What combines hazard severity and mishap probability to guide safety decisions?

• A. Risk Assessment Code (RAC)
• B. Hazard Severity Index
• C. Probability Severity Index
• D. Risk Management Metric

Answer: (A)

Risk Assessment Code is the way to blend how serious a hazard could be with how likely it is to cause a mishap, giving a single risk level that guides safety actions. This pairing helps you prioritize with clarity: if both severity and probability are high, you push for immediate controls; if severity is high but the chance of happening is low, you still implement safeguards but not with the same urgency; if the chance is high but the impact would be minor, you focus on preventive measures to avoid minor incidents. The other options either look at only one factor, use nonstandard terminology, or describe a broad metric that isn’t specifically about guiding safety decisions in a combined way.
