Effective Lockout Tagout (LOTO) procedures are critical for ensuring the safety of employees who work with or around hazardous machinery and equipment. Not only that, but writing clear, detailed, and actionable LOTO procedures can help to prevent accidents, injuries, and costly downtime. Additionally, it can improve safety, compliance, and efficiency in the workplace. Because of this, it is worthwhile to develop quality procedures. This article dives into the key elements of LOTO and tips for writing better lockout tagout procedures.

A lockout tagout procedure is a set of equipment-specific safety steps that should be followed in order to safely shut down, de-energize, and secure machinery with hazardous energy. The purpose of lockout tagout procedures is to provide a framework for controlling hazardous energy and preventing accidental startup of machinery or equipment, which could lead to serious injuries or fatalities.

When writing lockout tagout procedures, it is essential to include all of the information that will be needed during the LOTO process. Often, lockout tagout procedures are broken up into sections of information that the reader can digest and implement as they go through the stages of shutting down and securing the equipment. 

Here are the key elements that should be included in any and all lockout tagout procedures and what information they should provide.

1. Scope, Purpose, and Authorization 

This section defines the range and objective of the LOTO procedure and specifies who is authorized to perform and oversee the lockout process. Specifying authorization and the type of lockout ensures that only trained and competent individuals perform and oversee LOTO procedures. This reduces the risk of errors and enhances accountability.

2. Lockout / Tagout Application Steps 

The lockout / tagout application process portion of procedures provides a detailed, step-by-step guide on how to safely apply lockout and tagout devices to isolate hazardous energy sources. Clear instructions minimize the risk of errors, ensuring that all necessary steps are completed in the correct order, thus preventing accidental energization.

Detailed steps ensure that every worker follows the same procedure, maintaining consistency and compliance with safety regulations. Each step included in this section is designed to systematically eliminate potential hazards, ensuring that all energy sources are properly isolated before maintenance begins.

3. Equipment Pictures 

Visual aids, such as pictures of the equipment and energy isolation points, are included in the procedure. These can help the authorized worker(s) quickly identify the correct equipment and isolation points, reducing the chance of mistakes.

The purpose of visual aids is to complement written instructions, making it easier for workers to understand and follow the procedure. They can also be valuable for training new employees by helping them become familiar with the machinery and its components.

4. Energy Identification and Isolation 

This section identifies the energy source type, details where it is found, and gives direction for isolating the energy source and verifying it has been correctly shut off. 

The “Energy Identification and Isolation” section provides crucial information to the worker by identifying all necessary hazardous energy sources and how to safely prevent accidental release of energy. This way, workers can create a safe environment to work in, protecting themselves and others from unexpected energization. 

5. Return to Service Steps / Lock and Tag Removal Process 

This section outlines the steps for 2 key processes: safely removing lockout tagout devices and returning the equipment to normal operation. 

The instructions outlined in this section should clearly indicate important steps such as verification that maintenance is complete, notifying affected employees before removing LOTO devices, and how to correctly re-energize the machinery. By providing simple guidance for removing lockout devices and returning equipment to service, companies help ensure that the machinery is safely transitioned back to operational status without risking worker safety.

**Note: Some lockout tagout procedures also include a QR code that can be scanned and used alongside software to record loto steps as they are performed. 

Each element of written lockout tagout procedures plays a crucial role in ensuring the safety of workers and effectiveness of the LOTO process.

OSHA 1910.147 The Control of Hazardous Energy (Lockout/Tagout) is a safety standard that has been established by the Occupational Health and Safety Administration outlining what companies and organizations need to know to maintain compliance for lockout tagout. This standard clearly states that employers are required to “establish a program and utilize procedures for affixing appropriate lockout devices or tagout devices to energy isolating devices, and to otherwise disable machines or equipment to prevent unexpected energization, start-up or release of stored energy in order to prevent injury to employees.”

