This content is intended for general information. The application must be carried out by means of equipment manufacturer instructions, the risk assessment specific to the business and the energy control procedure prepared by authorized persons.
Why do we need a special choice?
Close the valve alone on the process lines does not always eliminate the risk of discharge or wrong opening of the valve. In critical tasks, blinding or physical separation may be part of a plan for lock and labelling.
Data for the product selection
The diameter of the flange, the layout of the cave, the type of blindness, line pressure, temperature and fluid hazard are defined in the engineering plan. The lock product is selected in such a way that prevents the unlawful dismantling of the blind or flange connection.
| Plan Information | Registration |
|---|---|
| Line/Team Code | The right isolation limit. |
| Current and Conditions | Cleaning and PPE |
| The Blind Class | The engineering suitability |
| The Lock/Label owner | Authority and Valeria |
Order of Application
- Confirm the line isolation plan and permission system.
- Close upstream and downstream valves.
- Empty the line controlled, clean it and verify the safe condition.
- Apply blinding or physical separation with authorized procedure.
- Close the blind point, label it and record it.
Frequent mistakes
- The only one is positive isolation.
- Relaxing the pressure
- Not to choose the blind plate class according to process conditions
- Do not transfer the isolation limit to the valley
What should be sent to match the offer or product?
The brand-model of the equipment must be sent together, general and close plan photos in a safe state, millimeter measurements, energy type, number of people to work at the same time, and the usage environment. This information reduces the risk of choosing product code according to its appearance alone.
Share your photos and sizes; let us evaluate the product, procedure, training and simulator needs together.
