Some companies have implemented energy isolation and lockout management, locking hazardous energy through energy isolation and lockout to avoid direct contact between operators and hazardous energy, and using warning signs to warn other personnel. However, since the content of energy isolation management is closely related to the on-site process equipment conditions of the device and involves hazardous energy, in training practice, it only relies on training materials and classroom lectures, lacks effective operating methods, and it is difficult for operators to acquire the ability to perform energy isolation and lockout in actual application scenarios.

[0003] At present, there have been relevant studies on energy isolation training.

[0074] Example 2

[0075] A training method using the petrochemical industry static equipment inspection and maintenance energy isolation training device described in Example 1, comprising:

[0076] S1. In the specified inspection and maintenance operation scenario, analyze the process equipment conditions, specifically the cold low-pressure separator 100 separates the three-phase medium of gas, oil and water, and outputs low-pressure gas, cold low-pressure oil and water respectively. Analyze the transmission pipelines of different characteristic media respectively and prepare energy isolation schemes.

[0077] S2. Select the isolation point on the process flow chart and choose the appropriate process isolation method to ensure that during the inspection and maintenance of the cold low-pressure separator 100 equipment body, the material media of each feed and discharge pipeline are effectively isolated to ensure the safety of the operators.

[0078] S3. Energy isolation and lockout and tagout operations are performed on the selected isolation points. The process isolation mode options are preset through the training and assessment software system 200. The correct options for the process isolation modes applicable to each isolation point are marked. The process isolation mode of the isolation point is selected on the process isolation mode interactive selection module set at the isolation point of the training device, and the lockout and tagout operation is performed. If the isolation point selection is wrong, the process isolation mode selection is wrong, or the lockout and tagout operation is wrong, the sound and light device alarm 203 may be triggered, and the signal is transmitted back to the training and assessment software system 200 to record the actual operation data and determine the assessment results, so as to realize the simulated operation training and assessment of the energy isolation scene of the inspection and maintenance process.

[0079] The training method specifically includes:

[0080] Under given process conditions and maintenance scenarios, in this embodiment, that is, the maintenance scenario of the cold low-pressure separator 100, the trainees complete the energy isolation operation, including selecting the isolation point, selecting the isolation method, confirming the isolation of the material medium, executing the lock-out and tag-out operations, and unlocking and de-tag-ing.

[0081] (1) In the isolation point selection step, the sources and types of hazardous materials in the equipment, system or environment in the work area should be identified, and the isolation points of the equipment, facilities and devices that need to be isolated should be defined and confirmed.

[0082] A selection confirmation operation is performed on the intelligent touch panel 202 of the selected isolation point, and the selected isolation point data is transmitted back to the training and assessment software system 200, and the system records the isolation point selection information.

[0083] (2) In the isolation method selection step, determine the process isolation method based on the material type and the characteristics of the inspection and maintenance work.

[0084] The process isolation method selection confirmation operation is performed on the smart touch panel 202 at the corresponding isolation point, and the process isolation method selection data is transmitted back to the training and assessment software system 200, and the system records the process isolation method selection information.

[0085] (3) In the blind plate plugging operation step, select a blind plate of appropriate size in the accessory area to perform the blind plate plugging operation, or adjust the blind pass state of the figure 8 blind plate.

[0086] After completion, the signal transmitting device embedded in the blind plate transmits a signal to the process isolation mode interactive selection module of the isolation point, and the data is transmitted back to the training and assessment software system 200, which records the blind plate plugging operation step information.

[0087] (4) In the material medium isolation confirmation step, the pipelines and equipment are purged, cleaned, and tested to confirm that the hazardous materials have been cleared or isolated.

[0088] After the simulation operation of this step is completed, a confirmation operation is performed on the smart touch panel 202 at the corresponding isolation point, and the data is transmitted back to the training and assessment software system 200, and the system records the information of this step.

[0089] (5) When executing the lockout and tagout operation steps, select appropriate locks for lockout and tagout according to the determined isolation points and isolation methods. In scenarios involving the cooperation of production units and construction units, ensure that each isolation point is locked separately by the production unit and the construction unit, and ensure that each isolation locking point is hung with an appropriate warning sign.

[0090] If the simulated inspection and maintenance scenario involves the cooperation of the production unit and the construction unit, this mode needs to be selected in the training and assessment software system to ensure that each isolation point is locked separately by the production unit and the construction unit. The safety lock, lock and warning sign are connected to the process isolation mode interactive selection module of the isolation point through the signal transmitter, and the data is transmitted back to the training and assessment software system 200, which records the error information such as wrong lock selection, no warning sign, and failure of the production unit and the construction unit to lock separately.

