SIL - Safety Integrity Level of the Technical System
The Safety Integrity Level (SIL) is defined as the relative reduction in risk provided by the Safety Instrumented Function (SIF).
SIL is a measure of the power required for SIF. European safety functional standards based on IEC 61508 define four SIL, with SIL 4 having the highest safety integrity level and 1 the lowest.
SIL Analysis – SIL Identification / Classification most often follows the HAZOP study for the assessed equipment / technology.CONTACT US
OBJECTIVE / BENEFIT OF SIL ANALYSIS (SIL IDENTIFICATION / CLASSIFICATION)
- Providing SIL classification for all SIFs within the scope of work
- Proposing actions to optimize the process
- Exploring other scenarios
- Modification of the required SIL classification
THE SIL ANALYSIS IS CARRIED OUT IN THE FOLLOWING STEPS
