Set by the NFPA as structure's risk of fire based occupancy and structure type, in FireCARES this is captured at a per parcel record level.
-
High-Hazard Occupancies – High-rise buildings, hospitals, schools, nursing homes, explosive plants, refineries, public assembly structures, and other high life hazard or large fire potential occupancies.
-
Medium-Hazard Occupancies – Apartments, offices, mercantile and industrial occupancies that may require extensive use of fire fighting forces.
-
Low-Hazard Occupancies – One-, two- or three-family dwellings and scattered small business and industrial occupancies.
Likelihood of an event happening within a specific area using NFORS historical event data as a benchmark for comparison.
Single tract of land w/ one or more structures, based on ownership.
In FireCARES, fire departments with similar size, binned on protected population size and region.
Area of responsibility for a single fire department.
Segments geographic areas by population count, target population size of a single census tract is 5000 people. Departments that handle the most calls in a census tract is the “owner” of that census tract in FireCARES.
N-ranking (quartile) of fire department performance against fire risk, fire spread and death & injuries as compared with similar fire departments. Split into 4 buckets, but categorized as "good", "fair" or "poor" based on comparison to similar departments. National Assessment of performance score based on the fire spread/death and injury risk takes into account all departments with the same "low", "medium", etc risk levels for those dimensions.
Comparison with similar fire departments (uses building fires from NFORS database), count # of building fires w/ fire spread binned and modeled for residential structures in terms of time to spread.
