Lockout/tagout (LOTO) procedures are crucial in maintaining a safe work environment for gas station personnel, especially when performing maintenance or repairs on equipment. These safety protocols help prevent accidents caused by the accidental release of energy from machines or systems. By following the proper steps, you ensure not only the safety of your employees but also compliance with safety regulations.

In this post, we'll walk you through the key principles of Lockout/Tagout procedures that every gas station should implement when working with hazardous energy sources. Whether you’re dealing with electrical systems, hydraulic or pneumatic equipment, or fluid/gas systems, these procedures are essential for preventing injuries and fatalities.

When performing maintenance on machinery or systems, it’s important to recognize that energy can come in various forms. The four primary types of energy that require lockout/tagout procedures are:

1. Electrical Energy: Power systems and circuits that supply energy to machinery.
2. Hydraulic or Pneumatic Energy: Pressure systems used to power equipment, often involving fluid or air.
3. Fluids and Gases: Gas lines or liquid pipelines that may contain pressurized fluids or gases.
4. Mechanical Energy: Stored energy in equipment like springs, rotating parts, or other mechanical devices.

Understanding these sources of energy is the first step in implementing effective lockout/tagout practices.

Lockout/Tagout Do’s: The Steps to Take

To ensure proper lockout/tagout procedures are followed, here are the key actions your team should take:

1. Job Hazard Analysis and Briefing

• Before beginning any work, perform a Job Hazard Analysis (JHA). This involves identifying potential risks and hazards associated with the task at hand.
• Brief all affected personnel on the job's scope and the necessary safety measures.

2. Locate and Identify Isolating Devices

• Ensure that all energy-isolating devices (e.g., switches, breakers, valves) are located and clearly identified. This will allow you to confirm which devices control the relevant equipment.

3. Notify Affected Employees

• Inform all employees that the system will be shut down. If possible, provide an estimated duration of the shutdown to manage expectations and ensure clear communication.

4. Isolate the Energy Sources

• Shut off all relevant energy sources, including electrical circuits, hydraulic/pneumatic systems, and mechanical energy sources. Use switches, breakers, or valves to fully isolate the system.

5. Dissipate Stored or Residual Energy

• Use methods like grounding, blocking, or repositioning to eliminate or control stored energy in devices like capacitors, springs, and rotating equipment.

6. Lock and Tag Energy-Isolating Devices

• Lock out all isolating devices that can accept locks. If a lock cannot be used (e.g., if the device is too small or doesn’t accommodate a lock), then apply a tag.
• Each lock should include information such as the employee’s name, date of application, and contact number.
• Tags should only be used if locks are not feasible.

7. Verification

• After isolating energy sources, verify that the equipment is properly de-energized by using controls like push buttons or other normal operating mechanisms to ensure that machines do not operate unexpectedly.

8. Use Multilock Hasps for Multiple Technicians

• When multiple technicians are involved, use multilock hasps. This ensures that each worker can apply their own lock and tag, maintaining individual control over the energy-isolating devices.

9. Final Check Before Restarting

• After maintenance is completed, ensure all tools are removed, and safety guards are reinstalled.
• Before re-energizing equipment, ensure all affected employees are clear of the equipment and ready for safe operation.

10. Inform Employees Before Removing Lock/Tag

• Notify all affected personnel when it’s safe to remove lockout/tagout devices and resume normal operations.

11. Restore Equipment to Service

• Carefully remove locks and tags, reset energy-isolating devices, and restore the equipment to its normal operating state.

Lockout/Tagout Don’ts: What to Avoid

There are certain critical errors that must be avoided to maintain the safety and integrity of the lockout/tagout process:

1. Don’t Remove Guarding Until De-energized
   • Never remove guards or safety covers from machinery until it is properly de-energized and locked out.
2. Don’t Work on Moving Equipment
   • Do not attempt to perform maintenance on machinery or systems that are in motion or have the potential to move unless fully de-energized.
3. Don’t Rely on Others for De-energizing
   • Always verify that equipment is properly de-energized yourself. Do not rely on others to disconnect or shut down a circuit for you.
4. Don’t Remove Someone Else’s Lock/Tag
   • Only the person who applied a lock or tag is authorized to remove it. Never remove another person’s lock or tag under any circumstances.
5. Don’t Assume Circuits Are Properly Labeled
   • Always test equipment to confirm that it has been properly de-energized. Never assume that electrical circuits or breakers are labeled correctly.
6. Don’t Disturb Electrical Locks/Tags
   • Do not tamper with electrical locks or tags. If you encounter issues, inform the appropriate personnel.
7. Don’t Share Locks or Keys
   • Locks and keys are strictly for individual use. Never loan or share them with others, as this could compromise safety and accountability.

Conclusion: Prioritize Safety at All Times

Lockout/tagout procedures are essential to ensuring the safety of your employees when working with dangerous energy sources. By following these clear steps—identifying energy sources, isolating systems, applying locks and tags, and verifying safe conditions—you help protect everyone involved in the maintenance process.

At your gas station, safety is paramount. Adhering to LOTO guidelines not only reduces the risk of accidents and injuries but also ensures that you comply with OSHA regulations. Always remember, safety first—every time, every task.
