A Lock Only Protects the Person Who Hung It
LOTO standards are some of the most cited rules in American industry. Lockout/tagout ranked #4 on OSHA’s Top 10 Most Frequently Cited Standards for FY2025, and it’s been on that list for years.
Having locks isn’t usually the problem, and neither is having a written program. The citations and the injuries come from the gaps between the paperwork and the job: a procedure that doesn’t match the machine, a crew that doesn’t verify zero energy, a shift change where nobody owns the isolation.
If you’re a safety manager, operations manager, or shop owner trying to figure out which LOTO standard actually governs your work — OSHA 1910.147, the construction rules in 1926, ANSI/ASSP Z244.1, or ISO 45001 — this guide lays out what each of these lockout/tagout standards requires and where programs break down.
From the Floor: I was managing a coatings project inside a food processing plant when the whole plant shut down mid-morning: a welder had cut into a nitrogen line that was back under pressure. The last welder on second shift had pulled his lock, the line was put back in service overnight, and first shift walked in assuming it was still isolated — nobody hung a new lock or verified zero energy before the torch came out. That welder went to the hospital with critical injuries. When the plant’s maintenance manager, my contact for the project, walked me through what happened, one thing stood out to me: the problem wasn’t missing equipment. It was an inexperienced crew treating someone else’s lockout as their own.

Which LOTO Standards Actually Apply to Your Work?
The answer depends primarily on what kind of work is being done, not simply on whether the employer calls itself a manufacturer, contractor, or fabricator.
A fabrication shop servicing its own press brake is under general industry rules. The same shop’s field crew doing a tie-in at a refinery turnaround may fall under construction rules. A contractor maintaining equipment inside a host plant may be working under the host’s program and its own at the same time.
| Standard | What It Covers | Legal Status |
|---|---|---|
| OSHA 29 CFR 1910.147 | Servicing and maintenance of machines and equipment in general industry | Mandatory (federal law) |
| OSHA 1910.333 (Subpart S) | Electrical work on or near exposed conductors and circuit parts | Mandatory; a 1910.147 program can cover it if it meets two added electrical provisions |
| OSHA 1926.417 | Lockout and tagging of electrical circuits in construction | Mandatory for construction work |
| OSHA 1926.702(j) | Lockout/tagout for concrete and masonry equipment | Mandatory for that equipment in construction |
| ANSI/ASSP Z244.1-2024 | Lockout, tagout, and alternative methods for installing, setup, troubleshooting, servicing, and other covered activities; construction and demolition covered by A10.44 are excluded | Voluntary consensus standard |
| ANSI/ASSP A10.44-2020 | Control of energy sources for construction and demolition operations | Voluntary consensus standard |
| ISO 45001:2018 | Safety management system framework that energy control plugs into | Voluntary; certifiable |
⚠️ 1910.147 does not apply to construction work. The general industry standard specifically excludes employment covered by 29 CFR 1926. That catches contractors off guard — and the construction rule that does apply, 1926.417, is written around electrical circuits and allows tags where general industry would require a lock.
OSHA’s Control of Hazardous Energy overview lists the related standards for maritime, construction, and state-plan programs.

OSHA 1910.147: What the Standard Actually Requires
The general industry standard requires a three-part energy control program: written procedures, employee training, and periodic inspections. Every citation traces back to one of those three pieces or to how the procedure was applied on the floor.
Machine-Specific Energy Control Procedures — 1910.147(c)(4)
Procedures must be developed, documented, and used for the control of hazardous energy on each machine or piece of equipment. Each one must spell out the scope, steps for shutting down and isolating, steps for placing and removing locks, and how to verify that the energy is actually controlled.
Common finding in practice: a single corporate LOTO policy covering every machine in the building. A policy is not a procedure. The inspector wants to see the steps for the press in bay four, including the pneumatic dump valve and the counterweight — not a generic “turn off power, apply lock.”
There’s one narrow exception: a written procedure isn’t required when the equipment meets all eight conditions in 1910.147(c)(4)(i) — a single energy source, no stored energy, a single lockable isolation point, exclusive control by the authorized employee, and no accident history, among others. In my experience, few machines in a fabrication shop qualify.
