Objective

The objective of this toolbox talk is to ensure that all employees understand the importance of hazardous energy control and the correct procedures for lockout/tagout (LOTO) to prevent injuries during servicing and maintenance of machines and equipment.

Introduction

This toolbox talk covers the safety procedures for hazardous energy control and lockout/tagout (LOTO) as per OSHA regulations. It is essential to understand and follow these procedures to prevent unexpected energization, start-up, or release of stored energy, which could cause serious injury or death.

Key Points

Identify Hazardous Energy Sources: Before starting any servicing or maintenance work, identify all potential sources of hazardous energy, including electrical, mechanical, hydraulic, pneumatic, chemical, and thermal energy.
Notify Affected Employees: Notify all affected employees before applying lockout/tagout devices. This includes informing them about the type of work being performed, the expected duration of the shutdown, and who is responsible for the LOTO procedure.
Proper Shutdown Procedures: Use the established shutdown procedures for the specific machine or equipment. This may involve turning off switches, closing valves, or disconnecting power sources. Ensure the shutdown process does not create additional hazards.
Isolate Energy Sources: Isolate the equipment from all energy sources by disconnecting or neutralizing them. This may involve disconnecting electrical circuits, blocking hydraulic lines, or bleeding pneumatic systems.
Apply Lockout/Tagout Devices: Affix lockout devices (locks) or tagout devices (tags) to all energy-isolating devices. Lockout devices provide a physical barrier, while tagout devices serve as a warning. If tagout is used where lockout is possible, additional safety measures are required.
Verify Isolation: After applying LOTO devices, verify that the equipment is completely de-energized and cannot be restarted. This may involve testing circuits, checking pressure gauges, or attempting to start the equipment.

Hazard Identification

Unexpected startup of machinery: Crushing injuries, amputations, or death
Release of stored energy (e.g., spring tension, hydraulic pressure): Impact injuries, lacerations, or burns
Electrical shock from energized circuits: Burns, electrocution, or cardiac arrest
Exposure to hazardous materials due to valve opening: Chemical burns, poisoning, or respiratory damage

Control Measures

Develop and implement a written energy control program: The program must include specific procedures for LOTO, employee training, and periodic inspections.
Use standardized lockout/tagout devices: Devices must be durable, identifiable, and used only for energy control.
Ensure proper training for all employees: Authorized employees must be trained in LOTO procedures, while affected employees must understand the purpose and importance of the program.
Conduct periodic inspections of LOTO procedures: Inspections must be performed at least annually by an authorized employee to identify and correct any deviations or inadequacies.

Personal Protective Equipment (PPE) Requirements

Eye Protection: Wear safety glasses or face shields to protect against flying debris or chemical splashes during the lockout process.
Electrical Gloves: Use insulated gloves when working with electrical equipment to prevent electrical shock.
Safety Boots: Wear appropriate work boots to protect feet from falling objects or sharp edges.

Real-World Example or Case Study

A maintenance worker was seriously injured when a conveyor system unexpectedly started up during repairs. The worker had not properly locked out the electrical disconnect, and another employee unknowingly re-energized the system. This incident highlights the critical importance of following LOTO procedures and verifying isolation before starting work.

Emergency Procedures

Immediately shut down the equipment if it can be done safely.
Provide first aid and seek medical attention for any injured personnel.
Report the incident to the supervisor and safety department for investigation and corrective action.

Questions and Answers

Q: What is the difference between authorized and affected employees?

A: Authorized employees are those who perform the lockout/tagout procedures. Affected employees are those who operate or work in the area where the procedures are being performed.

Q: Can lockout devices be used for other purposes?

A: No, lockout devices must never be used for any other purpose than energy control.

Summary

Recap of main points:

Hazardous energy control and LOTO procedures are essential for preventing injuries during servicing and maintenance.
Proper training, communication, and adherence to established procedures are critical for the success of the LOTO program.
Always verify isolation before starting work and ensure all employees are safely positioned or removed before re-energizing equipment.

Report all hazards, near-misses, and incidents to your supervisor immediately.
