Risk Assessment (definition) • Process in which information is analyzed to determine if a hazard may cause harm A ratio to measure characterize cancer risk. MOS = (NOAEL or LOAEL or BMDL)/ Dose (LADD or ADD) Want a BIG number --> 1000 or more, generally. Start studying Risk Ratio, Odds Ratio, Kaplan-Meier, Survival Analysis, Hazard Analysis. Learn vocabulary, terms, and more with flashcards, games, and other study tools. A hazard identification process such as a Preliminary Hazard Analysis (PHA) or a Hazard and Operability Study (HAZOP) should consider these abnormal events. The most commonly used standard in the UK for determining area extent and classification is BS EN 60079 part 10 1 , which has broad applicability. I. Introduction.
