In the adjacent table, the
consequences, or ‘loss outcomes’ and
their related likelihood assist in accurate-
ly determining the risk ranking attribut-
able to each loss event. For example, a
consequence labelled as ‘Moderate with
a likelihood determined to be ‘Likely’,
yields an effective risk ranking of 17.
The table exhibits a risk ranking,
ranging from 1 to 25, relevant to each set
of probabilities and consequences. A
ranking of 25 constitutes a highly likely,
and thus very serious, event.
Consequently, a ranking of 1 signifies the
lowest possible degree of risk, meaning
that particular event is very unlikely to
occur.
Specific controls must be taken in order
to mitigate risk, and where possible,
eliminate it completely.

One’s level of risk is defined as the combination of the likelihood of a specific and unwanted event occurring,
coupled with the potential consequences that will be experienced should this event occur.
