To prevent errors of omission and commission in following such a safe operating procedure. The system provides protection, should there be a malfunction of fuel firing equipment and associated air systems. The safety features of the system are designed for protection in most common emergency situations. Basic Functions of FSSS:- Prevent any fuel firing unless a satisfactory furnace purge sequence has first been completed. Prevent start-up of individual fuel firing equipment unless certain permissive interlocks have first been satisfied. Monitor and control the proper component sequence (manual or automatic) during start-up and shutdown of fuel firing equipment. Make continued operation of fuel firing equipment subject to certain safety interlocks remaining satisfied. Provide components
