Safety Integrity Levels (SIL) Study

A Safety Integrity Level (SIL) measures the relative level of risk-reduction provided by a safety function. In simple terms a SIL is a measurement of performance required for a Safety Instrumented Function. Four SIL levels are described with SIL 4 being the most dependable and SIL 1 being the least dependable. A SIL is determined based on several quantitative factors such as development process and safety life cycle management

How is a SIL study conducted?

A SIL study is conducting by the following process,

  • 1Name Loop Identification
  • 2Estimation of the Reliability of the Loops
  • 3Estimation of the Consequences of Loop Failures
  • 4Estimate SIL Level for different Loops and
  • 5Estimating the Level & Assessing the Consequence

The standards that GVS Cibatech follows in conducting the SIL study are:

  1. 1IEC 61511 – Functional Safety - Safety Instrumented Systems for the Process Industry Sector

  3. 3ANSI/ISA-S84.01 – Application of Safety Instrumented Systems for the process Industries.

We will also use our past experience as well as a desk review of the results of HAZOP & HSE studies.

A SIL study will indicate if additional measures are necessary to meet the stipulated level of safety or any upgradation is necessary.
