Functional Safety Assessments (FSA)
Functional Safety Assessments (FSA) are a part of the safety lifecycle of a process that ensures the system meets the specified level of safety, typically performed by a senior engineer. The goal of an FSA is to determine how confident you are that our functional safety system will consistently achieve the risk reduction that's required. Performing an FSA is a mandatory requirement of many international standards that govern functional safety.
An FSA is carried out in five (5) stages throughout the SIS lifecycle:
- Stage 1: After the hazard and risk assessment has been carried out, the required protection layers have been identified and the safety requirement specification has been developed.
- Stage 2: After the safety instrumented system has been designed.
- Stage 3: After the installation, pre-commissioning and final validation of the safety instrumented system has
been completed and operation and maintenance procedures have been developed.
- Stage 4: After gaining experience in operating and maintenance.
- Stage 5: After modification and prior to decommissioning of a safety instrumented system.
aeSolutions’ experienced professionals can help you decide when conducting each FSA stage is appropriate for your facility, and then can help you plan and execute it.