Lockout vs. Tagout — 1910.147(c)(2) and (c)(3)
If an energy isolating device can accept a lock, 1910.147 generally requires lockout — unless the employer can demonstrate that tagout provides full employee protection equal to lockout. Tagout alone is also used where the device physically can’t accept a lock. Since January 2, 1990, new machines and equipment, along with machines undergoing replacement, major repair, renovation, or modification, must have energy isolating devices designed to accept a lockout device.
Training — 1910.147(c)(7)
The standard separates three groups of people:
- Authorized employees — the people who apply locks and perform the servicing. They need training in recognizing hazardous energy sources, the type and magnitude of energy, and the methods to isolate it.
- Affected employees — operators and others who work on or near the equipment. They need to know the purpose of the procedure and to never try to restart locked-out equipment.
- Other employees — anyone who might be in the area. They need to understand the prohibition against restarting.
Retraining is required when job assignments, equipment, processes, or procedures change — or when a periodic inspection shows someone doesn’t know the procedure.
Periodic Inspection — 1910.147(c)(6)
At least annually, an authorized employee other than the ones using the procedure must inspect each energy control procedure and certify the inspection in writing. A common finding in practice: the inspection is either skipped, done as a paperwork review with no observation, or documented without identifying the equipment, the date, and the employees included.
The Six-Step Application Sequence — 1910.147(d)
| Step | Requirement | Where It Fails on the Floor |
|---|---|---|
| 1. Preparation | Authorized employee knows the energy types, magnitude, and hazards | Worker unfamiliar with the machine skips the procedure |
| 2. Shutdown | Machine is shut down using the normal procedure | Emergency stop used as the “isolation” |
| 3. Isolation | All energy isolating devices operated | Secondary sources missed — pneumatics, gravity, backfeed |
| 4. Lock/tag application | Each authorized employee applies a lock or tag | One lock for a whole crew |
| 5. Stored energy | Residual energy relieved, disconnected, or restrained | Accumulators, springs, capacitors, and pressurized lines not bled |
| 6. Verification | Isolation and de-energization verified before work starts | “Try” step skipped because the lock is already on |
Step 6 is the one that would have stopped the injury in my story. A welder who verified zero pressure before cutting would have found a live line.
If you’re dealing with the guarding side of the same equipment, Machine Guarding Standards covers where guarding stops and energy control starts.
The Three Situations Where LOTO Programs Break
A program that works fine on a routine job with one mechanic and one machine can break down when the job gets bigger, longer, or involves more than one employer. OSHA addresses all three situations in 1910.147(f) — and these paragraphs are the ones crews are least likely to have read.
Shift and Personnel Changes — 1910.147(f)(4)
The standard requires specific procedures during shift or personnel changes to keep lockout protection continuous, including an orderly transfer of lockout devices between off-going and oncoming employees.
The key word is orderly. The off-going worker doesn’t pull his lock and go home. The oncoming worker applies his lock first, then the off-going worker removes his. At no point is the equipment left without a lock from someone who is actually exposed.
That’s exactly what didn’t happen at the food plant. Second shift’s last lock came off, the line was put back in service, and first shift assumed a lockout that no longer existed.
Group Lockout — 1910.147(f)(3)
When a crew services equipment together, the standard requires a level of protection equivalent to each worker applying a personal lock. The common tools are a group lockbox (the primary authorized employee locks the isolation points and puts the keys in a box; every crew member adds a personal lock to the box) or a multi-lock hasp on each isolation point.
Either way, the principle is the same: every exposed worker hangs a personal lock, and nobody removes a lock that isn’t theirs. One lock for a whole crew is not group lockout.
Outside Contractors — 1910.147(f)(2)
When outside servicing personnel work in your facility, the host employer and the contractor must inform each other of their energy control procedures, and the host must make sure its own employees understand and follow the contractor’s program.
If you are a contractor working inside a general-industry plant → get the host’s LOTO procedure for the specific equipment in writing before your crew touches it, and agree on who controls isolation at shift change.
