Clarify equipment information: Confirm the name, model, location, and associated systems (such as power supply, air supply, hydraulic source, etc.) of the equipment requiring LOTO operations

Identify energy sources: List all potential energy sources of the equipment (electrical, mechanical, hydraulic, pneumatic, thermal, etc.), and mark the location and type of each energy source.

Prepare tools: Prepare standard-compliant locks, tags, isolation devices (such as circuit breakers, valves, etc.), keys, warning signs, etc.

Inform equipment operators, maintenance personnel, personnel in upstream and downstream processes in advance, specifying the time, scope, and precautions of the LOTO operation to ensure that irrelevant personnel stay away

Stop the equipment according to the normal shutdown procedure, ensuring that the equipment is completely stopped (e.g., the motor stops running, the conveyor belt is stationary, etc.).

Take physical isolation measures for the identified energy sources:

Electrical systems: Turn off the circuit breaker, unplug the power plug, and lock the circuit breaker.

Pneumatic/hydraulic systems: Close the air/hydraulic valve, release residual pressure in the pipeline, and then lock the valve.

Mechanical systems: Use clamps to fix moving parts (such as flywheels, sliders) to prevent accidental movement.

On the control devices at each isolation point (such as circuit breakers, valves), hang tags with information like "Under maintenance, do not operate" and "In LOTO". Use personal dedicated locks (one lock per person, with keys kept by the individual) to lock them, ensuring they cannot be opened arbitrarily.

Attempt to start the equipment (e.g., press the start button, operate the control lever) to confirm that the equipment shows no movement and the energy sources have been completely cut off.

For equipment with residual energy (such as capacitors, springs), take release measures (e.g., discharge, unload) and verify again.

After confirming that the energy isolation is effective, start the scheduled work. Do not remove locks or tags without authorization during the work.

After the work is completed, clean up the site, remove tools and obstacles, and ensure there are no safety hazards around the equipment.

Notify all personnel involved in LOTO, and after confirming that the isolation can be removed, each person removes their own locks and tags.

Restore energy sources in sequence (e.g., open valves, close circuit breakers) and check whether the equipment can operate normally.

Record information such as the time of the LOTO operation, personnel involved, types of energy sources, and isolation measures for traceability.

If problems are found during the operation (such as damaged locks, missed identification of energy sources), provide timely feedback and improve the process.
