Risk-Based Inspection

The units for affected area consequence (square feet or square meters) do not
readily translate into our everyday experiences and thus there is some
reluctance to use this measure. It has, however, several features that merit
consideration. The affected area approach has the characteristic of being able
to compare toxic and flammable consequences by relating to the physical area
impacted by a release. A drawback for area consequences is that it does not
include the business impact of failure, which can often be the largest portion of
total consequence.
