AAOM Handbook

Required Date: In determining the Required Date, the following need to be considered:  What is the status of the equipment or workplace?  What is the status of the process schedule?  How do the existing or changing conditions influence exposure to hazards and risks?  Is there an alternative way of operating that can provide some flexibility in the Required Date? (e.g. guarding/containment, alternate equipment/workplace, alternate time in the schedule or increased future processing rate)? Considering the above, the Required Date is:  The date by which an event that will create a safety or environmental threat is probable  The date by which a delay in the completion of a scheduled critical path activity is probable. or  Not more than an agreed service level period (e.g. 6 weeks) from the date of Work Request creation. Impact: In determining the Impact, the following need to be considered:  What potential events could occur?  What is the probability over time of an event occurring?  What are the potential consequences?  Is the threat containable?  Is the loss recoverable? Or  Not more than an agreed service level period (e.g. 6 weeks) from the date of Work Request creation. Impact: In determining the Impact, the following need to be considered:  What potential events could occur?  What is the probability over time of an event occurring?  What are the potential consequences?

 Is the threat containable?  Is the loss recoverable? Considering the above, the definitions of Impact are: High –

 Significant un-containable safety or environmental threat, or  Significant un-recoverable process throughput or quality reduction o Un-containable means that there is no practical way to contain exposure to a threat e.g. use temporary measures such as the installation of barricades, diverting spillage into sumps, drawing from or building stockpiles, subcontracting alternate suppliers for goods or services etc. o Un-recoverable means that there is no alternate equipment, schedule time, operating rate or alternate suppliers etc that will allow catch up to schedule.

Moderate –
