A functional safety assessment (FSA) is a required investigation to judge the functional safety achieved by one or more safety instrumented systems (SIS) and other protection layers. An effectively designed SIS will detect dangerous process conditions and automatically respond to bring the process to a safe state.

A successful FSA will determine compliance with IEC 61511 and whether it is implemented properly to prevent or mitigate a hazardous event or failure. At Equity, our Instrumentation, Controls, & Electrical Engineering Team offers technical support for all stages of a safety system’s lifecycle
