Total Risk is defined as which of the following?

Total Risk is defined as which of the following?

• A. The sum of identified and unidentified risks
• B. The likelihood of a single hazard occurring
• C. The severity of the most significant hazard
• D. The average risk across all hazards

Answer: (A)

Total Risk means the overall exposure to danger in a system, accounting for both hazards you know about and hazards you haven’t yet identified. It’s the sum of identified risks and unidentified risks, not just the chance or impact of a single hazard. This broader view is essential because even smaller, overlooked hazards can add up to a significant overall risk when combined with known risks. If you only consider the likelihood of one hazard, you might miss the other hazards that collectively increase risk. If you focus solely on the severity of the most significant hazard, you ignore the contributions of other hazards. If you average risks across hazards, the big risk items can be diluted and the total risk underestimated. Recognizing that total risk includes unknowns helps guide effective mitigations and allocation of resources to reduce overall safety risk.
