What is Engineered Safety?
Practice/tool/ technique Used for....
Safety in Design / PHA
(Also 'CHAIR')
Systems / Process Safety
HAZOP studies per AS IEC 61882
SWIFT
FMEA per AS IEC 60812
(FMECA, FMEDA, process FMEA)
QRA/ PRA & Bow-tie analysis;
Event tree & Fault tree analyses
LOPA (Layers of Protection
Analysis)
Functional Safety per
AS IEC 61508/61511
Major Hazard Facilities
What will be the 'human-to-asset', environment-to-asset, and asset-
to-asset interfaces, and can we make them safer?
Understand top-level concepts of operations & functional reqt's,
identify the hazards and then the safety functions to control them
Analysis of what happens when design are operated outside its
design intent
Systematic what-if technique. Good for operator interactions with /
into a system (less formal / faster than HAZOP)
What if a component fails whilst operating within design intent?
Analysis of predicted, random failure rates of new designs / mod's
Typically: incident causation and consequence analysis.
Something has gone wrong...what next? (Actual or postulated)
What diverse means of achieving safe states dare there, in case one
fails?
Justification of electrical, electronic, programmable system
performance. "The safety of functions."
Legislation supported by guides from Safe Work Australia
(Good model of systems safety). Requires a SAFETY CASE
