 Level          Descriptor                      Qualitative Description
 A              Almost Certain                  The event is expected to occur at least once a year
 B              Likely                          The event will probably occur on average once every 10 years
 C              Possible                        The event may occur on average once per 100 years
 D              Unlikely                        The event could occur once on average once per 1,000 years
 E              Rare                            The event could only occur once on average once per 10,000 years



The level of risk depends on the likelihood of the risk occurring, and its consequence. The risk criteria employed
for this assessment, which was drawn from the ranking criteria presented in the Safety in Design (Consult
Australia, August 2010) (p10) are shown in Table 6.
