Introduction: why standards affect production efficiency
Modern industrial enterprises in Ukraine depend on reliable equipment operation, which requires strict compliance with safety standards. Standards such as IEC 61508, IEC 61511, as well as DSTU 4466:2016, provide the basis for assessing the level of safety of automation and control systems. They define requirements for components used in safe systems, as well as establish rules for selecting elements with appropriate SIL ratings.
Application Range and Requirements
SIL (Safety Integrity Level) certification is required for systems ensuring the safety of production processes. This includes automated control systems, sensors, actuators, controllers and other components that affect the safety of personnel and equipment. The requirements are established in standards IEC 61508, IEC 61511 and DSTU 4466:2016, which define the safety levels required for different types of technological processes.
Main requirements and terms
| Certification | Average Safety Level (SIL) | Highest level of safety (SIL) | Term of validity |
|---|---|---|---|
| IEC 61508 | 1–4 | 4 | 2025 |
| IEC 61511 | 1–3 | 3 | 2025 |
| DSTU 4466:2016 | 1–4 | 4 | 2025 |
Impact on MRO operations
Compliance with safety standards significantly affects the work of MRO (Maintenance, Repair, and Operations). Technicians and engineers must ensure the use of components that meet established SIL ratings, which requires changes in procurement, installation, and documentation processes. They must conduct inventory of equipment, perform periodic inspections, and keep documentation with certification.
Requirements for components
For safe equipment systems, components with appropriate certificates are required. For example, actuating mechanisms, sensors, controllers and modular systems must have certificates complying with standards IEC 61511 or DSTU 4466:2016. Each component must be appropriately defined according to the safety level established in the technical specifications.
Compliance Check
For effective compliance with safety standards, masters must perform the following actions:
- Determine the SIL rating for each component.
- Check valid certificates and manufacturing dates.
- Keep the certification documentation in an accessible location.
- Conduct regular checks for compliance with standards.
- Update the list of components with the corresponding certificates.
- Perform the corresponding tests and testing.
- Maintain a log of duty performance and changes.
- Perform audits to detect incorrect cases.
- Report on compliance with requirements.
- Train personnel on the rules of using certified components.
- Set up component restoration processes.
- Perform the corresponding conformity tests.
- Keep the change history in the documentation.
- Carry out periodic inspections of equipment.
- Monitor the fulfillment of requirements.
Incorrect correspondence
Auditors most often identify the following problems:
- Use of components without the appropriate certificates.
- Non-compliance with the safety level (SIL) requirements.
- Errors in the documentation or its absence.
- Errors in the execution of tests.
- Non-compliance with requirements to standards.
- Non-conformance to specifications.
- Errors in performing audits.
- Document storage errors.
- Errors in implementation of changes.
- Errors in the execution of tests.
Sanctions and Liability
Incorrect execution of safety requirements may lead to serious consequences:
- Financial penalties established by Ukrainian legislation.
- Increased risk of accidents.
- Liability for negligent damage.
- Change of terms of compliance.
- Failure to obtain production permits.
- Export license denied.
- Loss of trust in the company.
- Increase in insurance cost.
- Increase in the cost of equipment restoration.
- Increase in liability costs.
