The Emergency System Survivability Assessment (ESSA) evaluates the ability of
critical safety systems to withstand Major Accident Hazards (MAHs) and
continue functioning effectively during emergencies. This proactive approach
ensures the resilience of emergency systems such as alarms, fire protection, and
evacuation aids, minimizing risks and safeguarding personnel and assets during
incidents like fires, explosions, or structural failures.
Importance of ESSA
1.Ensures System Reliability
Confirms that critical systems can perform their intended functions during emergencies.
2. Reduces Risks
Identifies vulnerabilities and recommends improvements to mitigate potential hazards.
3. Supports Compliance
Meets industry safety standards and regulatory requirements.
4. Enhances Emergency Preparedness
Improves the resilience of systems to respond effectively during crises.
Main Components of ESSA
1. Fire and Gas (F&G) Detection System
Alerts personnel to hazardous conditions.
2. Emergency Shutdown (ESD) and Blowdown Systems
Safely isolate and depressurize equipment to prevent escalation.
3. Emergency Communication System
Maintains reliable communication during crises.
4. Emergency Power and Lighting Systems
Provides critical power and visibility.
5. Heating, Ventilation, and Air Conditioning (HVAC)
Ensures safe conditions in muster areas or control rooms.
6. Active Fire Protection (AFP) Systems
Suppresses fires to protect personnel and equipment.
7.Navigational Aids
Ensures safety during evacuation.
Steps in ESSA
1
System Review
Assess safety systems for vulnerabilities under specific MAH scenarios.
2
Fail-Safe Mechanism Evaluation
Ensure systems automatically shift to a safe
mode and maintain functionality during emergencies.
3
Redundancy Analysis
Verify if backup mechanisms are sufficient to ensure
system reliability in the event of component failure.
4
Diversity Assessment
Explore alternative approaches or components to
enhance system robustness when redundancy is insufficient.
5
Survivability Testing
Conduct detailed tests to evaluate system performance
under credible MAH scenarios.
6
Impairment Criteria Assessment
Analyze factors like thermal radiation,
explosion overpressure, and smoke that could impair system functionality.
7
Propose Enhancements
Recommend measures to address weaknesses and
improve system survivability.
