Chattanooga Fire Department

Welcome to the Chattanooga Fire Department Dashboard. Here you will find data measurements collected and used to help ensure that our department is providing the best service possible to the City of Chattanooga. Measurements are updated daily so check back often. 

Average Response Time

For the most part, average response time for units first on scene since the start of the fiscal year has been increasing in the first few months and leveling out recently at 5 minutes and 22 seconds.  Both Red and Blue shifts show fairly level in-district response times.  Green shift has had a steady increase in Response times at the first half of the fiscal year, but has leveled out in the second half at 5 minutes and 27 seconds.

Monthly Average Response, Travel, and Turnout

Below is a time chart of monthly average Response, Turnout, and Travel times for the units first arriving on scene.  From the chart, it is apparent that turnout time has remained fairly consistent while upticks in Response times in September and November were driven by Travel time increases.  Filtering by only Green shift, the increase in Response time since the start of the year seems to driven almost exclusively by Travel time, not Turnout.

Monthly Distribution of Call Types 

The charts below are a distribution chart of the call types each month.  From the distribution chart, it is apparent the distribution of types of call is fairly consistent other than November's increase in Service Calls and decrease in False Alarm Calls. 

Building Fires

A critical performance measure CFD tracks is the amount of building fires that occur.  Fires that are NFIRS Code 111,112,121-123 are considered building fires.  The annual goal CFD is trying to stay under for FY19 is 180 building fires, which computes to 15 building fires per month.  The data shows there is a bit of an uptick in building fires during the winter, which is a known trend in CFD.  The map below shows building fire locations in the past three years.

Q & A Map for High Response Times

Last 30 Days

The following map can be used to highlight response times over 7 minutes to better understand if data was entered incorrectly or the specific circumstances of the incident.  3.6% of all incidents have first on scene response times of 10 to 20 minutes according to the raw data in FDM.

High Response Time Types

The top three types of calls taking between 10 and 20 minutes for the first unit to arrive based on the data are Assist Invalid calls, EMS  Calls Excluding Vehicle Accidents with Injuries, and Medical Assists.  The section marked as (Other) for 23% of the calls consists of many different types of calls that are less than 2% each of all the 10 to 20 minute incident volume.

554 Incidents

Assist Invalid calls, NFIRS Code 554, have been steadily increasing over the years as the population ages.  CFD is actively working on several programs to reduce the amount of times a full response is needed and mitigate the number of 554's CFD responds to.

Mutual Aid

In October of 2018, the City of Chattanooga officially joined surrounding Fire departments in the community in a commitment to deliver mutual aid.  When extra units are needed within Chattanooga and surrounding areas have availability, they will respond, and when surrounding areas need support, Chattanooga will respond.  Below are the cumulative counts of Mutual Aid Given vs Mutual Aid Received for the fiscal year to date.
