AAOM Handbook

• for which Service Work packages are likely to be independent of the Service Work packages for other elements of the Activity/Workplace/Equipment, and • that identify the likely Pareto set (the 20% of items that include 80% of the work) for Service Strategy actions on that Activity/Workplace/ Equipment, should be created as Tasks/Locations/Components of the Activity/ Workplace/Equipment. 3. Each parts assembly where the most common Service Strategy will be replacement of the assembly on the functional failure of one of its elements (the simplest may be a single item) should be created as a Part. 4. Serviceable Items associated with providing services (power/water/air supply, mine dewatering, etc.) should be included as a separate leg of the work management Location/Equipment structure where they provide services to multiple items in other legs of the structure, and then merged where they service only one item. For example, a power or water distribution system for a multi-storey building should be a separate leg of the structure from the point of supply through to the branch off to individual floors of the building. From the switch or valve that isolates each floor the serviceable items should be included in the structure for that floor. As a guide to the structure for Serviceable Items having an Asset Integrity target only, an assembly of like components that have a similar consequences in the event of an unwanted event should be identified as a Serviceable Item. For example a building may comprise; structural steel, concrete foundations/footings, roofing and cladding, each of which could be classified as Serviceable items. The components (such as columns, beams, etc.) that will likely be affected by a specified risk will be identified as objects in the risk description, e.g. corrosion of column bases. When identifying Serviceable Items, consider; • Process Flowcharts, P&IDs, General Layouts, equipment lists, etc. to identify potential Serviceable Items, • potential Integrity critical items matching any entry in the attached checklist – Appendix 1, • potential hazards from the checklist in Appendix 2, • potential hazard release mechanisms in Appendix 3, • Risk ranking from the table in Appendix 4, • safety margins, operational controls, checks and mitigation techniques in place, • the probability distribution of the occurrence of an unwanted event, and • the probability of exposure to an unwanted event once the hazard is released.

A database entry shall be created for each Serviceable Item.