The standard goes into further depth on procedures by stating that procedures should be “developed, documented and utilized for the control of potentially hazardous energy when employees are engaged in the activities covered by this section” (lockout tagout). 

There is an exception to this rule, however, it comes with a number of specific criteria. 

Exception as stated by OSHA: “The employer need not document the required procedure for a particular machine or equipment, when all of the following elements exist: 

(1) The machine or equipment has no potential for stored or residual energy or reaccumulation of stored energy after shut down which could endanger employees; 

(2) the machine or equipment has a single energy source which can be readily identified and isolated; 

(3) the isolation and locking out of that energy source will completely deenergize and deactivate the machine or equipment; 

(4) the machine or equipment is isolated from that energy source and locked out during servicing or maintenance; 

(5) a single lockout device will achieve a locked-out condition; 

(6) the lockout device is under the exclusive control of the authorized employee performing the servicing or maintenance; 

(7) the servicing or maintenance does not create hazards for other employees; and 

(8) the employer, in utilizing this exception, has had no accidents involving the unexpected activation or re-energization of the machine or equipment during servicing or maintenance.”

For any situations involving lockout tagout that do not meet all 8 stipulations above, the following guidance from (1910.147(c)(4)(ii) should be adhered to for the writing and usage of lockout tagout procedures. 

Section (1910.147(c)(4)(ii) specifies that procedures should outline the scope, purpose, authorization, rules, and techniques for controlling that source of hazardous energy. 

In order to write compliant lockout tagout procedures, the procedures should at least include the following information: 

• A statement specifying the intended use of the procedure
• Procedural steps for the shut down, isolation, blocking and security of machines or equipment to control hazardous energy;
• Detailed procedural steps for the placement, removal and transfer of lockout devices and tagout devices and the responsibility for them; and
• Requirements for testing a machine/equipment to verify the effectiveness of lockout devices, tagout devices, and other energy control measures.

When it comes to improving procedures, one of the best practices is to write with the end user in mind. 

After all, lockout tagout procedures should be written so that any authorized employee can properly perform their duties. Procedures are meant to equip users with adequate knowledge and information to safely perform their responsibilities with confidence. The following tips are all ways that the procedure author can write lockout tagout procedures with the worker(s) that will use them in mind.

• Tip: Become acquainted with the process that workers undergo when actually performing lockout tagout procedures. 
• Why it Matters: Familiarity with the process will help with organizing the necessary information in a way that flows for the worker.  
  • Typically, lockout tagout procedures look a little something like this:
    • 1. Prep for Shutdown & Notify Affected Employees
    • 2. Equipment Shutdown
    • 3. Isolation of Energy Sources
    • 4. Lockout Tagout Device Application 
    • 5. Dissipation of Residual or Stored Energy
    • 6. Verification of Isolation
    • 7. Performing Maintenance or Servicing
    • 8. Release from Lockout Tagout 
    • 9. Equipment Restart
    • 10. Documentation and Recordkeeping

• Best Practice: Create a detailed equipment inventory and document the specific energy sources for each machine. This ensures your procedures are tailored to the exact equipment and energy hazards in your facility.

• Tip: Use clear, simple, and concise language when writing LOTO procedures. Avoid technical jargon that could confuse workers, especially those who are not engineers or technical experts.
• Why It Matters: LOTO procedures are typically used by workers under time constraints or stress. Overly complex language can lead to misunderstandings or incorrect implementation of procedures, increasing the risk of accidents.
• Best Practice: Break down each step in the procedure into clear, actionable instructions. Use bullet points or numbered lists to make the process easy to follow

• Tip: Incorporate visuals such as diagrams, photos, and flowcharts into your LOTO procedures to help clarify complex steps.
• Why It Matters: Workers may better understand how to isolate energy sources or lock out machinery when they can see clear visuals. Diagrams showing the location of switches, valves, or lockout points can reduce confusion and ensure accuracy.
• Best Practice: Include labeled diagrams or photographs of the actual machinery, highlighting the key components that must be locked out. This can be especially helpful for large or complex equipment where key control points might not be immediately obvious.

