Lockout tagout isolation

Lockout tagout isolation

According to the identified hazardous energy and materials and the possible hazards, the isolation plan (such as HSE operation plan) shall be prepared. The isolation plan shall specify the isolation method, isolation points and the list of locking points.

According to the dangerous energy and material properties and isolation mode to choose matching disconnect, isolation device. The selection of isolation devices should consider the following:
– Special hazardous energy isolation device to meet special needs;
– Technical requirements for installing locking devices;
– Buttons, selector switches and other control circuit devices shall not be used as hazardous energy isolation devices;

Control valves and solenoid valves cannot be used as fluid isolation devices alone; The control valve specially designed for dangerous energy and material isolation device can be implemented according to the requirements of “Pipeline disconnection and blind plate isolation Management Standard”;

Appropriate methods shall be used to remove and completely isolate hazardous energy or materials and be identified. In the case that the test cannot be fully confirmed, test confirmation should be carried out;

– Some method should be used to prevent re-accumulation of energy due to system design, configuration or installation (such as long cables with high capacity);
When the system or equipment contains stored energy (such as springs, flywheels, gravity effects or capacitors), the stored energy should be released or blocked by the use of components;
- In complex or high energy power systems, protective grounding should be considered;
