Likelihood /

Description

Considering the presence and magnitude of the hazard and the exposure to that hazard (number of people and frequency of the tasks exposing those people), as also the status of existing controls...
5
Almost Certain / The unwanted event is almost certain to happen within the LOM (Life of Mine). In the case of repetitive/ frequent tasks the unwanted event has or will occur in order of one or more times per year. In terms of major events, as also in the case of long term health, environmental or social impacts, it may happen only once in the LOM.
4
Likely / There is a high probability that the unwanted event will occur within the LOM. In the case of repetitive/ frequent tasks the unwanted event has occurred or is likely to occur in order of less than once per year. In terms of major events, as also in the case of long term health, environmental or social impacts, it might happen once in the LOM.
3
Possible / It is possible that the unwanted event can occur within the LOM. In the case of repetitive/ frequent tasks the unwanted event has occurred or is likely to occur in order of once every 5-10 years. In terms of major events, as also in the case of long term health, environmental or social impacts, it may possibly happen once in the LOM.
2
Unlikely / There is a low probability for the unwanted event to occur within the LOM. In the case of repetitive/ frequent tasks the unwanted event has occurred sometime or is likely to occur not more than once every 10-20 years. In terms of major events, as also in the case of long term health, environmental or social impacts, there is a low probability for the event to happen in the LOM.
1
Rare / There is a very low probability for the unwanted event to occur within the LOM. In the case of repetitive/ frequent tasks there are no records of the event occurring or it is highly unlikely that it will occur within the next 20 years. In terms of major events, as also in the case of long term health, environmental or social impacts, there is a very low probability for the event to ever happen.

Generic Energy Hazard Definitions

Hazard / Aspect / Definition

Gravitational (Objects) / Potential for harm by exposure to falling, unexpected movement due to uncontrolled gravitational forces
Gravitational (People) / Potential for harm to people caused by their being subject to falling, unexpected movement or in any other way resulting from their being exposed to uncontrolled gravitational forces (incl. slips, trips, falls)
Land / Potential harm on the naturally occurring environment due to the use or management of land resulting from pollution, clearance or any other degradation
Lighting / Potential for harm resulting from excess light or inadequate lighting in the workplace

Psychological / Potential for harm associated with stressors from situations, conditions or events that could create negative emotional, cognitive or behavioural outcomes
Radiation / Potential for harm by exposure to radiation waves whether natural or manufactured sources (characterized as either ionizing or non-ionizing sources)
Social/ Cultural / Potential for positive or negative impacts resulting from interaction of business' activities with social or cultural expectations includes social license to operate
Thermal / Potential for harm by exposure to or variations in temperature (hot or cold) but excludes anything that is on fire which has a separate category
