means extra training, a second isolation step, and documentation showing why a lock could not be applied. Most facilities cannot meet that bar, which is why lockout has become the default.

What single fix prevents the most LOTO citations?

A current, machine-specific written procedure tied to a periodic inspection calendar prevents most citations. Roughly half of LOTO findings root back to either a missing procedure for a particular machine or a procedure that no longer matches the equipment after a retrofit. A management-of-change trigger that flags LOTO updates whenever engineering changes a machine closes that gap.

How does OSHA find LOTO problems during an inspection?

Compliance officers walk the floor, pick a machine, and ask to see the procedure for that specific asset. They watch an authorized employee perform an isolation, compare what happens to what the document says, and pull training and inspection certifications. Discrepancies between the binder and the field drive most citations. The paper trail rarely matches reality without an annual outside review.

Are robot cells inspected differently from other machines under 1910.147?

OSHA 1910.147 applies to robot cells the same way it applies to any other machine, but inspectors look harder at residual energy in servo drives, multi-source isolation including pneumatic and vacuum, and access control during teach modes. ANSI R15.06 and ISO 10218 fill in the robotic specifics. A cell with a single-point lockout and no documented servo discharge time is a common citation pattern.
