About 5AlarmData

For years, I worked as a data scientist and engineer at a company that built analytics platforms for fire departments across California. I helped configure and manage our Tableau Server and Postgres database and built a client-facing portal that let departments interact with their own incident data through custom visualizations. We ingested latitude and longitude data from ArcGIS and developed hexbin and polygon mapping logic to plot incidents on a map by county.

Most departments have been collecting incident data for many years. The people responsible for doing something with it are the same people responding to calls, managing staff, and standing in front of city council. Nobody has time to run queries. There's rarely even a dedicated admin. Chiefs are spending evenings and weekends to pull numbers from their RMS and manually running reports.

Small and mid-size fire departments are dealing with more paperwork than ever: NERIS reporting, grant applications, ISO reviews, budget justifications. 5AlarmData gives fire departments faster insights from their NERIS data and helps with the recurring reporting that eats up their time.

Beta Program

We're looking for fire departments to help us build this.

5AlarmData is still in beta. We're looking for a small group of fire departments to stress-test the platform: run real data through it, tell us what's broken, and push back on anything that doesn't match how your department actually works.

In exchange, you get free lifetime access. No credit card, no trial period, no expiration. We get honest feedback from the people who actually use this data.

We're also working on direct NERIS API integration so you won't have to export a CSV at all: connect once and your data stays current automatically.
