General rules for energy isolation
1 applicable conditions for energy isolation
When entering, transforming or maintaining a certain equipment, facility or device, external energy should be cut off to avoid accidental release of energy. Such as power sources, fluid and pressure sources, mechanical drives and control systems.
2. Provisions for electrical isolation
Device source power off and locked; Such as power distribution sources for equipment, facilities and installation systems;
The signal isolation is a special form of electrical isolation, which is completed in the form of isolation and bypass.
Mechanical isolation regulations
Process isolation method
Single valve isolation
Double valve isolation and discharge method
Single valve isolation plus blind plate
Isolation of confined space entry
Pipeline disassembly isolation method
Double partition and insert blind board method
General requirements for isolation operations
To control by issuing quarantine certificates;
The isolator and the isolator shall not be the same person;
Process isolation selection diagram should be used as the basis for determining mechanical isolation method or type;
If there is any change, the feasibility of risk assessment to identify the risk and isolation;
Qualification of isolator;
On-site verification prior to quarantine;
