CTC Hazard Analysis 2

Question 1

Which hazard analysis technique uses a top-down, deductive approach to identify combinations of events that lead to an undesired top event?

Accepted Answer

Fault Tree Analysis (FTA)

Answer

Fault Tree Analysis (FTA) is a top-down, deductive technique that uses Boolean logic to trace combinations of failures leading to a defined top-level undesired event.

Question 2

In a Hazard Analysis and Risk Assessment (HARA) for a test environment, the term 'severity' refers to:

Accepted Answer

The potential magnitude of harm if the hazardous event occurs

Answer

Severity describes the potential magnitude or seriousness of harm (injury, damage, or loss) that could result if a hazardous event actually occurs.

Question 3

A test conductor identifies that a pressure relief valve may fail to open during a high-pressure test. In FMEA terminology, this failure mode's 'detectability' rating reflects:

Accepted Answer

The ability of current controls to detect the failure before it causes harm

Answer

Detectability in FMEA rates how effectively existing controls can identify a failure mode before it reaches the end user or causes harm.

Question 4

Which document formally establishes the hazard controls, residual risks, and responsible parties for a specific test operation?

Accepted Answer

Hazard Control Plan (HCP) or Risk Mitigation Plan

Answer

A Hazard Control Plan (or Risk Mitigation Plan) formally documents identified hazards, the controls applied, residual risk levels, and who is accountable for each control.

Question 5

During a live-fire test, an unexpected misfire occurs. According to standard hazard control hierarchy, the FIRST priority action should be to:

Accepted Answer

Apply engineering controls to eliminate the hazard at the source

Answer

The hierarchy of controls places elimination/engineering controls at the top, meaning the preferred approach is to remove or control the hazard at its source before relying on administrative or PPE controls.
