There are three Average Individual Risks.
- A. Average Individual Risk (exposed population) is the individual risk averaged over the population which is exposed to risk from the facility.
- B. Average Individual Risk (total population) is the individual risk averaged over a predetermined population, without regard to whether or not all people in that population are actually exposed to the risk.
- C. Average Individual Risk (Exposed hours/worked hours). The individual risk for an activity may be calculated for the duration of the activity or may be averaged over the working day.
