1. Establish Risk Criteria & Scope

• Individual Risk (IR): The probability of fatality for a specific person (e.g., an operator or a member of the public).
• Societal Risk (SR): The relationship between the frequency and the number of potential fatalities (often visualized via F-N curves).
• Specific Consequences: Thermal radiation from fires, overpressure from explosions, and toxic dose from gas releases.

In this post, we break down the core components of these guidelines, explaining how to transition from qualitative guesses to quantitative data-driven safety decisions.
