A Facility Manager's Guide to Lockout/Tagout
How to close dangerous gaps, avoid OSHA citations, and modernize your LOTO program with the right devices.
Lockout/Tagout (LOTO) remains one of OSHA’s Top 10 most frequently cited standards year after year. In preliminary Fiscal Year 2025 data, it ranked #4 with over 2,100 violations, while FY 2024 saw nearly 2,500 citations and millions in penalties.
Behind these numbers are often foundational gaps: incomplete machine-specific procedures, inadequate training, or missing annual inspections. But even facilities with solid written programs can face real-world failures when lockout devices don’t fit properly, aren’t durable enough, or aren’t readily available. This can lead to bypasses, improper application, and heightened risk.
This guide helps you assess your program’s strengths and weaknesses, identify overlooked energy sources, and select exact-fit devices to make compliance practical and effective.
Lockout Vs. Lagout
OSHA strongly prefers lockout over tagout whenever an energy-isolating device can accept a lock, because locks provide superior physical prevention of energization (29 CFR 1910.147(c)(3)). Tagout is permitted only when lockout is not feasible, and employers must demonstrate equivalent protection through full tagout compliance plus additional measures such as removing an isolating circuit element, blocking a controlling switch, opening an extra disconnect, or removing a valve handle. Prioritizing lockout-capable devices and retrofitting equipment where possible delivers the highest level of employee safety and aligns with OSHA’s intent.
Common LOTO Citation Drivers (Based on OSHA data)
Machine-specific procedures incomplete or missing (c)(4)
Insufficient training/retraining (c)(7)
No/lacking annual inspections (c)(6)
Improper device application/verificaton/isolation (d)
Note: While devices themselves are rarely the top-cited issue, ill-fitting or substandard ones often contribute to application failures.

5. Is training comprehensive, up-to-date, and provided for authorized, affected, and other employees with retraining as needed?
Score:
9-10 'Yes ' Answers: ✅ Low Risk Top-tier LOTO program
You’re in great shape. Keep devices maintained, audits current, and continue reinforcing safe behaviors.
7-9 'Yes ' Answers: ⚠️ Medium Risk Solid base, but real gaps exist
Focus on closing the gaps in the answers, especially missing devices, incomplete energy mapping, and outdated procedures.
1-6 'Yes' Answers: ❗ High Risk High risk of injury or citation
Start by mapping all energy sources, ensuring each has a correctly sized lockout device, and updating your written LOTO program.
Q:
7. Are affected employees notified before applying and before removing lockout/tagout devices?
Q:
8. Is release from lockout/tagout performed safely, with area inspection, employees positioned safely, and notification prior to re-energization?
Q:
8. Is release from lockout/tagout performed safely, with area inspection, employees positioned safely, and notification prior to re-energization?
Q:
9. Are procedures in place for special scenarios, such as group lockout, shift changes, temporary re-energization for testing, and coordination with contractors?
Q:
10. Does your program address all forms of hazardous energy (electrical, mechanical, hydraulic, pneumatic, chemical, thermal, gravity, etc.) and properly apply any exceptions?
When determining whether you have the correct types and enough lockout devices for your facility, follow these simple yet effective steps to ensure full coverage and compliance:
Step 1: Map Every Source of Hazardous Energy
You can't protect what you haven't mapped, Before you worry about tags, padlocks, or procedures, you need a complete inventory of every hazardous energy source in your facility.
During your walk-through, make sure you capture more than only the main disconnects. Most LOTO gaps come from secondary or non-traditional sources that work in the corners of the plant.
Commonly overlooked sources include:
Electrical panels, and disconnects non-local, stored electricity
Pneumatic quick-connects and hydraulic lines
Mechanical hazards (flywheels, springs, counterweights, chain drives)
Gravity hazards (raised loads, suspended equipment, vertical lifts)
Thermal hazards (steam valves, hot oil lines, heated piping)
Stored pressure (accumulators, gas cylinders)
Involve maintenance, engineering, and operators in a facility walk-through. One unidentified isolation point can compromise an entire procedure.
Step 2: Match the Correct Lockout Device to Every Energy Source
‘Close enough’ devices invite bypasses and noncompliance. Either a device is securely lockout out or it isn't. Always select devices that provide an exact, secure fit to prevent removal without proper authorization.
Step 3: Build or Refresh a Bulletproof LOTO Program
Your program must include, at minimum:
A comprehensive energy control program
Machine-specific energy control procedures
Employee training and communication
Appropriate lockout devices
Annual audits and inspections
