Objective

To understand and apply Lockout/Tagout (LOTO) procedures to ensure equipment is safely de-energized during maintenance and servicing, preventing unexpected start-ups and hazardous energy release.

Introduction

Lockout/Tagout (LOTO) is a critical safety procedure designed to protect employees from the dangers of unexpected machine or equipment energization, start-up, or release of stored energy during servicing or maintenance. Failure to properly implement LOTO can lead to severe injuries or fatalities.

Key Points

• Importance of LOTO: LOTO procedures are essential for preventing accidental machine start-up or release of stored energy during maintenance and servicing. This protects employees from potential injuries such as electrocution, crushing, and amputation.
• Authorized vs. Affected Employees: An 'authorized employee' is one who performs the lockout/tagout procedures on machines or equipment for servicing or maintenance. An 'affected employee' operates or works in an area where such servicing or maintenance is taking place. [10] [10]
• Energy Isolation: Identify all energy sources (electrical, mechanical, hydraulic, pneumatic, chemical, thermal, etc.) and use energy-isolating devices to physically prevent the transmission or release of energy. [6] [6]
• Lockout/Tagout Devices: Use standardized lockout devices (locks) or tagout devices (tags) to secure energy-isolating devices in a safe position. These devices must be durable, identifiable, and substantial enough to prevent removal without excessive force. [2] [2] [2] [2] [2] [2]
• Verification of Isolation: Before starting work, verify that the machine or equipment is properly isolated and de-energized. This may include testing circuits, checking gauges, and attempting to start the equipment. [5]
• Group Lockout/Tagout: When a group performs servicing/maintenance, use a procedure that provides equivalent protection to personal lockout/tagout. Assign primary responsibility to an authorized employee, ensure individual exposure status is ascertained, coordinate multiple work groups, and require each authorized employee to affix a personal LOTO device. [1] [1] [1] [1] [1]
• Shift Changes: Specific procedures must be in place to ensure the continuity of LOTO protection during shift or personnel changes, including the orderly transfer of LOTO devices between off-going and oncoming employees. [11]
• Periodic Inspections: Conduct periodic inspections of energy control procedures at least annually to ensure the procedures are being followed and to correct any deviations or inadequacies identified. [8] [8]
• Training: Provide comprehensive training to authorized and affected employees on the purpose, function, and safe application of the energy control program. Retraining is required when job assignments change, new hazards are introduced, or inspections reveal inadequacies. [14] [9] [9]
• Tagout System Limitations: If using a tagout system instead of lockout, understand that tags are warning devices and do not provide physical restraint. Additional safety measures are required to achieve equivalent safety to a lockout system. [13] [4] [4]
• Outside Servicing Personnel: When outside servicing personnel are involved, the on-site and outside employers must inform each other of their respective LOTO procedures and ensure compliance. [7] [1]

Hazard Identification

Identifying potential hazards associated with machinery and equipment is crucial before performing any servicing or maintenance.

• Unexpected machine start-up: Severe crushing injuries, amputations, or death.
• Release of stored energy (electrical, mechanical, hydraulic, pneumatic, thermal): Burns, electrocution, crushing injuries, or other serious injuries.
• Failure to properly isolate energy sources: Exposure to hazardous energy, resulting in injury or death.
• Inadequate training on LOTO procedures: Incorrect application of LOTO, leading to potential accidents and injuries.
• Bypassing or removing safety devices: Increased risk of injury due to lack of protection from moving parts or hazardous energy.

Control Measures

• Develop and implement equipment-specific LOTO procedures.: Create detailed, step-by-step procedures for each machine or piece of equipment, outlining how to safely de-energize, isolate, and lock out all energy sources.
• Use appropriate lockout/tagout devices.: Ensure that locks, tags, and other hardware are readily available, standardized, durable, and properly used to secure energy-isolating devices. [12]
• Verify energy isolation.: After applying LOTO devices, always verify that the machine or equipment is completely de-energized by testing circuits, checking gauges, and attempting to start the equipment. [5]
• Provide comprehensive training.: Train all authorized and affected employees on LOTO procedures, energy hazards, and the importance of following safety protocols. [14]
• Conduct periodic inspections.: Regularly inspect LOTO procedures and practices to identify and correct any deviations or inadequacies. [8]
• Maintain clear communication.: Ensure clear communication between all employees involved in the servicing or maintenance activity, especially during group LOTO and shift changes.

Personal Protective Equipment (PPE) Requirements

• Safety Glasses: Wear safety glasses to protect eyes from potential hazards such as debris or splashes during maintenance activities.
• Gloves: Use appropriate gloves (e.g., electrical, chemical-resistant) to protect hands from electrical shock, cuts, abrasions, or chemical exposure.
• Safety Shoes: Wear safety shoes with steel toes to protect feet from falling objects or crushing hazards.
• Hearing Protection: Use hearing protection (earplugs or earmuffs) in noisy environments to prevent hearing damage.

Real-World Example or Case Study

A maintenance worker was seriously injured when a conveyor belt unexpectedly started while he was performing repairs. The machine was not properly locked out, and stored energy was not released, resulting in the worker's hand being crushed. This incident highlights the critical importance of following LOTO procedures to prevent such accidents.

Emergency Procedures

1. Immediately stop work and de-energize the equipment if an unexpected start-up or energy release occurs.
2. Evacuate the area and notify supervisors or emergency responders.
3. Provide first aid to any injured personnel and seek medical attention.

Questions and Answers

Here are some common questions and answers regarding Lockout/Tagout procedures:

• Q: Who is authorized to perform LOTO?

A: Only trained and authorized employees are permitted to perform LOTO procedures.

• Q: What do I do if I see a machine that should be locked out but isn't?

A: Immediately report it to your supervisor and do not operate the machine until it is properly locked out.

• Q: Can I remove someone else's lock or tag?

A: No, only the employee who applied the lock or tag is authorized to remove it, unless specific procedures for lock removal are followed under the direction of the employer. [3]

Summary

Recap of main points:

• Lockout/Tagout procedures are vital for preventing injuries during equipment maintenance and servicing.
• Proper training, equipment-specific procedures, and verification of energy isolation are essential for effective LOTO.
• Always follow LOTO procedures and never bypass or remove safety devices.
• Report any LOTO violations or unsafe conditions to your supervisor immediately.

Action Items

Specific actions participants should take:

1. Review and understand the LOTO procedures specific to your work area and equipment.
2. Participate actively in LOTO training sessions and ask questions to clarify any uncertainties.
3. Always verify energy isolation before starting any maintenance or servicing work.
4. Report any unsafe conditions or LOTO violations to your supervisor immediately.

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