Lock tag and try is an essential safety process that ensures equipment maintenance is performed without the risk of unexpected energization or hazardous energy releases. This three-part procedure—comprising locking, tagging, and trying—provides an effective way to prevent serious injuries and safeguard workers when dealing with industrial equipment and hazardous energy sources.
Proper implementation of Lockout - Tagout (LOTO) procedures during maintenance work not only enhances workplace safety but also ensures compliance with regulatory requirements.
Understanding the Lock Tag and Try Procedure
The Importance of Energy Control Procedures
Lock, tag, and try (LTT) focuses on controlling hazardous energy sources during maintenance or repair tasks. Whether you're handling electrical equipment, chemical energy, or thermal energy, implementing an energy control procedure is vital to protect authorized workers, affected employees, and anyone else in the work area.
The process starts with the identification of energy sources and isolation points.
Locking devices and tagout devices are then applied to energy-isolating devices such as circuit breakers, control switches, or power sources to secure them in a safe position. This ensures the isolation of energy and eliminates the risk of residual energy or unexpected energization that could harm maintenance personnel.
Steps in Lock, Tag, and Try
Risk Assessment and Isolation: Conduct a thorough risk assessment to identify specific hazards and determine the types of energy involved (e.g., electrical energy or stored energy). Locate energy-isolating devices at isolation points to disconnect power sources.
Apply Locking and Tagging Devices: Use lockout devices and safety tags to secure the isolation device. Ensure tags prominently display warnings to inform affected individuals and authorized workers about the maintenance activity. Personal locks are often employed at this stage for additional safety and accountability measures.
Tryout Procedures (Verification): The final and most critical step involves zero energy verification. Authorized workers must test the equipment to ensure all sources of energy, including residual energy, are fully disconnected. This step is crucial for preventing electrical hazards, chemical energy leaks, or other unexpected equipment activity.

Best Practices for Implementing Lock, Tag, and Try
Specific Guidelines and Qualified Taggers
To effectively implement a LOTO procedure, workplaces should provide clear, specific procedures tailored to individual machines and systems. Qualified taggers must be trained to identify isolation devices, apply safety devices correctly, and follow tagout procedures that align with regulatory standards.
Follow periodic review processes to ensure compliance and update guidelines based on evolving risks or changes in equipment. Detailed documentation of lockout procedures and their application to specific hazards can significantly boost safe outcomes.
Enhancing LOTO Procedures With Safety Devices
A variety of safety tags and locking devices should be made available to meet the needs of different equipment types and hazards. For example, circuit breakers require specialized lockout devices, while thermal or electrical energy sources may need customized isolation to address specific hazards. Consistently using these safety measures helps address the control of hazardous energy and safeguards workplace operations.

The Role of LockBoard in Enhancing Maintenance Safety
Having the right tools and equipment on hand is key to successfully implementing LOTO procedures. That’s where LockBoard comes in. Offering a single, innovative product—a Lockout - Tagout board—it provides an organized and reliable way to manage lockout devices, safety tags, and energy isolation tools.
This centralized approach is especially useful for maintenance work in industrial settings. Maintenance teams can use the board to ensure all lockout devices are properly stored, accessible, and ready to be deployed. By simplifying energy control procedures and supporting zero energy verification processes, the LOTO board enables heightened safety during maintenance and repair machinery tasks.

Ensuring Safer Maintenance Through Lockout - Tagout
Addressing Specific Hazards
Every worksite has unique challenges and risks. Some types of energy, such as electrical energy or stored energy, may require the use of multiple isolation points or alternative control methods. A good LTT, aka LOTO (Lockout/Tagout/Tryout), program supports these needs while addressing both the technical and procedural aspects of maintenance safety.
Promoting Employee Safety and Compliance
Through regular training and implementation of LOTO procedures, workplaces can minimize safety issues and promote occupational safety. Ensuring all workers—authorized, affected employees, and qualified taggers—understand their roles enhances overall compliance and reduces accidents.
By following these specific guidelines and employing the best tools, such as those from LockBoard, workplaces can achieve success in isolating energy, controlling risks, and maintaining safety during maintenance operations. Safe maintenance practices start with lock tag and try, a process that ensures every step of the job is performed with the utmost precision and protection.
