Section Three: Risk Assessment <br /> <br /> Ambulance Response Zones are areas within an Ambulance Service Area, <br /> established by Lane County for the purpose of measuring response time <br /> compliance with the Ambulance Service Area Plan. <br /> <br /> Community Profile -- an analysis of the attributes of the community based on the <br /> unique mixture of demographics, socioeconomic factors, occupancy risk, demand zones, <br /> historical trends, and level of service currently being provided. <br /> <br />Through a methodical analysis of the risk dynamics present in the community, a risk assessment <br />makes it possible to develop logical resource deployment strategies to meet the identified needs. <br />The goal of the risk assessment process is to determine the probability of an event occurring, as <br />well as the potential consequences of that event. Decisions regarding resource deployment can <br />then follow in a logical sequence. <br /> <br />Risk Assessment Matrix <br /> <br />The matrix below shows the elements of consideration in risk assessment. They arc <br />combinations of the probability of an event occurring and the consequences should that event <br />occur. This tool divides risk assessment into four quadrants. Each quadrant of the chart <br />represents different requirements in the community for the commitment of emergency resources. <br /> <br /> High Probability High Probability <br /> ~.~ Low Consequence High Consequence <br /> <br /> ~'q Moderate Maximum <br /> ~ Risk Risk <br /> <br />< <br />~1~ Low High/Special <br /> Isolated Risk Risk <br />~ Low Probability Low Probability <br /> Low Consequence High Consequence <br /> <br /> CONSEQUENCES <br /> <br />A community risk assessment may include defining the inherent differences between a single- <br />family dwelling, a multiple-family dwelling, a large industrial occupancy or commercial campus, <br />and a high-rise residential or commercial structure, and then assigning each to a different <br />quadrant of the risk assessment matrix. Fire stations and emergency apparatus may be <br />distributed uniformly throughout the community to provide prompt initial response to all types of <br />incidents, or resources may be concentrated in high-consequence areas to enable a large-scale <br /> <br /> <br />
