Objective

To understand and apply Lockout Tagout procedures to safely isolate hazardous energy sources during maintenance and servicing.

Introduction

Lockout Tagout (LOTO) is a critical safety procedure designed to protect employees from the unexpected release of hazardous energy during maintenance or servicing of equipment. Failure to properly implement LOTO can lead to serious injuries or fatalities.

Key Points

• Importance of LOTO: LOTO procedures safeguard workers from hazardous energy releases during servicing and maintenance. Failure to control hazardous energy accounts for nearly 10 percent of serious accidents in many industries. Proper LOTO practices disable machinery and prevent hazardous energy release. [3] [3] [3]
• Authorized vs. Affected Employees: It's important to distinguish between authorized and affected employees. Authorized employees are those who perform the lockout/tagout procedures, while affected employees work in the area where the procedures are carried out. Both groups require specific training. [9] [9]
• Basic LOTO Steps: The basic steps include preparing for shutdown, notifying affected personnel, shutting down equipment, isolating the system, dissipating stored energy, applying lockout/tagout devices, and verifying isolation. [2] [2] [2] [2] [2] [4] [4]
• Lockout vs. Tagout: Lockout is the preferred method, involving a physical lock on the energy-isolating device. Tagout is used when lockout is not possible, employing a warning tag. When tagout is used, additional safety measures are required to provide equivalent protection to lockout. [7] [5] [5]
• Stored Energy: Always relieve, disconnect, restrain, or otherwise render safe all potentially hazardous stored or residual energy. If there is a possibility of re-accumulation of stored energy, verification of isolation shall be continued until the servicing or maintenance is completed. [6] [6]
• Periodic Inspections: Energy-control procedures must be inspected at least annually and certified in writing to ensure they are up-to-date and effective. [8]

Hazard Identification

• Unexpected Startup: Serious injury or death due to the sudden and unexpected activation of machinery or equipment.
• Electrical Shock: Electrocution or severe burns from contact with live electrical components.
• Crushing Injuries: Amputation or severe trauma from moving parts of machinery. [1]
• Release of Stored Energy: Injuries from the uncontrolled release of hydraulic, pneumatic, or spring energy.
• Chemical Exposure: Burns or poisoning from contact with hazardous chemicals in the system.

Control Measures

• Develop and implement equipment-specific LOTO procedures.: Create detailed, step-by-step procedures for each piece of equipment, identifying all energy sources and isolation points. [1]
• Use lockout devices whenever possible.: Prioritize lockout over tagout. Ensure energy-isolating devices are capable of being locked out. [5]
• Verify isolation before starting work.: Test the equipment to ensure it cannot be started up. Check for any residual or stored energy. [4] [4]
• Conduct regular LOTO training.: Provide comprehensive training to all authorized and affected employees. Retrain as needed to maintain proficiency. [3]
• Use standardized LOTO devices.: Ensure all locks and tags are durable, standardized, and clearly identify the authorized employee. [8]
• Address group lockout situations.: Establish procedures for group LOTO, ensuring each employee has their own lock and is accounted for. [1]

Personal Protective Equipment (PPE) Requirements

• Safety Glasses: Always wear safety glasses to protect your eyes from debris or chemical splashes.
• Gloves: Use appropriate gloves (e.g., electrical, chemical-resistant) to protect your hands from hazards.
• Safety Shoes: Wear safety shoes to protect your feet from falling objects or electrical hazards.
• Hearing Protection: Use hearing protection in noisy environments to prevent hearing damage.

Group Discussion

Discuss the following questions:

1. Who is authorized to perform LOTO on specific equipment?
2. What are some potential sources of stored energy in our equipment?
3. What steps should be taken if you find a machine that is not properly locked out?

Emergency Procedures

1. Immediately shut down the equipment if safe to do so.
2. Evacuate the area and ensure everyone is accounted for.
3. Contact emergency services and provide details of the incident.

Summary

Recap of main points:

• LOTO is essential for preventing injuries during equipment maintenance and servicing.
• Always follow established LOTO procedures and use appropriate devices.
• Verify isolation before starting work and address any potential stored energy.
• Report any LOTO-related concerns or issues immediately.

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