Fault Condition Hazard: correct answers A hazard that results from some failure or misuse. Most
hazards are the result of some failure mode. An example would be if an angioplasty balloon
bursts during use.
Normal Condition Hazard: correct answers This type of hazard does not result from some failure
or misuse but rather is inherent from its intended use and design. An example is the sharp blade
of a scalpel that is a potential source of harm to users.
"Inherent by Design" (in the context of risk control) correct answers Trying to design away risk.
Needle with spring loaded cover that activates once used
FMEA: correct answers 'Failure Mode and Effects Analysis'
A step-by-step approach for identifying all possible failures in a design, a manufacturing or
assembly process, or a product or service.
