Managing safety is moving from the isolated application of strictly technical tools to a more robust safety case approach that applies multiple assessment methodologies to demonstrate that both technical and organisational risks are managed effectively. With the growing emphasis on performance-based legislation, the safety case is not only a mechanism for achieving safety goals but has also become an important liability management tool.This second edition has been prepared in response to significant changes made to the 2004 edition of the Australian rism management Standard AS/NZS 4360 and the Victorian OH&S regulations, 2007. As a result, four major changes have been made: a commom law 'duty of care' approach is now being taken - Risk concept is moving away from 'Acceptable' to 'Not intolerable' - All references to 'Best practice' now read 'Good practice', ie something that you must legally achieve - A focus on controls, rather than risk assessment.To act effectively as both a technical and liability management tool, safety cases need to have an initial argument for the approaches selected to demonstrate effective safety management. Eight paradigms for assessing risk and three inquiry methods of "risk sign off" are described.The Victorian Chapter of Risk Engineering Society of Engineers Australia, has prepared this Guideline in accordance with Victorian legislation. However, professionals in other states should find this a useful guide to preparing a safety case.
