Different Key Systems for your choice:
Perform the isolation
Production and maintenance staff are also required to follow cleanup procedures, PPE specifications for personal protective equipment, and hangtag locking procedures when implementing an energy isolation plan.
Transfer and empty the residual chemicals in the process system in strict accordance with the cleaning procedures; At the same time, steam or clean or purge the process pipeline according to the process characteristics to ensure that the residual chemicals are cleaned out of the pipeline in the operating area as far as possible.
After the process system is cleaned up, the process system needs to be tested to ensure that the amount of residual chemicals is lower than the minimum explosion limit and toxicity, etc., to confirm and verify the effectiveness of the cleaning.
For valves, rotating equipment and energy sources in the energy isolation plan, Lockout tagout shall be performed after on-site operation according to the energy isolation plan to ensure that they are not misoperated by other personnel and the integrity of the energy isolation plan during maintenance or project.
The energy isolation red card must be hung on the valve or equipment at the energy isolation point to inform and warn others not to operate. The red card indicates the operator and date, isolation point equipment status, energy source type, etc.
Similarly, the valve at the energy isolation point should be locked so that others cannot operate the valve device. The key of the lock needs to be put into the energy isolation lock box. After the energy isolation is completed, the lock box must be locked by the production personnel, who will save the key.
After confirming the energy isolation plan and installing the energy isolation blind plate on the site, the representatives of the field maintenance team need to lock the energy isolation box at the same time. At this point, the on-site energy isolation plan is protected by both production and maintenance teams.
Before the on-site work, the maintenance team must also confirm and verify the energy isolation plan on site, such as confirming the status of relevant valve switch, no material discharge of shower valve, inching equipment switch and measuring voltage to confirm the isolation of electrical energy, etc., before starting the on-site work formally.
The maintenance representative cannot remove the maintenance lock on the energy lock box until the on-site maintenance work is completed and handed over to the production unit. Only then can the production personnel remove the energy isolation points on the site one by one, record and confirm them on the energy isolation schedule one by one, and restore them to the state of process pipelines and equipment before maintenance.
In summary, the energy isolation plan is a systematic method to isolate and control energy sources, from process system energy isolation assessment, cleaning plan, detection method, blind plate installation, electrical partition, Lockout tagout, to completion of energy isolation plan, to confirmation and verification of energy isolation before work.
Until the end of the maintenance work, the energy isolation point can be removed step by step and the process system can be restored to ensure that there are no omissions, so as to effectively protect the safety of repair team members, the safety of equipment and property and the integrity of the process system restored after maintenance.
Zhongcheng reminds you that in the process of inspection and maintenance, the relevant regulations of pipeline opening and Lockout tagout must be strictly implemented, and the relevant energy isolation measures should be effectively implemented before the operation, so as to ensure the safety of the operation.
