Risk modules¶

Exposures and hazard characterisations are compared in risk metrics. If both exposure and hazard characterisation are characterised by a single value, the risk metric (e.g. a traditional margin of exposure, hazard quotient or hazard index) can be calculated using module Single value risks. Module Risks allows for probabilistic risk calculations. In both cases a threshold can be specified to assist in interpretation. The threshold value should be chosen in relation to the assessment factors used in the hazard characterisation, e.g. a threshold MOE=100 is often used if no assessment factors have been used, but a threshold 1 would be appropriate if assessment factors have already been used to address relevant uncertainties.