If you are the host employer bringing in contractors → treat the pre-job LOTO briefing as a documented step, not a hallway conversation. That contractor coordination can also support the requirements of ISO 45001 clause 8.1.4, particularly where the host and contractor share responsibility for controlling operational risks.

The Exceptions Crews Misread
1910.147 has exceptions. They’re narrow, and each one has conditions that crews tend to drop.
| Exception | What It Actually Allows | The Condition People Skip |
|---|---|---|
| Minor servicing during normal production | Routine, repetitive tasks integral to production (e.g., minor tool changes) without full LOTO | Only if alternative measures provide effective protection — not just “it’s quick” |
| Cord-and-plug equipment | Unplugging instead of locking out | The plug must be under the exclusive control of the employee doing the work |
| Hot tap operations | Work on pressurized pipelines when shutdown is impractical | Continuity of service must be essential, shutdown impractical, documented procedures followed, and special equipment used |
The hot tap exception deserves attention in any shop that does pipe work. It is not a general permission to work on a live line. It applies only to transmission and distribution systems for substances such as gas, steam, water, or petroleum products, and only when continuity of service is essential, shutdown is impractical, and documented procedures and special equipment provide proven effective protection. A welder who cuts a line he believes is dead — and it isn’t — is not doing a hot tap. He’s doing unprotected work on live equipment.
LOTO in Construction and Field Work
OSHA’s construction requirements for lockout and tagging are narrower than the general industry framework. That doesn’t make field work safer.
29 CFR 1926.417 requires that controls deactivated during the work be tagged, and that de-energized equipment or circuits be rendered inoperative with tags at every point where they can be energized. It is written around electrical circuits. It doesn’t give a field crew a framework for hydraulic, pneumatic, gravity, thermal, or pressurized-process energy — the energy that shows up during tie-ins, commissioning, demolition, and turnaround work.
That’s why many experienced contractors choose to run a general-industry-level program for field crews anyway. Two consensus standards help fill the gap:
- ANSI/ASSP A10.44-2020 — Control of Energy Sources (Lockout/Tagout) for Construction and Demolition Operations. It’s written specifically for contractors. ANSI/ASSP A10.44-2020 — ANSI Webstore
- ANSI/ASSP Z244.1-2024 — its scope covers activities such as erecting, installing, constructing, repairing, testing, troubleshooting, servicing, and maintaining machines, equipment, and processes. However, construction and demolition operations covered by A10.44 are outside Z244.1’s scope.
For companies that run both shop and field crews, Z244.1 and A10.44 work best as complementary standards — Z244.1 for the shop and plant-maintenance side, A10.44 for construction and demolition work — rather than one universal LOTO standard.
If you’re building out a broader construction safety library, the ANSI/ASSP A10 Construction Package bundles the A10 series — scaffolding, fall protection, cranes, and more — at a package discount.
For how shop and field programs should differ, see Building a Safety Management System That Works in the Shop and the Field. Energy isolation also runs straight into hot work permits and confined space entry — the three almost always show up on the same job.
ANSI/ASSP Z244.1-2024: What It Adds Beyond OSHA
OSHA 1910.147 sets mandatory requirements for hazardous energy control in general industry. ANSI/ASSP Z244.1-2024 provides a broader consensus framework for controlling that energy, including lockout, tagout, and alternative methods — and it’s been updated far more recently than OSHA’s rule.
ASSP publishes an overview of the standard on its Z244.1 standards page.
The 2024 edition presents three distinct approaches to controlling hazardous energy: lockout, tagout, and alternative methods. It also added a new section on hazardous energy control methods and a structured methodology for when full isolation isn’t practical.
