An OSHA lockout tagout violation costs up to $16,550 per serious citation and up to $165,514 for willful or repeat violations under the 2026 penalty schedule. Fixing one means correcting the cited gap by the abatement deadline, then closing the program holes behind it: machine-specific procedures, training, and annual inspections.
1910.147 drew 2,177 citations in FY2025, good for #4 on OSHA's Top 10. If your facility has been cited, or you suspect your program has gaps, this guide walks the penalty math, the sub-clauses OSHA cites most, and the path out of compliance exposure.
Understanding the Standard
29 CFR 1910.147 is OSHA's standard for The Control of Hazardous Energy. Commonly called the lockout tagout (LOTO) standard. It requires employers to establish energy control procedures, train employees, and run periodic inspections that protect workers servicing or maintaining machines.
When a compliance officer inspects your facility and finds your energy control program falls short, they issue a citation. Citations are classified by severity, and each classification carries a different maximum penalty. That classification drives both the financial exposure and the urgency of your response.
1910.147 has held a spot in OSHA's Top 10 year after year. In FY2025 it landed at #4 with 2,177 citations. The majority of those are gaps that were identifiable and correctable before the inspector ever showed up.
FY2025 snapshot: 2,177 total 1910.147 citations across US manufacturing. Serious violations carry a maximum penalty of $16,550 each. Source: OSHA Top 10 cited standards and the DOL penalty schedule.
Key point: Penalties apply per violation, per machine. A plant with 50 machines and no written LOTO procedures can face 50 separate serious citations in a single inspection. The math compounds fast.
Current Penalty Schedule
OSHA normally adjusts penalty maximums each January for inflation, but no adjustment was made for 2026 because the late-2025 federal shutdown left the Bureau of Labor Statistics without the October CPI data the calculation requires. OSHA's May 21, 2026 enforcement memo confirms the 2025 maximums below remain in effect through 2026. Verify the latest amounts at osha.gov/penalties.
Up to $16,550
per violation
Job-safety related but unlikely to cause death or serious physical harm. Still carries real financial weight. Still signals program gaps that need attention.
Up to $16,550
per violation
A hazard the employer knew or should have known about that could cause death or serious physical harm. Most LOTO citations land here. Each machine out of compliance can be cited separately.
Up to $165,514
per violation (minimum $11,823)
The employer intentionally committed the violation or acted with plain indifference to employee safety. Willful carries the harshest penalties and can trigger criminal referrals if a worker is killed.
Up to $165,514
per violation
The employer has been cited for a substantially similar violation within the past five years. Cited for missing machine-specific procedures last time and OSHA finds the same issue again? Expect dramatically higher penalties.
Up to $16,550 per day
beyond the abatement deadline (generally limited to 30 days maximum)
Receive a citation, miss the deadline, and penalties accumulate daily. OSHA's 2026 penalty memo caps accrual at 30 days in most cases, but 30 days at $16,550 still adds nearly $500,000 on top of the original fine. This is where facilities face the largest unexpected financial exposure.
Revisions to Chapter 6 of OSHA's Field Operations Manual took effect July 14, 2025 and expanded the discounts smaller employers can receive. The maximum size-based reduction now covers employers with 1 to 25 employees (previously 1 to 10), and employers with 11 to 25 employees receive a 70 percent reduction instead of 60. For serious willful violations, the 80 percent reduction now extends to employers with 20 or fewer employees. The good-history reduction doubled from 10 percent to 20 percent. These factors are applied at OSHA's discretion during penalty calculation, and an informal conference is where you make the case for them. Our annual LOTO audit service builds the documented compliance history that supports a good-faith argument.
Common Citation Triggers
No written energy control procedures, or procedures that are not machine-specific (c)(4). OSHA requires a documented procedure for each machine where employees service or maintain equipment. A single generic procedure covering the whole facility does not meet the standard. Every machine with distinct energy sources needs its own procedure identifying type and magnitude of energy, the location of isolating devices, and the steps to shut down, isolate, block, and verify.
Failure to conduct the required annual periodic inspection (c)(6). Employers must perform an annual review of each energy control procedure to confirm it is still adequate and that employees understand it. The inspection must be performed by an authorized employee other than the one using the procedure. Many facilities skip it, run it inconsistently, or fail to document it.
Inadequate or missing employee training (c)(7). Every authorized, affected, and other employee needs training appropriate to their role. Authorized employees apply and remove energy controls. Affected employees understand the purpose and limits of the program. Retraining is required when procedures change, job assignments change, or inspections reveal knowledge gaps.
Robotics and automation gaps. New equipment, robotic cells, and automated lines bring energy sources and access patterns that legacy LOTO programs were never designed to address. Interlock gated entry, safeguarded access zones, and multi-energy robotic cells need updated procedures and specialized placards that spell out the isolation steps for each access point.
