For individual assets or facilities, the potential consequences are considered through a number of
parameters that quantify impacts or effects associated with failure or disruption of the project.
All questions are answered based on the consequences for a specific facility.
In the case of a system of multiple assets, the loss, failure, or disruption of any one individual
asset may trigger consequences affecting the ability of the entire system to meet the critical
function. Therefore, when estimating consequences, the impact of losing the entire system
should be considered rather than the consequences of each individual component. Each asset of
the system that could result in human impact will be evaluated individually however, the
economic consequences and impacts on critical functions represents a reasonable worst case for
the entire system
