Lockout

Lockout

Lockout is a method used to prevent the release of unsafe energy. For example, a safety lock can be placed on an off or closed-energy isolation device. The term "lockout" refers to the principle of properly shutting down a power resource, draining the pipes excess energy that may exist in the pipeline, and applying equipment to the energy source to prevent it from being energized.

All workers who repair and/or maintain equipment and are affected by unexpected power, starting, or unsafe starting power.

Lockout is to control hazardous energy by placing a lock or tag on the energy-isolating tool, indicating that the energy-isolating device cannot be operated until the lock or tag is removed.

In practice, the lockout is to isolate energy from the system (equipment, devices, or program) so that the system is in a safe setting. The energy isolation device can be a manually operated independent switch, a circuit breaker, a line closed, or a block. Buttons, option buttons, and various other circuit control buttons are not considered energy isolation devices.

The release of dangerous energy is controlled and protected by the energy isolation tool of the protection equipment. Examples of energy isolating devices are manual disconnect switches, circuit breakers, line breakers, or blocks. The lockout tool is usually as simple as a lock, but it can also be any protective energy isolation tool placed without risk.

A lock or lockout device is used to ensure the isolation of each power source so that the tool cannot be activated during the entire repair work or maintenance process. The device that can be used with the lock consists of a chain, a buckle, and a blind flange.

In unusual circumstances, padlocks cannot be used for specific devices. In these cases, there will certainly be other systems in place that will certainly provide a minimum of as much protection as lockout would. There are even some exceptions that do not need to be locked, for example, if the machine is one that can be disconnected while the plug is still under the control of an approved person.

Your company needs to have a documented lockout procedure that shows your company's policies and specific equipment in your workplace. However, an ordinary lockout process can be carried out like this:

1. The authorized person will definitely identify all the power resources and how to control them.

2. The approved personnel will notify all affected workers of the upcoming lockout procedures, including:

These devices are locked out of the door and labeled.

Why the device is locked and labeled.

How long do they expect the device to be out of use?

Affected employees can request more information.

3. The affected persons will leave the area, and the authorized personnel will:

Turn off the device.

Separate the system from unsafe electricity.

Throw away all the energy saved.

4. Everyone who maintains the equipment will use his own lock and tag.

5. The staff will definitely carry out the necessary maintenance of the equipment.

6. After the maintenance work is completed, the maintenance personnel will ensure that all tools and working materials are removed and that all employees stay in risk-free places away from hazardous areas.

7. All maintenance workers will definitely remove their locks and tags, and work together to ensure that no one is still dealing with the manufacturer.

8. Once everyone has left the manufacturer and all the locks and tags have been removed, the certified employee can reactivate the device, and then notify the affected employee that the repair has been completed and they can return to the workspace.
