Document Summary
Reading 20 absent ch11 risk assessment and management (ontario focus) Risk matrix: y axis how much we know about risk. X axis how much we dread risk. High dread = most important factor in risk. Risk assessment = process of identifying hazards. Assign both magnitudes and probabilities to the adverse effect that those hazards have on people and the environment. Risk characterisation [estimated probability of the adverse effect on a given. On the hazard frequency vs magnitude of impact curve, the area under the curve is the total risk. Riskiest activity is that with greater area under the curve. The most concerning risk depends on who you are costs of e. g. bad pr, or ecological disaster for a government is bad. Greater fatalities draws greater reporting in media. Risk of death from env hazards and their cost of reduction. Table from the council on env quality (1990) are all regulated by environmental policies.
