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:
“For hours, in fall days, I watched the ducks cunningly tack and veer and hold the middle of the pond, far from the sportsman;... but what beside safety they got by sailing in the middle of Walden I do not know, unless they love its water for the same reason that I do.”
—Henry David Thoreau (1817–1862)
“I condemn Christianity. I raise against the Christian church the most terrible accusation that any accuser has ever uttered. It is to me the ultimate conceivable corruption. It has possessed the will to the final corruption that is even possible. The Christian church has left nothing untouched by its depravity: it has turned every value into a disvalue, every truth into a falsehood, every integrity into a vileness of the soul.”
—Friedrich Nietzsche (1844–1900)
“The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy.”
—Steven Weinberg (b. 1933)
