What is the main objective of a HAZOP study?
To identify deviations from design intent and assess their consequences
To calculate the cost of production losses
To review the plant design, as per codes and standards
To assess risks associated with the daily maintenance activities
What is the purpose of a LOPA study?
To determine if there are sufficient layers of protection against an accident scenario
To identify potential process & environmental hazards
To design new safety equipment
To identify Safety Critical Tasks (SCTs)
What does the term "Risk" represent in risk assessment?
The probability of an event occurring
The combination of consequences and probability of occurrence
The severity of an incident
The likelihood of human error
What is the purpose of an Independent Protection Layer (IPL) in a LOPA study?
To replace the need for safety instrumented systems
To eliminate hazards completely
To provide a reliable means of reducing risk independent of other layers
To ensure business continuity during high-risk operations
Which of the following would be classified as a "Preventive Barrier" rather than a "Mitigative Barrier"?
Fire suppression system
Gas detection alarm
Emergency venting system
Process containment system
Which of the following is NOT a characteristic of a Safety-Critical Element (SCE)?
Required to manage major accident hazards
Its failure could lead to catastrophic consequences
It is only used in financial risk assessments
It is subject to performance standards
What is a primary advantage of conducting a HAZID study at an early stage of design?
It reduces the cost of hazard mitigation measures
It eliminates all operational risks
It prevents the need for emergency response plans
It ensures that process design is optimized for maximum production efficiency
