Balancing Assessment with Planning Capabilities of a Local Emergency Response Organization The capabilities of emergency response planning organizations vary greatly. Some have access to very detailed assessment tools at every fire station, and larger metropolitan areas have emergency response personnel with extensive training and experience in emergency response.

Defining the Risk Metric While a planning agency may be able to qualitatively determine broad relationships regarding the risk of certain materials and the ability of existing emergency response teams to mitigate the consequences of releases, using a defined process with as many quantitative elements as possible helps to establish a sound basis for policy decisions related to response coverage. The approach outlined in this Guide uses a relative risk metric to capture and integrate all of the elements that contribute to the community's risk and to inform those policy decisions.

This enables the effectiveness of the emergency response to be captured in the response time and emergency response capability terms in the risk equation. For each scenario in the hazardous materials portfolio, both population and environmental consequences will be estimated and the maximum of the two estimates will be used in the risk equation.

The remaining 11 steps develop successive terms in the risk metric equation. The terms in the risk metric equation that are defined in Chapter 1 are displayed in brackets above the steps where the terms are quantified.
