consideration of consequences within a certain distance from the hazardous material
release point.
Another important consideration in the development of this standard is the focus on
analyzing the risk, as opposed to estimating the risk. This may seem to be a purely
semantic distinction, but it emphasizes that application of this standard is intended to
provide an organization (whether it be the facility operator or some cognizant safety
oversight organization) with sufficient information to make a decision about the extent to
which releases following an aircraft crash are a safety concern. It is also intended to
provide sufficient information to identify where the risk is coming from and to determine
what actions, if any, would be prudent to reduce the frequency or to mitigate the
consequences of an aircraft crash into the facility. In most cases, this does not require an
accurate estimate of the risk. Rather, it is sufficient to determine that the risk (or the
individual subelements of frequency and consequences) does not exceed a
predetermined level of concern (i.e., it is not large compared to other risks).
This standard allows the analysis to proceed along a series of increasingly complex steps;
the results at each step are used to determine whether it is necessary to proceed to the
next step or whether sufficient information has been provided and the analysis can be
stopped and documented. As one proceeds through the steps, the results will get closer
to an actual estimate of the risk, but even after fully implementing this standard, the results
will still be more conservative than would be expected from a best-estimate risk
assessment. In summary, following this standard will, in the vast majority of cases,
provide sufficient information to document facility safety and support sound decision
making for addressing the effects of an aircraft crash in the context of facility safety. In
those rare cases where additional analysis is considered necessary to achieve these
goals, an organization may perform a more detailed analysis. This standard does not
provide guidance on completing such an analysis.
A necessary corollary to the above discussion is that this is not a criterion-based standard.
It does not provide any hard and fast rules prescribing what actions should be taken in
response to the results; it does not even prescribe whether any action should be
considered. It does provide quantitative guidelines against which the results for each step