| Topic | OSHA 1910.147 | ANSI/ASSP Z244.1-2024 | Key Difference |
|---|---|---|---|
| Legal status | Federal regulation | Voluntary consensus standard | OSHA is enforceable; Z244.1 is best practice OSHA can reference |
| Scope | Servicing and maintenance, general industry | Installing, setting up, troubleshooting, servicing, maintaining, and other covered activities; construction and demolition covered by A10.44 are excluded | Z244.1 lists covered activities more broadly; construction and demolition go to A10.44 |
| Alternative methods | Narrow minor-servicing exception | Structured risk-assessment process for alternatives when lockout isn’t practical | Z244.1 provides a structured risk-assessment framework |
| Control-circuit devices | Push buttons and selector switches not accepted as isolation | Addressed through alternative methods with risk assessment | Relevant to modern automated equipment |
| Edition date | Original rule 1989; effective January 2, 1990 | 2024 | Z244.1 reflects current control technology |
⚠️ Z244.1 does not replace OSHA 1910.147. Where OSHA’s regulation applies, a company can’t use a Z244.1 risk assessment to disregard a mandatory OSHA requirement — falling short of 1910.147 can still earn a citation. Use it to build a stronger program, not to argue your way out of the federal rule.
The ANSI/ASSP Z244.1-2024 PDF lists at $144 on the ANSI Webstore — and code CC2026 takes 5% off through December 31, 2026. ANSI Webstore also serves international buyers and offers many standards in multiple languages, which matters for multinational plants standardizing one LOTO program across sites.
If your LOTO program covers automated equipment or machine cells, pairing Z244.1 with the machine safeguarding standard usually makes more sense than buying them separately: ANSI/ASSP Z244.1 / ANSI B11.19 — Hazardous Energy Safeguarding Package — ANSI Webstore. For broader coverage, the ANSI B11 machine safety collection and ANSI’s standards bundle packages save meaningfully compared to buying titles one at a time.

Where Lockout/Tagout Standards Are Heading in 2026
OSHA is working on modernizing 1910.147. According to the Department of Labor’s regulatory agenda, the agency plans to publish a proposed rule (RIN 1218-AD00) by November 2026.
The main driver is technology. The current rule doesn’t accept push buttons, selector switches, and other control-circuit devices as energy isolation — a position that conflicts with how modern computer-controlled safety systems are designed. The proposal is expected to address when control-circuit-type devices could be used.
Two practical points while the rulemaking plays out:
- The existing 1910.147 requirements remain in effect unless and until OSHA publishes a final rule that changes them. A proposed rule does not itself change the current standard.
- Regulatory agenda dates slip. Build your program to the current rule and to Z244.1-2024, and watch for the proposal and its comment period.
The Standards Navigator will cover the proposed rule when it publishes.
Where ISO 45001 Fits
ISO 45001:2018 doesn’t contain LOTO requirements. It gives you the management system that keeps a LOTO program from decaying.
| ISO 45001 Clause | How It Applies to Energy Control |
|---|---|
| 6.1.2 — Hazard identification | Hazardous energy sources identified per machine and per task |
| 7.2 — Competence | Authorized and affected employee training tracked and refreshed |
| 8.1.2 — Hierarchy of controls | Isolation and engineering controls ahead of tags and administrative measures |
| 8.1.4.2 — Contractors | Host/contractor energy control coordination planned and verified |
| 9.1 / 9.2 — Monitoring and internal audit | Periodic inspections feed audit evidence and trend data |
| 10.2 — Incident, nonconformity, corrective action | LOTO near-misses investigated to root cause |
The 1910.147 annual periodic inspection is already a built-in monitoring activity. In an ISO 45001 system, those inspection results become audit evidence — and a failed inspection becomes a nonconformance with a corrective action, not just a retraining note in a file.
If you are already running ISO 45001 → map your periodic inspection records to clause 9.1 and make sure contractor LOTO coordination shows up under 8.1.4.
If you are building your first safety management system → start with the ISO 45001 Certification Guide and the ISO 45001 documentation requirements.
For internal auditors who need to evaluate energy control against clause requirements, BSI Group’s ISO 45001 training courses and ISOQAR’s ISO 45001 training both cover lead and internal auditor paths.
“OSHA Is the Law — Why Spend Money on a Voluntary Standard?”
It’s a fair objection. You’re already required to follow 1910.147. Why buy Z244.1?
Three reasons that matter on the shop floor:
- OSHA’s core LOTO rule dates to 1990. It was written before modern automated cells, robotic lines, and safety-rated control systems. Z244.1-2024 gives you a documented method for those situations instead of improvising.
