Criteria for Distribution of Companies To reduce property damage from a fire, the firefighters need to get to the scene quickly. Therefore, ISO evaluates the distribution of fire stations in each community. Item 560 of the Fire Suppression Rating Schedule (FSRS) provides the criteria: 560. DISTRIBUTION OF COMPANIES (DC): The built-upon area of the city should have a first-due engine company within 1-1/2 miles and a ladder-service company within 2-1/2 miles. ISO establishes "standard response districts" around each existing fire station. The standard response district for an engine company is a polygon defined by streets leading from the fire station out to a distance of 1.5 road miles. For a ladder-service company, the standard response district is a polygon defined by streets out to a distance of 2.5 road miles. For each fire station, we count the fire hydrants within the standard response district. When fire hydrants are not available, we measure the total linear road miles in the standard response district. We then identify contiguous built-upon areas in the community that do not have a fire station within the specified distance. If such an area has at least 50 percent of the number of fire hydrants (or, in areas without hydrants, 50 percent of the linear road miles) found in the standard response district, we consider that the area may need a fire station.

Response-Time Considerations In evaluating a community's public fire protection, ISO considers the distribution of fire companies. Generally, ISO's criteria say that a built-upon area of a community should have a first-due engine company within 1.5 road miles of the protected properties and a ladder-service company within 2.5 road miles. Those benchmark criteria produce an expected response time of 3.2 minutes for an engine company and 4.9 minutes for a ladder-service company, based on a formula developed by the RAND Corporation. RAND conducted extensive studies of fire department response times. They concluded that the average speed for a fire apparatus responding with emergency lights and siren is 35 mph. That speed considers average terrain, average traffic, weather, and slowing down for intersections. Taking into account the average speed and the time required for an apparatus to accelerate from a stop to the travel speed, RAND developed the following equation for calculating the travel time:

T = 0.65+1.7D

where

T = time in minutes to the nearest 1/10 of a minute 0.65 = a vehicle-acceleration constant for the first 0.5 mile traveled 1.7 = a vehicle-speed constant validated for response distances ranging from 0.5 miles to 8.0 miles. D = distance