No verification of zero energy state (d)(6). The standard requires employees to verify that isolation and de-energization are complete before starting work. The "try" step. Skipping it, or leaving it out of the written procedure, is one of the most frequently cited operator failures.
Multiple citations per inspection: A common enforcement pattern: OSHA issues multiple citations in a single LOTO inspection, because a program failure usually breaks multiple sub-requirements simultaneously. FY2025 sub-clause counts: 730 citations under (c)(4), 491 under (c)(7), and 362 under (c)(6).
After the Inspection
Once OSHA issues a citation, the clock starts. Here is how the process unfolds and what your options are at each stage.
Each citation includes a required abatement date. The deadline by which you must correct the violation. Non-negotiable unless you formally contest. Failure-to-abate penalties begin accruing the day after that deadline passes.
You have 15 business days from receipt of the citation to contest. File a notice of contest within that window or the citation becomes a final order. Do not let this deadline pass.
Before the contest deadline, you can request an informal conference with the OSHA Area Director. Often the most practical first move. You may negotiate penalty reductions, extended abatement dates, or clarification on abatement expectations. Does not waive your right to formally contest.
If you contest, the case goes to the Occupational Safety and Health Review Commission for a hearing before an administrative law judge. Typically reserved for cases where the employer believes the citation is fundamentally incorrect or the penalties are disproportionate.
Do not ignore a citation or let the 15-day window pass. Once the deadline expires, the citation is final, penalties are owed in full, and you lose all room to negotiate or contest. Whether you plan to abate, negotiate, or contest, act within the first week.
Coming Into Compliance
Already cited, or trying to get ahead of a potential inspection? The path to a compliant LOTO program follows the same core steps.
Step 1: Run a full gap analysis. Walk the floor. Assess every machine and piece of equipment covered by the standard. Identify where written procedures are missing, where existing procedures are generic or outdated, and where energy sources are undocumented. The foundation everything else builds on.
Step 2: Develop or update machine-specific procedures (c)(4). Each machine needs a procedure that identifies all energy types and magnitudes, specifies isolation points and devices, and outlines the exact sequence to achieve and verify a zero-energy state.
Step 3: Install or replace LOTO placards and signage. Durable, machine-mounted custom LOTO placards that match your written procedures make compliance visible and enforceable on the floor. Paper or laminated placards degrade and become unreadable. Industrial-grade aluminum placards rated for long-term use are the standard that passes inspection.
Step 4: Train all employees by role (c)(7). Authorized employees learn to apply and remove locks and tags. Affected employees learn the purpose and restrictions of the program. Other employees learn to recognize and respect lockout situations. Document every training session with dates, topics, and attendee signatures.
Step 5: Establish the annual periodic inspection process (c)(6). Set a schedule, assign qualified reviewers, and build a documentation system that captures each review. LockStep software centralizes this process and creates an auditable trail that satisfies the written certification requirement under (c)(6)(ii).
Step 6: Address robotics and automation specifically. If your facility has robotic cells, automated lines, or interlock gated access, make sure your program covers these with dedicated procedures and clear access control placards. One of the fastest-growing areas of LOTO enforcement.
Facilities that partner with a compliance specialist finish faster because they skip the common pitfalls: generic procedures, wrong placard specs, missed equipment. Our team handles every step from gap analysis through installation and training.

Common Questions
A serious 1910.147 violation currently caps at $16,550 per citation. Willful or repeat violations go up to $165,514 each. Failure-to-abate runs up to $16,550 per day past the abatement date. No inflation adjustment was made for 2026, so these maximums remain in effect.
Three sub-clauses drive most 1910.147 citations: (c)(4) missing or non-machine-specific written procedures, (c)(7) inadequate or missing training and retraining, and (c)(6) the annual inspection that was skipped or never documented. The verification step in (d)(6) is among the most frequently skipped operator steps.
You have 15 business days to contest. Every citation carries an abatement deadline. Request an informal conference with the OSHA Area Director before that window closes to negotiate penalties or abatement dates. Miss the 15-day window and the citation becomes a final order with no further contest rights.
Yes. Under the Field Operations Manual revisions effective July 14, 2025, employers with 1 to 25 employees qualify for the maximum size reduction, and employers with 11 to 25 employees now get 70 percent instead of 60. The good-history reduction also doubled from 10 percent to 20 percent.
Failure-to-abate penalties run up to $16,550 per day past the abatement deadline, and OSHA's 2026 penalty memo notes they are generally limited to 30 days maximum. That still means exposure approaching $500,000 on a single uncorrected violation, so abatement deadlines deserve immediate attention.
