Functional Safety (SF)

The primary objective of Functional Safety is to eliminate non-tolerable risks present in the system in order to guarantee individual, infrastructure, and environmental safety. This is achieved through the implementation of control systems – independent of the basic process control system (BCPS) such as Safety Instrumented Systems (SIS) – that automatically return the process to a safe state should a malfunction or accident occur.

SIS consists of Safety Instrumented Functions (SIF) and Safety Integrity Level (SIL) generally put into place in a Layer of Protection Analysis (LOPA). SIFs are typically made up of sensors that detect critical conditions, as well as logic processors to determine the next step(s) and the equipment needed to carry them out. The system design must consider several crucial factors to function properly.
