Safety module uses common libraries with FMECA module.

 

Libraries which are relevant for the Safety module are:

Define your product mission (or life cycle) phases on the Phases tab of the library screen. Define duration for each phase. Put the total mission (e.g. "whole flight") phase to be the first phase in the list.

Classification of End Effect Severities from the point of view of Safety (each EE has two severities - FMECA Severity and Safety Severity; in the Safety module we need Safety Seevrity).

On Safety Severities page you may also set objective maximal probability of failure per average mission hour for each severity level (for SSA/AFO).

List of failure effects / hazard effects. Each effect should have Safety Severity defined for each phase (switch phases using the drop-down list above the End Effects list). You may set two objective probabilities (according to Safety Requirements and according to design requirements) for each EE and each phase separately. End Effects may be added later while working with failure conditions data grid.
