The document discusses hazard identification (HAZID) and risk assessment processes. It mentions undertaking HAZID at all stages of a project to identify hazards and communicate them. Risk is then assessed qualitatively or quantitatively using models, with quantitative risk assessment (QRA) requiring building a model based on reliable data. Hazards and effects are recorded in a register to ensure traceability and inform determining risk levels aligned with a risk matrix. The register is then frozen to prevent costly late design changes from increasing risks.
