18.104.22.168 Preliminary Hazard List
This element is a preliminary hazard list (PHL) identifying
any especially hazardous areas for added management emphasis. The PHL should
be developed very early in the development phase of an item.
22.214.171.124 Preliminary Hazard Analysis
The purpose of the Preliminary Hazard Analysis (PHA) is to
identify safety critical areas, evaluate hazards, and identify the safety
design criteria to be used.
126.96.36.199 Safety Requirements/Criteria Analysis
The Safety Requirements/Criteria Analysis (SRCA) relates the
hazards identified to the system design and identifies or develops design
requirements to eliminate or reduce the risk of the hazards to an acceptable
level. The SRCA is based on the PHL or PHA, if available. The SRCA is also
used to incorporate design requirements that are safety related but not tied
to a specific hazard.
188.8.131.52 Subsystem Hazard Analysis
The Subsystem Hazard Analysis (SSHA) identifies hazards
associated with design of subsystems including component failure modes,
critical human error inputs, and hazards resulting from functional
relationships between components and equipments comprising each
184.108.40.206 System Hazard Analysis
The System Hazard Analysis (SHA) documents the primary safety
problem areas of the total system design including potential safety critical
220.127.116.11 Operating and Support Hazard Analysis
The Operating and Support Hazard Analysis (O&SHA)
identifies associated hazards and recommends alternatives that may be used
during all phases of intended system use.
18.104.22.168 Occupational Health Hazard Assessment
The Occupational Health Hazard Assessment (OHHA) identifies
human health hazards and proposes protective measures to reduce the
associated risks to levels acceptable to the managing
