Criteria   Risks are to be assessed in terms of their likelihood and consequences based on
           the following classifications.

             Classification                Interpretation
                                           Unacceptable.
             Extreme
                                           Add additional controls or do not proceed.
                                           May be acceptable if additional controls not practicable.
             High
                                           Senior management attention required prior to acceptance.
             Medium                        Acceptable.
             Low                           Acceptable.

                 Classification            Interpretation
             Catastrophic                  Death
             Major                         Extensive injuries
             Moderate                      Medical treatment required
             Minor                         First aid treatment, on-site with immediate release
             Insignificant                 No treatment required


             Qualitative Measures of Likelihood
                 Classification            Interpretation
             Almost certain                Is expected to occur in most circumstances
             Likely                        Will probably occur in most circumstances
             Possible                      Might occur at some time
             Unlikely                      Could occur at some time
             Rare                          May occur only in exceptional circumstances
