ABSTRACT
The number of qualitative, semiquantitative, and quantitative tools available to risk assessors is growing at an increasing rate. Over four dozen distinct tools are introduced. Their utility for hazard identification, consequence assessment, likelihood assessment, risk characterization, uncertainty characterization, risk management options, and other uses are noted for each tool, making it easier to suit the tool to the task. Tools include: brainstorming. Bayesian statistics and Bayesian Networks, bow tie analysis, cause-and-affect analysis, cause-consequence analysis, checklists, cost-benefit analysis, Delphi techniques, dose-response curves, ecological risk assessment, event trees, evidence maps, expert elicitation, failure mode and effects analysis, fault trees, fragility curves, FN curves, a generic process, HACCP, HAZOP, heat map, human reliability assessment, increase or decrease risk, interviews, LOPA, Markov analysis, Monte Carlo process, MCDA, ordering techniques, preliminary hazard analysis, qualitative risk assessment models, reliability-centered maintenance, risk control effectiveness, risk indices, risk matrix, risk narrative, root-cause analysis, safety assessment, scenario analysis, scenario planning, semiquantitative risk assessment, sensitivity analysis, SWIFT, subjective probability elicitation, uncertainty decision rules, and vulnerability assessment.
