Lockout/Tagout's Evidence Gap: What 4,771 OSHA Violations Reveal

OSHA data shows missing paperwork, not missing locks, drives over 70% of lockout/tagout violations.

An analysis of 4,771 OSHA lockout/tagout violations from fiscal year 2025 shows employers were cited far less for missing hardware than for missing proof that the right procedure was current, followed, verified, and inspected.

Ask most people to picture a lockout/tagout problem and they will picture hardware: a padlock not applied correctly, a tag missing from a valve. OSHA's enforcement data tells a different story. In fiscal year 2025, safety inspectors cited employers for 4,771 lockout/tagout violations under 29 CFR 1910.147, carrying roughly $21.9 million in penalties [1, 2].

Across the full year of violations, almost none were about a missing lock. Nearly all were about missing proof: proof that the right procedure existed, was up to date, was followed by trained workers, and was reviewed on schedule. That gap, between having a program and being able to prove it was followed, is where lockout/tagout compliance is won or lost.

Three Paperwork Requirements Caused 71.5% of Violations

The 4,771 violations came from 2,636 inspections of 2,563 employers. Each violation is one specific requirement an inspector found unmet, and inspections rarely find just one problem: a site with a missing procedure usually has missing training records and a skipped inspection as well. The data covers both federal OSHA and the 27 states that run their own OSHA-approved programs [2]. (OSHA's well-known Top 10 list, which puts lockout/tagout at number four, counts federal inspections only. Adding the state programs roughly doubles the total [3].)

Most of the violations landed in just three areas. Energy-control procedures accounted for 1,491 violations, training for 1,000, and periodic inspection for 920. Together, those three areas made up 71.5% of all lockout/tagout violations for the year [2]. The single most cited requirement was 1910.147(c)(4)(i), which requires employers to develop, document, and use energy-control procedures. It was cited 1,066 times. Second, at 725, was the requirement to inspect each procedure at least once a year. Third, at 525, was the requirement to have an energy-control program at all [2].

Look at what is missing from that list: locks, tags, and isolation devices barely appear. The violations were about the paperwork around energy isolation: the written procedure, the proof that people were trained, and the proof that the procedure was reviewed.

This is not a story about reckless employers, either. Of the 4,771 violations, 3,658 were classified as serious, meaning OSHA judged the condition could cause death or serious injury. Only 18 were willful [2]. Most of these are ordinary workplaces with gaps they probably did not know they had.

The Most Common Gap: Proof The Procedure Was Followed

So far, the numbers show which parts of the standard were cited. They do not show what actually happened on the floor. That story sits in the written description an inspector attaches to each violation. The full 2025 citation analysis behind this article read those descriptions, which are reliably available for 2,095 of the violations (those from federal OSHA and the Illinois state plan), and sorted each one by the specific proof the inspector could not find [2]. The pattern is clear, and it matches the wider data.

Two kinds of proof were missing far more than any other. In 41% of those violations, the employer could not produce a current, machine-specific written procedure. Sometimes none existed. Sometimes a generic template stood in for one, or the procedure no longer matched the equipment after it had been modified. In another 22%, a procedure existed but there was no evidence it was actually used at the machine: energy sources were not fully isolated, steps were skipped, or no one verified zero energy before starting work.

Together, those two gaps made up 62.9% of the 2,095 violations [2]. Missing training records and undocumented inspections made up most of the rest.

The injury data drives the point home. Only 58 of the 2,095 violations, or 2.8%, describe an actual injury. But those injuries were concentrated in the same two gaps: 22 involved a procedure that was not followed, and 19 involved a procedure that was missing or wrong [2]. Put simply, the gap between what the procedure says and what actually happens at the machine is the most common problem in the data, the most dangerous one, and the one employers found hardest to prove they had under control.

Manufacturing Received The Most Violations

General manufacturing led with 1,369 violations, followed by fabricated metal and machinery at 917, food and beverage at 556, and plastics and rubber at 398 [2]. These are not careless industries. They are simply the workplaces where paperwork goes out of date the fastest. Equipment carries several energy sources at once: electrical, pneumatic, hydraulic, and stored mechanical energy. Machines get modified faster than the binders that describe them.

Workers de-energize equipment many times a day, often under time pressure, across shifts, including sanitation and clearing crews the day team never sees. A procedure that was accurate and well documented in January can easily be neither by June.

Four Steps to Avoid These Violations

The fix does not require new equipment. It requires treating the paperwork as part of the safety system itself. The violations point to four steps. First, keep every procedure machine-specific and up to date, and review it whenever the equipment changes, not just once a year; an outdated or generic procedure was the single largest gap in the data. Second, keep training records that link each authorized worker to the equipment they service, not just proof that a course was delivered.

Third, record what happens in the field: who applied the procedure, which isolation points were locked out, and that zero energy was verified before work began. Fourth, inspect each procedure at least once a year and document it. To a compliance officer, an undocumented inspection is no inspection at all.

The Real Question: Can You Prove It?

The 2025 data changes the question employers should be asking. Most programs can answer "do you have a lockout/tagout procedure?" The harder question is the one the violations keep asking: can you prove the right procedure was current for this machine, applied by a trained worker, verified at zero energy before work began, and inspected within the last year? For roughly two thirds of the violations with written descriptions, the answer at inspection time was no.

That is the evidence gap, and closing it takes discipline, not money. A strong lockout/tagout program is not the one with the most complete-looking binder. It is the one that can prove control at the machine on the day someone asks. In 2025, that was the day the citation was written.
