Safety Integrity Level (SIL) is a measure of the performance and reliability of safety systems designed to prevent accidents or reduce risks in industrial processes. SIL levels range from 1 to 4, with SIL 1 offering the least risk reduction and SIL 4 providing the most.
These levels indicate how effectively a system can prevent or mitigate hazardous events. The appropriate SIL is determined by assessing the risks associated with a process and identifying the level of risk reduction required to meet industry safety standards, such as IEC 61508 and IEC 61511.
Identify potential hazards and
evaluate their severity and frequency.
Assign a SIL level based on the required risk reduction, considering the
consequences and likelihood of failure.
Confirm that the system design meets the reliability and performance
standards associated with the assigned SIL level.
Aligns with IEC 61508 and IEC 61511 requirements to ensure regulatory compliance.
Identifies critical risks and provides reliable systems to mitigate those risks effectively.
Ensures safety systems perform as intended, reducing the likelihood of dangerous failures.
Balances safety improvements with resource efficiency.
As your safety partner, Storm Technical provides expert SIL and LOPA assessment services tailored to your industry:
- Conduct structured risk assessments to determine required SIL levels for
your safety systems.
- Use LOPA to evaluate scenarios with high consequences and establish
appropriate Integrity Levels (ILs).
- Verify the design and performance of safety systems to meet SIL standards.
- Recommend improvements to close gaps and optimize system reliabilit.
Assess and prioritize critical risks to ensure robust safeguards are in place.
Provide testing, maintenance, and ongoing support to maintain compliance and reliability throughout the system’s lifecycle.
