Safety Integrity Level
The safety integrity level is determined primarily from the assessment of three factors. Higher level safety integrity levels require greater compliance in all three areas. 1) Improved reliability. 2) Failure to safety. 3) Management, systematic techniques, verification and validation. SIL refers to a single method of reducing injury (as determined through risk analysis), not an entire system, nor an individual component.
