Domains of HSI - System Safety
The
system safety domain involves the
application of engineering and management principles, criteria, and
techniques to optimize all aspects of safety within the constraints of
operational effectiveness, time, and cost throughout all phases of the
system life cycle.
Safety factors consist of those system design characteristics that serve to
minimize the potential for mishaps causing death or injury to operators,
maintainers and supporters or threaten the survival and/or operation of the
system or cause cascading failures in other systems. Prevalent issues
include factors that threaten the safe operation and/or survival of the
platform; walking and working surfaces including work at heights; pressure
extremes; and control of hazardous energy releases such as mechanical,
electrical, fluids under pressure, ionizing or non-ionizing radiation (often
referred to as "lock-out/tag-out"), fire, and explosions.
Safety analyses and lessons learned are used to aid in development of design
features that prevent safety hazards to the greatest extent possible and
manage safety hazards that cannot be avoided. For more
information on the Safety domain, refer to the
Defense Acquisitions Handbook, 6.3.5.
