Safety Integrity Level (SIL) is an index used to specify the performance requirements for a specific Safety Instrumented Function (SIF). SIF’s generally identified during a HAZOP study require further assessment to define their reliability requirements. Benchmark facilitates SIL Classification Studies to match the provision of instrument protection against the potential consequences of any specific process or control failure and to reduce the risks associated with such a failure. Benchmark has Certified Functional Safety Engineers to conduct SIL Verification Study to confirm the design of each SIF meets the integrity requirement identified in the Safety Requirement Specification (SRS).
