Hazard Analysis Flashcards

A HAZOP study uses guide words applied to process parameters to identify deviations. Which guide word indicates that a parameter is completely absent?

Answer: No / None

'No' or 'None' is the HAZOP guide word indicating a complete absence of the intended parameter, such as no flow when flow is required.

Which MIL-STD standard provides the primary DoD requirements for system safety and hazard analysis in defense test programs?

Answer: MIL-STD-882

MIL-STD-882 (System Safety) is the primary Department of Defense standard that establishes requirements for hazard identification, risk assessment, and risk management in defense programs.

When classifying hazard severity, a condition that may cause severe injury, major occupational illness, or major property damage is typically categorized as:

Answer: Critical

Under MIL-STD-882, 'Critical' severity describes conditions that may cause severe injury, major illness, or major property/system damage short of complete loss.

An Operational Hazard Analysis (OHA) is primarily focused on:

Answer: Hazards that arise from personnel tasks, procedures, and the operational environment

An OHA evaluates hazards associated with human tasks, operational procedures, and the environment in which the system is used or tested.

In a test range safety context, a 'destruct zone' is defined as:

Answer: The geographic area where debris is expected to fall if a flight termination system is activated

A destruct zone (or impact zone) is the calculated area where debris would be expected to land following activation of a flight termination system, used to ensure public safety.

Which of the following best describes the purpose of a Subsystem Hazard Analysis (SSHA)?

Answer: To identify hazards arising within a single subsystem and its interfaces with other subsystems

An SSHA focuses on hazards within a specific subsystem and examines how that subsystem's interfaces with other subsystems may introduce or amplify hazards.

During a test readiness review (TRR), the hazard analysis products are reviewed to ensure:

Answer: Identified hazards have been adequately controlled and residual risks have been formally accepted

At a TRR, hazard analysis products are reviewed to confirm that identified hazards have appropriate controls in place and that remaining residual risks have been formally reviewed and accepted by the authorizing official.