[0091] (6) In the unlocking and delisting step, unlocking and delisting are performed after confirming that the equipment and system reset meet the conditions for commissioning.

[0092] The safety locks, locks and warning signs are connected to the process isolation mode interactive selection module of the isolation point through the signal transmitting device, and the data is transmitted back to the training and assessment software system 200. The system records the error message of unlocking and removing the sign without confirming the commissioning conditions.

[0093] At the isolation point where the error information is recorded, the sound and light alarm device 203 can be triggered to start, and under the premise of safety, a small amount of colored water medium leakage and air medium spraying can be used to warn the trainees of their wrong operations.

[0094] The training and assessment software system 200 is logically divided into a training mode and an assessment mode. In the training mode, each time a step is completed, the training and assessment software system 200 can verify whether the step is correct. If all are correct, the next step operation is started; in the assessment mode, all steps must be completed and submitted. The system determines whether the operation of each step is correct. If there is an error, the corresponding isolation point triggers the alarm mechanism, and the system records detailed error information and assessment results. Specific embodiment 1:

[0096] Training scenario: During inspection and maintenance of the cold low-pressure separator 100, energy isolation operation needs to be performed on the cold low-pressure separator 100.

[0097] Step 1: Determine the energy isolation point.

[0098] Trainees should analyze the process equipment conditions, identify all feed lines, discharge lines and instruments of the cold low-pressure separator 100, analyze them one by one and determine the energy isolation points.

[0099] After analysis and confirmation, the 8-shaped blind plate 3 on the feed pipeline A, the 8-shaped blind plate 2 on the feed pipeline B, the 8-shaped blind plate 1 on the feed pipeline C, the 8-shaped blind plate 17 on the feed pipeline E, the feed end flange of the second stop valve 12 on the feed pipeline D, the 8-shaped blind plate 4 on the discharge pipeline F, the 8-shaped blind plate 5 on the discharge pipeline G, the feed end flange of the stop valve 6 on the discharge pipeline J, the feed end flange of the stop valve 7 on the discharge pipeline H and the 8-shaped blind plate 8 on the discharge pipeline I were selected as isolation points.

[0100] At the selected isolation point, the isolation point selection is confirmed through the intelligent touch panel 202. The selected isolation point data is transmitted back to the training and assessment software system 200, and the system records the isolation point selection information.

[0101] Step 2: Select the isolation method.

[0102] Trainees should determine the method of process isolation based on the material type and the characteristics of the inspection and maintenance operations.

[0103] In this specific embodiment, since flammable and explosive materials are involved, it is recommended to use double partitions and blind plate insertion isolation methods at each isolation point.

[0104] The process isolation method selection confirmation operation is performed on the smart touch panel 202 at the corresponding isolation point, and the process isolation method selection data is transmitted back to the training and assessment software system 200, and the system records the process isolation method selection information.

[0105] Step 3: Blind plate blocking operation.

[0106] Trainees select blind plates of appropriate sizes in the accessory management area to plug blind plates or adjust the blind-through state of the 8-shaped blind plates. In this specific embodiment, the states of the 8-shaped blind plate 17 on the feed pipeline E, the 8-shaped blind plate 1 on the feed pipeline C, the 8-shaped blind plate 2 on the feed pipeline B, the 8-shaped blind plate 3 on the feed pipeline A, the 8-shaped blind plate 4 on the discharge pipeline F, the 8-shaped blind plate 5 on the discharge pipeline G, and the 8-shaped blind plate 8 on the discharge pipeline I should be changed from open to blind-dead, and blind plates of appropriate sizes should be installed on the feed end flange of the second stop valve 12 on the feed pipeline D, the feed end flange of the stop valve 6 on the discharge pipeline J, and the feed end flange of the stop valve 7 on the discharge pipeline H.

[0108] Step 4: Confirmation of material medium isolation.

[0109] Trainees conduct tests after purging and cleaning the pipelines and equipment to confirm that the hazardous materials have been cleared or isolated.

[0110] In this specific embodiment, the trainees purged and cleaned the cold high-fraction oil, low-fraction gas, hydrogen, softened water, cold low-fraction oil and sulfur-containing wastewater in the pipelines and equipment respectively.
