The three components that form the basis of risk-based response are facts, science, and circumstances. Which option identifies what is NOT included?

• A. Facts
• B. Science
• C. Context
• D. Circumstances

Answer: (C)

The risk-based response is driven by facts, science, and circumstances. Facts are the verifiable data you have about the incident—what material is involved, how much there is, the container type, and current conditions. Science is applying chemical and physical principles to interpret hazards, predict behavior, exposure potential, and outcomes based on those facts. Circumstances cover the situational factors that influence risk and decision-making—location, weather, time, proximity to people, available resources, constraints, and any regulatory requirements.

Context isn’t listed as one of the formal components in this framework. It’s a broader idea that can overlap with circumstances, but the established trio uses circumstances to describe the situational factors directly impacting the response. So the option that identifies what is not included is the one referring to context.
