SIF Assessment Status

Each SIS Analysis has an AS (Assessment Status) associated with it. This is shown on the SIF Analysis Main Screen, as well as on the General Tab.

The Assessment Status indicator turns green (OK) when:

• A Target SIL (Target PFD) is available;

• The required Subsystems are added (based on SIF type); and

• The Process Safety Time (PST) > 0 is entered (see Starting New SIF Analyses).
