    Study Notes

    Risk Management: Domain 3

    • Hazard Identification: The initial step in risk management, focusing on identifying potential hazards.

    • Assessment: Evaluating the identified hazards, considering their severity and likelihood.

    • Management: Implementing controls and making decisions to mitigate the hazards.

    • Supervise and reevaluate: Ongoing monitoring and re-assessment of controls.

    • Assessment of hazards: Determining the severity and probability to categorize risks.

    • Implement controls: Active measures to prevent or reduce the risk.

    • Controls developed and decisions made: Creating plans to mitigate or avoid risks.

    Degree of Severity

    • Catastrophic: Death, permanent total disability, project failure, loss of critical systems, severe environmental damage.

    • Critical: Permanent partial or total disability, extensive damage to equipment or systems, significant property/environmental damage.

    • Marginal: Lost work days (injuries/illnesses), minor damage to equipment/systems or environment.

    • Negligible: Minor first aid or medical treatment, slight damage, no adverse effects on project capability.

    Hazard Probability Rating

    • Frequent: Occurs very often, regularly. Example: 1/500 exposures.

    • Likely: Occurs several times, common occurrence, example 1/1000 exposures.

    • Occasional: Occurs sporadically, not uncommon.

    • Seldom: Remotely possible, needs several failures for it to occur.

    • Unlikely: Could occur, but not often, very rare.

    Additional Topics

    • Composite Risk: The economic value of relative risk for a department, calculated by multiplying exposure dollars and risk index.

    • Final Ranking: Ranking departments from highest to lowest, prioritized by composite risk.

    • Types of Controls: Educational (knowledge/skills based), physical (barriers/guards), and avoidance (preventing exposure).

    • System Safety: Fail-safe passive (equipment stops), active (emergency lights), and operational (safest for people) factors.

    • Risk Management: The process of identifying, assessing, minimizing, and monitoring risks, with goals of injury/loss reduction.

    • Risk: The chance or probability of an injury, loss, or hazard, or potential hazard occurring.

    • Risk Assessment: Evaluating risks associated with identified hazards to make decisions and implement controls.

    • Hazard: A condition with the potential to cause injury, illness, or death, or damage to equipment or property.

    • Hazard Identification: The process of pinpointing hazards within a work area or task related to a specific job.

    • Probability: The likelihood that an event will occur.

    • Severity: The degree of undesired consequences of an event.

    • Risk Management Process: Hazard identification, hazard assessment, development of controls, decision-making, implementation, and supervision/evaluation.

    • Risk Exposure: Total estimated monetary value at risk due to a hazard.

    • Poka Yoke: Mistake-proofing methods to prevent errors.

    • Risk Analysis: Determining Risk associated with an element of work.

    • Risk Communication: Communicating risk information.

    • Dynamic Risk Assessment: An ongoing process of risk identification, assessment, mitigation, and monitoring, usually applied to changing operational scenarios.

    • Formal Hazard Analysis: Inductive (bottom-up, observation-based), deductive (top-down, theory-based).

    • ETA (Event Tree Analysis): An inductive technique to analyze possible outcomes from a particular risk.

    • FMEA (Failure Mode and Effects Analysis): An inductive technique for identifying critical single point of failures in a system or process.

    • Reliability: The ability of a system, component, or process to perform its intended functions over a period of time.

    • Probability of Failure: The likelihood that a particular failure will occur.

    • Hypothesis Testing: A statistical method to determine if observed data supports a specific assumption.

    • Type I and Type II Errors: Errors in hypothesis testing (rejecting a true null hypothesis or failing to reject a false null hypothesis, resp.).

    • Skinner's Behavioralism: A theory of behavior that suggests consequences influence behavior.

    • Organizational Behavior: Application of behavioral analysis to organizational performance.
