Lockout tagout safety is essential for conducting service or maintenance of equipment. Hazardous energy, which might have caused accidents during equipment maintenance, can be controlled by adopting logout tagout safety procedures.

What Is Lockout Tagout?

Lockout Tagout (LOTO) is a safety practice and procedure that ensures machines and equipment are isolated from their energy sources during maintenance and service activities. The proper lockout tagout safety procedures confirm that equipment can not release unexpected hazardous energy during maintenance activity.

Lockout Tagout Examples:

  • A team consisting of two workers is servicing a machine, and at the same time, the Internal wiring of the equipment gets short-circuit, causing the maintenance team to get an electric shock.
  • Workers are performing maintenance activities on roller conveyors. In the meantime, the concerned operator started the conveyors, causing workers to receive hand injuries due to trapping their hands between the conveyor’s rollers.
  • Maintenance workers are doing the repair work of piping, and another worker, who is unaware of this activity, opens the valve of the same pipeline, sending fluids down the pipe, which ultimately spills on the maintenance workers, causing the maintenance team to receive injuries.
  • One team is performing their assigned task of clearing a jammed conveyor. During the process, jams cleared suddenly and unexpectedly, causing workers to get crushed.
  • One electrician is engaged to take the connection from the electric panel board. During the termination of the cable, someone switches on the power supply, causing the electrician to receive an electric shock.

These all are lockout tagout examples that do not follow lockout tagout safety procedures, causing injuries. Noncompliance with LOTO safety procedures can lead to injury and even fatality. Lockout tagout safety procedures always protect the workers from hazardous energy.

Top 7 Steps For Lockout Tagout Safety Procedures

The top 7 steps for logout tagout safety procedures have been explored in this article, which can assist you in the safe maintenance or services of equipment. These steps you can follow while performing logout tagout procedures.

The logout tagout safety procedures must include the following seven steps:

  1. Preparation
  2. Shutdown of Equipment
  3. Isolation
  4. Lockout And Tagout
  5. Verified Stored Energy
  6. Verification of Isolation
  7. Ensure Close Supervision

1 Preparation

Preparation is the first step of locking and tagging out the equipment for maintenance or service. During the preparation process, all hazardous energy sources must be identified by authorized personnel that might be controlled by implementing remedial control measures. Also, all persons involved must be trained in lockout tagout training courses.

2 Shutdown of Equipment

In this phase, The equipment or the machine that will be serviced or maintained shall be shut down completely. Another crucial part of this step is to inform all persons who might be affected by this shutdown, even if they are not a part of the maintenance or services. Examples of affected persons could include equipment or machine operators, who must know that equipment is under service and should not be operated.

3 Isolation

The third and most crucial step of locking & tagging out procedures is to isolate the equipment or machine from any sources of energy before the commencement of their maintenance or service activity. This can be done by switching off the power at the breaker or shutting a valve with proper lock and tag.

4 Lockout And Tagout

The next step of lockout & tagout procedures is to lock and tag out the equipment or machine. During this step, authorized personnel will attach lockout & tag-out the devices to each energy-isolating device. The purpose of locking out of an isolated device is to avoid the unexpected operation of equipment or machines by unauthorized personnel.

Tagout refers to fixing a tag on the lockout device. This tag can include some crucial information, such as the name & contact of the person who performed the lockout and additional information.

5 Verify Stored Energy

Equipment is shut down, isolated from the energy source, and lockout tagout has been attached in step 4 of lockout tagout safety procedures, but even this doesn’t completely guarantee that there is no hazardous energy stored within the machine or equipment. Always verify the ZERO ENERGY before starting the maintenance and service activity of machines or equipment.

At this stage, It’s crucial to look for stored or residual hazardous energy that might have been stored within the equipment or machine. During this process, all potential stored/residual energy must be relieved, disconnected, or restrained to ensure that there is no stored or residual energy within the equipment or machine.

6 Verification of Isolation

Step 6 of lockout tagout safety procedures verifies that you have shut down the machines, isolated them from their energy source, locked & tagged them out, and verification is done for hazardous stored energy. Now it is time to recheck to ensure that you have done these all right and safe to perform maintenance or service on the equipment or machine.

Here, An authorized person will verify that equipment or machines are isolated from their energy sources and de-energized.

7 Close Supervision

Once all the above six steps of logout tagout safety procedures are implemented, close supervision must be provided to ensure that lockout tagout safety procedures are being followed by the involved workforce throughout the jobs. Responsible supervisors must also ensure that all workers involved in maintenance activity must be trained & comply with PPE requirements.

Conclusion

Lockout Tagout is an essential safety procedure to ensure the safety of workers by separating them from hazardous energy during machines and equipment maintenance activity. Failure to comply with lockout tagout safety procedures can cause significant accidents, leading to injuries and even fatalities. Always ensure zero energy of equipment before performing any maintenance or service activity.
