Emergency Shutdown Systems (ESD):
FCM can provide ESD systems that are crucial for halting process activities during emergencies to prevent crises from escalating. They isolate hazards, such as leaks or fires, and protect against equipment damage and environmental harm. ESD systems are integrated with other safety systems, such as the Basic Process Control System (BPCS), to ensure a coordinated response to hazardous events.
The design of ESD systems involves a comprehensive cause and effect analysis to minimize the impact of shutdowns and ensure reliable operation under safe conditions3. They are also used to prioritize operations during emergencies using decision-making frameworks like the Interval-valued Intuitionistic Fuzzy Analytical Hierarchy Process (IVIFAHP).
Fire and Gas Systems (F&G):
F&G systems are designed to detect and respond to fire and gas hazards. They play a mitigation role by alerting personnel, removing ignition sources, and shutting down processes to prevent escalation. These systems are often integrated with ESD systems to provide a comprehensive safety response.
