of hazards must foster creative thinking about possible hazards that have not previously been
experienced. Assumptions made in the Formal Safety Assessment must be documented,
reasonably justified, reviewed by appropriate personnel, properly referenced, with limitations
known and tracked to identify any change(s). The FSA process should also include identification
of risks and appropriate safeguards relevant to each hazard.
The assessment of risk from scenarios must consider the effectiveness, availability and viability of
control measures, including the potential for escalation of the scenario, detailing the range of
additional risk control measures considered and the reasons for implementation or rejection of
each and the risk due to evacuation, escape and rescue (EER).
Note: It is expected that the proponent of the Safety Case adopts FSA models, approaches and
methodologies that are descriptive (such as Bow-Tie etc.) to easily facilitate workforce
understanding of Hazard management and their own role in it.
4.4.1 Major Accident Hazards (MAHs)
The proponent shall demonstrate, with regards to Major Accident Hazards (MAHs), that all
reasonably practicable controls have been identified to ensure that risk is “as low as reasonably
practicable” (ALARP). MAHs are threats or hazards which, if released could potentially result in:
i.
Fatalities or serious injuries to personnel;
ii.
Fatalities or serious injuries to any member of the public;
iii.
Major property and asset damage (fire/explosion, etc.);
iv.
Considerable impact to the environment;
v.
Impact to community(s) (displaced, inconvenienced, etc.),
vi.
Damage to business reputation, and;
vii.
Other undesired consequences as may be determined by the Proponents and Stakeholders.
4.4.2 Formal Safety Assessment (FSA) Team Composition
In order to maximise opportunities for identification, control of hazards and ensure adequate
technical submissions, operational experience and expert opinions are incorporated in the risk