• Tip: Ensure that each piece of equipment has a unique, equipment-specific LOTO procedure. Avoid using generic templates for all machinery, as different equipment requires different steps to control hazardous energy.
• Why It Matters: A one-size-fits-all approach doesn’t work when dealing with the varied types of machinery in a facility. A procedure that works for one machine might not apply to another, leading to unsafe practices or missed steps.
• Best Practice: Tailor LOTO procedures to each machine by documenting the exact steps needed to safely shut down, isolate energy, and verify de-energization for that specific piece of equipment.

• Tip: Identify and define who is responsible for each step of the LOTO process, including the roles of authorized employees, affected employees, and supervisors.
• Why It Matters: Defining roles ensures that everyone involved knows their specific responsibilities, reducing confusion and the potential for errors. Authorized employees need to know exactly what actions to take, while affected employees need to understand when and why equipment is locked out.
• Best Practice: Include a section in each LOTO procedure that outlines the roles of all involved parties, specifying who is authorized to apply and remove locks and who should be notified.

• Tip: Carefully outline the exact sequence of steps that need to be followed when locking out equipment, and emphasize the importance of verification after applying locks.
• Why It Matters: Following the correct sequence of actions ensures that all energy sources are effectively isolated. Verification is crucial for confirming that energy has been properly controlled before work begins, ensuring no hazardous energy remains.
• Best Practice: Provide a step-by-step process that starts with shutting down equipment, followed by isolation and lockout of each energy source, and ends with verification to ensure that equipment cannot be accidentally restarted.

• Tip: If your facility has equipment that requires multiple workers to perform maintenance, be sure to incorporate group lockout procedures that account for multiple locks and personnel.
• Why It Matters: Group lockout ensures that each worker involved in the maintenance process applies their own lock, preventing accidents by ensuring that the machine cannot be re-energized until all workers have completed their tasks.
• Best Practice: Develop clear group lockout procedures that specify how locks will be applied, managed, and removed. Use a lockbox system if necessary to manage group lockout situations effectively.

• Tip: Include procedures for managing shift changes or personnel transitions during a LOTO process, ensuring continuity in lockout control between shifts.
• Why It Matters: Equipment may remain locked out across multiple shifts, and without clear procedures, there is a risk of unauthorized removal of locks or incomplete lockout transfers. This can result in dangerous situations if workers assume machinery is safe when it isn’t.
• Best Practice: Develop a formal process for transferring lockout control, ensuring that incoming personnel verify the lockout status and understand the work in progress.

• Tip: Make it a priority to periodically review and update LOTO procedures to ensure they remain accurate and up to date with current equipment and regulations.
• Why It Matters: Machinery and work processes change over time, and regulations may be updated. Outdated procedures can lead to safety lapses or non-compliance with industry standards.
• Best Practice: Schedule annual reviews of all LOTO procedures and make necessary updates as equipment or operational changes occur. Keep an audit trail of any revisions made.

• Tip: Ensure all employees are properly trained in the LOTO procedures and receive periodic retraining to reinforce their knowledge.
• Why It Matters: Even well-written procedures won’t be effective if workers don’t understand them or fail to follow them. Ongoing training ensures that employees stay aware of the procedures and are comfortable implementing them correctly.
• Best Practice: Provide comprehensive training sessions for all employees who are involved in LOTO, and conduct regular refresher courses to keep everyone up to date. Incorporate hands-on training whenever possible to reinforce proper procedure execution.

• Tip: Where possible, use updated technology and equipment to write, perform, and document lockout tagout procedures.  
• Why it Matters: Technology can offer a variety of benefits for LOTO programs including help with writing procedures, a centralized place for storing data, and more accurate record keeping. 
• Best Practice: Invest in and incorporate software that can aid in managing the LOTO program. Train users on how to best use the software. Additionally, review documents to recognize trends, areas of improvement, and other valuable insights.
