Risk Management Domain 3 Quiz

A method for identifying errors and unsafe conditions leading to potential and actual accidents using a stratified random sample of participants and observers.

A prototype that looks like the final product but doesn't function.

A prototype that functions but doesn't visually resemble the final product.

The observation of outcomes in existing groups, analyzing relationships between exposures and outcomes.

A contract protecting one party from risks and liabilities created by the other party.

A control that prevents contact or exposure with a hazard. It's about proactive action by supervisors and managers.

This control utilizes barriers, guards, or signs to warn employees of potential hazards.

This control is based on the knowledge and skills of those performing a task. It involves training to ensure consistent performance.

A concept describing how work expands to fill the available time. This means being efficient is key.

A principle that suggests 20% of employees are responsible for 80% of the work (or issues).

Any mechanism in a process designed to prevent or detect errors by humans. Think of it like an error-proofing system.

A standard that helps organizations establish safety management systems to improve employee safety and reduce risks.

A type of risk assessment that is frequently used in dynamic environments. It involves making assessments and adjustments in real-time based on changing conditions, such as those encountered by emergency responders, tradespeople, care workers, retail staff, and security personnel.

An approach to hazard analysis that starts with specific events, observations, or experiences and then draws general conclusions about the causes and potential consequences.

An approach to hazard analysis that starts with a general hypothesis, principle, or theory and then uses logical reasoning to derive specific conclusions or predictions.

A model that describes communication as a process involving a source, a message, a channel, and a receiver.

A cost that is easily identifiable and measured, such as the purchase of equipment, payment of salaries, or maintenance expenses.

A cost that is not immediately apparent but can have significant long-term impacts, such as lost productivity, reputational damage, or environmental consequences.

The process of identifying, assessing, and controlling risks to ensure the safety and well-being of individuals and organizations.

The theory that individuals naturally seek a certain level of risk and will actively adjust their behavior to maintain their desired risk exposure.

A measure of the availability of a system or asset to perform its intended function when needed.

A failure occurs when a system, component, or part deviates from its intended design parameters.

A single point of failure is a single piece of hardware whose failure could lead to a major accident, loss of life, or mission failure.

An operating and support hazard analysis is a process used to identify dangers and propose safety solutions during various stages of a product's intended use.

A system hazard analysis aims to identify and control potential hazards within a system by examining its components and their relationships.

Common cause failure analysis looks for failures that can affect multiple independent safeguards, caused by a single event or shared factor.

Sneak circuit analysis focuses on identifying unintentional energy pathways that can lead to wrong functions, block desired functions, or affect timing.

Failure Mode and Effects Analysis (FMEA) is a bottom-up method that analyzes potential failures and their consequences, starting from known causes.

Fault Tree Analysis (FTA) is a top-down method that analyzes possible causes for a known failure, starting from the undesirable event.

Preliminary hazard analysis is an initial assessment of risks that helps make informed decisions about design and manufacturing.

FMEA is a powerful tool for analyzing a single failure or a single unit failure, often used with FTA to comprehensively evaluate a product's safety.

A method used to assess the reliability of a system by considering the impact of adding various controls, starting with a 'primitive' or unprotected system and systematically evaluating the effect of each control.

The reliability is calculated by multiplying the reliabilities of all components in series. For example, if a system has 100 components in series, each with a reliability of 0.99, the overall system reliability is 0.366 (0.99 raised to the power of 100).

A tool used to analyze and control human errors by identifying specific behaviors associated with tasks and assigning error rates. It involves six steps: selecting an event, identifying tasks, separating behaviors, assigning error rates, analyzing errors, and developing controls.

A statistical measure used to determine the significance of the difference between observed frequencies and expected frequencies in a contingency table. For example, a chi-square statistic of 0.01 indicates a statistically significant result with a 1% probability of error.

A structured method for analyzing the potential consequences of an event by exploring different responses to challenges. It involves constructing a tree-like diagram that shows the branching of various possible outcomes.

Errors that occur when the null hypothesis is true but is rejected. It is a false positive result.

Errors that occur when the null hypothesis is false but is accepted. It is a false negative result.

A hypothesis test is a statistical method used to determine whether there is enough evidence to reject the null hypothesis. This hypothesis could be that there is no statistically significant difference between two groups.

A technique used to formally document and provide feedback on safety analyses performed on changes made throughout the product life cycle. It ensures that changes are properly evaluated for potential safety implications.

A graphical representation that depicts the relationship between component failure and exposure time. It shows that failure rates are higher during the initial burn-in period, then decrease during the useful life period, and finally increase again during the wear-out period.
