In addition to the above demonstration, an Operator wishing to implement an RBI 
program must have the resources and structure to implement and sustain the program. 
This will include the continuous involvement of experienced corrosion, materials, 
inspection, safety, maintenance and process engineers/technologist in the process. The 
DPR shall be informed if an Operator intends to alter the acceptance criteria and safety 
objectives for risks in the activities, failing which the DPR may choose to invalidate the 
approval process. 
3.3.1 
Safety Objectives 
Operators implementing RBI methodology and risk assessment shall define safety 
objectives for their activities. To ensure that the planning, maintaining and enhancement 
of safety in the activities become a dynamic and forward-looking process, the Operator is 
required to express his safety objective as an ideal safety level.  The safety objectives shall 
reflect the requirement of all applicable Regulations with regards to safety of people, 
assets, the environment and cost.  
Depending on the activity, the Operator's safety objectives may be expressed as long-term 
and short-term objectives and shall be used to determine preventive safety measures 
based on knowledge obtained through a risk analysis. This shall be used for the 
enhancement of safety in the activities and shall form the basis for revision of the 
Operator’s acceptance criteria.
