4.2. Minimize out of control probability of the identified status hazards
Control criteria and control measures should be setup to minimize out of control probability of the identified status hazards. If the identified status hazards meet the control criteria, they are called controlled status hazards which do not have the potential to trigger accidents. Furthermore, to ensure that the identified status hazards are under the control of different responsibility subjects and are prevented from evolving into the uncontrolled status hazards, the directly responsible individual, direct manager and supervisor of the identified status hazards and their corresponding control measures should be clear and definite. As an example, the above method was applied to the identified status hazard, namely shearer picks are seriously worn or lost, as shown in the Table 2.
