the assumptions and outputs of the Formal Safety Assessment (FSA). Proper references should
be made to all standards, guidelines and regulations being applied in the design, construction,
installation, modification, operation and decommissioning of the facility.
4.4 Formal Safety Assessment
The Formal Safety Assessment (FSA) section explains all the studies that were conducted to
identify the hazards and risks highlighted during the design phase as well as those associated with
the operation of the facility and how the identified hazards and risks are eliminated, reduced, or
otherwise mitigated to “as low as reasonably practicable” (ALARP). The purpose is to
demonstrate that all reasonably practicable controls are in place to eliminate and reduce the risk
from identified MAHs to ALARP, including all reasonably practicable steps taken to ensure the
safety of personnel, the integrity of the mitigation barriers (including under accident conditions),
and adequate facilities and measures in place to facilitate the evacuation of personnel should
there be an emergency or occurrence of a MAH.
In preparation of the FSA, the proponent is required to demonstrate that exposure of personnel
on the facility to hazards has been eliminated, controlled, minimised, through appropriate,
systematic and transparent analysis and assessment, and through implementation of the findings
of those assessments. The scope of work for identification of hazards and assessment of risks
must be consistent with the operating envelope for all activities and facilities. The FSA must
address risk to people in and around the facility due to MAHs. For a new facility or modification to
an existing facility, the Formal Safety Assessment process should start at the concept selection
stage and continue as appropriate during and throughout the design process and then into
operations. The hazard identification process must be thorough, and the level of details shall be
appropriate and commensurate with the magnitude of the hazards involved. The
results/recommendations should be systematically recorded, and appropriate quality assurance
procedures should be adopted in the document.
The processes used for identification of hazards must consider the operating history of the facility,
or similar facilities, owned by the facility operator or others. The processes used for identification
