Functional Safety Analysis is an approach that assesses all the system functions to determine the hazards associated with what the system does. The purpose of Functional Safety Analysis is to identify hazards associated with both the correct and incorrect operation and non-operation of the system, lower level functions and human functions.

Failure modes and effects analysis (FMEA) is a reliability evaluation technique to determine the effect of system and equipment failures. This qualitative technique helps identify failure potential in a design or process i.e. to foresee failure before it actually happens.
A FMECA is an analytical quantitative technique which ranks failure modes according to their probability and consequences.

Event trees are graphical representations of binary logic models which identify and can quantify possible consequences resulting from an initiating event (e.g. component failure). The event tree provides systematic coverage of the time sequence for the event’s propagation.

This guidance paper covers both the technique of Cause Consequence Diagrams and three analyses which may be used subsequently, where quantitative ALARP justification is necessary. Both Def Stan 00-56 and the MOD’s POSMS manual give guidance on when quantitative ALARP justification may be required, and this is likely to be for hazards not addressed by the application of good practice and those with the highest levels of Risk.

The HAZOP procedure is a systematic methodology carried out by a multi-disciplinary team with substantial experience of the system or design. Detailed analysis of predetermined deviations from the design intent, and the associated causes, consequences, safeguards and recommendations are recorded.
