There are three Average Individual Risks; 1) Average Individual Risk (exposed population) is the individual risk averaged over the population which is exposed to risk from the facility, 2) 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, and 3) 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.
