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—leading 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.

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.

Important Note on Lockout vs. Tagout

OSHA strongly prefers lockout over tagout whenever an energy-isolating device is capable of accepting 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.

60-Second LOTO Health Check (Take It Right Now)

OSHA’s standard 29 CFR 1910.147, The Control of Hazardous Energy (Lockout/Tagout), establishes requirements for protecting employees during servicing and maintenance. Use these 10 questions—drawn from the standard’s core elements—to evaluate your program.

Answer Yes or No — be honest:

1. Do you have a documented energy control program tailored to your workplace’s specific hazards?

2. Is all applicable equipment capable of being locked out, with new or modified equipment designed to accept lockout devices?

3. Are lockout/tagout devices durable, standardized (by color, shape, or size), substantial, and identifiable?

4. Do you conduct and certify annual periodic inspections of energy control procedures, correcting any deficiencies?

5. Is training comprehensive, up-to-date, and provided for authorized, affected, and other employees—with retraining as needed?

6. Are machine-specific energy control procedures followed step-by-step, including shutdown, isolation, device application, stored energy release, and verification of zero energy state?

7. Are affected employees notified before applying and before removing lockout/tagout devices?

8. Is release from lockout/tagout performed safely, with area inspection, employees positioned safely, and notification prior to re-energization?

9. Are procedures in place for special scenarios, such as group lockout, shift changes, temporary re-energization for testing, and coordination with contractors?

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 sufficient quantities of 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 cmoplete inventroy of every hazardous energy source in your facility.

During your walk-through, make sure you capture more than just hte main disconnects.  Most LOTO gaps come from secondary or non-traditional sources that live 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

The most impactful improvements often come from addressing OSHA's most frequently cited LOTO deficiencies:

  • Machine-specific procedures incomplete or missing → 1910.147(c)(4) (historically the #1 cited provision)
  • Insufficient training/retraining → 1910.147(c)(7)
  • No/lacking annual inspections → 1910.147(c)(6)
  • Improper device application/verification/isolation → 1910.147(d)

Additionally, ensuring exact-fit devices at every isolation point and organizing them for easy access supports effective application and reduces errors.
