A dump system, quenching system and reaction-interfering agent are all examples of:

• A. Secondary containment
• B. Primary containment
• C. Mitigative safeguards
• D. Emergency process abort system

Answer: (D)

These interventions are all aimed at interrupting a hazardous reaction in real time to prevent it from escalating. A dump system removes material or heat from the reaction zone, quickly reducing the conditions that drive the hazard. A quenching system cools the reaction mixture to suppress further reaction progress. A reaction-interfering agent slows down or stops the chemical steps that feed the hazard. Together, their purpose is to abort the process during an upset, stopping the dangerous sequence as soon as unsafe conditions are detected. That makes them emergency process abort system measures. They aren’t primarily about keeping contents contained within a vessel (primary containment) or contained by barriers around equipment (secondary containment). They’re active, rapid interventions meant to halt the process itself, which is why this option is the best fit.
