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.

Famous quotes containing the words safety, integrity and/or level:
“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
“A little integrity is better than any career.”
—Ralph Waldo Emerson (1803–1882)
“There are old heads in the world who cannot help me by their example or advice to live worthily and satisfactorily to myself; but I believe that it is in my power to elevate myself this very hour above the common level of my life.”
—Henry David Thoreau (1817–1862)
