Standards and safety in MRO: Calculation of SIL levels: selection of safe components for safe operation of machines

Introduction: Why standardization matters for the functioning of production

The safety of the production process is the basis of the efficiency, quality and durability of the equipment. In Ukraine, where the industrial production base plays a key role in economic development, compliance with safety standards and technical requirements is mandatory. In particular, the calculation of SIL (Safety Integrity Level) is a critical element to ensure the safe operation of machines and equipment.

Scope: who must comply with which components, which industries

SIL certification is required for all components responsible for the safety of production equipment, including valves, valves, sensors, solenoids, level sensors and actuators. These elements are used in industries such as metallurgy, chemical industry, energy and transport.

Main requirements: table of main duties and deadlines

Below is a table that shows the basic requirements for components used in security systems.

Impact on MRO operations: how support, procurement, documentation have changed

Compliance with SIL standards causes changes in the work of MRO services. In particular, there is a need to use certified components that meet SIL requirements. This affects the selection, procurement, installation and monitoring of components. Careful documentation is also required to ensure transparency and compliance.

Component Requirements: Which parts must meet specific certifications

Components used in safety systems must have certifications such as CE, UkrSEPRO, and also comply with standards such as EN 13445-2, IEC 60947-5-1 and EN 60751. For example, valves must comply with EN 13445-2 and level sensors with EN 60751.

Conformity Check: A Practical Check for Maintenance Managers

Below is a checklist that a maintenance manager can use to ensure compliance with SIL standards.

1. Check the certification of each component for compliance with standards.
2. Ensure that all components are used in conditions that meet their specifications.
3. Perform periodic inspection and maintenance of components in accordance with SIL requirements.
4. Maintain a compliance report to ensure transparency.
5. Use only certified spare parts that meet the standards.
6. Be sure to check whether the spare parts correspond to the available documentation.
7. Establish quality control and compliance processes.
8. It is mandatory to keep a maintenance log.
9. Conduct periodic audits to ensure compliance with standards.
10. Use modern methods of risk analysis and identification.
11. Use components that meet SIL requirements.
12. Check whether the spare parts meet the requirements for operating temperature and pressure.
13. Use components that meet the requirements for electrical characteristics.
14. Use components that meet the requirements for mechanical stability.
15. Use components that meet the requirements for operational durability.
16. Use components that meet energy efficiency requirements.
17. Use components that meet the requirements for environmental safety.
18. Use components that meet the requirements for strength.
19. Use components that meet reliability requirements.
20. Use components that meet the requirements for stability.

Common Compliance Issues: What Auditors Find

Auditors often find problems related to the use of improperly certified components, lack of documentation, or faulty quality control systems. These problems can lead to higher risk, higher costs and equipment malfunctions.

Sanctions and liability: consequences of non-compliance

Failure to meet SIL standards can result in fines, loss of insurance, liability to third parties, and loss of customer trust. In the event of an accident or accident, the company may suffer large financial losses and loss of reputation.
