"Three steps" - planning for maintenance energy isolation in chemical plants

planning

After cleaning the process pipelines and equipment, the personnel in the jurisdiction need to compile the energy isolation plan and isolation blind plate diagram according to the content and work scope of the operation area. The energy isolation plan mainly includes work content and scope, approval process, first isolation point, second isolation point, first and second isolation point approval and change approval management. The first isolation point is mainly to close or open the valve on the process pipeline according to requirements and empty the residual chemical materials in the process pipeline and equipment; At the same time, physically disconnect the power switch of the electrical equipment in the Control cabinet of the Motor Control Center MCC (Motor Control Center MCC) to ensure that the electrical energy is completely removed.

The primary isolation point is to prepare for the installation of secondary isolation point devices. The secondary isolation point is a necessary and sufficient supplement to the primary isolation point. For high risk of chemical process piping, equipment disconnected operation, hot work, in limited space or involve serious dangerous chemicals (including flammable, explosive, toxic, reactivity, high pressure or high temperature and other chemicals) related to the maintenance work, in principle, must want to have a second isolation protection, such as installing a blind plate as a separation point, just rely on the valve and electrical switch for energy isolation is not reliable. Such as valve internal leakage, electrical switch short circuit, etc
