ABSTRACT
Safety techniques fall into two categories: Hazard Analysis (HA) and Failure Analysis (FA). Faults, analyzed in the Fault Tree Analysis (FTA) technique, are tied to failure analysis through a coordinated specialty engineering effort. FA is performed using the Failure Modes and Effects Analysis (FMEA) and Failure Modes and Effects Criticality Analysis (FMECA) techniques. FA is a specialty engineering responsibility of reliability engineering. Just as the integration of systems engineering and safety is done in the SEMP, roles and responsibilities of reliability engineering, quality assurance and quality control, and other areas of respective specialty engineering that must integrate into safety management of the system, must be integrated throughout the life cycle in the System Safety Management Plan (SSMP), known in some industries as the Product Safety Plan (PSP). Figure 3.1 shows a sample SSMP. Safety Management is discussed in Section 3.3.
