HIRA

What does the acronym ALARP stand for?

• As Low As Reasonably Possible

• As Low As Reasonably Practicable

• As Low As Risk Permits

• As Low As Risk Predicts

What is the primary purpose of a HAZID study?

• To identify potential hazards and their consequences

• To calculate the financial impact of risks

• To design new equipment

• To monitor operational performance

Which of the following is a key output of a Bowtie study?

• Financial Risk Assessment

• Safety Critical Equipment (SCE) list

• List of Potential Hazards

• Safety Integrity Level (SIL)

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