- It goes deeper on the tasks where crews get hurt. Z244.1 spells out covered activities such as installing, setup, troubleshooting, and unjamming in more detail than OSHA’s rule, and adds a structured method for alternatives. For construction and demolition crews, A10.44 is the companion standard.
- The math isn’t close. The Z244.1 PDF lists at $144. The 2026 federal maximum for a single serious OSHA violation is $16,550, and $165,514 for a willful or repeat violation. The Cost of Non-Compliance in Manufacturing breaks down what those penalties look like in practice.
None of that counts the cost of an injury. The food plant incident shut down an entire production facility and put a man in the hospital.

Frequently Asked Questions
What are the main OSHA LOTO standards?
The main standard is 29 CFR 1910.147, The Control of Hazardous Energy (Lockout/Tagout), which covers servicing and maintenance in general industry. Electrical work on exposed conductors falls under Subpart S (1910.333), and construction work falls under 1926 rules, primarily 1926.417 for electrical circuits.
Does OSHA 1910.147 apply to construction?
No. 1910.147 excludes employment covered by 29 CFR 1926. Construction LOTO is addressed mainly by 1926.417 for electrical circuits and 1926.702(j) for concrete and masonry equipment. Many contractors still adopt a 1910.147-level program because the construction rules don’t address non-electrical energy in depth.
Is ANSI/ASSP Z244.1 mandatory?
No. Like A10.44, Z244.1 is one of the voluntary consensus LOTO standards, not a regulation. It becomes a requirement when a customer contract, a host facility, or your own safety program adopts it. OSHA can reference consensus standards when evaluating whether a hazard was recognized and how it could have been controlled.
What is the current edition of ANSI Z244.1?
The current edition is ANSI/ASSP Z244.1-2024, The Control of Hazardous Energy — Lockout, Tagout, and Alternative Methods. It replaced the 2016 edition (reaffirmed in 2020).
How often does OSHA require LOTO periodic inspections?
At least annually for each energy control procedure. The inspection must be done by an authorized employee other than the ones using the procedure, and the employer must certify it in writing with the machine, date, employees included, and inspector identified.
How should locks be handled at shift change?
Under 1910.147(f)(4), the employer needs specific procedures for an orderly transfer of lockout protection. In practice, the oncoming employee applies a personal lock before the off-going employee removes theirs, so the equipment is never without a lock from someone who is exposed.
Can one lock protect a whole crew?
Not by itself. Group lockout under 1910.147(f)(3) must give each worker protection equivalent to a personal lock. A lockbox or multi-lock hasp, where every exposed worker adds a personal lock, is the standard approach.
Are OSHA’s lockout/tagout standards changing in 2026?
OSHA has a modernization rulemaking underway. The Department of Labor’s regulatory agenda lists a proposed rule targeted for November 2026, focused largely on control-circuit-type devices used in modern equipment. The existing 1910.147 requirements remain in effect unless and until a final rule changes them.

Lockout/tagout isn’t complicated. Hanging a lock takes seconds. What takes discipline is making sure the right person’s lock is on the right isolation point for the entire time someone is exposed — through shift changes, crew changes, and contractor handoffs. Build your program around those moments — that’s where lockout/tagout standards actually earn their keep — verify zero energy every time, and you’ll close the gaps that put people in the hospital. The Standards Navigator will keep tracking LOTO standards, OSHA’s rulemaking, and the consensus standards that shape real-world energy control.
The Lock Came Off. The Line Came Back. Nobody Checked.
Organizations that struggle with LOTO treat it as a hardware problem — buy locks, hang a board, write one policy. They find out what’s missing when a crew changes and an assumption fills the gap.
Organizations that get it right plan for the handoff. Every worker’s lock, every shift change, every contractor briefing, and every zero-energy check is written into the procedure and verified in the field.
The Standards Navigator covers the OSHA rules, ANSI consensus standards, and ISO 45001 requirements behind energy control, construction safety, and shop floor compliance — in plain language, from people who have worked under them.
